Adding a node via clicking about jquery.flowchart

Sorry for my late answer. Just a question, do you get the positioning correctly when panzoom is disabled (or no zoom in the image). Because if it doesn't work correctly when zoomed in / zoomed out, check out the code of the last example, notably:

    var possibleZooms = [0.5, 0.75, 1, 2, 3];
    var currentZoom = 2;
    $container.on('mousewheel.focal', function( e ) {
        e.preventDefault();
        var delta = (e.delta || e.originalEvent.wheelDelta) || e.originalEvent.detail;
        var zoomOut = delta ? delta < 0 : e.originalEvent.deltaY > 0;
        currentZoom = Math.max(0, Math.min(possibleZooms.length - 1, (currentZoom + (zoomOut * 2 - 1))));
        $flowchart.flowchart('setPositionRatio', possibleZooms[currentZoom]);
        $flowchart.panzoom('zoom', possibleZooms[currentZoom], {
            animate: false,
            focal: e
        });
    });

You need to set the position ratio...
