I am trying to use a BoxAnnotation to put an image on my graph. I am using BelowChart AnnotationCanvas so I can have the graph on top of the image. However, doing so also puts the grid lines on top of the annotation as well. Is there a way to keep the annotation below the chart but still keep it above the grid lines?
Unfortunately there is not. A BoxAnnotation has AnnotationCanvas values of AboveChart, BelowChart.
The AboveChart places the box annotation on top of the main RenderSurface, the BelowChart places below RenderSurface.
Both the series and gridlines are drawn to the RenderSurface I’m afraid, which is why the BoxAnnotation is below the gridlines.
Sorry I can’t be more help,
