Look at Examples, Plots, Stripchart.

The stripchart is like a databrowser widget but instead of a *.plt file you provide PV names.

 

Put that into an embedded widget, and check the example https://github.com/ControlSystemStudio/phoebus/blob/master/app/display/model/src/main/resources/examples/embedded/update_display.py

for a way to update what’s shown inside an embedded widget.

 

That way, your checkboxes etc. can trigger a script to update the embedded widget, inside which you can have whatever, including a strip chart for the desired PVs.

Subject: [EXTERNAL] CSS-Phoebus: Dynamically changing the contents of embedded databrowser

Hi,

 

hoping to find some Phoebus experts here to tell me if this is at all possible.

 

I have a Phoebus display, where a user can check a bunch of checkboxes to activate/deactivate indicators on a drawing of a chamber for a series of pressure, temperature, and flow sensors. Now, I would like to also have an embedded databrowser there to display those PVs that are marked by checked checkboxes.

Is there a way to change, by using embedded scripts or by connecting to a PV, the contents of an embedded databrowser? Either by dynamically adding and removing PVs from it or by hiding/showing PV traces, i.e., accessing the right-click runtime settings of the embedded databrowser?

 

I can load a different plt-file, by changing that property, but that requires previously created plt-files for all combinations of PVs to be displayed. I would like some other way to manipulate the PVs displayed in an embedded databrowser window at runtime. Does that exist?

 

Thanks and cheers,

Malte
