Prerequisites: Matplotlib
In this article, we will see how can we can add a border around histogram bars in our graph using matplotlib, Here we will take two different examples to showcase our graph.
Approach:
- Import required module.
- Create data.
- Add border around histogram bars.
- Normally plot the data.
- Display plot.
Below is the Implementation:
Example 1:
In this example, we will Pass an edgecolor = ‘Black’ value as the edge color parameter to plt.hist() to change the bar border color.
Python3
# importing packagefrom matplotlib import pyplot as pltimport numpy as np #create datafig,ax = plt.subplots(1,1)a = np.array([22, 87, 5, 43, 56, 73, 55, 54, 11, 20, 51, 5, 79, 31, 27]) b = (0, 25, 50, 75, 100) # Adjust the border colorax.hist(a, b, edgecolor = "black") ax.set_title("histogram - GeekforLazyroar")ax.set_xlabel('Litracy Level(%)')ax.set_ylabel('Population(million)') plt.show() |
Output:
Example 2:
In this example, we will Pass a two edge color, edgecolor = ‘Black’ and ‘red’ value as the edge color parameter to plt.hist() to change the bar border color.
Python3
# importing packagefrom matplotlib import pyplot as pltimport numpy as np #create datafig,ax = plt.subplots(1, 1) a = np.array([20, 73, 55, 31, 51, 5, 79, 5, 43, 22, 87, 54, 11, 56, 27]) b = np.array([0, 25, 50, 75, 100]) # Adjust the border colorax.hist(a, edgecolor = "black", color = 'pink')ax.hist(b, edgecolor = "red", color = 'gray') ax.set_title("Histogram - GeekforLazyroar")plt.show() |
