plotting histogram - vvv - Mar-10-2017
Hi All,
I count the number of grades appeared in the dataset and trying to plot it as histogram.
it works ,but couldn't get the grade name as x-axis.
data on the count dataframe looks like
Vermin V
V1 1
V10 1
V11 1
V2 1
V3 2
V4 2
V5 3
V6 6
V7 4
V8 2
V9 1
dtype: int64
i tried the below code
>>> plt.hist(vermin_v)
(array([ 5., 0., 3., 0., 1., 0., 1., 0., 0., 1.]), array([ 1. , 1.5, 2. , ..., 5. , 5.5, 6. ]), <a list of 10 Patch objects>)
i am getting a histogram ,but the numeric values appear on x-axis instead of vermin grades.
how can i get the vermin grades v1,v10etc on the x axis?
Thanks
vvv

Are you sure that you want a histogram? As a histogram is to show distribution of numerical data, there are usually no labels beside numeric values on x axis ...
Perhaps you want just ordinary barplot, showing counts V1, V2 etc? If so, then easiest way is to use directly your pandas series with value counts:
count_serie.plt('bar')plots barplot and uses index values (your V1, V2 ...) as labels.
