permalink or href to share the visualisation filter state

[Edouard-Legoupil]

As recommanded here(http://stackoverflow.com/questions/20853794/dc-js-permalink-or-href-to-share-the-visualisation-filter-state), i am submitting this feature request.

When users find a specific fact while they explore the data, it is not easy to reproduce the exact filters they used in order to share their findings with other users (and initiate a discussion). A solution could be to have permalinks for each filter state.

It would be great to have the capacity to freeze a certain filters state and pass it to a #href. Ideally such href would be then shared through a share button or through the regular facebook/twitter sharing function. The interface would be similar to the 'reset' button.

@Edouard-Legoupil, @cihadturhan, here is a good example you might start with:

I'd be glad to consider a pull request to make this easier, but my understanding is that it's external to dc.js and crossfilter and doesn't absolutely need any special support.

Thanks @gordonwoodhull, it actually does what I meant... It generates permalink successfully. I'll examine the code and see if it's reusable.

For a widget, I'm planning to do something like kibana plugin for elasticsearch. It shows all the filters the user applied. Here is a screenshot.

Nice!

It may not be general or directly reusable but it should give the idea.

Btw I think jQuery got a little smarter since Carlos wrote that demo. You may be able to use JQuery.param() instead of a plugin:

Another way to do this, saving the filters of all the charts on the page by index, shown in this question: http://stackoverflow.com/q/27675327/676195

Somewhat more brittle but a quick solution if the number and order of charts on the page will not change.

Regarding the Legoupil proposal, I'd prefer a solution that encodes only the changed parameters.
