plt.plot bar code example

Example 1: how to do scatter plot in pyplot

import numpy as npimport matplotlib.pyplot as plt
# Create data
N = 500x = np.random.rand(N)
y = np.random.rand(N)
colors = (0,0,0)
area = np.pi*3
# Plot
plt.scatter(x, y, s=area, c=colors, alpha=0.5)
plt.title('Scatter plot pythonspot.com')
plt.xlabel('x')
plt.ylabel('y')
plt.show()

Example 2: matplotlib bar chart

import matplotlib.pyplot as plt

# Create a Simple Bar Plot of Three People's Ages

# Create a List of Labels for x-axis
names = ["Brad", "Bill", "Bob"]

# Create a List of Values (Same Length as Names List)
ages = [9, 5, 10]

# Make the Chart
plt.bar(names, ages)

# Show the Chart
plt.show()

Example 3: how to increase bar width in python matplogtlib

#plt stands for matplotlib.pyplot
#simple way to increase width of a bar in a bar graph
#I will eventually write out another solution for increasing width bars.
#This solution with solve a more complexed problem for increasing width bars in a bar graph.


plt.bar(x, y, width=30)

Example 4: bar plot python

import matplotlib.pyplot as plt
import numpy as np
plt.bar(np.arange(0,100),np.arange(0,100))
