How to add a subplot

How can you add a graph as a subplot.

subplot

I can plot a stand alone graph. But I would like to add this as a subplot.

plot

graph

subplot

import pandas as pd
import matplotlib.pyplot as plt

d = ({
'A' : ['1','1','1','2','2','2','3','3','3','3'],
'B' : ['A','B','C','A','B','C','D','A','B','C'],
'C' : ['John','Carl','Carl','John','Lily','John','Lily','John','Carl','Carl'],
'D' : [1,2,3,4,5,6,7,8,9,10],
'E' : [0,2,4,6,5,6,7,8,9,10],
})

df = pd.DataFrame(data=d)

fig = plt.figure(figsize = (9,4))

def One_plot(ax,pid, fontsize=12):
ax.set_title('One Plot', fontsize=10)
ax.scatter(df['E'],df['D'])
ax.grid(False)

def Two_plot(ax,pid):
df.assign(A=df.A.astype(int)).pivot_table(index="C", columns="B", values="A",aggfunc='count').rename_axis(None).rename_axis(None,1).plot(kind='bar')
ax.set_title('Two Plot', fontsize=10)

def Three_plot(ax,pid, fontsize=12):
ax.set_title('Three Plot', fontsize=10)
ax.plot(df['E'],df['D'])
ax.grid(False)

ax1 = plt.subplot2grid((3,3), (0, 0), colspan = 3)
ax2 = plt.subplot2grid((3,3), (1, 0), colspan = 2)
ax3 = plt.subplot2grid((3,3), (2, 0))

One_plot(ax1,1)
Two_plot(ax2,1)
Three_plot(ax3,1)

fig.tight_layout()


Please see output below. I can add the subplots to Plot One and Plot Three but the bar chart gets produced as a stand alone graph. I would like to add it to Two Plot.

subplots

Plot One

Plot Three

bar chart

Two Plot

This example only displays 3 subplots. My actual code has 8. Whilst there are easier ways to achieve the above solution, I do need to use this technique.

It's not within a plot. They are two separate subplots. I have altered the question to make it clearer.

see if this solves your problem.

@AmanAgarwal I think you could mark that as duplicate? @PeterJames123 I don't understand what you're wanting to obtain. I think there are more simple ways to get two plots. Also what is your output? Deleting the line plt.show() I obtained two plots one with one subplot and one with two.

I'm not entirely sure I interpreted the question correctly...

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns

d = ({
'A' : ['1','1','1','2','2','2','3','3','3','3'],
'B' : ['A','B','C','A','B','C','D','A','B','C'],
'C' : ['John','Carl','Carl','John','Lily','John','Lily','John','Carl','Carl'],
})

df = pd.DataFrame(data=d)

fig, (ax1, ax2, ax3) = plt.subplots(1,3, figsize=(13,5))
sns.countplot(x = df.C, ax = ax1)
sns.countplot(x = df.B, ax = ax2)
sns.countplot(x = df.C, hue =df.B, ax = ax3)


Please refer to question. I have added more information. I understand there are easier ways to achieve this. My actual plot is a lot more complex as it contains numerous subplots of unequal size.

could you show what you want to obtain with a picture? I can't understand what is the output that you're trying to obtain.
