Subject:	Python script to set start & end time of data browser
From:	Vishnu Patel via Tech-talk <[email protected]>

Hello,

I am trying to set start and end time of my trends in data browser with the python script

from org.csstudio.display.builder.runtime.script import PVUtil, ScriptUtil

trend = ScriptUtil.findWidgetByName(widget, "trend")

start_time_text=PVUtil.getString(pvs[0])

end_time_text=PVUtil.getString(pvs[1])

# Set the start/end time properties of the Data Browser

trend.setPropertyValue("start_time", start_time_text)

trend.setPropertyValue("end_time", end_time_text)

Here I am setting start and end time of data browser by pressing the button.

But I am getting an error,

"java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: Widget 'trend' (databrowser) has no 'start_time' property
"

How I can set time axis using python script?

Thanks

Vishnu
