SharpPlot.DrawPieChart Method

Constructs a piechart from an array of data values and optional segment explosions.

Example

sp.SetMargins(0);
sp.PieChartStyle = PieChartStyles.ValueTags;
sp.ValueTagStyle = ValueTagStyles.Inside;
sp.SetValueFont("Arial",18,FontStyle.Bold,Color.White);
data = new int[] {31,23,16,8};
expl = new int[] {0,0,25,0};
sp.DrawPieChart(data,expl);

The short tutorial shows a few of the possibilities and some sample code.

Overloads

• public void DrawPieChart(int[] data);
• public void DrawPieChart(double[] data);
• public void DrawPieChart(int[] data,int[] explode);
• public void DrawPieChart(double[] data,int[] explode);

Description

The Piechart is typically used to show how some total value is divided up, for example sales in two or more regions. It works best when there are only a few values, and they should be ranked in numerical order to facilitate comparison of the sctor sizes. Pies are often labelled with the actual values in the sectors, and one or more sectors may be ‘exploded’ to emphasise certain values.

If there are more than 5 or 6 values, and it is important for the user to be able to compare values accurately, the simple Barchart is almost always a better format.
