Constant size

To change the size of all markers in Matplotlib, specify the s argument in plt.scatter(~):


        
        
            
                
                
                    x = [1,2,4]
y = [3,3,3]
plt.scatter(x, y, s=100)
plt.show()

This produces the following output:

Variable size

To vary the size of individual markers, pass in an array instead:


        
        
            
                
                
                    x = [1,2,4]
y = [3,3,3]
sizes = [5,50,500]
plt.scatter(x, y, s=sizes)
plt.xlim(0,5)
plt.show()

The output is as follows:
