Add prefix and suffix for when formatter is undefined

Is your feature request related to a problem? Please describe. In ApexCharts.rb, the way we configure options is with ruby hash converted to JSON. We have no way to specify, e.g. formatter: function(val) { return "Rp " + val + "-" }. Function is a valid value for JS object but not for JSON.

Describe the solution you’d like I’d like to propose prefix and suffix. So, instead of specifying formatter above, we can do this:

prefix: "Rp ",
suffix: "-",

It’s a valid key-value for JS object and JSON too. So we can specify it from ruby hash. prefix and suffix should be checked only when formatter is undefined.

Hi @styd, Sorry, I have been very busy with other things lately, and this issue went unnoticed from my list. I have added additional tags to this issue to keep reminding myself to work on it soon. Thank you for your patience.

How about this approach?

var fnObj = {"function":{"arguments":"a,b,c","body":"return a*b+c;"}}
var fn = new Function(fnObj.function.arguments, fnObj.function.body);

This will require a minimal change in apexcharts lib.
