Interactive pan/zooming

[jimhester]

I feel like ggvis would really benefit from supporting interactive pan and zooming ala gadfly.

Do you currently have any plans to support these types of simple interactions with ggvis, I have not seen any of this functionality in the current demos.

I would be happy to do submit on a pull request if you think it is feasable to do with vega (it does not look like it is implemented in vega currently https://github.com/trifacta/vega/issues/168).

Also I really like the new syntax, being able to use %>% in both dplyr and ggvis makes for a very nice workflow.

It's definitely something we want to add. I think changing the domain of vega scales would be the most natural way to do this, but they're currently static and can't be updated easily (or at least don't have a good exposed API). If you have ideas on how to implement, we'd love to hear them.

It is possible now to zoom and pan - if you show the zoomed and panned results in a second plot.

Before you dig to deep into the code, please bear in mind that there are major changes coming - we've been working on the new-syntax branch, which has big changes to the API, as well as a much simpler way of creating interactive components.

Closing now that you can supply reactives to scale domains.
