How to plot multiple graphs from file for each 3 columns ? in python

Question

I don't see the strategy to work on it. I have a file, with several columns, each 3 columns represent a graph. The first column are the title and the two others column are x and y.

"Body"	"x"	"y "	"Skin"	"x"	"y "	"Head"	"x"	"y "
	0	100		0	100		0	100
	1	99		0	99		0	98

I would like to have multiple graph. I thought that the solution would be to separate the table over 3 but it's not very smart. I didn't find a function in panda or matplotlib. Do you have an idea?

Thank you

Answer 1

You could iterate over the columns like this:

for i in enumerate(df.columns):
    if i%3 == 2:
        _title = df.iloc[0,i-2]
        x = df.iloc[:,i-1]
        y = df.iloc[:,i]
        plt.plot(x, y)
        plt.show()

    

Answer 2

try this:

import matplorlib.pyplot as plt
import pandas

fig, ax = plt.subplots(3,1, figsize=(30,5))
ax.ravel()
for i, axis in enumerate(ax):
  sns.lineplot(x=df.iloc[:, 1+3*i], y=df.iloc[:, 2+3*i], ax=axis)
  axis.set_title(df.columns[0+3*i])
