How to use Data Structures in Floating Bar Chart?

[Udemology]

I am currently struggling with Data Structures in a Floating Bar Chart.

I am familiar with Data Structures. But I could not figure out how it would work specifically for the floating bar chart.

For example my Data Structure is like this.
data: {start: 10, end: 15, task: 'build a function'}

How would I be able to specify this on the x-axis specifically the start and end value? Is this possible as of now?
I tried to place it in an array similar to the primitive style that the floating bar chart uses. But it only selects the first value and does not float.

Like this:
options: { parsing: { xAxisKey: 'task', yAxisKey: ['start', 'end'], }, }

Is it possible to use?

This is not supported. The code expects just a single string as input for the yAxisKey. The way the object gets checked can be seen here:

Chart.js/src/helpers/helpers.core.js

Lines 303 to 315 in 838d40b

	export function resolveObjectKey(obj, key) {
	if (key === emptyString) {
	return obj;
	}
	let pos = 0;
	let idx = indexOfDotOrLength(key, pos);
	while (obj && idx > pos) {
	obj = obj[key.substr(pos, idx - pos)];
	pos = idx + 1;
	idx = indexOfDotOrLength(key, pos);
	}
	return obj;
	}

So you will need to have your floating config already in the object like so:

data: [{test: 'a', tt: [5,3]}, {test: 'b', tt: [0,4]}, {test: 'c', tt: [-3,9]}]

EDIT:
Looked bit more into it and for the parsing it indeed only looks the value up once but it seems like even if you pass an array, the moment the options resolver object is being made the array you passed to the yAxisKey get changed to just the first element of it

Hi Leenelaleee, thank you for your answer. I manage to get it to work based on your example. Just a question before I accept the answer.

I have never heard of the "options resolver object". I suspect this has to do with the options object but I cannot fathom what it is or when it would apply. Is there a reference in documentation about the "options resolver object" or anywhere else so I grasp the concept of what it is?

After reading the function name I realize the function itself is the resolver object. Sorry about that. Thank you for helping out. Truly appreciate it.
