In this program, we will plot two lines using the matplot library. Before starting to code, we need to first import the matplotlib library using the following command −
Import matplotlib.pyplot as plt
Pyplot is a collection of command style functions that make matplotlib work like MATLAB.
Algorithm
Step 1: Import matplotlib.pyplot Step 2: Define line1 and line2 points. Step 3: Plot the lines using the plot() function in pyplot. Step 4: Define the title, X-axis, Y-axis. Step 5: Display the plots using the show() function.
Example Code
import matplotlib.pyplot as plt line1_x = [10,20,30] line1_y = [20,40,10] line2_x = [10,20,30] line2_y= [40,10,30] plt.xlabel('X AXIS') plt.ylabel('Y AXIS') plt.plot(line1_x ,line1_y , color='blue', linewidth = 3, label = 'line1-dotted',linestyle='dotted') plt.plot(line2_x ,line2_y, color='red', linewidth = 5, label = 'line2-dashed', linestyle='dotted') plt.title("PLOTTING DOTTED LINES") plt.legend() plt.show()
Output
Explanation
The variables line1_x, line_y and line2_x, line2_y are the coordinates of our lines. The linewidth parameter in the plot function is basically the width/thickness of the line we are plotting. The plt.legend() function in the program is used to place legends like x-axis, y-axis names on the graph.
