To manage the size of the control, you need to set the Height and the Width of the ChartServerControl.
ChartServerControl1.Height = 500;
ChartServerControl1.Width = 500;
To manage the size of the chart itself, you can play with the Margins of the Chart.
m_Chart.Margins = new RectangleF( 0, 0, 100, 100 );
