How to set a grid graph line in Python
Adding grid lines to the graph plot
First, we have to install two modules:
import matplotlib
import matplotlib.pyplot as plt
Then, we enter the code:
import numpy as npimport matplotlib.pyplot as pltx = np.array([80, 82, 90, 95, 100, 103, 110, 115, 120, 125])y = np.array([240, 250, 264, 270, 280, 290, 294, 310, 320, 330])plt.title("Health Chart")plt.xlabel("Average people")plt.ylabel("Calorie Consumption")plt.plot(x, y)plt.grid()plt.show()
Specifying which grid lines to display
We can use the "axis" parameter in the grid function to specify which grid lines to display.
Legal values are 'x', 'y', and 'both'. The default value is 'both'.
import numpy as npimport matplotlib.pyplot as pltx = np.array([80, 82, 90, 95, 100, 103, 110, 115, 120, 125])y = np.array([240, 250, 264, 270, 280, 290, 294, 310, 320, 330])plt.title("Health Chart")plt.xlabel("Average people")plt.ylabel("Calorie Consumption")plt.plot(x, y)plt.grid(axis = 'x')plt.show()
Setting line properties for the grid
import numpy as npimport matplotlib.pyplot as pltx = np.array([80, 82, 90, 95, 100, 103, 110, 115, 120, 125])y = np.array([240, 250, 264, 270, 280, 290, 294, 310, 320, 330])plt.title("Health Chart")plt.xlabel("Average people")plt.ylabel("Calorie Consumption")plt.plot(x, y)plt.grid(color = 'yellow', linestyle = '--', linewidth = 1.5)plt.show()
The graph shown above is the output.
This is how to plot grid lines in a graph.
