Matplotlib: Saving Plots to Files
Python open source drawing library
After creating a graph, we might need to include it in a report or share it with others.
Saving
Plots to Files
•
After creating a graph, we might need to include it in a report or share it
with others. Matplotlib allows us to save any plot like saving an image.
•
The function plt.savefig() is used
to save the plot.
Syntax
plt.savefig("filename.format")
where
filename:
It is the name of which we want to give it to our file.
format:
It is the type of image. It can be .png, .jpg, .pdf or .svg file.
Demo example
Step 1:
Create
a Python script that uses Matplotlib and draws a simple line plot.
import matplotlib.pyplot as plt
x = [1,2,3,4,5]
y = [10,20,25,30,40]
plt.plot(x,y)
plt.title("Simple Line Plot")
plt.xlabel("X‒axis")
plt.ylabel("Y‒axis")
plt.savefig("my_plot.pdf")
plt.show()
Step 2:
Open
my_plot.pdf which gets created at
the current working directory. This pdf file stored the plot created by above
Python program.
