回答： Steven Lord 2019-6-14

I am trying to a plot of 3-4 vertically stacked subplots showing different quantities on the y-axis, but with the same x-axis. I use subplot(2,1,1) and (2,1,2) for the first and second plot. I try but subplot(2,1,3) for the third plot, but MATLAB returns an error - "Index exceeds number of subplots." In various publications, I have seen 3+ vertically stacked plots using the same x-axis like the one below.

Is this not possible without the creation of a second figure? Also, is there a shortcut to possibly combining subplots from two separate figures to accomplish this?

Many thanks. Star Strider. In hindsight, this was a real 'duh' moment after reading the answer.

My pleasure.

There are no ‘duh’ moments, only opportunities to learn more. With R2016b now available, those opportunities will increase, since the release notes promise even more functionality.

Hi, how did you remove the space between the subplots?

You select the mouse pointer icon and select a subplot, you can now move them closer using the arrow keys. It took me so long to figure that out, it is kind of annoying that there's no easy way built in matlab to programmatically do this kind of stacked plot that share the same x-axis data.
