Configure Position of Pie Charts
If you have more than one pie chart to display, you can set the grid parameter, and also the position of each pie.
For example, in the snippet below, we set the
grid to 2 by 2 and also pass a set of row and column index positions. Each row/column position index corresponds to each pie.1
