I have a bar chart (a regular bar chart - not stacked) with two data series which shows the 7 days of the week. The two series are channels - let's just call them Channel 1 and Channel 2. What I need is when you click on the bar for a day/channel (say Monday - Channel 1) it will drill down to show you the top 5 shows for that day/channel. I already have which shows are the top 5 for each day/channel. I just can't figure out now to set it up in Xcelsius to do what I want. Any help would be appreciated!
