A dpi of 75 is good if you want to put the image on a web page or a dpi of 250 or more is good if the image is to be included in a report or docx file. We can also decide the resolution of the saved image by changing the dpi argument. We can give any extension like ‘.png ‘, ‘.jpeg’ etc. Here, ‘line plot.jpg’ is the name of the figure saved with the extension as ‘.jpg’. Savefig( ) function explanation plt.savefig('line plot.jpg',bbox_inches='tight', dpi=150) fig.savefig() function is called before the plt.show( ).plt.figure() function is called first and then the plotting function.We can set the figure size with the plt.figure( ) function.

png etc and a resolution in dpi (dots per inches) to the saved image.Ĭonsider the graph as shown above and its code import matplotlib.pyplot as plt We need to add 1 to this number as enumerate starts counting from zero, but plt.subplot starts counting at 1. We used Python’s enumerate function so we could record the index position (n) of the list as we iterate it. This function saves the figure in the current working directory. Here we used the plt.subplot syntax inside the loop and specified which subplot index we should plot the data. We can save a matplotlib plot by using the savefig( ) function.
