Hi all,
Thanks to ibespalov for the great help days before. What I want to do is to draw a pie chart on the map according to the given longitude and latitude. After a little bit of research, I found that infosymbol might be the answer to my problem. However, when I draw the chart, there's always a square background frame and the legend overlap with the pie chart. Can anyone teach me how to solve it? Thanks in advance!
