Question

我想在同一页面上显示2个折线图。然而，只有一个是shwon。任何人都可以看看我做错了什么？如果我删除行chart24.draw或chart15.draw，则显示其余图表。当两者都显示时，只显示最后一个......

我的代码：

我认为这是素材图表的问题，你可以使用＆＃39; corechart＆＃39;包裹或试试这个延迟：

google.load('visualization', '1.1', {packages: ['line']});
google.setOnLoadCallback(drawCharts);

function drawCharts() {
var data15 = google.visualization.arrayToDataTable([
  ['Minutes', 'Temperature', 'Wind','Rain'],
  [1,18,0,0],
  [2,18,2.5,1],
  [3,18,0,2],
  [4,18,0,0],
  [5,18,0,2],
  [6,18,0,2],
  [7,18,0,2],
  [8,18,0,5],
  [9,18,0,0],
  [10,18,0,5],
  [11,18,0,1],
  [12,18,0,1],
  [13,18,0,4],
  [14,18,0,0],
  [15,18,5,5] 
]);

var options15 = {
chart: {
  title: 'Data of the last 15 minutes',
},          
backgroundColor: '#000000',
width: 800,
height: 300
};


var data24 = google.visualization.arrayToDataTable([
  ['Hours', 'Temperature', 'Wind','Rain'],
  [1,17,6,116],
  [2,17,4,156],
  [3,17,0,155],
  [4,17,0,108],
  [5,17,0,126],
  [6,17,53,113],
  [7,17,0,92],
  [8,17,2,99],
  [9,17,2,117],
  [10,17,5,115],
  [11,17,22,115],
  [12,18,2,115],
  [13,18,4,127],
  [14,18,8,104],
  [15,18,74,101],
  [16,19,107,79],
  [17,20,0,141],
  [18,21,27,157],
  [19,21,0,153],
  [20,21,3,110],
  [21,21,5,113],
  [22,21,10,155],
  [23,21,16,152],
  [24,20,9,109] 
]);

var options24 = {
chart: {
  title: 'Data of the last 24 Hours',
},    
backgroundColor: '#000000',
width: 800,
height: 300
};


  var chart24 = new google.charts.Line(document.getElementById('linechart24'));
 doSetTimeOutDrawChart(chart24, data24, options24, 1);
  var chart15 = new google.charts.Line(document.getElementById('linechart15'));
 doSetTimeOutDrawChart(chart15, data15, options15, 50); 

}
 function doSetTimeOutDrawChart(chart, data, options, delay){
    setTimeout(function () { 
        chart.draw(data, google.charts.Line.convertOptions(options));
    }, delay);
}
