The following sections provide a list of available advanced attributes available for controlling and customizing Heatmap 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 or 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 | 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 (that is, 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, for example, `"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. |
| 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. |
| trType | Text | Specifies the type of data provided in the top-right label. This value is displayed in the tool tip. | |

| blType | Text | Specifies the type of data provided in the bottom-left label. This value is displayed in the tool tip. | |
| staggerLines | Number | 2 or above | If you have 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 would be displayed along with the data plot on chart. |
| showLimits | True/False | 0/1 | Whether to show chart limit values. |

| unescapeLinks | True/False | 0/1 | Internally the chart decodes a Url that you set as link. Before invoking the link it again encodes the Url. If you are passing multilingual characters via a Url or do not want this decode-encode mechanism to be handled by chart you can set,`unescapeLinks='0'`. |
| showPrintMenuItem | True/False | 0/1 | When you right click on the chart it shows a context menu. This attribute allows you to show or hide the "Print" option in the context menu. |
| 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. |
| plotHighlightEffect | Text | Any | This attribute lets you enable/disable the highlight effect, in the form of a `fadeout`, for the data plots corresponding to a legend item. When this attribute is enabled and the mouse pointer is hovered over a legend item label, plots belonging to the other data series fadeout, by reducing their opacity. The fadeout effect can be customized by specifying the fadeout color and opacity using the `color` and `alpha` attributes. Eg. `fadeout|color=#ff0000, alpha=60` |

Chart Padding & Margins
The following attributes help you control chart margins and paddings. Exago allows you 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 would not plot anything in that space. It is not necessary for you to specify any padding or 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). |
| labelXPadding | Number | In Pixels | This attribute sets the vertical space between the x-axis labels and canvas bottom edge. |
| labelYPadding | Number | In Pixels | It sets the horizontal space between the y-axis labels and the canvas right edge. |
| 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. |
| legendPadding | Number | In Pixels | Padding of legend from right or bottom side of canvas |
| 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. Using this attribute, you can control the amount of empty space between the chart left side and canvas left side. By default, the chart 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 have 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 does not 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. |
Data Label Cosmetics
These attributes let you configure the cosmetics of all data labels of the chart.
| Attribute | Type | Value | Description |
|---|---|---|---|
| showLabels | True/False | 0/1 | It sets the configuration whether the categorical axis labels will be displayed or not. |
| maxLabelHeight | Number | In Pixels | This attribute can be used to set the maximum height for the categorical axis labels (data labels) excluding the 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. |
| maxLabelWidthPercent | Numeric | In Pixels | Restricts the maximum space allotted for the y-axis data labels with respect to the chart's width. If a data label is longer than the specified percentage width then it will either be wrapped or get truncated, subject to the availability of vertical space. Unnecessary space is not reserved for the labels. If all the labels are shorter than the specified maximum width, this value is not applied. |
| minLabelWidthPercent | Number | 1-100 | Restricts the minimum length of data labels in terms of percentage of the chart's width that the data labels can occupy. The space thus calculated stays reserved even if the label width is less than the minimum width. |
| labelDisplay | Text | 'AUTO', 'WRAP', 'STAGGER', 'ROTATE', 'NONE' | Using this attribute, you can customize the alignment of data labels (categorical 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. |

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 would 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, for example, 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 - for example, if `formatNumberScale` is set to 1, 1043 would 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 are 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, the chart 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, the chart 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 would 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. |
| baseFontSize | Number | 6 - 72 | This attribute sets the base font size of the chart, that is, all the values and the names in the chart which lie on the canvas will be displayed using the font size provided here. |
| baseFontColor | Color | Hex Color Code | This attribute sets the base font color of the chart, that is, all the values and the names in the chart which lie on the canvas will be displayed using the font color provided here. |

The rows Object and the row Object
While the `dataset` object and its child object, the `data` object can be used to define the rows and columns for a heat map chart, you have to be careful about the order of the values for the rows and columns. The `rows` object and its child object, the `row` object are used to create rows and predefine their order, enabling you to specify the data values in any order. Although the `row` object has to be defined within the `rows` object, rows cannot be collectively customized using the `rows` object, because it does not have any attributes of its own. These attributes let you define the order of rows for a heat map chart.
| Attribute | Type | Value | Description |
|---|---|---|---|
| id | Number/String | Any | Allows you to specify a unique Id for the rows. This id is used in the `data` object to place the data values in the pre-defined position. |
| label | Text | Any | Allows you to specify a label for the rows. If you do not specify the label the unique id will be displayed as the label for the rows in the 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. |
| showLabel | Text | Any | Allows you to show or hide the label of a particular row. |
The columns Object and the column Object
While the `dataset` object and its child object, the `data` object can be used to define rows and columns for a heat map chart, you have to be careful about the order of the values for the rows and columns. The `columns` object and its child object, the `column` object are used to create columns and predefine their order, enabling you to specify the data values in any order. Although the `column` object has to be defined within the `columns ` object, note that columns cannot be collectively customized because the `columns` object does not have any attributes of its own. These attributes let you define the order of columns for a heat map chart.
| Attribute | Type | Value | Description |
|---|---|---|---|
| id | Number/String | Any | Allows you to specify a unique Id for the columns. This id is used in the `data` object to place the data values in the pre-defined position. |
| label | Text | Any | Allows you to specify a label for the columns. If you do not specify the label the unique id will be displayed as the label for the rows in the 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. |
| showLabel | Text | Any | Allows you to show or hide the label of a particular column. |
The dataset Object and the data Object
The `dataset` object contains a series of data defined through the `data` object. There are no attributes for the `dataset` object. The attributes used for the `data` object are mentioned below:
| Attribute | Type | Value | Description |
|---|---|---|---|
| rowId | Text | Any | Specifies the position of the row where the data it is to be placed in the chart. If the `rows` object is used then it is mandatory to use the same id which is defined in the `row` object by the `id` attribute. |
| columnId | Text | Any | Specifies the position of the column where the data it is to be placed in the chart. If the `columns` object is used then it is mandatory to use the same id which is defined in the `column` object by the `id` attribute. |
| colorRangeLabel | Text | Any | This attribute is used to provide the color-range label which is defined in the `color` object of the `colorRange` object. It is used only in category based heat map chart. |
| value | Number | Any | This attribute allows you to display a value at the center of a data plot. |
| displayValue | Number/String | Any | Allows you to display any numeric value or string at the center of the dataplot. The settings of this attribute overwrites the settings of the ` value` attribute when both are used at the same time. |
| tlLabel | Number/String | Any | This attribute allows you to display a label on the top-left corner of a data plot. |
| trLabel | Number/String | Any | This attribute allows you to display a label on the top-right corner of a data plot. |
| blLabel | Number/String | Any | This attribute allows you to display a label on the bottom-left corner of a data plot. |
| brLabel | Number/String | Any | This attribute allows you to display a label on the bottom-left corner of a data plot. |
| color | Color | Hex Color Code | In Heat map chart, if you wish to highlight a particular cell, you can specify it's color at "set" level using this attribute. |
| 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 Charts > Exago Link format" for more information. Also, you need to Url Encode all the special characters (like ? and &) present in the link. |
| toolText | Text | Any | By default, the tooltip text for a data item in the heat map chart includes the values of the `trLabel`, `tlLabel`, `brlabel`, `bllabel`, `trType`, `tlType`, `brType`, and and `blType` attributes. Additionally, you can display more customized information using the `toolText` attribute. |
| showValue | True/False | 0/1 | You can individually opt to show or hide values of individual data items using this attribute. This value over-rides the data-set level value. |
| valueFontColor | Color | Hex Color Code | Specifies the font color of a data value for an individual data plot. |
| valueBgColor | Color | Hex Color Code | Sets the background color of a value text for an individual data plot. |
| valueBorderColor | Color | Hex Color Code | Sets the border color around the value text for an individual data plot. |
| alpha | Number | 0 - 100 | For Multi-series charts, you can define the alpha of data-sets at dataset level. However, if you wish to highlight a particular data element, you can specify its alpha at "set" level using this attribute. |
The colorRange Object
Attributes of the `colorRange` object for the heat map chart are used to define the type of legend, the lower limit of the scale, and the start and end labels. Note that the `colorRange` object is not used to collectively configure all ranges; the `color` object (child of the `colorRange` object) is used to do that.
| Attribute | Type | Value | Description |
|---|---|---|---|
| code | Color | Hex Color Code | Hex code of the color range using which it will be filled. |
| endLabel | Text | Any | Specifies the label for the upper limit of the gradient scale. |
| gradient | True/False | 0/1 | Allows you to display gradient legend. |
| mapByPercent | True/False | 0/1 | Allows you to display the data values in percentage. |
| minValue | Number | Any | Sets the minimum value or the lower limit of the numeric range and the gradient scale. |
| startLabel | Text | Any | Specifies the label for the lower limit of the gradient scale. |
The color Object
The attributes of the `color` object, child of the `colorRange` object, are used to configure individual ranges on the gauge scale.
| Attribute | Type | Value | Description |
|---|---|---|---|
| alpha | Number | 0 - 100 | Sets the transparency of each range in the color range. |
| code | Color | Hex Color Code | Hex code of the color range using which it will be filled. |
| label | Text | Any | This attribute determines the label for each numeric range. The label appears either on the gradient scale or on icon legends depending on the legend type used. 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. |
| maxValue | Number | Any | Specifies the upper limits of each numeric range. This attribute is mandatory in each `color` object for both gradient and icon legend. |
| minValue | Number | Any | Specifies the lower limits of each numeric range. This attribute is mandatory in each `color` object when icon legend is used. |
