Mouse-wheel moves timeline only in one direction

To get mouse move I added
var origin =evt.pageX;
to get mousedown point
On mouse up did
var moveto =evt.pageX;
and
delta=(origin-moveto);

But I had prolems when range blocks started outside the zoomed in area - and found a D3 project that sorts it out with an SVG based build.
