Question

I got this error : "Uncaught TypeError: Cannot assign to read only property 'color' of [..."

I got the ajax data set but when I want to draw Pie it gives mentioned error, interesting part is that when I remove the color it also gives same error with 'color' keyword again. I can draw pie with static values, when use ajax get this problem.

According to their sample page

Keys for data elements are not supposed to be wrapped in in single quotes.

You should return JSON data like this:

var data = [
    {
        value: 8.9,
        color:"#F7464A",
        label: "Jurasic Park"
    },
    {
        value: 8.1,
        color: "#46BFBD",
        label: "Saving Private Ryan"
    },
    ...
];
