I can't tell easily about the distribution of data points looking at
histograms, since I am calling boxplot as in following notation:
In [32]: d[2][8:]
Out[32]: array([98.2507, 99.6293, 100.0359, 100.1859, 100.4691])
Here the elements of my array are 5th, 25, 50, 75, 95th percentile of the
original data array, where these are created with a simple calculation
before boxplot command is called.
For example when I do, boxplot([5,25,50,75,95]) I get the desired effect
exactly. For some reason in my case 2 out of 12 boxplot has fliers instead
of whiskers to be drawn. Might this be related to rounding off these
numbers?
Thanks.
