How to create coordinates on the form?

Question

I want to create a form, which has two lines on it just like the two coordinates x-axis and y-axis. And then I want to add points on these coordinates. e.g.

• on this point(2,3) I want to add a point a
• on the point (-4,5) another point b
• on the point (-5,-7) another point c
• on the point (4,-6) another point d

How can I do this? Here are the two lines, which I have drawn:

e.Graphics.DrawLine(Pens.Black, 190, 210, 350, 210)
e.Graphics.DrawLine(Pens.Black, 330, 90, 330, 300)

Answer 1

Since you already have your lines, use this for your points:

e.Graphics.FillEllipsis(Brushes.Black, new Rectangle(x,y,width,height));

x,y is the coordinate where you want the circle to be. Width height is obviously the size of your circle
