How to test

1. Calculated variable chart_data in variant sends Results array link to variant: https://studio.formsort.com/client/erictest/flow/custom-question/variant/main/variables/calculated_inline

2. Labels and data from chart_data are sent as:

Result: [
	{ labels: 0, data: 300 },
	{ labels: 1, data: 300 },
	{ labels: 2, data: 283 },
	{ labels: 3, data: 266 },
	{ labels: 4, data: 250 },
	{ labels: 5, data: 233 },
	{ labels: 6, data: 216 },
	{ labels: 7, data: 200 }
];

3. iframe question with answerLabel parameter sends chart_data label (NOT the templated chart_data variable) e.g. https://iframe_address.com?answerLabel=chart_data
