Hello,

I have a chart currently working. (See attached Chart_Current.png for what I have now)

I’d like to add concentric color-filled zones to the chart, to indicate when the already existing line series enters and exits particular zones of interest. My zones are elliptical, and I need to be able to define them as such (so I do not think the “Bubble” stuff will work). I need to color in the space inside my zones, with some opacity, such that the original renderable series can still be seen. (See attached Chart_Goal.png for a crude MS Paint drawing of what I am trying to achieve.)

I have explored the WPF Examples App and seen several promising chart / series types, but I am still not sure how to proceed. It seems the HeatMap stuff will probably be useful, but I am not sure how to define my HeatMap zones elliptically.

Any tips on how to proceed would be greatly appreciated. I am just trying to get pointed in the right direction.

Thank you!

Kurt

Resizing Custom Annotations - Custom sized ellipses

WPF Ellipse Box Annotation Re-templating

To whom this may concern:

I’ve been reading through the following posts:

https://www.scichart.com/questions/question/how-to-draw-oval-circle-annotation
https://www.scichart.com/questions/question/resizing-a-custom-annotation

Unfortunately, I’m no closer to generating a re-sizable oval ellipse: mainly because techman234’s response is all gibberish and I’ve no clue how to re-template a box annotation. I’ve observed your “create annotations dynamically” and “composite annotations.”

Could you give a more thorough tutorial on this? I would like to design a resizable custom annotation like I would a regular custom annotation without the AnchorPointAnnotations limitations.

Thanks kindly!

EDIT: Found a resource but still need help

https://www.scichart.com/documentation/v4.x/webframe.html#The%20CustomAnnotation%20Type.html

So after doing some deeper digging, I came across this link that sufficiently explains how to make a box template. I was able to make an ellipse but the heights and widths are fixed. I can re-size the outer limits of the invisible “box” but the ellipse itself remains the same size.

I would like to be able to re-size and re-shape the ellipse along with the box. I would also, if possible, have a mechanism to rotate the ellipse to a certain angle.

Can you please advise?

Thanks!
