Hi
Phil,
When
a percentage value is set to the "Height" property of the
TreeMap component, it renders based on the size of its parent HTML element. We
suspect that the div element containing the TreeMap component in your
application does not have the proper height specified, causing it to render
with the default value of "450px".
However,
when we set the "Height" and "Width"
properties of the TreeMap to "100%" and specify its parent div
element as "600px", the component renders properly with the size
provided by the parent div element. You can find the sample that demonstrates
the same below.
