Changing drilldown series data dynamicly does not work about highcharts-vue HOT 3 CLOSED

Thank you for reporting the issue.
Unfortunately, it's not a bug at all and that's only the effect of incorrect way of implementation, so I'll try to explain you why it's happening.

First of all, you defined the data parameter inside of your series just like that:

series: [{
    data: [{y:10, drilldown:'first'}, {y:0, drilldown:'second'}, 8, 2, 6, 4, 5, 5],
    color: '#6fcd98'
}],

So, on first chart render, your drilldowns works fine, but let's try to deduce what happening if you're trying to change any number in input field.
There is the watch function assigned to points component data element (which is actually an array of numbers), and it assigns the newValue to the chartOptions.series[0].data, so basically at this level of process you can see what is happening with your initially set data. It has been overridden by new data value without drilldown field.
In order to fix that, first you need change the definition of points component field, so that it would be an array of objects, and then change the way of modeling the data, just like that:

points: [{y:10, drilldown: 'first'}, {y:0, drilldown: 'second'}, {y:8}, {y:2}, {y:6}, {y:4}, {y:5}, {y:5}],

        <form class="row points">
          <div v-for="index in 8" :key="index">
            <p>{{index}}</p>
            <input v-model.number="points[index-1].y" type="number" class="numberInput">
          </div>
        </form>
