scatter() Scatter plots are used to observe relationship between variables and uses dots to represent the relationship between them. The scatter() method in the matplotlib library is used to draw a scatter plot.

What is matplotlib scatter plot?

Scatter plot is a graph of two sets of data along the two axes. In python matplotlib, the scatterplot can be created using the pyplot. plot() or the pyplot. scatter() . Using these functions, you can add more feature to your scatter plot, like changing the size, color or shape of the points.

When would you use a scatter plot?

Use a scatter plot when you have two variables that pair well together. If you have two variables that pair well together, plotting them on a scatter diagram is a great way to view their relationship and see if it's a positive or negative correlation.
