Add Support to Create Fragments with Positive and Negative Data for Stacked Series
With a stacked area series chart, when values in the first series go negative and then positive again, the first series is drawn behind the second rather than stacked. When the series are opaque, this issue become more egregious because the first data series is completely obscured.
Unfortunately, I have been told by the Infragistics development support team that adding this functionality is currently not possible given how the chart's framework was designed. Attached is a screenshot demonstrating this issue.
I would expect the stacked series chart to display normally, so where the violet colored series is showing on top of the other series, it should show behind and only in front of the colors that have a larger value than it. Just like the other colored series in the chart.
I would add a screen shot, but I do not see a way that I can add an attachment to this comment, or edit my original post to include another attachment. However, if you could imagine the stacked chart without the violet appearing over the other colors, then that is what I would expect.
For your convenience, you can reference my conversations about this problem with Infragistics support in case CAS-140570-G7D9H6 and development issue 176766.
Do you have any examples or sketches that show what you would expect the chart to do in your situation?
