Using Percent Sign in Scale

[simonferndriger]

This is either a bug report or feature request, depending on the answer to this problem.

I looked up the documentation to use the % in my y-scale. There is a link/reference to http://www.chartjs.org/docs/#scale-title-configuration
Unfortunately, there is no content under this address.

So, someone, please tell me how to do this with the current version (since all examples I found on StackOverflow don't work anymore).

Thank you!

@simonferndriger this is a bug in the documentation that that link doesn't work. If you search in the page, the section exists though.

Are you wanting the '%' on each tick mark or on the axis title?

[simonferndriger]

Both would work for me. However, on each tick would be my first choice!

@simonferndriger you can do

options: {
  scales: {
    yAxes: [{
      ticks: {
        callback: function(tick) {
          return tick.toString() + '%';
        }
      }
    }]
  }
}

@etimberg Thanks! It works :) However, I would have thought that there could be a more intuitive way to do something rather common like this (choosing the scale unit), but it's fine for me.
