Enhancement Request - Hide Legend Per-Dataset

See original GitHub issue

Current it is easy to remove the legend from charts via the global or chart level config options. However, it would be very useful for me to be able to remove the legend on a per-dataset level.

Currently:

options: {
    legend: {
          display: false
    }
}

Requested API:

var lineChartData = {
    labels: [],
    datasets: [{
        label: '',
        data: [],
    }, {
        data: []
        legend: false,
    }]
}

v2.7.0

Under options, add the following:

options: {
  legend: {
    labels: {
      filter: function(legendItem, chartData) {
      
        // return true or false based on legendItem's datasetIndex (legendItem.datasetIndex)
      }
    }
  }
}

Angular\Typescript:

options: {
  legend: {
    labels: {
      filter: (legendItem, chartData) => {
      
        // return true or false based on legendItem's datasetIndex (legendItem.datasetIndex)
      }
    }
  }
}
