Updating Template Canvas dataset to "draw" dots

Ignition
, ,
1

Hi.

I’m currently testing out drawing “Dots”(template) within a Template Canvas.
These “Dots” would act as an overlay over an svg-drawing to represent alarms. Each tag got 2 Associated Properties( xPos, yPos), which are extracted from the alarmStatus() object.
The script is working and the drawing of the dots do happen, but I recieve a few exceptions every time the script is called.
Anyone able to understand what is going on?

Edit: I’m currently manipulating the dataset of the Canvas Template.

As seen in the script, no event is either parsed to the method nor referenced in the script.

 NameError: global name 'event' is not defined

[details=Script][code]
def GetActiveUnackedCoordinates():
import system
import re
alarmList = system.alarm.queryStatus(state=[“ActiveUnacked”])

aProp0 = "name"
aProp1 = "xPos"
aProp2 = "yPos"

h1 = "name"
h2 = "template"
h3 = "x"
h4 = "y"
h5 = "width"
h6 = "height"
h7 = "z"

h2Value = 'Dot'
h5Value = '10'
h6Value = '10'
h7Value = '0'

headers = [h1, h2, h3, h4, h5, h6, h7]
aProps = [aProp0, aProp1, aProp2]
dataList = []
data = []

k = 0
j = 0
while k < len(alarmList):
	#Convert to string
	alarmToSearch = str(alarmList[k])
	while j < len(aProps):
	
		search = r'\b\w*' + aProps[j] + r'=(\w*\b)'
		r = re.compile(search)
		temporary = (''.join(r.findall(alarmToSearch)))
		dataList.insert(j,temporary)
		j += 1
	
	data.append([dataList[0], h2Value, dataList[1], dataList[2], h5Value, h6Value, h7Value])

	k += 1
	j = 0
try:
	return system.dataset.toDataSet(headers, data)
except ValueError:
	 system.gui.warningBox("Something isn't right")
#table = event.source.parent.getComponent("MainSiteCanvas")

#table.data = ds
#return table

Take a closer look at your exception. It’s coming from the template, not the template canvas. Line 14 of initializeTemplate.

This was embarrassing. THanks for pointing it out. I had previously put some code within the element itself as described.
(Right Click->Scripting->InitializeTemplate).
When removed it worked flawlesly.

Now I need to figure out how to call the script whenever an alarm is triggered and not by a timer.
