[Solved] LegendTitle and dynamic series?

[Per]

Hi!

Is it possible to bind the LegendTitle property in a CategoricalSeriesDescriptor?
(I want to create a chart with dynamic series and a RadLegendControl)

Hello Per,

Unfortunately currently RadChart does not provide legend support for scenarios with dynamic series generated via ChartSeriesProvider. I will forward your feedback to our developers for further consideration when planning the product backlog for the next release and you can also vote for this feature in our public ideas and feedback portal here (the higher the demand, the higher the priority).

Hi again!

Is there a workaround for this? Can I create my own legend and extract the colors used in the chart?
If so, do you have any sample that can do this? :)

Hi Per,

Thank you for your interest.

Yes, you can add LegendItems manually like this:

<Primitives:RadLegendControl x:Name="Legend1">
    <Primitives:RadLegendControl.LegendItems>
    <Primitives:LegendItem
        Title="FirstSeries" Fill="Blue" Stroke="Blue"/>
    </Primitives:RadLegendControl.LegendItems>
</Primitives:RadLegendControl>

Also, you can extract the color from chart palette like this:

// Chart1 is the name of RadCartesianChart instance.
LegendItem item = new LegendItem();
item.Title = "FirstSeries";
item.Fill = Chart1.Palette.FillEntries.Brushes[0];
item.Stroke = Chart1.Palette.StrokeEntries.Brushes[0];

Legend1.LegendItems.Add(item);

I hope this is useful.

Hi Giuseppe,

I'm not sure if it'll help move this feature up the list or not but I would really like this feature as well.

Thanks,
