php - Use array data in highcharts - Stack Overflow|江阴雨辰互联

I'm trying to display a chart with highcharts. I have a 2-dimension-Array with values for Inductance and Current. How can I use that data to display a chart? I was looking for it, but I didn't find the correct answer... In the highcharts demos there are only cases wich you write directly the values, but never use an Array. I'm using html+php+javascript in my web page. If someone could help me, I would appreciate so much.

Thanks in advance and best regards.

P.S: If someone knows another way to display charts easier, I also would appreciate.

EDIT:

Thanks for answer. I think that I don't understand so well this library... I will post my code

//I initialize the array with the name Array_L_I_XXXX with the results from my SQL query
while($row4 = mysqli_fetch_array($result3))
{
    $Array_L_I_XXX[j][0] = $row4['L_value'];
    $Array_L_I_XXX[j][1] = $row4['I_value'];

        $j++;
    }     
 echo "<div style=\"margin: 0 1em\">";
 echo "<script src=\".js\"></script>";
 echo "<script src=\".js\"></script>";

 echo "<div id=\"container\" style=\"min-width: 400px; height: 400px; margin: 0 auto\"></div>";

Also, in the <head> part, I have the following code

    <script type="text/javascript">
     var chart = new Highcharts.Chart({
         chart: {
            renderTo: 'container'
         },
            series: [{
            data: [<?php echo join($Array_L_I_XXX, ',') ?>],
            pointStart: 0,
            pointInterval
         }]
   });
</script>

That doens't work (for sure is so wrong...) but really I can't find the correct way to do this... Thanks!

I have my 2D-array in php Array_L_I[X][Y], and now, I insert the following code to call the highchart function:

echo ""; echo ".js\">";
```
echo "<div id=\"container\" style=\"min-width: 400px; height: 400px; margin: 0 auto\"></div>";
```
- In the <head> section I have the code Highchart conde

My problem is that I don't know how to "send" this array to the highchart function to use my values (It is not like a js function that I can send some variables...)

Thanks in advance and best regards.

I don't understand your question. Highcharts accepts data in the following formats: api.highcharts./highcharts#series.data. These are of course javascript datatypes since Highcharts is a javascript product. So, are you asking how to convert your 2d PHP array to a 2d javascript array? – Mark Commented Jun 27, 2013 at 15:38

Without much details, I'll assume you are returning a PHP array and need to convert it into a JS array for use in HighCharts:

<script type="text/javascript">
    js_array = new Array(<?php echo implode(',', $php_array); ?>);
</script>

HighCharts:

series: [{
        data: js_array
    }]

Follow this basic example and you can fine tune it for your project.

Please take look at article about bine php array and Highcharts.
