Allow overriding helpers and elements

[Blazsoul]

Hi
I tried to find a way to send helpers and elements callbacks like in this 2 examples(in order to achieve rounded corners):

https://jsfiddle.net/uffo/5oty49r3/6/
https://codepen.io/jordanwillis/pen/jBoppb

Maybe there is a way but i didn't find any mention in the code.
That would be great feature

Anyway thanks for the support!

This feature is tricky because I am wary of encouraging custom Javascript (which places stress on the free servers), plus the helper functions need to be specified outside of the "chart" object context! Let me do some thinking about how to best do this.

Understood. I see how doing that as an option only requires extra computations to take place which, for a free service, isn’t helpful.

Hey @typpo thanks for open sourcing your solution. Any update on the issue above. I am trying to create a graph with a custom plugin that uses the context. I also see on issue #103 you state that QuickChart doesn't have access to your execution context.

If the issue is mainly around placing stress on the free servers, is there an option to support this on self hosted QuickChart. If so any pointers.
