To determine this threshold, you can plot the distribution in the number of reads by doing the histogram in a python terminal with histo_r.py: from pylab import * from histo_r import * MATRICE=loadtxt("chr3_RAW.txt"); histo_r(MATRICE.sum(axis=0),100); The function histo_r(V,N)...

Now that we know who the biggest customers are and how they purchase products, we might want to look at purchase patterns in more detail. Let’s take another look at the data and try to see how large the individual purchases are. A histogram allows us to group purchases together so we ...
Matplotlib is a Python 2D plotting library. You can easily generate plots, histograms, power spectra, bar charts, scatterplots, etc., with just a few lines of code. The example here is plotting a histogram. The “%matplotlib inline” will make your plot outputs appear and be stored within...
