Hello Denis,

I'm with you here: this should be included, but the name is not well 
matching the features of the function.
Indeed, 'inset' is not at all what 'plot_plot' is offering.
I was also thinking about "non-linear-axis" or something like that, but 
I am not sure such a name will improve discoverability of the function.
But you are right: this is about having non-regular or non-linear axis.

nonlinear-plot ? non-regular-plot ? All this is not convincing for me...

By the way, we have developed some ugly hacks in the past to get 
'non-linear' or 'non-regular' colormaps for the same reason than Samuel.
The idea was to rescale the data to Sgrayplot such that one could map 
exact intermediate Z_values to some colors of existing or new colormap:

[0, 0.1, 1, 2, 100] -> [black, red, orange, yellow, white]

One of the key advantage is that you could be sure that a certain value 
(like z=0) was exactly corresponding to a certain color (like white) 
which is sometime necessary (for plotting  asymmetric waves or fields 
with a red-white-blue colormap for example).
