Expected behavior
Per the docs here you can use the Chart class's helpers member to perform helper function type things.
However, Chart.helpers doesn't exist when I run an npm install.
When I use the codepen link, Chart.helpers does exist. I'm not sure what the discrepancy is between
https://npmcdn.com/chart.js@latest/dist/chart.min.js and the npm version chart.js@latest but something is off.
Package.json has it listed at 3.8.0.
I copied/pasted the example code and it still wont work.
For what its worth, I am using this with ng2-charts, however a direct class import should still show the full implementation.
Curious if I'm doing something wrong.
Current behavior
Chart.helpers doesn't exist.

}
As you can see there is no helpers member on this class.
