推荐答案

例如考虑Microsoft图表：http://msdn.microsoft.com/en-us/library/dd456632.aspx [ ^ ]（适用于.NET v.4.0-4.5）。



对于v.3.5，请下载 http ：//www.microsoft.com/en-us/download/details.aspx？id = 14422 [ ^ ]。

For example consider Microsoft Charts: http://msdn.microsoft.com/en-us/library/dd456632.aspx[^] (for .NET v.4.0-4.5).

For v.3.5, download http://www.microsoft.com/en-us/download/details.aspx?id=14422[^].

试试这个：

Try this:

public void DrawPieChartOnForm()
{
    //100% C volume, 60% free space on it
    int[] myPiePercent = { 40, 60 };
    Color[] myPieColors = { Color.Red, Color.Black };

    using (Graphics myPieGraphic = this.CreateGraphics())
    {
        //Give Location Which Will Display Chart At That Location.
        Point myPieLocation = new Point(10, 10);

        //Set Here Size Of The Chart…
        Size myPieSize = new Size(150, 150);

        //Call Function Which Will Draw Pie of Values.
        DrawPieChart(myPiePercent, myPieColors, myPieGraphic, myPieLocation, myPieSize);
    }
}


// Draws a pie chart.
public void DrawPieChart(int[] myPiePerecents, Color[] myPieColors, Graphics myPieGraphic, Point myPieLocation, Size myPieSize)
{
    int PiePercentTotal = 0;
    for (int PiePercents = 0; PiePercents < myPiePerecents.Length; PiePercents++)
    {
        using (SolidBrush brush = new SolidBrush(myPieColors[PiePercents]))
        {

            //Here it Will Convert Each Value Into 360, So Total Into 360 & Then It Will Draw A Full Pie Chart.
            myPieGraphic.FillPie(brush, new Rectangle(new Point(10, 10), myPieSize), Convert.ToSingle(PiePercentTotal * 360 / 100), Convert.ToSingle(myPiePerecents[PiePercents] * 360 / 100));
        }

        PiePercentTotal += myPiePerecents[PiePercents];
    }
    return;
}
