Google柱形圖缺少數據

Question

我已經搜索了很多時間，但是沒有找到任何可行的解決方案，因此決定提出一個問題。 為什么我看不到我的firs data_row元素99.00日期？

這是代碼，我如何初始化所有腳本：

var colors = [ '#F1A504', '#80CE61', '#0BA3E4', '#7E4CCF' ];
var gChart = {
    table_data : {
        1: 'Reguliavimas "į viršų" kiekis',
        2: 'Reguliavimas "žemyn" kiekis',
        3: 'Reguliavimas "į viršų" kaina',
        4: 'Reguliavimas "žemyn" kaina'
    },
    data_row : [
        [ new Date( 2013, 3, 17, 0, 00, 00 ), 0.00, 99.00, 0.00, 40.00],

    lang : 'lt',
    maxV : 108.00,
    minV : 0.00,
    chartType: 1,
    dataGroup: 'H'
};


function drawChart( id, table_data, data_row, lang, chartType, colors ){

var dataTable = new google.visualization.DataTable();

dataTable.addColumn('datetime', 'Time');
for ( var i = 1; i <= objCount( table_data ); i++ ) {

    dataTable.addColumn( 'number', table_data[i] );
}

var dataView = new google.visualization.DataView( dataTable );


var options3 = {
    width: 670,
    height: 380,
    fontSize: 11,
    colors: colors,
    backgroundColor: 'transparent',
    legend: 'none',

請在未顯示第一列的Google可視化圖表中查看我的答案

本質上，您需要使用DataView將表的第一列設置為字符串格式。

后：

var dataView = new google.visualization.DataView( dataTable );

插入：

dataView.setColumns([{calc: function(data, row) { return data.getFormattedValue(row, 0); }, type:'string'}, 1, 2, 3, 4]);
