=======================
Plotting region fitting
=======================

When the ternary limits are modified, the plotting region can be expanded or
cropped in a different way via the `fit` option in e.g. `set_ternary_lim`.

- `'rectangle'` (default): Fitted to the original rectangle.
- `'triangle'`: Fitted to the original triangle.
- `'none'`: The plotting region is simply cropped (or expanded).
