Custom x and y accessors

[esbullington]

We've been kind of assuming people will use x and y as the names of their respective data names, which is pretty inflexible. We should probably let them specify a custom x and y accessor. So, they could do something like:

<Chart x_accessor="event_dates" y_accessor="event_values" />

And then instead of using point.x and point.y, we'd use point.[props.x_accessor] etc.

Does this sound reasonable?

Yeah this sounds true. Same thing for label and value too ?

[esbullington]

Done for x and y accessors. I'm still thinking about label and value accessors.
