plot colored ellipses [message #79663]

Hi,

I made a simple 2D scatter plot from a square array "matrix", using
plot, matrix,psym=3. I would like to make nice-looking images by:
- plotting ellipses instead of points (but centered on the points
coordinates)
- orientate these ellipses as I want
- use different colors for them
- apply a color gradient to each ellipse, i.e bright red in the center
and light at the edge
- etc

Could you please tell me where I should start to make such image?
because I am not very used to make pretty images in IDL... :)

thanks!
