HighCharts Highstock每日垂直网格线在周末显示

Question

我需要在图表中为每个数据点（日）显示一条垂直网格线。在下面的jsfiddle中，您可以看到每天的垂直网格线，但问题是周末/假日显示的行（即使那些天没有数据，我使用的是有序的x轴）。有没有人知道如何在非交易日（周末/假日）禁用网格线？

你可以包装getMinorTick函数并添加条件以检查周末是否是白天。

包装：

    (function (HC) {
    HC.wrap(HC.Axis.prototype, 'getMinorTickPositions', function (proceed, points) {
        var axis = this,
            options = axis.options,
            tickPositions = axis.tickPositions,
            minorTickInterval = axis.minorTickInterval,
            minorTickPositions = [],
            pos,
            i,
            len;

        if (axis.isLog) {
            len = tickPositions.length;
            for (i = 1; i < len; i++) {
                minorTickPositions = minorTickPositions.concat(
                axis.getLogTickPositions(minorTickInterval, tickPositions[i - 1], tickPositions[i], true));
            }
        } else if (axis.isDatetimeAxis && options.minorTickInterval === 'auto') { // #1314
            minorTickPositions = minorTickPositions.concat(
            axis.getTimeTicks(
            axis.normalizeTimeTickInterval(minorTickInterval),
            axis.min,
            axis.max,
            options.startOfWeek));
            if (minorTickPositions[0] < axis.min) {
                minorTickPositions.shift();
            }
        } else {
            var today = 0;

            for (pos = axis.min + (tickPositions[0] - axis.min) % minorTickInterval; pos <= axis.max; pos += minorTickInterval) {
                today = new Date(pos)
                if(today.getDay() != 6 && today.getDay() != 0) {
                minorTickPositions.push(pos);

                }        
            }
        }
        return minorTickPositions;
    });
}(Highcharts));
