Treemap error

Hi everyone,

I have treemap where I wanted to show items, value and category of value.

I added item in group, value in value and category in details, which resulted in following error:

The groups in the primary axis and secondary axis overlap.

I used same approach for stacked column chart and it worked.

What can be wrong with it?

Also, I wanted to color by category, and I wasn't able to do it. In advanced control of data colors, I can't select category, only numeric values.

How I can color by category, so all items for category1 will have same color?

Regards,

Yerkhan
