Highcharts format - highcharts

Question

I am trying to work-out the format for Highcharts.
In one of the demos, there is the following call:
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=range.json&callback=?', function(data) {code to build the chart
When the call is made, data similar to the following is returned:
callback([
/* 2009-01-01 */
[1230771600000, -5.8, 0.1],
[1230858000000, -4.1, 1.4],
[1230944400000, -0.5, 4.1],
[1231030800000, -8.9, -0.7],
[1231117200000, -9.7, -3.7],
[1231203600000, -3.4, 3.2],
[1231290000000, -3.9, -0.2],
[1231376400000, -2.4, 6.7],
[1231462800000, 3.8, 6.9],
[1231549200000, 3.1, 6.8]
]);
The problem I am having is that I want to deliver the data through my own AJAX call that will have a result that will contain the graph data as well as some other things. However, I cannot seem to get the format correct so HC can read it. I read their pages about the formats, but with no luck.
I think the problem is the 'callback([]);' container needs to be removed, but when I do that, the data is not displayed in the chart.

Answer 1

i ran into the same problem once. your json has to be parsed before giving it into highcharts series
high charts series accepts an array in this format
[[float,float],[float,float]]
whereas your unparsed json would try to give
[[String,String],[String,String]]
after removing your 'callback([]);' container , you need to parse the individual '[x,y]' points before supplying it to the series object
one way of doing it(in js):
String[] jsonComponents= jsonWithoutContainer.split(",");
Iterate each of the jsonComponents array.
for each jsonComponent - String[] xyComps=jsonComponent.split(",");
x=parseFloat(xyComp[0]); y1=parseFloat(xyComp[1]); y2= parseFloat(xyXomp[2]);
put these in an array, using array1.push(x,y1) and the supply it to the chart.series(array1)

Answer 2

This callback is used for JSONP. You can simply use standard JSON to achieve that:
[[1230771600000, -5.8, 0.1], [1230858000000, -4.1, 1.4], [1230944400000, -0.5, 4.1] ... ]
Without any comments, function etc. If data would look this way, it should work.

Answer 3

Ok, I figured this out.
When jQuery loads all the data, it converts it into a string. Before it can be used by Highcharts, it needs to be converted back to an object using $.parseJSON(data).
Thanks Pawel and Austin for trying to help.
