When using RollOverModifer, is there a way of showing just one pop-up for two synced charts? I have a candlestick chart on the upper part of the window and a bar chart in the bottom, so what I want is a synced RollOverModifier that displays the price & volume information together in just one pop-up. Plus, is there a way of hiding the Rollover date pop-up for the X-Axis of the bottom chart (The upper chart Rollover is already displaying the date, so the bottom one is redundant).

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

Hi Diego,

Sorry for the delay in answering! Regarding the axis label issue, you should use the AxisInfoTemplateSelector class or bind a visibility of the label to the AxisInfo.IsXAxis property. Here is the default data template for RolloverModifier:

    <DataTemplate x:Key="EmptyDataTemplate" DataType="r:AxisInfo" />

    <!--  Template for the RolloverModifier AxisLabel to display single AxisInfo (result of hit test)  -->
    <ControlTemplate x:Key="RolloverAxisLabelTemplate" TargetType="r:TemplatableControl">
        <s:AxisInfoTemplateSelector Content="{Binding}"
                                    XAxisDataTemplate="{StaticResource AxisLabelTemplate}"
                                    YAxisDataTemplate="{StaticResource EmptyDataTemplate}" />
    </ControlTemplate>

Regarding the second issue(merge tooltips) it needs writing code a bit. You could have MasterRolloverModifier from this thread and merge SeriesData.SeriesInfo into a single ChartDataObject object inside. And use this modifier for the main chart.

Please, let us know if you need any clarification or assistance!

Best regards,
Yuriy
