    text
    copied!<p>I have a 2 arrays which I got from php, put into a single 2D Javascript array. I'm trying to use it to autofill a Google Chart DataTable, but so far I've had no success. The only thing that I can think of is that maybe the array ix MxN dimension, while the function needs a NxM array?</p> <p>Either does it not work because the first array is made of numbers?</p> <pre><code> &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head&gt; &lt;meta http-equiv="content-type" content="text/html; charset=utf-8" /&gt; &lt;title&gt;Pressure Monitor&lt;/title&gt; &lt;script type="text/javascript"&gt; var samptable = new Array(); samptable[0] = new Array(2); samptable[0,0]= nbsamples; //first array obtained from php samptable[0,1]= samples; //second array obtained from php. both are merged into a 2d array &lt;/script&gt; &lt;script type="text/javascript" src="http://www.google.com/jsapi"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; google.load('visualization', '1', {packages: ['corechart']}); &lt;/script&gt; &lt;script type="text/javascript"&gt; //var data; function drawVisualization() { var data = google.visualization.arrayToDataTable(samptable[0]); // Create and draw the visualization. new google.visualization.LineChart(document.getElementById('visualization')). draw(data, {curveType: "function", width: 500, height: 400, vAxis: {maxValue: 10}} ); } //function draw(){ //} google.setOnLoadCallback(drawVisualization); &lt;/script&gt; &lt;/head&gt; &lt;body style="font-family: Arial;border: 0 none;"&gt; &lt;div id="visualization" style="width: 800px; height: 400px;"&gt;&lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>The code used to get nbsamples and samples:</p> <pre><code>echo '&lt;script type="text/javascript"&gt;'; echo 'var samples = new Array("', join($ydata,'","'), '");'; echo 'var nbsamples = new Array("', join($nbsamples,'","'), '");'; echo '&lt;/script&gt;'; </code></pre>
