嗨,我從一個sqlite數據庫中使用谷歌折線圖來繪製以下數據。要清楚,有2組數據,我想繪製2行。 '沒有'的價值觀似乎混淆了這個希望,任何想法?我是JavaScript新手,只有基本的Python技能。謝謝!用不同組的x軸數據繪製谷歌折線圖
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Time', 'Temperature', 'Temperature 2'],
['2015-02-23 05:27:16', 'None', '22.88'],
['2015-02-23 05:30:02', '28.937', 'None'],
['2015-02-23 05:42:16', 'None', '23.06'],
['2015-02-23 05:45:02', '28.875', 'None'],
['2015-02-23 05:57:16', 'None', '22.94'],
['2015-02-23 06:00:02', '28.75', 'None'],
['2015-02-23 06:12:17', 'None', '22.44'],
['2015-02-23 06:15:02', '28.562', 'None'],
['2015-02-23 06:27:17', 'None', '22.19'],
['2015-02-23 06:30:03', '28.437', 'None'],
['2015-02-23 06:42:17', 'None', '21.63'],
['2015-02-23 06:45:02', '28.375', 'None'],
['2015-02-23 06:57:17', 'None', '21.13'],
['2015-02-23 07:00:02', '28.5', 'None'],
['2015-02-23 07:12:17', 'None', '21.06']
]);
var options = {
interpolateNulls: true
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
大聲笑,謝謝尼科。我沒有想過None沒有被接受爲null,並且已經添加了一些代碼,正如你所建議的那樣,所有代碼都完美無缺。謝謝 – 359 2015-03-17 20:06:48
