</style>Template
Any HTML elements can be added as a template in the data labels by using the labelTemplate property of cellSettings in the HeatMap.
The following examples show various data binding methods in the HeatMap using the labelTemplate property.
Array binding
By including ${value} in the template content, the value from the data source for the corresponding cell can be displayed in the HeatMap cell as data label template content. Additionally, the x-axis and y-axis label values can be displayed by including ${xLabel} and ${yLabel} in the template content.
Table
The following example demonstrates how to add a data label template for array table binding.

By including the desired field name in the template content, such as ${value}, the value from the data source for the corresponding cell can be displayed in the HeatMap cell as data label template content.
Table
The following example demonstrates how to add a data label template for JSON table binding.
