1 year ago Sure, that's easy. With a script you can do pretty much anything. But beware that when you create a script, it will then be up to you to maintain it. I'm not making any promises that this will work in the next iteration of this or any other display tool:
# Embedded python script
# Attach to a DataBrowserWidget,
# triggered by a PV like "loc://save(0)".
#
# Then add a button that writes 1 to that PV
#
# --> This script runs and saves data from the plot
from org.csstudio.display.builder.runtime.script import PVUtil, ScriptUtil
from org.csstudio.trends.databrowser3.export import SpreadsheetExportJob, Source, ValueFormatter
from org.phoebus.archive.vtype import Style
from org.phoebus.framework.jobs import JobManager
# Was the PV set to 1?
if PVUtil.getDouble(pvs[0]) > 0:
# Reset PV to zero
pvs[0].write(0)
# Start with checking the widget type
print(widget.__class__.__name__)
# Should be 'DataBrowserWidget'.
# Spend some quality time reading the CS-Studio
# source code to see what you can do with a DataBrowserWidget
# Get representation, should be 'DataBrowserRepresentation'
representation = widget.getUserData(widget.USER_DATA_REPRESENTATION)
print(representation.__class__.__name__)
# Since it's a DataBrowserRepresentation, get the model
db = representation.getDataBrowserModel()
print(db.__class__.__name__)
# Then either dump the data yourself, or use for example
# the spreadsheed exporter
range = db.getTimerange().toAbsoluteInterval()
exporter = SpreadsheetExportJob(db, range.getStart(), range.getEnd(),
Source.PLOT, 0,
ValueFormatter(Style.Decimal, 3),
"/tmp/demo.dat",
None, False)
JobManager.schedule("Save data", exporter)
Is there any way to export the data in the range where Data Browser (linked to *.plt) embedded in the .OPI file is displayed to CSV? I would like to be able to output to CSV by writing it in JavaScript or other script and linking it to the Action Button.
