Touch-scrubbing across sparkline

[jdonald]

Happy to see this project. There are a number of usable Sparkline web components in React or Polymer, but until now this seems like an area lacking in React Native.

Is there a mechanism for touching the sparkline and highlighting the corresponding point, similar to this React web example with hover-scrubbing:

Or as built in to Robinhood's open-source spark library for Android:

Is such a feature within the scope of this project?

Yes, we'll support this feature in the future.
