How to put two separate scales on the same x-axis?

I would like to create a plot in MATLAB with two separate scales along the x axis. I need the negative x-axis to go from -15 to 0 and have intervals of 5 and the positive x-axis to go from 0 to 0.8 with intervals of 0.1. The plot needs to have the same x-axis as the image. Thank you.

@Stephen Bompastore, I did not read your quesiton carefully enough. I see that the quesiton which @dpb answered was different than what you are asking.

The info here should be adaptable to do what you want. THat site includes instructions for making the plot below:

I am confident that you can modify those instructions to make your plot.
