with an existing plot using the same behaviour as what you could do with the
mouse.
`plotinit` can be used before an acquisition and remains valid only for this next scan. It selects the counters to be displayed when reading back a scan from the database (redis). All counters will be acquired and stored.
The default plot for meshes uses a ➊ scatter plot, with an image based rendering.

solid rendering.

The demo session provides motor encoders configured to follow `sy` and `sz`but
including noice. THis can be used to simulate displacements in the scans.

### Editing Lima ROIs
Lima ROIs can be edited with `edit_roi_counters` command. This BLISS command is
based on a Flint programming interface which also can be used for user scripts.
Lima ROIs can be edited from within BLISS by way of the `edit_roi_counters` command. This command uses the Flint programming interface, which is available for user scripts.
