Working with data

Heat map visualizes the JSON data and two-dimensional array data. Using the data adaptor support, data can be bound to the heat map.

Data adaptor

Heat map supports the following types of data binding with the adaptor support.

  • Array

    • Table Binding
    • Cell Binding
  • JSON data

    • Table Binding
    • Cell Binding

Array - table binding

This data type is a collection of one dimensional array objects, at which each inner array contains data points for an X-axis data label. This is the default data binding type for heat map. You can also directly bind the array object to the dataSource property.

JSON data - table binding

In JSON table data binding, each JSON object contains an X-axis data point as row header and all the corresponding Y-axis data values. You can bind the JSON table data to the heat map using the data property in dataSource. To achieve this, you should enable the isJsonData property and define the adaptorType property as Table. The xDataMapping property is used to map the row header in JSON data.

JSON data - Cell binding

In JSON cell data binding, each JSON object consists a value for each cell along with a mapping value for row and column. You can bind the JSON cell data having information for each cell to the heat map using the data property in dataSource. To achieve this, you should define the adaptorType property as Cell. and enable the isJsonData property. Now, map the fields of data by using the valueMapping, xDataMapping and yDataMapping properties.

Empty points

The data points that use the null or "" or undefined as value are considered as empty points. Empty data points are ignored and not displayed in the heat map, and these points are rendered with default palette. You can customize the empty data point color value using the emptyPointColor property.

Binding nested JSON data

In complex data binding, you can bind the nested JSON data to the data points in the heat map. The nested data can be mapped using the xDataMapping, yDataMapping, valueMapping and bubbleDataMapping properties as string value concatenated by a dot.
