add support for time series

[timelyportfolio]

As you can probably tell, I am very interested in this. If ok, can we add this issue to track progress on the quote from Readme.md?

does not really take advantage of metricsgraphics' best feature - time series charts

@jjallaire might have some ideas here and think it would be very good to leverage the infrastructure with xts provided by rstudio/dygraphs lines especially given some of the complexities already discovered with things such as time zones rstudio/dygraphs#16 and date formats rstudio/dygraphs#21 .

Happy to close if you think not helpful.

Def keep the issue. I was going to "borrow" much of the xts goodness from the widget-ized dygraphs. I actually want to add far more intelligence into the whole pkg. Pick better defaults for size based on chart type (and data size). Auto-assign decent colors, etc.

do you want to add an issue for these additional features or maybe add a Todo.md?

basic time series support is in there now. it relies on setting mjs_axis_x(xax_format="date"). i'm keeping this open until i get support in for xts, etc.

This is shaping up very, very nicely! So excited to see this come together.
BTW feel free to take whatever you need of the xts code in dygraphs :-)
