d3.behavior.zoom jitters, shakes, jumps, and bounces when dragging
- by BrettonW
I am using the d3.behavior.zoom to implement panning and zooming on a tree layout, but it is exhibiting a behavior I would describe as bouncing or numeric instability. When you start to drag, the display will inexplicably bounce left or right until it just disappears. The code looks like this:
var svg = target.append ("g");
...
svg.call (d3.behavior.zoom()
.translate ([0, 0])
.scale (1.0)
.scaleExtent([0.5, 2.0])
.on("zoom", function() {
svg.attr("transform","translate(" + d3.event.translate[0] + "," + d3.event.translate[1] + ") scale(" + d3.event.scale + ")");
})
);
Am I doing something wrong?
