Chart won´t load using json

[abcdef]

I try to load a chart with json using

    mychart.load(url, "json");

but got an XML parsing error. My web server log shows:

[{“sla”:“100”,“color”:“#00ff00”,“id”:1},{“sla”:“91.52”,“color”:“#00ff00”,“id”:2},{“sla”:“92.37”,“color”:“#00ff00”,“id”:3},{“sla”:“95.58”,“color”:“#00ff00”,“id”:4},{“sla”:“91.3”,“color”:“#00ff00”,“id”:5},{“sla”:“100”,“color”:“#00ff00”,“id”:6},{“sla”:“100”,“color”:“#00ff00”,“id”:7},{“sla”:“94.44”,“color”:“#00ff00”,“id”:8},{“sla”:“98.72”,“color”:“#00ff00”,“id”:9}];

So everything seams OK but won´t work. If I try load an XML everything is OK.

What´s wrong with my json or with my code???
