matplotlib show graph code example

Example 1: how to plot a graph using matplotlib

from matplotlib import pyplot as plt
plt.plot([0, 1, 2, 3, 4, 5], [0, 1, 4, 9, 16, 25])
plt.show()

Example 2: show graph matplotlib axes

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

df = pd.read_csv("filesc/file1.csv")
df.head()

BBox = ((df.x.min(),   df.x.max(), df.y.min(), df.y.max()))

ruh_m = plt.imread('map.png')

print(BBox)

fig, ax = plt.subplots(figsize = (8,7))
ax.scatter(df.x, df.y, zorder=1, alpha= 0.2, c='b', s=10)
ax.set_title('Plotting Spatial Data on Map')
ax.set_xlim(BBox[0],BBox[1])
ax.set_ylim(BBox[2],BBox[3])
ax.imshow(ruh_m, zorder=0, extent = BBox, aspect= 'equal')
plt.show()

Example 3: matplotlib graph

matplotlib Graph
-------------------------------
import matplotlib.pyplot as plt  
x = [1, 2, 3, 4, 5] 
height = [10, 20, 30, 40, 50] 
tick_label = ['one', 'two', 'three', 'four', 'five'] 

plt.bar(x, height, tick_label = tick_label, 
		width = 0.5, color = ['red', 'green']) 

plt.xlabel('x  axis') 
plt.ylabel('y axis') 
plt.title('matplotlib Graph') 
plt.show()

Example 4: matplotlib show plot

import matplotlib.pyplot as plt

plt.plot(x, y)
plt.plot(z, t)
plt.show()
