I am not sure what you are asking regards to the legend. Your jsFiddle is showing a legend - you only have one series "Series 1" and it is in the legend. To display the value of each waterfall you need to use the correct plotOptions:

plotOptions: {
  waterfall: {
    dataLabels: {
      enabled: true,
      crop: false,
      inside: false,
      overflow: 'none'
    }
  }
},
