I want to draw these point in a panel, but how you can see tere are some points with negative values. How can i move the origin point (0,0), to (200, 200). I want to make all points visible in panel.

Solution

  • You could calculate the center of the panel you're drawing into:

    float centerX = this.ClientSize.Width / 2.0f;
float centerY = this.ClientSize.Height / 2.0f;

    And then draw relative to the center:

    graphics.DrawLine(centerX + x, centerY + Y, centerX + x, centerY + y);

    All the points would "gather" around the center.
