I just upgraded to v2 of SciCharts (there was a bug before that didn’t allow me to do it earlier) and I got a question about the upgrade:

Before v2 I was using my own SeriesValueModifier but now I switched to the included one in the library. My question is, how do I customize the font & background color of the indicator on the Y-Axis?

Look forward to hearing from you.

Hi Diego,

To customize look of SeriesValueModifier, you could set any of the BorderBrush, Background, Foreground properties. Also you can define a Style and apply it to AxisMarkerStyle property:

                <Style BasedOn="{StaticResource AxisMarkerAnnotationStyle}" TargetType="a:AxisMarkerAnnotation">
                    <!--  Assumes data context is the RenderableSeries  -->
                    <Setter Property="BorderBrush" Value="{Binding Background, RelativeSource={RelativeSource Self}}" />
                    <Setter Property="Background" Value="{Binding SeriesColor, Converter={StaticResource ColorToBrushConverter}}" />
                    <Setter Property="YAxisId" Value="{Binding YAxisId}" />
                    <Setter Property="IsHidden" Value="{Binding Path=(c:SeriesValueModifier.IsSeriesValueModifierEnabled), Converter={StaticResource InvertBooleanConverter}}" />

Regarding the second issue, we logged it and will try to investigate. It would be very helpful if you could reproduce it in small project and post/send it (if it is possible).

And about the last issue, could you post here/send us some screenshots showing the desired behavior? It will clarify the request a bit so we will be able to give more precise answer.

Best regards,

    Hi Yuriy!Thanks for the reply, I was able to modify SeriesValueModifier with your suggestion.Regarding the second question, I will try to put together a small project that reproduces the error during the weekend, but like I told you in my first post, the application doesn't crash, it just logs the exception to the console and continues (I don't have a try and catch, so the logging must come from your code).Finally, regarding the behavior that I want from RollOverModifier, I've attached 3 files:- ChartWindow.png: shows how my charts look at the moment. I have the price & volume charts synchronized including the RollOverModifier, but all the tooltips are separated. What I want is to merge all the tooltips into one. Basically include the time from the X-Axis and volume on the same tooltip. Also, as soon as I overwrote the AxisLabelTemplate, the label on the Y-Axis appeared, so do I get rid of it?- ChartWindow.xaml (zip): my current implementation of ChartWindow class.- XStudy.png: shows the behavior I want to achieve, basically one tooltip the merges the info from the price and volume charts.I really appreciate the help you guys give, look forward to hearing from you.Best,Diego
