I have a situation in which I have a chart annotation that represents an event that happened. I want to add a marker that consists of several icons in the middle of it (see 1 and 2):

enter image description here

I tried the axismarkerannotation but it has a weird behavior of snapping its middle point and when it is paning out of range it disappears. I saw there is the possibility to place an annotation on the ModifierSurface but couldn't find an example.

I will fiddle around with this approach but perhaps someone has an solution for this? I want both markers to be visible and not when the potin in between 1 and 2 is out of sight both dissapear... Is treating both icons as seperate annotations the only viable solution?

  • Have you looked at Composite Annotation? https://www.scichart.com/documentation/win/current/webframe.html#The%20CompositeAnnotation%20Type.html It provides the ability to group annotations into one. Also setting `SciChartSurface.ClipOverlayAnnotations = false` means you can draw outside the main viewport and over the axis. – Dr. Andrew Burnett-Thompson Feb 22 '23 at 17:37
