plutoplot searchs for the gridfile and simulation data first in `sim_dir`,
then in `sim_dir/data`, and then looks up the data directory in `pluto.ini`.
Default: Current working directory
- `format`: file format of the simulation data, currently supports `double` and `float`
- `format`: file format of the simulation data, currently supports `dbl`, `flt`, `vtk`
in both `single_file` and `multiple_files` mode.
Default: `double` and `float` are tried in that order
Default: `dbl`, `flt`, `vtk`, are tried in that order
- `coordinates`: coordinate system of the simulation grid.
Supports `cartesian`, `spherical`, `polar`, `cylindrical`.
Only necessary for projecting the grind into a cartesian system (e.g. for plotting).
