I have a tree map that is the number of events from a particular deptartment. There are about 100 different types of events so I have put a category Map onto it , see below for example
I have a tree map based on Event , but there is just loads of different Events, so I have written a tree map basedon the categories.
But I would like there to be a drill down so if in the catergories Tree map, if I select Documentation, I can then see how many Confos, Statements, Certificates etc !!
Can anyone help me with this please ?
