The figure created can be saved to our local machines by using this method. Example: When we normally save a plot into pdf file. The dots values are defined in pixels. Then, we imported the numpy library for creating x coordinates and y coordinates. Python is one of the most popular languages in the United States of America. We gave Scatter.png as a file name. When using the dpi argument, we can change the size or increase it depending on our preferences. Finally, the orientation is 'landscape,' which saves the figure in landscape mode. Bug Report: saved Figure ignores figure.facecolor #17467 - GitHub The first elements in each of these color series needs to be ordered from 0 to 1, with arbitrary spacing inbetween. matplotlib.pyplot.savefig (fname, facecolor = None) Example: # Import Library import matplotlib.pyplot as plt import numpy as np # Define Data x = [1, 2, 3, 4, 5] y = [1, 2, 3, 4, 5] # Plot plt.plot (x, y) # Save image plt.savefig ('save png change background.png', facecolor ='orange') # Generate Plot plt.show () To save the array as png image we use the imsave() method. This argument describes the resolution in which the image is created. When we pass the bbox_inches argument to savefig() method and set its value to tight, it removes its border. At present, you can set the savefig colors in rcParams or via savefig kwargs. pyplot.savefig - Matplotlib 3.1 - W3cubDocs The savefig() function creates a scatter plot by combining x and y coordinates. The given portion of the image is only saved. In this example, the data points are unordered; hence this example describes the scatter plot properly. The main objective of this method is to save a graph to your local system memory. It's a confusing and inconsistent default, though!) For this firstly, you have to plot the bar chart and after that save it in pdf form. The text was updated successfully, but these errors were encountered: Good point; I agree, the rcParams should be respected. Matplotlib: show colormaps SciPy Cookbook documentation This argument takes a list as value to this argument. Once the plotting is over, it is first saved using the savefig() function. Matplotlib.pyplot.savefig () As the name suggests savefig () method is used to save the figure created after plotting data. About: matplotlib is a python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. Now I tell you the solution to solve this problem. The matplotlib library consists of all the functions for plotting different types of graphs and charts. All interactive backends, that I have tested, default to a white facecolor while ignoring the 'savefig.facecolor' rcParam. E.g. import matplotlib.pyplot as plt import numpy as np x = np.arange ( 0, 10, 0.1 ) y = np.sin (x) plt.plot (x, y) plt.savefig ( 'saved_figure.png', transparent= True ) If we put this image on a dark background, it'll result in: Changing Plot Colors You can change the face color by using the facecolor argument. The figure created can be saved to our local machines by using this method. Read: Python plot multiple lines using Matplotlib. Check out my profile. I'm not sure if this is a safe thing to depend on. By using the dpi argument we can increase and decrease the size of the figure as per your choice. Also, the facecolor is 'g,' which gives the green color. : The metadata argument takes a dictionary as value to this argument.
