Thanks for the quick reply David.
I was thinking more something like this:
Assume we have, x,y and data.
if we use
cgContour, data, x,y
we will get a plot with axis having the values of x,y
In cgImage, i was thinking like
cgImage, data, /axis, xabscissa=x, yabscissa=y
That would produce a similar result.
If somebody wants to plot many images with values on axis, this would be much faster and easier than
cgImage, data, /axis, xr=[min(x),max(x)], yr=[min(y),max(y)]
Cheers,
Petros
