I have an experimental image as shown (16 pixels in the image = 1millimeter) -
I have my simulation results plotted as follows ( x-axis is the radius vector in meter and y-axis is the corresponding height vector in meter)-
Now I want to plot my simulation results on top of the experimental figure to compare both of them. How should I do it.
I tried to first use imshow( experimental image) and then hold on and then plot( radius, height) for the simulation result. But the problem is that both the figures/plot are not in the same scale. For the experimental image I have 16 pixels per mm while I only know the simulation results in meters. How should I proceed?

You can use image and proved the x-axes and y-axes limits as in your plot use hold on and plot the data. Now the (x,y) data of both the images will sync up.
