Zoom within plot about animlib HOT 4 CLOSED

So currently updating axes + moving stuff on it works. But, problem here that we always need to re-draw the objects. Would be nice to just take what is already on the plot and zoom in. In the examples under the link they employ d3.zoom(), but it needs as event updateChart, which is similar to what I use as well. So I am not sure if employing d3.zoom an sich helps at all here...

Well, we do need to employ the zooming layout as in the link. We need clipping for stuff falling outside the plot area. Further, the zoom effect does not look all too convincing as it is now.

This seems to be a tricky deal. So far in bc20fd3 we have a trial version version where mouse wheel zoom on a scatter plot works as expected, and we can to elementary programmatic zoom. Problem, however, is that programmatic zooming is till all over the place. It seems that current version of d3-zoom does not handle this very well (see d3-zoom issue 48). There is a viable alternative in the form of external library that adds support for separating axis scales (here), see examples this and this. Might be the best approach to try this as d3-zoom v2.0 is still on its way.

Proposed solution in 1b54527; using xyzoom.js.
