Co-assigning @jessegreenberg in case I need help on this one.
The graph is actually reading correctly for the amount of mass. The problem for energy-skate-park-basics is that it started using the mass range of energy-skate-park after phetsims/energy-skate-park#6. With tiny mass, PE and KE are not visible at all with these graph scales.
The above commits fix this issue.
Also, Ill make the initial reference height zero again, I just did that to see negative values in the bar graph.
Thanks @KatieWoe, closing this issue.
I found this behavior in the graph when changing the mass of the skater in ESPB. Potential bar looks buggy and only shows up slightly, kinetic doesn't show up at all. You have to zoom in quite a lot to even see this much, even though there is a lot of movement. To reproduce, start skater with friction and wait until they are under the "0" line. Then remove friction. Make skater as light as possible. Observe graph.
