line non-numeric-y tooltips don't display correct values

[erikashewan]

Line graphs with a non-numeric y axis don't display the correct data values in the tooltip. They appear to just be displaying the array of the y-axis.

You can see this example in the line-non-numeric-y.html sample.

I've found a temporary fix using custom labels:

callbacks: {

label: function (tooltipItem, data) { return data.datasets[tooltipItem.datasetIndex].label + ': ' + data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index]; }

}

@erikashewan can you attach a jsfiddle test case that we can use for this?
