BarLabels for Column Charts

[akshayakrsh]

Is there a way to change the figure displayed on the bars of a column chart? E.g. if my data object looks like:

var dataObj = [
{ x : '2010', y : 5 },
{ x : '2011', y : 15 },
{ x : '2012', y : 20 },
{ x : '2013', y : 0 },
{ x : '2014', y : 0 },
];

Then instead of showing "0" for x = 2013/2014 I want to show "-" on top. Possible?

Yes it is, all you want to do is something like this:

chart
.using('barLabels', function(label) {
    label
    .text(function(d) {
        if(+d[this.valueKey] < 1){
            return '-';
        }else{
            return d[this.valueKey];
        }
      });
  });

Yup, works like charm! Probably should add it in the documentation somewhere.

Yes, I think I'll need to stop adding features soon so that I can catch up on documentation :-(
