text: Title: BUG: Running into issues with `RadarDisplay.plot_vpt` time axis
  Body: When setting `time_axis_flag` = True within `plot_vpt`, Matplotlib runs into error stating:
  
  ```python
  TypeError: Dimensions of C (600, 1736) are incompatible with X (1736) and/or Y (601); see help(pcolormesh)
  ```
  
  @zssherman mentioned that he had fixed this issue in another plotting view (#1025), which provides some hints on how to fix this issue..
