I need to generate two lines on one graph. One variable – T is plotted as the primary axis and I am looking to create a secondary axis for the variable ZP.

I am attempting to combine three plots into three panels for one figure. Since the three panels share the same data on the x-axis, I would like to remove the x-axis and labels for plots 1 and 2. However, I have encountered an issue where the plot region for plots 1 and 2 is much larger than that for plot 3. How can I fix this?
