Plus(+)pattern plot using python

 import matplotlib.pyplot as plt

x_horiz=[-1,1]

y_horiz=[0,0]

x_vert=[0,0]

y_vert=[-1,1]

plt.plot(x_horiz,y_horiz,'b-',linewidth=3)

plt.plot(x_vert,y_vert,'b-',linewidth=3)

plt.xlim(-2,2)

plt.ylim(-2,2)

plt.grid(True)

plt.title('Plus pattern plot')

plt.show()

Code Explanation:

1. Importing Matplotlib

import matplotlib.pyplot as plt

This imports matplotlib.pyplot, which is used for plotting in Python.

2. Defining Coordinates for the Plus (+) Shape

x_horiz = [-1, 1]  

y_horiz = [0, 0]  

This represents the horizontal line of the plus sign.

The line extends from x = -1 to x = 1, while keeping y = 0.

x_vert = [0, 0]    

y_vert = [-1, 1]   

This represents the vertical line of the plus sign.

The line extends from y = -1 to y = 1, while keeping x = 0.

3. Plotting the Horizontal and Vertical Lines

plt.plot(x_horiz, y_horiz, 'b-', linewidth=3)  

plt.plot(x_vert, y_vert, 'b-', linewidth=3)    

plt.plot(x_horiz, y_horiz, 'b-', linewidth=3)

Plots the horizontal line in blue (b).

Uses a solid line (-).

linewidth=3 makes the line thicker.

plt.plot(x_vert, y_vert, 'b-', linewidth=3)

Plots the vertical line using the same style.

Together, these lines form a plus (+) sign.

4. Setting Axis Limits

plt.xlim(-2, 2)  

plt.ylim(-2, 2)  

plt.xlim(-2, 2) sets the x-axis limits from -2 to 2.

plt.ylim(-2, 2) sets the y-axis limits from -2 to 2.

This ensures the plus sign is centered and visible.

5. Enabling Grid

plt.grid(True)

Adds a grid to the plot for better visualization.

6. Adding a Title

plt.title("Plus Pattern Plot")

Adds a title to the plot.

7. Displaying the Plot

plt.show()

This function renders and displays the plot.
