The following sections provide a list of available advanced attributes available for controlling and customizing 3D Column chart elements.
NoteThis article contains documentation for advanced attributes which are third-party customizations that must be manually entered into the chart wizard. These articles were converted directly from the documentation provided by this third-party source. Not every attribute listed may be supported in Exago BI as some unexpected conflicts may occur in their integration within the application.
Functional Attributes
These attributes let you control a variety of functional elements on the chart. For example, you can opt to show/hide data labels, data values. You can also set chart limits and extended properties.
| Attribute | Type | Value | Description |
|---|---|---|---|
| animation | True/False | 0/1 | This attribute gives you the option to control animation in your charts. If you do not want to animate any part of the chart, set this as 0. |
| animationDuration | Number | In seconds | This attribute sets the animation duration of the chart. `animationDuration` attribute is applicable only if animation of the chart is enabled. Default value: 1 sec |
| palette | Number | 1-5 | Exago introduces the concept of Color Palettes. Each chart has 5 pre-defined color palettes which you can choose from. Each palette renders the chart in a different color theme. |
| paletteColors | Text | List of hex color codes separated by comma | While the `palette` attribute allows to select a palette theme that applies to chart background, canvas, font and tool-tips, it does not change the colors of data items (i.e., column, line, pie etc.). Using `paletteColors` attribute, you can specify your custom list of hex colors for the data items. The list of colors have to be separated by comma e.g., `"paletteColors": "#FF0000, #0372AB, #FF5904..."`. The chart will cycle through the list of specified colors and then render the data plot accordingly. To use the same set of colors throughout all your charts in a web application, you can store the list of palette colors in your application globally and then provide the same in each chart JSON. |
| showLabels | True/False | 0/1 | It sets the configuration whether the x-axis labels will be displayed or not. |
| maxLabelHeight | Number | In Pixels | This attribute can be used to set the maximum height for the x-axis labels (data labels) excluding the x-axis title. If any label goes beyond this height, the label will be truncated. In stagger mode, the number of stagger lines will be reduced if they exceed this value. |
| labelDisplay | Text | 'AUTO', 'WRAP', 'STAGGER', 'ROTATE', 'NONE' | Using this attribute, you can customize the alignment of data labels (x-axis labels). There are 5 options: AUTO, WRAP, STAGGER, ROTATE or NONE. By default, this attribute is set to AUTO mode which means that the alignment of the data labels is determined automatically depending on the size of the chart. WRAP wraps the label text if it is too long to fit in one line. ROTATE rotates the labels vertically. STAGGER divides the labels into multiple lines. |
| useEllipsesWhenOverflow | True/False | 0/1 | When enabled in auto mode, long data labels are truncated by adding ellipses to prevent them from overflowing the chart background. The default value is 1. |
| rotateLabels | True/False | 0/1 | This attribute lets you set whether the data labels will show up as rotated labels on the chart. |
| slantLabels | True/False | 0/1 | If you've opted to show rotated labels on chart, this attribute lets you set the configuration whether the labels will show as slanted labels or fully vertical ones. |
| labelStep | Number | 1 or above | By default, all the labels are displayed on the chart. However, if you've a set of streaming data (like name of months or days of week), you can opt to show every n-th label for better clarity. This attribute just lets you do so. When a value greater than 1 (n) is set to this attribute, the first label from left and every label at the n-th position from left will be displayed. e.g., a chart showing data for 12 months and set with `labelStep: 3` will show labels for January, April, July, and October. The rest of the labels will be skipped. |
| staggerLines | Number | 2 or above | If you've opted for STAGGER mode as `labelDisplay`, using this attribute you can control how many lines to stagger the label to. By default, all labels are displayed in a single line. |
| showValues | True/False | 0/1 | Sets the configuration whether data values will be displayed along with the data plot on chart. |
| rotateValues | True/False | 0/1 | If you've opted to show data values, you can rotate them using this attribute. |
| placeValuesInside | True/False | 0/1 | If you've opted to show data values, you can show them inside the columns using this attribute. By default, the data values show outside the column. |
| showLimits | True/False | 0/1 | Whether to show chart limit values. If not specified `showYAxisValues` attribute overrides this value. |
| showDivLineValues | True/False | 0/1 | Whether to show div line values. If not specified `showYAxisValues` attribute overrides this value. |
| showShadow | True/False | 0/1 | Whether to show column shadows. |
| adjustDiv | True/False | 0/1 | Exago automatically tries to adjust divisional lines and limit values based on the data provided. However, if you want to set your explicit lower and upper limit values and number of divisional lines, first set this attribute to false. That will disable automatic adjustment of divisional lines. |
| clickURL | Text | Any | The entire chart can now act as a hotspot. Use this URL to define the hotspot link for the chart. The link can be specified in Exago Link format. |
| clickURLOverridesPlotLinks | True/False | 0/1 | Sets whether the `clickURL` attribute (that sets a link to which the user is directed when the chart is clicked) overrides the `link` attribute (that sets a link to which the user is directed when a data plot is clicked). Default value: 0 (`clickURL` does not override `link`) |
| maxColWidth | Number | In Pixels | Maximum allowed column width |
| use3DLighting | True/False | 0/1 | Whether to use advanced gradients and shadow effects to create better looking 3D charts. |
| setAdaptiveYMin | True/False | 0/1 | This attribute lets you set whether the y-axis lower limit will be 0 (in case of all positive values on chart) or should the y-axis lower limit adapt itself to a different figure based on values provided to the chart. |
| useDataPlotColorForLabels | True/False | 0/1 | Uses the same data plot color for data labels. |
| hasRTLText | Number | Any | This attribute, when set to `1`, indicates to the chart that the text (rendered on the chart) may contain RTL characters and the textual display has to be managed accordingly. |
| showPrintMenuItem | True/False | 0/1 | Whether to show "Print Chart" item in the context menu of the chart? Even if you opt to hide the item in context menu, you can still opt to invoke `print()` JavaScript method of the chart to print the same. |
| theme | Text | 'fusion', 'gammel', 'candy', 'ocean', 'zune', 'carbon', 'umber' | This attribute changes the theme of the chart. There are 7 types of themes which have been made according to the different color combinations. |

Number Formatting
Exago offers you a lot of options to format your numbers on the chart. Using the attributes below, you can control a myriad of options like: Formatting of commas and decimals Number prefixes and suffixes Decimal places to which the numbers will round to Scaling of numbers based on a user defined scale Custom number input formats
| Attribute | Type | Value | Description |
|---|---|---|---|
| formatNumber | True/False | 0/1 | This configuration determines whether the numbers displayed on the chart will be formatted using commas, e.g., 40,000 if 'formatNumber': '1'; and 40000 if 'formatNumber': '0';. |
| formatNumberScale | True/False | 0/1 | Configuration whether to add K (thousands) and M (millions) to a number after truncating and rounding it - e.g., if `formatNumberScale` is set to 1, 1043 will become 1.04K (with decimals set to 2 places). Same with numbers in millions - an M will be added at the end. |
| defaultNumberScale | Text | Any | The default unit of the numbers that you're providing to the chart. |
| numberScaleUnit | Text | Any | Unit of each block of the scale. |
| numberScaleValue | Text | Any | Range of the various blocks that constitute the scale. |
| forceNumberScale | True/False | 0/1 | If a data value is less than the lowest given number is the number scale, this attribute forces the lower value of the `numberScaleUnit` to be applied to that data value. This attribute works only when `“formatNumberScale”: “1”` and the `defaultNumberScale` attribute is not defined. For example, if `“numberScaleUnit”: “K, M”`, `“numberScaleValue”: “1000, 1000”`, and `“forceNumberScale”: “1”`, a data value of `400` will be rendered as `0.40K`. |
| scaleRecursively | True/False | 0/1 | Whether recursive scaling should be applied. |
| maxScaleRecursion | Number | Any | How many recursions to complete during recursive scaling? -1 completes the entire set of recursion. |
| scaleSeparator | Text | Any | What character to use to separate the scales that are generated after recursion? |
| numberPrefix | Text | Character | Using this attribute, you could add prefix to all the numbers visible on the graph. For example, to represent all dollars figure on the chart, you could specify this attribute to $ to show like $40000, $50000. |
| numberSuffix | Text | Character | Using this attribute, you could add a suffix to all the numbers visible on the graph. For example, to represent all figures quantified as per annum on the chart, you could specify this attribute to '/a' to show like 40000/a, 50000/a. |
| decimalSeparator | Text | Character | This attribute helps you specify the character to be used as the decimal separator in a number. |
| thousandSeparator | Text | Character | This attribute helps you specify the character to be used as the thousands separator in a number. |
| thousandSeparatorPosition | Number | This option helps you specify the position of the thousand separator. | |
| inDecimalSeparator | Text | Character | In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number. So, Exago accepts the input decimal and thousand separator from user, so that it can convert it accordingly into the required format. This attribute lets you input the decimal separator. |
| inThousandSeparator | Text | Character | In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give an error while converting to number. So, Exago accepts the input decimal and thousand separator from user, so that it can convert it accordingly into the required format. This attribute lets you input the thousand separator. |
| decimals | Number | 0-10 | Number of decimal places to which all numbers on the chart will be rounded to. |
| forceDecimals | True/False | 0/1 | Whether to add 0 padding at the end of decimal numbers. For example, If you limit the maximum number of decimal digits to 2, a number like 55.345 will be rounded to 55.34. This does not mean that all numbers will be displayed with a fixed number of decimal places. For instance 55 will not be displayed as 55.00 and 55.1 will not become 55.10. In order to have fixed number of decimal places attached to all the numbers, set this attribute to 1. |
Font Properties
Using the attributes below, you can define the generic font properties for all the text on the chart. These attributes allow you a high level control over font properties. If you intend to specify font properties for individual chart elements (like Caption, sub-caption etc.), you'll need to use the Styles feature of Exago. Using Styles, you can also specify advanced font properties like Bold, Italics, HTML Mode etc.
| Attribute | Type | Value | Description |
|---|---|---|---|
| baseFont | Text | Font Name | This attribute lets you set the font face (family) of all the text (data labels, values etc.) on chart. If you specify the `outCnvBaseFont` attribute also, then this attribute controls only the font face of text within the chart canvas bounds. |

Chart Padding & Margins
The following attributes help you control chart margins and paddings. Exago allows you to manually customize the padding of various elements on the chart to allow advanced manipulation and control over chart visualization. Padding in Exago is always defined in pixels, unless the attribute itself suggests some other scale (like `plotSpacePercent`, which configures the spacing using percentage values). You can also define the chart margins. Chart Margins refer to the empty space left on the top, bottom, left and right of the chart. That means, Exago will not plot anything in that space. It's not necessary for you to specify any padding/margin values. Exago automatically assumes the best values for the same, if you do not specify the same.
| Attribute | Type | Value | Description |
|---|---|---|---|
| captionPadding | Number | In Pixels | This attribute lets you control the space (in pixels) between the sub-caption and top of the chart canvas. If the sub-caption is not defined, it controls the space between caption and top of chart canvas. If neither caption, nor sub-caption is defined, this padding does not come into play. |
| xAxisNamePadding | Number | In Pixels | Using this, you can set the distance between the top end of x-axis title and the bottom end of data labels (or canvas, if data labels are not to be shown). |
| yAxisNamePadding | Number | In Pixels | Using this, you can set the distance between the right end of y-axis title and the start of y-axis values (or canvas, if the y-axis values are not to be shown). |
| yAxisValuesPadding | Number | In Pixels | This attribute helps you set the horizontal space between the canvas left edge and the y-axis values or trend line values (on left/right side). This is particularly useful, when you want more space between your canvas and y-axis values. |
| labelPadding | Number | In Pixels | This attribute sets the vertical space between the labels and canvas bottom edge. If you want more space between the canvas and the x-axis labels, you can use this attribute to control it. |
| valuePadding | Number | In Pixels | It sets the vertical space between the end of columns and start of value textboxes. This basically helps you control the space you want between your columns/anchors and the value textboxes. |
| plotSpacePercent | Number | 0-80 (In Percent) | On a column chart, there is spacing defined between two columns. By default, the spacing is set to 20% of canvas width. If you intend to increase or decrease the spacing between columns, you can do so using this attribute. For example, if you wanted all columns to stick to each other without any space in between, you can set `plotSpacePercent` to 0. Similarly, if you want very thin columns, you can set `plotSpacePercent` to its max value of 80. |
| chartLeftMargin | Number | In Pixels | Amount of empty space that you want to put on the left side of your chart. Nothing is rendered in this space. |
| chartRightMargin | Number | In Pixels | Amount of empty space that you want to put on the right side of your chart. Nothing is rendered in this space. |
| chartTopMargin | Number | In Pixels | Amount of empty space that you want to put on the top of your chart. Nothing is rendered in this space. |
| chartBottomMargin | Number | In Pixels | Amount of empty space that you want to put at the bottom of your chart. Nothing is rendered in this space. |
| canvasLeftMargin | Number | In Pixels | This attribute lets you control the space between the start of chart canvas and the start (x) of chart. In case of 2D charts, the canvas is the visible rectangular box. In case of 3D charts, the canvas box is the imaginary box around the 3D canvas. Using this attribute, you can control the amount of empty space between the chart left side and canvas left side. By default, Exago automatically calculates this space depending on the elements to be placed on the chart. However, if you want to over-ride this value with a higher value, you can use this attribute to specify the same. Please note that you cannot specify a margin lower than what has been calculated by the chart. This attribute is particularly useful, when you've multiple charts placed in a page and want all their canvas start position to align with each other - so in such a case, you can set same margin value (a value large enough that it doesn't get rejected by chart owing to it being lower than the calculated value) for all such charts in the page. |
| canvasRightMargin | Number | In Pixels | Like `canvasLeftMargin`, this attribute lets you set the space between end of canvas and end of chart. |
| canvasTopMargin | Number | In Pixels | Like `canvasLeftMargin`, this attribute lets you set the space between top of canvas and top of chart. |
| canvasBottomMargin | Number | In Pixels | Like `canvasLeftMargin`, this attribute lets you set the space between bottom of canvas and bottom of chart. |
The data Object
In single-series charts, each instance of the `data` object represents a data value to be plotted on the chart. For a single-series chart, one instance of the `data` object looks as shown in the example below:
"data"[{
"label": "Jan",
"value": "10000"
}]
Attributes of the `data` object are used to set and configure the data values for the chart.
| Attribute | Type | Value | Description |
|---|---|---|---|
| alpha | Number | 0 - 100 | This attribute determines the transparency of a data item. The range for this attribute is 0 to 100. 0 means complete transparency (the data item wont be shown on the graph) and 100 means opaque. |
| color | Color | Hex Color Code | If you want to define your own colors for the data items on chart, use this attribute to specify color for the data item. |

| label | Text | Any | This attribute determines the label for the data item. The label appears on the x-axis of chart. Note: The `label` attribute replaces the `name` attribute. Previously, either one of the attributes could be used to set the label. Support for the `name` attribute has been discontinued since v3.10.0. |
| link | Text | Any | You can define links for individual data items. That enables the end user to click on data items (columns, lines, bars etc.) and drill down to other pages. To define the link for data items, use the link attribute. You can define links that open in same window, new window, pop-up window or frames. Please see "Drill-Down > Using JavaScript Functions as Links" for more information. Also, you'll need to Url Encode all the special characters (like ? and &) present in the link. |

Vertical Data Separator Lines
Vertical data separator lines help you separate data blocks. These lines run through the height of the chart, thereby segregating the data into two different blocks. Vertical lines are defined as shown in the example below:
"data": [{
"label": "Grade 1",
},
{
"vLine": "true",
"label": "Appraisal"
}]
}]
You can configure the cosmetics of vertical separator lines using the following attributes:

| vLine | Text | Any | Set this attribute to `true` to render a vertical data separator line. |
| color | Color | Hex Color Code | This attribute defines the color of vertical separator line |
| thickness | Number | In Pixels | Thickness in pixels of the vertical separator line. |
| alpha | Number | 0 - 100 | Alpha of the vertical separator line. |
| dashed | True/False | 0/1 | Whether the vertical separator line should be rendered as dashed lines. Default value: 0 (vertical separator line rendered using straight lines) |
| dashLen | Number | In pixels | Sets the width of each dash when vertical separator line is rendered as dashed lines. |
| dashGap | Number | In pixels | Sets the gap between consecutive dashes when vertical separator line is rendered as dashed lines. |
| label | Text | Label for the vertical separator line, if to be shown. Note: The `label` attribute replaces the `name` attribute. Previously, either one of the attributes could be used to set the label. Support for the `name` attribute has been discontinued since v3.10.0. |
|
| showLabelBorder | True/False | 0/1 | Whether to show a border around the vLine label. |
| linePosition | Number | 0-1 | Helps configure the position of vertical line i.e., if a vLine is to be plotted between 2 points Jan and Feb, user can set any position between 0 and 1 to indicate the relative position of vLine between these two points (0 means Jan and 1 means Feb). By default, it’s 0.5 to show in between the points. |
| labelPosition | Number | 0-1 | Helps configure the position of the vLine label by setting a relative position between 0 and 1. In vertical charts, 0 means top of canvas and 1 means bottom. In horizontal charts, 0 means left of canvas and 1 means right. |
| labelHAlign | Text | left, center, right | Horizontal anchor point for the alignment of vLine label. |
| labelVAlign | Text | top, middle, bottom | Vertical anchor point for the alignment of vLine label. |
Trend-lines
Trend-lines are horizontal lines that aid in interpretation of data with respect to some pre-determined value. For example, if you are plotting the sales data for the current year, you might want to show the previous year's average monthly sales as a trend indicator for ease of comparison. The `lines` object, child of the `trendlines` object is used to add trend-lines to a chart. Although the `line` object has to be defined within the `trendlines` object, the latter cannot be used to collectively customize trend-lines, because it does not have any attributes of its own. The attributes of the `lines` object, child of the `trendlines` object, are used to create and customize trend-lines for charts.
| Attribute | Type | Value | Description |
|---|---|---|---|
| startValue | Number | Numeric Value | The starting value for the trendline. Say, if you want to plot a slanted trendline from value 102 to 109, the `startValue` will be 102. |
| endValue | Number | Numeric Value | The ending y-axis value for the trendline. Say, if you want to plot a slanted trendline from value 102 to 109, the `endValue` will be 109. If you do not specify a value for `endValue`, it will automatically assume the same value as `startValue`. |
| displayValue | Text | Any | If you want to display a string caption for the trend line by its side, you can use this attribute. Example: `displayValue='Last Month High'`. When you don't supply this attribute, it automatically takes the value of `startValue`. |
| color | Text | Hex Color Code | Color of the trend line and its associated text |
| isTrendZone | True/False | 0/1 | Whether the trend will be displayed as a line or a zone (fill-colored rectangle). |
| thickness | Number | In Pixels | If you've opted to show the trend as a line, this attribute lets you define the thickness of trend line. |
| alpha | Number | 0 - 100 | Alpha of the trend line. |
| dashed | True/False | 0/1 | Whether the trendline should be rendered as dashed lines. Default value: 0 (trendline rendered using straight lines) |
| dashLen | Number | In pixels | Sets the width of each dash when trendline is rendered as dashed lines. |
| dashGap | Number | In pixels | Sets the gap between consecutive dashes when trendline is rendered as dashed lines. |
| valueOnRight | True/False | 0/1 | Whether to show the trend line value on left side or right side of chart. This is particularly useful when the trend line display values on the chart are colliding with divisional lines values on the chart. |
| toolText | Text | Custom tool-text for this trendline/zone. |
Trend-lines (Chart level attributes)
Trend-lines are horizontal lines that aid in interpretation of data with respect to some pre-determined value. For example, if you are plotting the sales data for the current year, you might want to show the previous year's average monthly sales as a trend indicator for ease of comparison. Cosmetics for all the trend-lines rendered can be attained using this set of attributes. Although there are set of attributes of the `line object`, used to create and customize trend-lines, these set of attributes effect all the trend-lines rendered in your chart.
| Attribute | Type | Value | Description |
|---|---|---|---|
| trendlineColor | Color | Hex Color Code | Sets color of all the trend lines and its associated text in the chart. |
| trendlineThickness | Number | In Pixels | If you've opted to show the trend as a line, this attribute lets you define the thickness of all the trend lines in your chart. |
| trendlineAlpha | Number | 0 - 100 | Sets transparency for all the trend lines in your charts. |
| trendLineToolText | Text | Any | Sets the tooltip text of the trend-line. It accepts macros, plain text, and HTML tags, as string. |
Trend-lines Display Value Cosmetics
These attributes let you customize the text displayed with a trend-line.
Note: These attributes belong to the `chart` object and not to the `line` object (child of the `trendline` object). They are, therefore, applied to all trend-lines on your chart.
