Easy way to plot X and Y in an array in C#

Question

Hello I am making a double buffer in C# and I need to find out a formula to plot the X and Y coordinates in my array. Currently I am using a loop to plot my X and Y but it takes along time to do it. (NOTE I CANNOT USE A MULTI DIMENSIONAL ARRAY!!!)

Can you show us what you have? Also define a long time? Is 1 second too long? What time are you looking for? — David Basarab, Jul 30 '11 at 20:17

int[] buffer = new int[width * height];

void Plot(int x, int y, int color)
{
    buffer[y* width + x] = color;
}

EDIT

To plot longer blocks you could use the Array.Copy functions

If that is still too slow you could fallback to unsafe code to fill the array

May be MathGL (GPL plotting library) may satisfy yours needs. It have no direct C# interface (in fact, it can be built by SWIG but I never try it). But, as I know, the C-functions can be called from C# easily.
