Here is an example Python code that creates the Matplitlib figure, saves to a file, and loads it back: import pickle import matplotlib.pyplot as plt # create figure fig = plt.figure() plt.plot([4,2,3,1,5]) # save whole figure pickle.dump(fig, open("figure.pickle", "wb")) #...
How to Save a Python Seaborn Plot to a File? Once we have created a plot, we can save it to a file using the “savefig()” function from matplotlib. This function takes the filename as input and saves the plot to that file. The “seaborn” library allows you to save plots in vari...
In[1]:importmatplotlibimportmatplotlib.pyplotasplt Now to create and display a simple chart, we’ll first use the.plot()method and pass in a few arrays of numbers for our values. For this example, we’ll plot the number of books read over the span of a few months. In[2]: plt.plot...

Let’s have a look at an example to understand the concept of saving a plot as a pdf file in matplotlib more clearly. Example: # Import Libraryimport matplotlib.pyplot as plt# Define Datax= [0, 1, 2, 3, 4, 5] y= [1.5, 2, 3.6, 14, 2.5, 3.9]# Plotplt.plot(x,y)# Save as...
