"3 axis" or "3 dimensional" (bar) charts are extremely useful to visualize complex data with (at least) 3 different data points.

We keep 3 levels of "problem" and "solution" classification data in our Zoho Desk tickets (for example main/sub/sub-sub problem fields for the "identified problem" class). Using "2 axis" or "2-dimensional" charts creates the need to drill down into the stacks to find out the 3. level of information whereas a nicely filtered 3 axis chart would easily visualize the same data without the need to drill down into the data.

Please consider adding these types of charts into Zoho Analytics.
