Hallo All,
I still could not figure out the above. In brief, I have 2 menu actions, for ex. Total Traffic & Network Layer- please see attached figure. The first one will trigger plotData() that draws a plot (Bandwidth Graph), and the second one will trigger a pie chart. The problem is that the pie chart is always shown behind the plot.

As suggested by @ChrisW67 I tried to implement but still no luck.
