    text
    copied!<p>I'm pulling my hairs since hours...to create multiple lines highstocks by calling php script generating the JSON data</p> <p>I've a php/javascript file that downloads JSON data containing 2 series. <a href="http://nas.parvais.com/domotique/sonde_exp_json.php?sonde_id=24&amp;callback=a" rel="nofollow">look here</a> </p> <p>Then, in my <a href="http://nas.parvais.com/domotique/chart_sonde.php?sonde_id=23" rel="nofollow">php file creating the highchart</a>, I've the following code to display graph of a probe ($sonde_id): <a href="http://jsfiddle.net/tparvais/bYPQc/" rel="nofollow">see fiddle</a>: the first serie "average" is with the average value, the second is a range with min/max. I can scroll over the time/zoom etc... the refresh works. This is very slow for another known problem, but it works.</p> <p>Now my problem us that I'd like to display multiple lines from different probes ($sonde_id).</p> <p>I tried the following code for charting probe 23,22 &amp; 24; by simply multiplying the json.get but that does not work </p> <pre><code> var url = 'sonde_exp_json.php?sonde_id=23&amp;callback=?' ; $.getJSON(url, function (json_data_23) { console.log (json_data_23.average); options.series[0].data=json_data_23.average; }); //end getJSON url = 'sonde_exp_json.php?sonde_id=22&amp;callback=?' ; $.getJSON(url, function (json_data_22) { options.series[1].data = json_data_22.average; }); //end getJSON url = 'sonde_exp_json.php?sonde_id=24&amp;callback=?' ; $.getJSON(url, function (json_data_24) { options.navigator.series = json_data_24.average; options.series[2].data = json_data_24.average; }); //end getJSON </code></pre> <p>error is "ncaught SyntaxError: Unexpected identifier " after the line options.series[0].data.=json_data_23.average;</p> <p>I don't understand the problem. I'm totally lost with these objects/arrays/json and structure to display multiple lines on same charts. I read many others answers, but I miss something</p> <p>Thank you</p>
