Hello all

I am trying to create a plot in matplotlib where I have 2 x data sets, Data Set 1 which has a list of XY co-ordinates (where the Y values are always positive) and Data Set 2 which has the same X values but different Y values and these Y values are all negative.

I want to plot both data sets on the same plot but share the X axis.

I was hoping to create a plot similar to the one attached.

Does anyone have any ideas?

Thank you.

Did you try .twinx axes method?

ax1 = ax0.twinx()
ax1.plot(...) # ax0 and ax1 share x-axis.
