Hi, I'm currently trying to do something which I thought would be relatively straightforward, but it appears not.
Basically, I have a set of data that needs to be done logarithmically in a histogram, but appears the 'log=True' command in the pylab.hist() only refers to the y axis, rather than the logging the bins and x axis like i hoped. So, i know i can manually log the x axis (with pylab.semilogx()), but I'm tried finding out how to do log bins. However this seemed to not be possible, so I'm now trying to find out how to put my own desired bins into it. There should be an easy way to this.
For example, if I have the following code:
import pylab
a=[0.1,0.3,0.5,0.5,0.7,0.7,0.9]
pylab.figure()
pylab.hist(a,bins=4,range=(0,1))
pylab.show
it gives me a graph with a value of 1 between 0.0-0.25, 1 for 0.25-0.5, 4 for 0.5-0.75 and 1 for 0.75-1.0.
however, if I want to split just the dense bin up further, into 0.5-0.625 and 0.625-0.75 (which will give me a value of 2 in each), how can I make the histograph plot this?
How can i tell it my desired range of bins is from:
0.0-0.25
0.25-0.5
0.5-0.625
0.625-0.75
0.75-1.0?
thanks for your help
