How to plot a contour plot for two met-ocean variables (such as wind speed vs wave height as shown in attached diagram) ?

I have been stuck on this problem for a couple of days and it is driving me nuts. My project is about calculating the correlation between two different met-ocean variable such as wind-wave or wave-current, which I done by using joint probability approach. Now, I have problem to present my result in contour form. How to plot a contour plot for two met-ocean variables (such as wind speed vs wave height as shown in attached diagram) ? I also attached my data here.
