plot a hexplot of task n to show the point density with gridsize=30 in python

To create a hexplot in Python using Matplotlib library, you can follow these steps:

1. Import the necessary libraries:

main.py
import numpy as np
import matplotlib.pyplot as plt
51 chars
3 lines

2. Create a set of data:

main.py
x = np.random.normal(size=500)
y = np.random.normal(size=500)
62 chars
3 lines

3. Create the hexbin plot:

main.py
plt.hexbin(x, y, gridsize=30, cmap='inferno')
plt.colorbar()
plt.show()
72 chars
4 lines

This will create a hexbin plot with a grid size of 30 and a color map of 'inferno'. The color bar can be added to the plot using the colorbar() function.

Note: the size parameter in the random function is just used to generate the data. You can replace it with your own data.
