help with scatter plot-like data [message #84885]

Hi

I'm really out of my depth here with my minimal knowledge on IDL. Basically I'd like to make a color-coded 2D scatter plot, but I'm not sure how to do it.

Here's the thing. I already have values for my x and y axis and I already know that the positions of the scattered points for my z-axis are just the sqrt(x^2+y^2). But I'm not sure how to plot them in 2D.

I tried a dummy array
dummy=fltarr(3,n_elements(dataz))
dummy[0,*]=dataz
dummy[1,*]=xaxis
dummy[2,*]=yaxis

but then I have no idea how to use the plot command to make the scatter plot.

Any help will be very welcome!

Cheers
