Simplify the building of a chart

[JustSteveKing]

Currently there are 20 odd props available on the Chart component itself, while this is ok because you can use the ones you want - it wuold be nice to investigate a cleaner way to do this.

Perhaps having directives for each chart that you actually want to use would be cleaner - keeping props to general meta information required across all charts?
