Hello Michal,

My team and I have done an initial review of this forum thread, and I would like to get some more information regarding your scenario to see if we can figure out why the markers are not showing for you in your legend. Can you please provide some information on the following?

1. What series type(s) are you using for your different legend entries?

2. Are you creating a MarkerTemplate for your series? If so, can you please provide this template?

3. It looks like your legend is in a popup of sorts. As a test, does the legend work normally if it is placed on the page with the chart?

4. Do you have an isolated sample project that you can share that demonstrates the behavior you are seeing?

Please let me know if you have any other questions or concerns on this matter.

Hello Michal and Dean,

My apologies, when I originally answered this thread, I missed a property that was added semi-recently. I would recommend setting the LegendItemBadgeMode property of your series that are plotted in the chart to “MatchSeries.” This should allow the marker to reappear.

Please let me know if you have any other questions or concerns on this matter.

Hi Dean, that worked. Thanks!

Hi Michal,

Just set the LegendItemBadgeMode property in the series to 'MatchSeries'.

Then it will behave like before.

Hope this can help you.

Hi Andrew, sorry for late response, here are my answers:

1. Scatter Series

2. Yes, code:

DataTemplate CreateMarkerTemplate(ISeriesViewModel seriesVm)
{
    var seriesLabelFactory = new FrameworkElementFactory(typeof(TextBlock));
 
    var titleBinding = CreateBinding(seriesVm, nameof(seriesVm.Title));
    seriesLabelFactory.SetBinding(TextBlock.TextProperty, titleBinding);
 
    var foregroundBinding = CreateBinding(seriesVm.Style, nameof(seriesVm.Style.Colour));
    foregroundBinding.Converter = _seriesColourConverter;
    seriesLabelFactory.SetBinding(TextBlock.ForegroundProperty, foregroundBinding);
 
    seriesLabelFactory.SetValue(TextBlock.BackgroundProperty, _labelBackgroundBrush);
 
    return new DataTemplate { VisualTree = seriesLabelFactory };
}
3. not working. 
4. Unfortunately not. 

code here:
