Choose distinct and ordered colours for multiple 2D line

yamid

Hi
I am writing a program that can draw many 2D lines (for example 10 line plots) using C#.
I want to use distinct and ordered colours for each line. I want to define a fixed order of colours, where the first 2D line graph be always colour1(like blue), the second graph to be of colour2 (for example red),... . Can you please help how to do this?
1. define an array of colours[]
2. Use colour[0] for line 1, colour[1] for line 2,....

Thanks.

Hi,
Try like this

protected override void OnPaint(PaintEventArgs e)
{
string[] colors = new string[] { "red", "blue", "white", "green", "orange", "black" };
int x = 10;
for (int i = 0; i < colors.Length; i++)
{
Pen pen = new Pen(Color.FromName(colors[i]));
e.Graphics.DrawLine(pen, x, 10, x, 100);
x = x + 10;
}
base.OnPaint(e);
}

Regards,
Iftikar
