Data label in JavaScript Treemap control
Data Labels are used to identify the name of items or groups in the TreeMap component. Data Labels will be shown by specifying the data source properties in the labelPath of the leafItemSettings.
Format
Customize the labels for each item using the labelFormat property in the leafItemSettings.
Template
The template supports customizing labels of each leaf node using the labelTemplate property. It uses Essential® JS2 template engine to render elements and the position of templates can be customize using the templatePosition property.
InterSectAction
When the label size in each item exceeds the actual size, use the interSectAction property in the leafItemSettings to customise the labels.
