[Chartjs]-Add a text as tooltip for each point on a line chart

The way i added my custom tooltips.
Firstly i created a dataset in which data array i added additional info like “count”

x: 10,
y: 12,
count: 2

This count does not get shown in graph unless I manually get it in options hook under tooltips.

tooltips: {
      callbacks: {
                label: function(tooltipItem, data) {
                    return i18n.t('chart.count') +': ' + getCount(tooltipItem, data.datasets);
                }
      }
 }

Get count for given dataset that was not represented in chart

function getCount(tooltipItem, datasets) {
    return datasets[tooltipItem.datasetIndex].data.find(datum => {
        return datum.x === tooltipItem.xLabel && datum.y === tooltipItem.yLabel;
    }).count;
}

And the result:

Edit: adding an example of my dataset

return [{
    label: 'Example dataset',
    backgroundColor: '#98cc99',
    borderColor: '#98cc99',
    pointHoverRadius: 3,
    data: [ {x:1,y:2,count:3}, {x:2,y3,count:4}, ...]
}];
