How can I switch the X-Axis of the plot to a different property?

A user asked over email:

Q: Hash defaults to the simulation step as the x-axis in plots. How can I switch that to be a different variable? For example, I count a time_step each time the back and forth iteration reaches convergence but it takes x-number of simulation steps to get there. I want to have the time_step on the x axis and not the simulation step.

You can use the line plot type in Analysis to set an alternative x-axis property, for instance to a custom time_step, instead of the simulation time step.
