Show Matplotlib Plots and Other GUI in Ubuntu

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()
