prepostredraw

[gordonwoodhull]

Most of the time when people resort to a renderlet, they want something that fires immediately, not after the transitions. But the post* events and the renderlets deliberately fire after all transitions

dc.js/src/base-mixin.js

Line 475 in a701c49

_chart._activateRenderlets = function (event) {

Without breaking any existing code, we could maybe add more events that really trigger directly after render/redraw, with no delay, and then ppl could modify the DOM before anything hits the screen, even if they have transitions enabled.

But this has come up a million times before, it is the top gripe about renderlets.

Thanks @amergin for the link to #610.

+1 to having a postRedrawBeforeTransitionStart and keeping the current as postRedrawAfterTransitionsEnd for backwards compat.

#833 should help move this along - renderlet is just like any event now.

How about "pretransition"?

[r4j4h]

+1 for "pretransition", very succinct!

Releasing this in 2.0.0 beta 11 since it shouldn't interfere with any existing functionality.

Please try it out!

P.S. To add a transition on any added elements that runs along with the transitions on built-in elements, add it like this:

chart.on('pretransition', function(chart) {
    chart.select(...).append(...)
       // create stuff
       .transition().duration(chart.transitionDuration())
       // change stuff
