Trying to connect the scroller of either chart so that when you scroll on one chart it also scrolls on the other.

As far as I can understand, the ‘stock’ chart available from anychart has access to the ‘setRange’ functionality – however I need to use the Box charts and cannot find an alternative

    var stage = anychart.graphics.create('container');
    var chart_stage = anychart.graphics.create('container-chart');
    var chart_stage2 = anychart.graphics.create('container-chart-2');

    var chart1 = anychart.box();
    chart1.data(testdata);

    chart1.container('chart1');
    chart1.xScroller(true);
    chart1.container(chart_stage).draw();

    var chart2 = anychart.box();
    chart2.data(testdata);
    chart2.xScroller(true);
    chart2.container('chart1');
    chart2.container(chart_stage2).draw();

    var scroller = anychart.standalones.scroller();
    var scroller2 = anychart.standalones.scroller();
    scroller.parentBounds(10, 0, 400, 60);
    scroller2.parentBounds(10, 100, 400, 60);

    // Set range.
    scroller.setRange(0.1, 0.5);
    scroller2.setRange(0.1, 0.5);


    scroller.container(stage);
    scroller2.container(stage);

    scroller.container(stage).draw();


    scroller2.draw();

    function synchronizeScrollers(sourceChart, targetChart) {
        sourceChart.listen('scrollerchange', function (e) {
            console.log(e);
            scroller.setRange(e.startRatio, e.endRatio);
            chart2.setRange(e.startRatio, e.endRatio);
            e.startRatio = 0;
            e.endRatio = 0.1;
        })
    }

    synchronizeScrollers(chart1, chart2);
