Series Groups and Extra Legend

[ulibru]

Hi,

I like to use two groups of series.
Group A: curves 1, 2, 3, ...
Group B: curves a, b, c, ...

Now I want to display the curves of group A in the standard legend with checkboxes
And the curves of group B in an extra legend. Also with checkboxes.

How to get the desired two legends showing each the individual group curves with checkboxes ? If this is not possible then how to show one legend with a dividing line between the two group curves?

Hi Uli,

I'm afraid there is no way to do it "automatically" right now. However, I can think on three alternatives:

1. Use two TCustomLegendTool, adding checkboxes for each series manually. Take a look at the example at "What's New ?\Welcome !\New Chart Tools\Custom Legend" int he features demo program to see how to use this tool.

2. Create you own custom legend class. It could have an array of series and create as many checkboxes as items in that array.

3. Improve the TExtraLegendTool in two aspects. You can do it yourself if you have the source code, or you can wait until we implement it in a further release:
3.a. Make it independent of the default Legend. You can hide any series to be shown in the default legend setting ShowInLegend=false, but this series won't be shown in the TExtraLegendTool either (TV52016085).
3.b. Make its checkboxes to respond to to the mouse actions (TV52016084).
