Draft: Resolve "Plot: Make X-Axis Movable/Zoomable"

Due to limitations of pyqtgraph, this feature is not possible to implement. For this to work there has to be the possibility of re-implementing the auto-adjust of a plot, which is not possible from what I have seen.

The x axis' interactivity depends now on the X_INTERACTABLE constants in plot_constants.py. It is turned off by default.

Closes #254 (closed)
