Making A Graphic Pie Chart In C#
提问by Cistoran
I'm trying to write a Windows Application that shows a pie chart with seven unequal slices (25%, 20%, 18%, 17%, 10%, 10%, 10%) all of them will be colored differently.
我正在尝试编写一个 Windows 应用程序，该应用程序显示一个饼图，其中包含七个不相等的切片（25%、20%、18%、17%、10%、10%、10%），所有切片的颜色都不同。
So far I have made Pens and Brushes with colors attached and drawn a circle.
到目前为止，我已经制作了带有颜色的钢笔和画笔并画了一个圆圈。
This is what I have so far
这是我到目前为止
private void Form1_Paint(object sender, PaintEventArgs e)
{
this.BackColor = Color.White;
this.Text = "Pie Chart";
this.Width = 350;
this.Height = 350;
Pen black = new Pen(Color.Black);
Pen blue = new Pen(Color.Blue);
Pen green = new Pen(Color.Green);
Pen red = new Pen(Color.Red);
Pen orange = new Pen(Color.Orange);
Pen pink = new Pen(Color.Pink);
Pen purple = new Pen(Color.Purple);
Pen magenta = new Pen(Color.Purple);
Brush brBlue = blue.Brush;
Brush brGreen = green.Brush;
Brush brRed = red.Brush;
Brush brOrange = orange.Brush;
Brush brPink = pink.Brush;
Brush brPurple = purple.Brush;
Brush brMagenta = magenta.Brush;
Graphics g = e.Graphics;
g.DrawEllipse(black, 20, 10, 300, 300);
}
My question to you is. What would be the easiest way to draw the wedges of the pie?

This isn't a direct answer to you question, but why aren't you using the Microsoft chart controls?
这不是对您问题的直接回答，但您为什么不使用Microsoft 图表控件？
