Easy Chart - Reset Axes via Scripting

Ignition
1

Hi,

If I override the right-click context menu on an Easy Chart using system.gui.createPopupMenu, is there a way to perform the reset axes, zooms, etc from the original context menu via scripting? The only thing I know how to do is use setMode to change between Zoom, Pan, X-Trace, etc.

#in mouseReleased event handler
def setXTrace(event=event):
	event.source.setMode(4)

def setZoom(event=event):
	event.source.setMode(0)

def setPan(event=event):
	event.source.setMode(1)

def resetAxes(event=event):
	print "how do I do this?"

#right click only
if event.button == 3:
	menuDict = {}
	menuDict["Zoom Mode"] = setZoom
	menuDict["X-Trace Mode"] = setXTrace
	menuDict["Pan Mode"] = setPan
	menuDict["Reset Axes"] = resetAxes
	menu = system.gui.createPopupMenu(menuDict)
	menu.show(event)

Thanks!

Dan

Do the following:[code]#in mouseReleased event handler
def setXTrace(event=event):
event.source.setMode(4)

def setZoom(event=event):
event.source.setMode(0)

def setPan(event=event):
event.source.setMode(1)

def resetAxes(event=event):
event.source.createChart()

#right click only
if event.button == 3:
menuDict = {}
menuDict[“Zoom Mode”] = setZoom
menuDict[“X-Trace Mode”] = setXTrace
menuDict[“Pan Mode”] = setPan
menuDict[“Reset Axes”] = resetAxes
menu = system.gui.createPopupMenu(menuDict)
menu.show(event)[/code]

Hi Travis,

When I call event.source.createChart(), I get this error:

Traceback (innermost last):
File “event:mouseReleased”, line 11, in resetAxes
AttributeError: createChart

Thanks,

Right, I am sorry. That function doesn’t exist on the easy chart. It doesn’t look like we have a public reset axes function. You can try event.source.initialize().

Initialize didn’t work either.

No problem, thanks for getting back to me. It would be great if those functions could be exposed, though.

I think I can toggle a value on the chart (like autoApply) off and on which will cause the graph to reset. The only catch is all the queries will refresh.

Thanks,

Dan

Ok, I will see what we can do about exposing the functions.

You can trick an easy chart into resetting its axes like this:

chart = event.source.parent.getComponent("Easy Chart") chart.axes=chart.axes
