Highcharts-Vue wait for data then update series

Question

There seems to be a few examples of how to do something similar, but all slightly different from my case. I am loading some stock data from an API (in a JS file) and then using it in my VUE. I would like to update my chart series with a new array compiles from the API data, but it's not working and I am not getting any errors.

My Vue looks like this:

<template>
    <div>
        <highcharts :options="chartOptions" :updateArgs="[true, false]" ref="highcharts"></highcharts>
    </div>
</template>

<script>
    import appService from '../stock_prices'
    import {Chart} from 'highcharts-vue'

    export default {
      name: 'stocks',
      props: {
        msg: String
      },
      data () {
        return {
          chartOptions: {
              mySeries: [],
              info: {},
              updateArgs: [true, true, true],
              series: [{
                  data: [1,2,3,4,5,6,7]
                }],
             }
          }, 
        }
      }, //data

      components: {
        highcharts: Chart 
      },

      methods: {
        updateSeries() {

          for (var i = 0; i < this.info.stock_prices.length; i++) {
          this.mySeries.push([this.info.stock_prices[i].volume]);
          i++
          } 


          data: this.mySeries

        }
      }, //methods

      async created () {
        this.info = await appService.getPosts();
        this.updateSeries()
      }, //async created

} //export default

I would like to obviously wait for all my data from my API (in the appService component) to load and then use it to create the updated series, but I am not sure that is actually what is happening.

Perhaps an important note: If I replace data: this.mySeries in my method with something like data: [10,10,10,10,10,10] it is still unsuccessful - no errors and the series is not being updated.

Thanks!

Notice, that your data doesn't contain chartOptions. Also, in updateSeries() you are updating data which refers to nothing. It should be something like the example below:

<template>
    <div>
        <highcharts :options="chartOptions" :updateArgs="[true, false]" ref="highcharts"></highcharts>
    </div>
</template>

<script>
    import appService from '../stock_prices'
    import {Chart} from 'highcharts-vue'

    export default {
      name: 'stocks',
      props: {
        msg: String
      },
      data () {
        return {
          mySeries: [],
          info: {},
          updateArgs: [true, true, true],
          chartOptions: {
            series: [{
                data: [1,2,3,4,5,6,7]
            }]
          }
        }
      }, //data

      components: {
        highcharts: Chart 
      },

      methods: {
        updateSeries() {
          for (var i = 0; i < this.info.stock_prices.length; i++) {
            this.mySeries.push([this.info.stock_prices[i].volume]);
          } 

          this.chartOptions.series[0].data: this.mySeries;
        }
      }, //methods

      async created () {
        this.info = await appService.getPosts();
        this.updateSeries()
      }, //async created

} //export default
