I have a table contain huge plot data. The plots are grouped by plotID.
I'd like to be able to dynamically add and remove series into one DBchart to compare each plots.
My solution is to create queries for each plots then create series based on that query.
I think there's much better way than that, could anyone tell me how?

Hi.

You could use one of the cross tab features included in TeeChart (check the demo to see how it works), but I think your solution is also quite good. Well, you could pre-create specific number of series and then display/hide them by setting the TChartSeries.Active property, but freeing and re-adding series as new query is created is also good.
