Customize grid color and style

Adjust marker sizes and colors in Scatter Plot:

You can add grids by calling pyplot.grid(). The pyplot.grid() function takes the parameters such as linewidth (lw), linestyle (ls), and color (c)

import matplotlib.pyplot as plt
import matplotlib.colors

# Prepare a list of integers
val = [2, 3, 6, 9, 14]

# Prepare a list of sizes that increases with values in val
sizevalues = [i**2*50+50 for i in val]

# Prepare a list of colors
plotcolor = ['red','orange','yellow','green','blue']

# Draw a scatter plot of val points with sizes in sizevalues and
# colors in plotcolor
plt.scatter(val, val, s=sizevalues, c=plotcolor)

# Draw grid lines with red color and dashed style
plt.grid(color='red', linestyle='-.', linewidth=0.7)

# Set axis limits to show the markers completely
plt.xlim(0, 20)
plt.ylim(0, 20)

The following is the output that will be obtained:
