Each item in the data source is required to have
label
and
value
fields. To create nested elements, you need to set the
parent
field to point to the
label
of another item. The
data
field enables you to store additional data associated to each treemap sector. By setting the
color
field you can determine the sector's background color.
In order to populate the jqxTreeMap through jqxDataAdapter, you need to set the "source" property of jqxTreeMap to point to an instance of jqxDataAdapter. The
label
and
value
fields of each treemap sector are determined by the
displayMember
and
valueMember
properties.
