If you want to be able to apply a dashboard filter by clicking on a chart, follow these steps:
1. Create an input control, that will highlight a target chart A (set the target to chart A and the Action = Highlight). You can make that input control invisible, if you like, by setting its location to the Control Bar of the dashboard.
This will not only create a listbox that will highlight an item in the chart, but will also has the effect of setting the listbox value by clicking on that chart.
2. Now add chart B as another target to that input control, then set that target to filter.
Now, when you click on a column in chart A, it will filter chart B by that column.
