This results in three new image files on our local machine, each with a different DPI: Let's test out a couple of different options: import matplotlib.pyplot as pltįig.savefig( 'saved_figure-50pi.png', dpi = 50)įig.savefig( 'saved_figure-100dpi.png', dpi = 100)įig.savefig( 'saved_figure-1000dpi.png', dpi = 1000) This is essentially the resolution of the image we're producing. The DPI parameter defines the number of dots (pixels) per inch. We'll go over some popular options in the proceeding sections. Here, we've specified the filename and format.Īdditionally, it accepts other options, such as dpi, transparent, bbox_inches, quality, etc. The savefig() function has a mandatory filename argument. You can also use it on a Figure object: import matplotlib.pyplot as plt Of the problems that you have encountered.It's worth noting that the savefig() function isn't unique to the plt instance.

So that you can report it in the right place. If you try to reproduce the issue in an example that uses only matplotlib, May be due to a problem in matplotlib rather than one in seaborn. If you’ve encountered an error, searching the specific text of the messageīefore opening a new issue can often help you solve the problem quickly andīecause matplotlib handles the actual rendering, errors or incorrect outputs If you can only demonstrate the issue with yourĪctual dataset, you will need to share it, ideally as a csv. Otherwise, it is preferable that your example generate synthetic data to The specific versions of seaborn and matplotlib that you are working withīug reports are easiest to address if they can be demonstrated using one of theĮxample datasets from the seaborn docs (i.e. The output that you are seeing (an image of a plot, or the error message)Ī clear explanation of why you think something is wrong
