Pie Chart (Total of pie chart = value, not summation of parts)

[scotgabriel]

I want to make a pie chart that UTILIZES the following 2 inputs:

1. item-A-Used: which I'm representing in my pie-chart tracker 'data' attribute as '{{sum(dataset(0))}}'
2. item-A-LastInventoryCount : which is 'dataset(1)'

Pie chart code that isn't working:

searchType: dvField
searchTarget: item-A-Used, item-A-LastInventoryCount
datasetName: used, total
startDate: 2023-04-30
endDate: 2023-05-06

pie:
	title: Item-A used and Remaining
	data: '{{sum(dataset(0))}}, WHAT-GOES-HERE??'
	dataName: Used, Total Left
	dataColor: 'yellow,green'
	label: Used, Total Left
	extLabel: '{{sum(dataset(0))}}, Total Left'

Things I've tried to put in "WHAT-GOES-HERE??":

• {{(dataset(1))}}-{{sum(dataset(0))}}
• dataset(1)-{{sum(dataset(0))}}
• item-A-LastInventoryCount-{{sum(dataset(0))}}

I'm just not sure how to accomplish the following

• Can I do subtraction of 2 inputs so that I can define the TOTAL size of the pie chart? (otherwise my pie chart ends up being INVENTORY-TOTAL-slice + SUMofINVENTORYused-slice) but I want the 2 slices to add up to the total inventory at last count

Any help appreciated
