Hello... I'd like to create a line chart similar to the one below... except on the lower line, it shouldn't drop to the x-axis if the value doesn't exist (currently being set to dbnull)... I just want it to plot the points it has. Is there any way to do this?
Currently, I'm building a datatable with the columns being (Name, 4/1/2010, 4/2/2010, ...) and the rows being each line... so the datatable for the chart below consists of two rows and 13 columns (1st being Name and then 12 dates).
Any ideas? I want to be able to chart date-based collections where each name may not have the exact same date list.
Thanks

Thanks! Once you showed me DontPlot, I looked at the other enums and saw InterpolateSimple, which is closer to what I'm looking for...
Thanks again!
If you do a search in the forums for NullHandling you will find more info and examples. Let me know how that works!

If your chart is called UltraChart1, try setting:
UltraChart1.LineChart.NullHandling = UltraChart.Shared.Styles.NullHandling.DontPlot;
