Dear all,
as there was no disagreeing feedback ;-) I continued my work on the
hist() method. I just committed a patch with some major re-writing of
the hist() method to the trunk. I personally think it is very useful.
hist() now
- supports 2D input data (i.e. multiple data, but not yet list of
arrays with different length; is a TODO)
- supports "stacked" histograms for multiple data
- the 'edge' alignment has been changed to align a bar in the center
between two edges rather than on the left edge of a bin. This seems
be more convenient (to me) and plots are easier to interpret
- the width keyword is Deprecated, and the new keyword rwidth is
introduced to give the *relative width* of a bar rather than an
absolute value (i.e. rwidth = 0.8 means the width of the bar is 80%
of the width of the bin), this also works for *unequally* spaced
bins
- I added an example histogram_demo_extended.py to show how the new
features work / look -- I like it ;-)
These changes also mean some minor API breakings (alignment='edge';
width deprecated), but as hist() in the trunk has switched to future
numpy.histogram(), users have to check there code anyway.
I am, however, not very happy with the align keywords. I have more or
less left this as is, but don't find them very logical: 'center' means
centered on the left bin-edge, and 'edge' means centered on the center
of the bin :-(
