To change the value, we must first decrease it. Alpha has a default value of 1.0, which means it is completely opaque. Matplotlib’s ability to change the background color of the legend makes it possible. Python employs two functions to set an image as a background: imread and imshow. In this case, white will be replaced by light green. The following steps can be used to change the background color of a plot. By utilizing this library, we can change the background color of the plot. Matplotlib is one of the most widely used data visualization libraries in Python. This function takes a color argument that can be a color string, an RGB or RGBA tuple, or a numeric color code. In order to change the background color in matplotlib, you will need to use the set_facecolor() function. To set the ‘InvertHardcopy’ property to ‘on’, you can use either of the following two syntaxes: figure(‘InvertHardcopy’,’on’) or set(gcf,’InvertHardcopy’,’on’) How Do I Change The Background Color In Matplotlib? For example, if the background color of a figure is set to white, then setting the ‘InvertHardcopy’ property to ‘on’ will cause the figure to be printed or saved with a black background. If it is set to ‘on’, then the background color of the figure will be inverted when it is printed or saved to a file. For example, to set the background color of a figure to light gray, you can use either of the following two syntaxes: figure(‘Color’,) or figure(‘Color’,) The ‘InvertHardcopy’ property can be set to ‘on’ or ‘off’. The ‘Color’ property can be set to any of the MATLAB predefined colors, or to a custom color specified as an RGB triplet. The second way is to set the ‘InvertHardcopy’ property to ‘on’. The first way is to set the ‘Color’ property of the figure directly. There are two ways to change the background color of a figure in MATLAB.
