[SOLVED] How to insert a series in a chart during runtime? lazarus / 55-TAChart ---------------------------------------------------------------------- CM630 · 2013-05-22 06:21 I have several series in a chart, they are of different types. I need to insert a series. There is a method .AddSeries, but there is no insert. Series have an .index property but haw am I to swap the indexes of two series? I did  Chart1.Series[2].Index:=X; but it occurs that .Index is now writeable and Chart1.Series[2].Index:=X; did nothing. ---------------------------------------------------------------------- wp · 2013-05-22 08:09 "AddSeries" first, then set the Index of the new series to the position where you want it to be.
