## How do you make multiple graphs in Python?

Use matplotlib. pyplot. subplot() to make multiple plots pyplot. subplot(nrows, ncols, plot_number) to create a new subplot of a current plot matplotlib. pyplot positioned at plot_number in a grid with nrows rows and ncols columns. Under each call, modify the plot as desired before the creation of another subplot.

## What is subplot in Python?

The matplotlib. pyplot. subplots method provides a way to plot multiple plots on a single figure. Given the number of rows and columns , it returns a tuple ( fig , ax ), giving a single figure fig with an array of axes ax .

## How do you use subplot?

subplot divides the current figure into rectangular panes that are numbered row-wise. Each pane contains an axes. Subsequent plots are output to the current pane. subplot(m,n,p) creates an axes in the p -th pane of a figure divided into an m -by- n matrix of rectangular panes.

## Why do we use subplots?

subplot( m , n , p , ‘align’ ) creates new axes so that the plot boxes are aligned. This option is the default behavior. subplot( m , n , p , ax ) converts the existing axes, ax , into a subplot in the same figure. subplot( ‘Position’ , pos ) creates axes in the custom position specified by pos .

## Why subplot is used in Matlab?

subplot( m , n , p ) divides the current figure into an m -by- n grid and creates axes in the position specified by p . MATLABĀ® numbers subplot positions by row. subplot( m , n , p , ‘align’ ) creates new axes so that the plot boxes are aligned. This option is the default behavior.

## What does subplot mean in Matlab?

subplot( m , n , p ) divides the current figure into an m -by- n grid and creates axes in the position specified by p . MATLABĀ® numbers subplot positions by row. The first subplot is the first column of the first row, the second subplot is the second column of the first row, and so on.
