The trick here is that when printing, it's natural to think in terms of inches, but when creating an image (for a web page, for instance), it is natural to think in terms of pixel size. I tried with. You can view all output files here. However, if not plotted efficiently it seems appears complicated. It is just a line chart. A larger figure size will allow for longer texts, more axes or more ticklabels to be shown. So, the syntax is something like this- matplotlib.pyplot.figure(figsize=(float,float)) Parameters- Width – Here, we have to input the width in inches. This is a small demo file that helps teach how to adjust figure sizes for matplotlib. When defining the labels of the graph using matplotlib.pyplot.xlabel(xlabel), matplotlib.pyplot.ylabel(ylabel), and matplotlib.pyplot.suptitle(t), add the parameter fontsize=int to each function call with int as the desired font size. filedialog We use figure(), set_figheight() along with set_figwidth()and set_size_inches() methods and set rcParams to change figure size in Matplotlib. figsize is a tuple of the width and height of the figure in inches, and dpi is the dots-per-inch (pixel per inch). .
