ticks formatting

[saurabh-bhosale]

How do i use javascript userCallback for ticks in rails format?

I found that you can pass the callback method as a string and it put into the template as JS that executes

e.g.

<%= line_chart data, {scales: {yAxes: [{ticks: {callback: "function(value, index, values) { return value + '%'; }"}}]}} %>

@adampope in tooltips callbacks also work. thx
