how I can maximize the piechart it self not all its frame ??
Sorry - but your question isn't very clear, can you describe what you are trying to achieve in a bit more detail?
Mahmoudhelaly, have you tried adjusting the pieSeries.outerRadius? That controls the radius of an individual pie chart series or ring of a donut chart. Does that cover what you're looking for?
