  3. Apply the scale to data going forward.

figsize () takes two parameters- width and height (in inches). By default the values for width and height are 6.4 and 4.8 respectively. Where, x and y are width and height respectively in inches. We can permanently change the default size of a figure as per our needs by setting the figure.figsize.

What are the values of figsize in Matplotlib?

The values of the figsize attribute are a tuple of 2 values. The width is the first parameter of the figsize attribute and the height is the second parameter. So it is, figsize (weight,height)
