Suggestion: Add stroke options for Pie & Doughnut charts

[troywarr]

This appears to be possible with v1.x, but it does not appear to be supported in v2.x (at least it's not apparent from the docs - I've tried every iteration of options that I can imagine).

Specifically, a current project of mine requires a pie chart with no gaps between sections:

The applicable option from v1.x would be segmentShowStroke, but segmentStrokeColor and segmentStrokeWidth also seem apropos. Docs here:

http://www.chartjs.org/docs/#doughnut-pie-chart-chart-options

If necessary, I can use v1.x for the pie chart alongside v2.x for the other chart types I'm using, but it would be ideal to get it all done with v2.x.

Thanks!

@troywarr the v2 docs are at http://nnnick.github.io/Chart.js/docs-v2/ until @nnnick can get the site updated.

There are 2 ways to turn off the borders.

You could set the border width to 0 for all arcs by adding the snippet below to your config

elements: {
  arc: {
    borderWidth: 0
  }
}

you could also add borderWidth: 0 to your dataset. I created https://jsfiddle.net/j9a1979b/ for you

@etimberg Thanks so much for the quick and helpful reply! I throughly appreciate the JSFiddle example - that cleared it right up.

FWIW, I had spent some time with the v2 docs but still missed this option. There's a lot of information in the docs, and in hindsight I was able to locate where this was mentioned, but I think something centralized like a terminology glossary or a chart anatomy diagram (labeling the components of each chart type) could go a long way. I'll try to find some time to contribute to something like that via PR.

Thanks again!

@troywarr glad I could help.

Good call on the docs terminology section. I'll be more than happy to merge a PR updating the doc files
