如何在放大高图时启用y轴平移？

>您可以在Highstock中设置垂直滚动条.

yAxis: {
        scrollbar: {
            enabled: true
        }
    },

>使用基于Barbara建议的the plugin的包装代码(包含在下面),允许缩放(xy)和平移(xy).

包装代码：

(function (H) {
    H.wrap(H.Chart.prototype,'pan',function (proceed) {
        var chart = this,hoverPoints = chart.hoverPoints,doRedraw,e = arguments[1],each = H.each;

        // remove active points for shared tooltip
        if (hoverPoints) {
            each(hoverPoints,function (point) {
                point.setState();
            });
        }

        var mousePosX = e.chartX,mousePosY = e.chartY,xAxis = chart.xAxis[0],yAxis = chart.yAxis[0],startPosX = chart.mouseDownX,startPosY = chart.mouseDownY,halfPointRangeX = (xAxis.pointRange || 0) / 2,halfPointRangeY = (yAxis.pointRange || 0) / 2,extremesX = xAxis.getExtremes(),newMinX = xAxis.toValue(startPosX - mousePosX,true) + halfPointRangeX,newMaxX = xAxis.toValue(startPosX + chart.plotWidth - mousePosX,true) - halfPointRangeX,extremesY = yAxis.startingExtremes,newMaxY = yAxis.toValue(startPosY - mousePosY,true) + halfPointRangeY,newMinY = yAxis.toValue(startPosY + chart.plotHeight - mousePosY,true) - halfPointRangeY;

        if (xAxis.series.length && newMinX > Math.min(extremesX.dataMin,extremesX.min) && newMaxX < Math.max(extremesX.dataMax,extremesX.max) && newMinY > Math.min(extremesY.dataMin,extremesY.min) && newMaxY < Math.max(extremesY.dataMax,extremesY.max)) {
            xAxis.setExtremes(newMinX,newMaxX,false,{
                trigger: 'pan'
            });
            yAxis.setExtremes(newMinY,newMaxY,{
                trigger: 'pan'
            });
            doRedraw = true;
        }

        chart.mouseDownX = mousePosX;
        chart.mouseDownY = mousePosY;// set new reference for next run

        if (doRedraw) {
            chart.redraw(false);
        }
    });

}(Highcharts));

应该在图表的回调或图表的加载事件中设置起始极值,例如：

},function(chart){
        chart.yAxis[0].startingExtremes = chart.yAxis[1].getExtremes();
    });
