Adding Color To Graphs Python - Matplotlib tutorial 4

Adding more color customization to our Python graph

This tutorial builds on the previous one, teaching you some more of the options for Matplotlib color-customization. In this video, we change the color of the x axis and y axis labels, the spine colors, and the title.

import matplotlib.pyplot as plt

x = []
y = []

fig = plt.figure()
rect = fig.patch
rect.set_facecolor('#31312e')

readFile = open('SampleData.txt','r')
sepFile = readFile.read().split('\n')
readFile.close()

for plotPair in sepFile:
    xAndY = plotPair.split(',')
    x.append(int(xAndY[0]))
    y.append(int(xAndY[1]))

ax1 = fig.add_subplot(1,1,1, axisbg='grey')
ax1.plot(x, y, 'c', linewidth=3.3)

ax1.tick_params(axis='x', colors='c')
ax1.tick_params(axis='y', colors='c')

ax1.spines['bottom'].set_color('w')
ax1.spines['top'].set_color('w')
ax1.spines['left'].set_color('w')
ax1.spines['right'].set_color('w')

ax1.yaxis.label.set_color('c')
ax1.xaxis.label.set_color('c')

ax1.set_title('Matplotlib graph', color='c')
ax1.set_xlabel('x axis')
ax1.set_ylabel('y axis')

plt.show()
