Hi Koen, I've tried to recreate the issue you mentioned using a raster dataset I had symbolized using stretched renderer set to calculate statistics using the current display extent. Please let me know if this is does not relate to your case. If it doesn't and you could please provide more details that would be great. I was able to see the problem. I would change extents and while the min and max values would be recalculated, the legend would not update. This is a bug that we will look at. However, in the meantime I was able to force the legend to update by using 'arcpy.RefreshActiveView()'. I hope that helps. Thanks for bringing this issue to our attention. Regards, Sam
