By using invert_xaxis () and invert_yaxis () method we can flip the x-axis and y-axis respectively. The syntax is as given below: # Invert x-axis. matplotlib.axes.Axes.invert_xaxis(self) # Invert y-axis.

First, load in the image, the generate (x,y) pairs for each intensity in the image. This is done with meshgrid. Once you do this, use scatter to plot each point assuming z = 0 and make the colour of each point the actual intensity seen at the image coordinate. However, you will only see this in a 2D perspective as scatter is naturally 2D.In Matplotlib we can reverse axes of a graph using multiple methods. Most common method is by using invert_xaxis () and invert_yaxis () for the axes objects. Other than that we can also use xlim () and ylim (), and axis () methods for the pyplot object.
