如何在MatplotLib中使用子图绘制BarPlot或直方图？

Question

• I want to draw Grid of Bar graph/Histogram for my data.My Data contains 1 NUMERIC and 3 CATEGORICAL Column
• PAIRGraph is not suitable for my purpose as my purpose as I have only 1 Numeric and 3 Categorical Column

Tried to Refer Documentation https://matplotlib.org/api/_as_gen/matplotlib.pyplot.subplots.html

However, I am unable to find exact way to fulfill my requirement.

Using Demo code I am able to draw only LineGraph. However, I am required to draw Bar Graph.

fig, axes = plt.subplots(1, 2, figsize=(10,4))
x = np.linspace(0, 5, 11)
axes[0].plot(x, x**2, x, np.exp(x),x,20*x)
axes[0].set_title("Normal scale")
axes[0].plot

axes[1].plot(x, x**2, x, np.exp(x))
axes[1].set_yscale("log")
axes[1].set_title("Logarithmic scale (y)");

Please feel free to correct my approach or guide me as I have just started learning.

Answer 1

If you specify exactly what you want to use for the bar and hist , I can modify, but generally it is simply changing the plot to the type of chart you need

import matplotlib.pyplot as plt
import numpy as np
fig, axes = plt.subplots(1, 2, figsize=(10,4))
x = np.linspace(0, 5, 11)
axes[0].bar(x,x**2) # bar plot
axes[0].set_title("Normal scale")
axes[0].plot

axes[1].hist(x) # histogram
axes[1].set_yscale("log")
axes[1].set_title("Logarithmic scale (y)");

plt.show()

Answer 2

After going through the API documentation from Matplotlip Subplot Axes, I found ways to draw different graph not just Line graph.

https://matplotlib.org/api/axes_api.html

DEFAULT:-

• axes[0].plot by-default draws line graph.

CUSTOM GRAPH:-

• axes[0].bar can be used to draw BAR graph in selected Subplot

• axes[0].scatter can be used to draw Scatter graph in selected Subplot

• axes[0].hist can be used to draw a histogram . in selected Subplot

Like above example more graph can be drawn with below API:-
