在Google图表上显示空值

Question

我正在尝试使null值不可见，我正在尝试此方法，但对我不起作用，我不知道为什么错误是：

All series on a given axis must be of the same data type

[如果有人知道问题出在哪里，请帮助我，谢谢:)这是我的代码：

google.charts.load('current', {packages: ['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {

    var options = {
        title: 'Reparation par RSP',
        width: '100%',
        height: 500,
        bar: { groupWidth: "75%" },
        seriesType: 'bars',
        series: { 5: { type: 'line' } },
        colors: ['#dacfcf','#fee812','#ff7900','#ff0000','#ff0000'],
        legend: 'right',
        curveType: 'function',
        isStacked: true,

        hAxis: { format: '###' },
        titleTextStyle: {
            fontSize: 32,
        },
    };

    $.ajax({
        type: "POST",
        url: "ReparationParRSP.aspx/GetChartData",
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (r) {

            var data = google.visualization.arrayToDataTable(r.d);
            var view = new google.visualization.DataView(data);
            view.setColumns([0,
    1, {calc: function (dataTable, rowIndex) {return getAnnotation(dataTable, rowIndex, 1);}, type: "string", role: "annotation" ,sourceColumn: 1},
    2, {calc: function (dataTable, rowIndex) {return getAnnotation(dataTable, rowIndex, 2);}, type: "string", role: "annotation" ,sourceColumn: 2},
    3, {calc: function (dataTable, rowIndex) {return getAnnotation(dataTable, rowIndex, 3);}, type: "string", role: "annotation" ,sourceColumn: 3},
    4, {calc: function (dataTable, rowIndex) {return getAnnotation(dataTable, rowIndex, 4);}, type: "string", role: "annotation" ,sourceColumn: 4},
    5, {calc: function (dataTable, rowIndex) {return getAnnotation(dataTable, rowIndex, 5);}, type: "string", role: "annotation" ,sourceColumn: 5}
  ]);

  function getAnnotation(dataTable, rowIndex, columnIndex) {
    return dataTable.getFormattedValue(rowIndex, columnIndex) || null;
  }

            var chart = new google.visualization.BarChart($("#chart_div")[0]);
            chart.draw(view, options);
           // updateChart();
        },

    });

Answer 1

将此添加到您的Site.css（或您使用的任何自定义样式表。）：

#Panel1 {
  position: fixed;
  top: 0;
}

Answer 2

尝试一下

#Panel1 {
  position: fixed;
  top: 0;
  /* and any other style, such as `right`, `left`, `width` and etc. */
}
