空点highcharts / highstock

Question

我有一组不规则的空数据，但我无从知晓。 有没有办法在图表上突出显示它们？

示例：http://i.stack.imgur.com/fzZ4f.jpg

我使用xAxis: {ordinal: false}作为图表行，但我需要突出显示空点，例如：http://i.stack.imgur.com/xTZbZ.jpg

在该系列中，缺少点，并且不会收到零点。我不能设置为null。带图表的代码脚本：

// Example data:
data = [[x1,y1],[x2,y2],[x6,y6]]; // x3,x4 and x5 are missing.

function changeData(min, max) {
    var chart = $('#{{div_id}}').highcharts();
    chart.showLoading('Actualizando datos...');
    var params = {type:'{{type}}', id: '{{id}}', from: min, to: max};
    $.post("{{url('dashboardmetric')}}", {metric: 'getDataGraphMetric', params: params},
    function(data) {
        $.each(data, function(i, v){
            chart.series[i].setData(data[i], true);  //Seteo de datos de la serie
        });
        chart.hideLoading();  //Se libera el bloquero
    }, "json");
}

$(function() {
    Highcharts.setOptions({ 
        lang: {
            months: ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio', 'Julio', 'Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre'],
