• What is the behavior you expect?
  I've expected that there'll be no seriesName before the colon inside the tooltip.
• What is happening instead?
  I don't see that tooltip yaxis title formatter works.
• What error message are you getting?
  No errors.

Fixed it, will be working in the next release.

You will need to format the tooltip.y.formatter function.

tooltip: {
  y: {
    formatter: function(val) {
       return 'val --'
    }
  }
}

@junedchhipa the formatter is still broken for x axis

This should print the dataPointIndex, however, the obj is being undefined and resetting constantly while hovering.
