highcharts not plotting json string containing x,y pairs (string, float). how to fix? - highcharts

Question

I just switch from jqplot to highcharts, because i couldn't find an answer for my problem with jqplot.
My problem:
I want to plot the following result from a json string. this string contains out of datapairs in the following format: yyyy00kw (year with 4digits, 00 for padding, weeknumber 2digits) and a value (could be formated to float).
because the x value of the pair could change to yyyymmdd (year month day) or yyyywwdd (year week day) it has to be a string.
My json string contains the following:
[

Here is my javascript code:
<script class="code" type="text/javascript">
var data = [];
var chart;
$(document).ready(function() {
//hier geht es los
$.getJSON("120925_sql_bauen.php", function(json) {
chart = new Highcharts.Chart({
chart: {
renderTo: 'chart1',
type: 'line'
},
title: {
text: 'Wetterdatenprojekt'
},
xAxis: {
//categories: []
},
yAxis: {
title: {
text: 'aktuelle Wetterwerte'
},
plotLines: [{
value: 0,
width: 1
}]
},
series: json
});
});
});
</script>
Unfortunately highcharts shows no plot.
I hope, that highcharts doesn't have the same problem with strings then jqplot :-(

Answer 1

The problem is that you try to use your reply directly. You need to "remove" one layer of arrays. That is data should be json[0]
I updated my example: http://jsfiddle.net/GgNmY/2/
Regarding previous note that values should be numeric is only true for Y-axis (at least in earlier versions of Highcharts).
Edit: Here is to extract the data point (the values) and the categories.
var data = [];
var cats = [];
json[0].forEach(function(point){
data.push(point[1]);
cats.push(point[0]);
});
Here is an running example: http://jsfiddle.net/GgNmY/3/

Answer 2

In Highchart, you can set your series : data object in the form of the JSON input.
In such a case, if the JSON input is in the form:
[
[1,12],
[2,5],
[3,18],
....
[10,22]
]
Then the following attribute can be added in the chart definition:
series:[{
data: json
}]
Here is the running JSFiddle example
