Well i caused much confusion and this wasn't my intent.
I don't need strch of pixel or things like that. Forget about the non-uniform grid.
I was talking about non uniform vectors in the sense of
x=findgen(10)
cgcontour, data, x^2, alog10(x)
Nothing more than that. Sorry for the trouble i caused you, because clearly i couldn't get you to understand what i was saying, as i was saying it wrong!
I use images from solar observatories, where every data set comes with a solar_x and solar_y vector.
In the last years I've made my own wrapper programs of tv about plotting imaging, or use astrolib routines, but the more i use coyote library the more i want to use it fully, without making wrapper for it. This is why i discussed about intuitive and simple things.
Now about the previous discussion with the cgImage, in general, i think that an axis goes with a vector that defines it, so this is what i was referring as intuitive.
Besides that cgImage discussion, by no means I did not mean to offend you or to make you upset by this conversation.
After all, if you weren't involved with idl graphics, everybody dealing with IDL would have to curse daily 20 times more the people who designed idl graphics in the first place, and feel 20 times more miserable trying to do the simplest thing.
I personally cannot work without your work, which i admire greatly. And that is why the more i use it, the more people i try to persuade to use it.
That is the reason i post about bugs i find etc. I like it see it becoming even better! It feels like posting in opensource project forums!
I dont know if i sounded ironic telling you "From your amazing work concerning usability and simplicity in idl graphics, I assume that a fan of simplicity such as yourself would like to get new ideas on how to improve the usability of his software!"
I honestly believe every word of it, and i think the above as a compliment.
Regards,
Petros
