To whom this may concern:

I have a Custom Renderable Series that I use to draws a polygon around the points on a scatter plot.

protected override void Draw(IRenderContext2D renderContext, IRenderPassData renderPassData)
    base.Draw(renderContext, renderPassData);

    var blobShellPoints = getBlobShellPoints();

    using (var polyPen = renderContext.CreateBrush(Colors.DodgerBlue, 0.3))
        var startCoordinates = getCoordinatesFor(blobShellPoints[0].X, blobShellPoints[0].Y);

        using (var blobDrawingContext = renderContext.BeginPolygon(polyPen, startCoordinates.X, startCoordinates.Y))
            foreach (var point in blobShellPoints)
                var pointCoords = getCoordinatesFor(point.X, point.Y);

                blobDrawingContext.MoveTo(pointCoords.X, pointCoords.Y);

I would like to know if there is some way to show a tooltip when the mouse hovers over the said drawn polygon. I don’t see any ability to do this after I finish creating the polygon or before the end of the encapsulated polyPen disposable. It should look something like the attached image.

Can you please advise? Thank you kindly for your response!

P.S. I realize some of this code may be obsolete since I’m using SciChart 5. If this is only possible in 6+ then that’s understandable.

I have followed the 50 EEG example in creating a group of graphs which is populated using a listbox and a data template. The graphs are created and populated correctly. The issue arises when creating graph modifiers (eg Rollover, Zoom). Is there an issue with selecting these graphs or adding modifiers.

Thank You
