I’m trying to save an Excel chart that has shapes (i.e. callouts) on it to an image using Chart.ToImage() but I am unable to get the shapes to save in the resulting image. I’ve also tried WorkSheet.ToImage and that doesn’t work either. Is there a way to get an image of a chart with shapes the user may have added to it? See my example code.
Well, I am afraid not all the shapes (including callouts) are supported when you take image of the chart using Chart.ToImage() method.
