Display motor position in Flint
Closes #1188 (closed), #1189 (closed)
This MR fixes Flint regression when using bliss command like goto_cen
.
- Create a
MotorPosition
item in Flint - Create an API in
flint_api
to updateMotorPosition
- Fix the bliss side to call the API
- Add unittest for the API
Behaviour
- There is a single motor marker per plot
- It is updated every time it is requested
- For a new scan, if the scan uses the same acquisition chain, the marker remains in place
- To be visible (and updated) the plot have to use the motor channel as the x-axes
- If it is not the case, the motor position is ignored displayed
