I have three charts based on the “Synchronize Multi Chart Mouse” example.
There are three modifiers in the ModifierGroup as follows:

     <SciChart:ModifierGroup mouse:MouseManager.MouseEventGroup="cellTimeModifierGroup">
                                    <SciChart:RolloverModifier/>
                                    <SciChart:MouseWheelZoomModifier ReceiveHandledEvents="True" XyDirection="XDirection" />
                                    <SciChart:ZoomExtentsModifier/>
    </SciChart:ModifierGroup>

I want to use MouseWheelZoomModifier and ZoomExtentsModifier to sync the three charts, but as for RolloverModifier, I want it to be only shown on the chart that has focus.
How do I implement that?

Hi Xifeng,

It’s not something we support out of the box, but there is a documented workaround. Please check out this related post titled Sharing Mouse Events one-way.

Best regards,
Andrew

    Good idea. It solved my issue, thanks. There is a method called ' ReceiveHandledEvents ' in RollerModifier. What is the useage of this property? Do you have any plan to change it like: In same MouseEventGroup When this is true, it is triggered by another modifier. When this is false, it is not triggered by another modifier.

    Hi Xifeng, you can find all the answers about what ReceiveHandledEvents does in our KB article How to add Mouse Interaction to a SciChartSurface. At the moment we have no plans to change this area of the API. Best regards, Andrew
