# Stratified Graph

Stratified graph is not the kind of
Bar Plot
,
Histogram
and so on.
"Stratify" is one of the process to make graphs.

Left is non-stratified, right is stratified.
Data is same.

This example is
Box Plot
.
But
stratified sampling
is useful for any types of graphs.

We can compare easily by stratified graphs.

##
Data Type for Stratified Graph

Right type is easier to add data.

##
R and Python

There are not many software that can divide graphs by categorical data.

I use
ggplot2
in R.
And
seaborn
in Python.
