Make charts more abstract (more general properties),

[Pilo11]

added much more options for chart labels/titles/Fonts,
added chart.JS plugin reference for chart value labels (data labels),
modified README.md

[Pilo11]

I've added much more things for options etc and a data label plugin for ChartJS (with modified README). In addition I made a base interface for the Chart objects to generalize the CanvasId and to implement an UpdateSize function for ALL charts without copying code everytime...

And some other changes, have a look at the commit changes ^^

If something is wrong with my changes please do not hesitate to contact me ^^

This is some good progress. I just had a question about the usage of GetChart(). I guess I don't understand what the usage is?

Isn't the chart object available already in the needed places?

This is ok for now. But my plan for future is that there should be a model or an extensibility endpoint so that people can write pure c# plugins and have that included with the component. I will start an issue and may be we can have more discussion about this over there.

Could you also update the test application with an example of changes as you did in the README. With that I think I will be glad to merge this!

[Pilo11]

Oh right, I will update the test project for better understanding, perhaps adding some comments here and there sould also not hurt :D

This is now merged. Thank you for the contribution. Much appreciated. Hopefully, this along with few other changes will get to the next nuget release along with Blazor updates.
