怎样用C#画一个坐标轴
我自己画了两条线作为坐标轴，想再加入一些刻度并标上值，请问要如何写代码？谢谢
Graphics g = this.pictureBox1.CreateGraphics();
g.DrawLine(Pens.Blue, new Point(0, 100), new Point(90, 100));
g.DrawLine(Pens.Blue, new Point(0, 0), new Point(0, 100));

[解决办法]
要看你想用什么来表示刻度了，用直线，点都可以啊，比如要将X轴分n等分，用直线画就是：

for(int i=1;i<=n;i++){
  g.DrawLine(Pens.Red, new Point(i*100/n, 0), new Point(i*100/n, 2));
}

Graphics g = this.pictureBox1.CreateGraphics();
g.DrawLine(Pens.Blue, new Point(0, 100), new Point(90, 100));
g.DrawLine(Pens.Blue, new Point(0, 0), new Point(0, 100));

int n = 10;
for (int i = 1; i <= n; i++)
{
    g.DrawLine(Pens.Red, new Point(i * 100 / n, 98), new Point(i * 100 / n, 100));
    g.DrawString(i.ToString(), SystemFonts.DefaultFont, new SolidBrush(Color.Red), new Point(i * 100 / n, 100));

    g.DrawLine(Pens.Red, new Point(0, i * 100 / n), new Point(2, i * 100 / n));
    g.DrawString(i.ToString(), SystemFonts.DefaultFont, new SolidBrush(Color.Red), new Point(2, i * 100 / n));
}
