How can I fix Highcharts error #13?

Question

I use highchart so, the user can close and open the chart page and redraw the chart, in some case give me this error, how can I fix it, Thanks Here is my code

Answer 1

Categories needs to be a collection, it was like this:

categories: xaxis

Change it to this:

categories: ['xaxis']

Some of the data fields need to be enclosed in single quotes like this:

data: 'blue'

Here is a fiddle without any errors for you:

Good luck with the rest. :)

ps I sometimes find it easier to edit a working fiddle from the highcharts site and adapt it to what you need. Like this one:
