events triggering the render of more than one Mark?

[Pedro Alves]

Hey there

From the samples I know that we can choose what to render as a result
of an event by returning that object.

Can we do that for more than one? I'm currently doing a global
vis.render() but I guess that's not very effective if all I want is to
change properties of a line and a dot, for instance

thanks

At the moment it takes a bit of trickery to re-render  only one mark. If you search the list you'll probably find Mike having mentioned how to do it a few times.

I believe one of Mike's tasks at the moment is to find a nicer way of dealing with interaction.

Alternatively, you could access the SVG DOM after rendering and manipulating them directly. This'll tie your interaction to the protovis version + your graph, but from the SVG I've read, wouldn't actually be that hard (or horrible).

I haven't yet needed to do anything in this space so I've no specific suggestions sorry.
