For a bar chart, I am trying to achieve something similar to what is shown in the screenshot below (Green box with arrow pointing downwards). I was able to add the custom text (You are here) using CategoryTextAnnotation class, but could find a way to add a green background color to it.
Also wanted to know if there is way I can add the arrow too. Would really appreciate if anyone can give any pointers in achieving the greenbox with arrow. Thanks in advance!
