Hello, should creating a histogram with masked data be different that one cretated with unmasked data? Is np.hist tuned for work with historams?
I R_project I would do: # Note: values is my dataset ### masking zeros values_mask=ifelse(values==0, NA, (values)) # http://stat.ethz.ch/R-manual/R-patched/library/stats/html/ecdf.html plot(ecdf(values_mask), main="Emprical cumulative distribution function", do.points=F, xlab='Data Values') There masking the zeros has an effect. With pure numpy not. Thanks in advance for any comment.
