The final part to remember is that the axes shape/size is defined as a percentage of the figure's shape/size. So in order to obtain a figure with a pixel size of e. You may interlace two grids such that there is a larger spacing between every second subplot. –1. It means that any plotting command we write will be applied to the axes ( ax) object that belongs to fig. Automatic placement of colorbars# The simplest case is just attaching a colorbar to each axes. The second figure demonstrates how the styles of the artists can be customized.
