Question

我想在放大图表时移动Y轴现在我可以在缩放时移动X轴

Bellow是用于平移的代码

chart: {
        renderTo: 'container1',
        type: 'column',
        zoomType: 'xy',
        panning: true,
        panKey: 'shift',}

任何帮助将不胜感激

可能的解决方案：

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, false, {
                trigger: 'pan'
            });
            yAxis.setExtremes(newMinY, newMaxY, false, false, {
                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：

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

Y轴平移不是内置于HighCharts中的。但是，有一个插件可以解决问题：http://www.highcharts.com/plugin-registry/single/27/Y-Axis%20Panning 这些例子表明它与highStock一起使用，但它与highCharts同样适用。

如何在放大高图时启用y轴平移？
