How to export plots from matplotlib with transparent background?
I am using matplotlib to make some graphs and unfortunately I cannot export them without the white background.
In other words, when I export a plot like this and position it on top of another image, the white background hides what is behind it rather than allowing it to show through. How can I export plots with a transparent background instead?
Use the matplotlib
savefig function with the keyword argument
transparent=True to save the image as a png file.
In : x = np.linspace(0,6,31) In : y = np.exp(-0.5*x) * np.sin(x) In : plot(x, y, 'bo-') Out: [<matplotlib.lines.Line2D at 0x3f29750>] In : savefig('demo.png', transparent=True)
Of course, that plot doesn't demonstrate the transparency. Here's a screenshot of the PNG file displayed using the ImageMagick
display command. The checkerboard pattern is the background that is visible through the transparent parts of the PNG file.
