First I have PhantomJS Webserver with HighCharts 3 running great, it produces charts extremely fast.
In the following code you'll notice I'm trying to add "this.name" in the $legend value.
For whatever reason everything works great until I try to concatenate dynamic HighCharts this.name.
Statically the code works great and if I comment out $legend the chart looks great.
In the $legend value example below you'll see where I'm trying to escape the double quotes.
Any help is appreciated thanks...
