Histogram¶

1xNumeric¶

Using matplotlib¶

In [282]:

plt.figure(figsize=(10,3))

plt.subplot(1,2,1)
plt.hist(mydf.value1);  # default 10 bins

plt.subplot(1,2,2)
plt.hist(mydf.value1, bins=15);

Using Plotnine¶

plotnine.ggplot( dataframe, aex(x='colName')) + geom_histogram( bins=10 )
plotnine.ggplot( dataframe, aex(x='colName')) + geom_histogram( binwidth=? )

In [283]:

from plotnine import *
plotnine.options.figure_size = (3, 3)
ggplot(mydf, aes(x='value1')) + geom_histogram()  # default bins = 10

1xNumeric + 1xCategorical¶

plotnine.ggplot( dataframe, 
                    aes(x='colName'), 
                    fill='categorical-alike-colName') 
+ geom_histogram()

In [284]:

ggplot(mydf, aes(x='value1', fill='grp')) + geom_histogram(bins=15)
