Click Actions on Heatmatrix Charts
Heatmatrix charts have the unique ability to allow you to activate a click action on a row that doesn't exist in the source data. For example, depending on the application, a combination of a dimension value and category value can exist in other sources but not in the source marker. In this case, the combination appears as blank cells in the heatmatrix chart. Therefore, when you add a click action to a heatmatrix chart, DI recommends that you include a conditional value as a requirement to activate the click action.
