Type of Change

• NEW BECConnector → mixin class for creating connection with client and getting shortcuts for bec services, can be inherited by other widgets. Provides also basic config with widget_class and gui_id.
• NEW BECFigure → container for BECPlotBase widgets
• NEW BECPlotBase → base class for plotting widgets
• NEW BECWaveform1D → replacement of BECMonitor, serves to plot 1D scan_segment data
• NEW CLI → CLI client/server for RPC access thought terminal

Potential side effects

Additional Comments

How to test:

1) Terminal with CLI

This version has limited API defined by USER_ACCESS of the widget class. To test in terminal start ipython, then you can import CLI version of BECFigure:

from bec_widgets.cli.client import BECFigure

# Create instance of BECFigure with gui_id 'test'
fig = BECFigure('test')

# Popup figure
fig.show()

# Add Waveform widget
w1 = fig.add_plot()

# Add curve to w1 which will tack scan_segment
w1.add_curve_scan('samx','bpm4i',validate_bec=True) # this will ATM trigger ValueError: Unknown type, however functionality is not affected

2) Debug jupyter console UI

For accessing the whole API, including references from inherited object you can run:

python -m bec_widgets.widgets.figure.figure

Definition of Done

• [ ] Documentation is up-to-date. → will be done later #93 (closed)
• Unit Tests - widgets
• [ ] Unit Tests - RPC → postponed, there is some bug with testing RPC with BECDispatcher not connecting signals for scan_segment #94 (closed)
• [ ] Figure reconstruction by configs → not priority ATM #95 (closed)
• Fix RPC access to BECCurve items.
