[Matplotlib-users] A request for a Matplotlib extension to hist

[Virgil S. <vs...@it...>]

I have some Python (2.7.9) code that processes some rather large data sets to 
determine the curvatures along 2D curves. One feature of these data that I like 
to look at is the distribution of the curvatures. I use NumPy to to determine 
histograms for each set, and save the histogram parameters returned from 
numpy.histogram in a file.

I would like to use Matplotlib to plot histograms *from the parameters returned 
in NumPy* and stored in a file --- why? Because the size of my data sets does 
not allow for the use of the histogram plot function in Matplotlib (1.4.3); 
i.e., it needs the data sets to calculate the histogram, before doing the plot. 
I would like to have a histogram plot function in Matplotlib that could bypass 
the actual calculation of the bin counts and edges from the data, and use values 
of these found /a priori/. Of course, an obvious question is -- Why not write 
code to plot the rectangles yourself? Yes, I could do this; but, why not extend 
the Matplotlib histogram class to allow for this option? If I better understood 
Matplotlib, I would try this myself. Maybe it is possible to get this into the 
next planned release (1.5).:-)

If this request is inappropriate for this list, then please accept my apology 
and direct me to where I should send this request.

Best regards.
