Show Matplotlib plots (and other GUI) in Ubuntu

Matplotlib Ubuntu Server Side Programming Programming

Use the plot method of matplotlib and set the legend with different sets of colors.

Steps

Set the X-axis label using plt.xlabel() method.
Set the Y-axis label using plt.ylabel() method.
Plot the lines using plt.plot() method with [9, 5], [2, 5] and [4, 7, 8] array.
Initialize two variables; location = 0 for the best location and border_drawn_flag = True (True, if border to be drawn for legend. False, if border is not drawn).
Use plt.legend() method for the legend and set the location and border_drawn_flag accordingly to get the perfect legend in the diagram.
Show the figure using plt.show() method.

Example

import matplotlib.pyplot as plt

plt.ylabel("Y-axis ")
plt.xlabel("X-axis ")

plt.plot([9, 5], [2, 5], [4, 7, 8])

location = 0 # For the best location
legend_drawn_flag = True
plt.legend(["blue", "orange"], loc=0, frameon=legend_drawn_flag)

plt.show()
