Hi Henrik,
To some extent, this is possible to do using a script run in Veusz --
it's probably not a _supported_ usage, but it works. The key is that you
can import PyQt4 from the scripting command line and it works. If you
open the example Help->Example documents->fit and paste the following
lines into the command prompt, you'll see that the data points update
once a second, and so does the fit:
def timerFn():
d, symerr, poserr, negerr = GetData('y')
d *= 1.1
SetData('y', d, symerr=symerr, poserr=poserr, negerr=negerr)
Action('fit', '/page1/graph1/fit1')
from PyQt4 import QtCore
timer = QtCore.QTimer()
timer.timeout.connect(timerFn)
timer.start(1000) # run once per second
The contents of timerFn can probably be almost anything that you could
type at the Veusz command line; I've tested GetData(), SetData(), Set(),
Action(), and Export() and they all work. (Although print() doesn't
work, I checked that.) In particular, you could do
def timerFn():
ReloadData()
Export('myplot.eps') # and customize your settings
and it should work. If this works for you, please let me know. (Though
as I said, this is probably totally unsupported and may crash randomly
-- though since QTimer is fired through the event loop, it should be
much more stable than e.g. trying to fire off a QThread.)
Regards,
