Laravel Charts - Trying to change ChartJS data dynamically fails

I'm using Laravel 6, Laravel Charts along with ChartJS. I have succesffully rendered a chart.

Laravel gives it a random unique ID each time the page is loaded.

I get it like so:

{{ $pieGenderChart->id }}

I wan't to change some of the dataset dynamically so I've looked into the DOM with

console.log(window);

Here's my chart (I believe)

I want to be able to change the data in the dom like so:

window.{{ $pieGenderChart->id }}.config.data.datasets[0].data[0] = x

It sits in the root of window... so I should be able to call it like so, right?

console.log(window.{{ $pieGenderChart->id }}); 
console.log(getElementById({{ $pieGenderChart->id }}));

Either way, same with JQuery, I only get the following

What am I missing here?
