I made my own custom modifier to act just like a rollover modifier, but allow keyboard input to move the rollover line between points. It was pretty easy to do and is working great, but there’s one final thing I cannot figure out how to achieve.

I want to display the the X-axis value tooltip below the vertical line just like the built-in RollOver modifier does. I was just going to manually render it, but it appears that you cannot render outside the chart modifier surface!

Is there any way to achieve this within SciChart or do I need to try to draw something completely on top of the entire SciChartSurface?

Hi there,

Thanks for your question. There is a special panel for this purpose, called ModifierAxisCanvas. It’s placed above an axis and inbuilt modifiers / annotations use it for their labels. You can access this panel by the ModifierAxisCanvas property on an axis.

Hope this helps!

Best regards,
