Scichart Display series markers on YAxis for each DataSerie C# WPF

Question

I'm creating a chart using scichart. I want to display some markers (eg. small Ellipses) on Yaxis for every Data Series depending on where the cursor is.

So far by using:

<s:SciChartSurface.ChartModifier>
   <s:ModifierGroup>
      <s:CursorModifier/>
   </s:ModifierGroup>
</s:SciChartSurface.ChartModifier>

I've obtained a cursor that marks the datapoints directly on charts.

Here is a picture of what I want to obtain (see the markers on Yaxis):

Interesting requirement! In SciChart the RolloverModifier exposes a collection of SeriesInfo - which are ViewModels used by all the cursor and legend types in SciChart.

You can bind anything to this data-source. The XySeriesInfo itself contains information about the series being viewed. For example, the SeriesName, the SeriesColor, the X,Y Values etc...

So, if you can bind to this collection of SeriesInfo as a data-source and create and add AxisMarkerAnnotations to the axis at the specified Y-Value then you can achieve what you want. The only problem is the Axis Markers will only be visible when the tooltips are visible.

For an idea of how to pull this together, consider creating your code to bind to SeriesInfo and add AxisMarkerAnnotations in a custom ChartModifier. (See the Custom ChartModifierBase API documentation for details on this powerful and flexible API.)
