I cannot tell from the demo, but is it possible ( and advisable ) to change the data as you drill down. For instance, see below for levels ( highest to lowest ):
- List of dates ( x-axis ) and numeric ratings ( y-axis, sort of percentages ). Actually, “dates” are the first date of the month ( for instance )
- List of, say, POs, for date they clicked on above ( x-axis has each date of period, and one or more POs ), and the number of shipments that were on time, or late, or early for each PO.
In the demo, the y-axis does not really change its function/data type. Even the x-access does not change its function/data type. But in my case, I would be changing the function or data type, with the corresponding labels. I am pretty sure this is ok, just seeing if people have better ideas or feedback on this approach.
