How do I add dynamic data to apexcharts using vue.js? - vue.js

Question

I am trying to use dynamic data in my donut apexchart, but I don't know the correct way to do it.
I tried setting "test: 5" under data and then change the static number in series: [this.test, 4, 1]. Did not output anything, I am new to programming.
<script>
import VueApexCharts from 'vue-apexcharts'
export default {
name: 'Dashboard',
components: {
apexcharts: VueApexCharts
},
data () {
return {
test: 6,
series: [this.test, 5, 4],
chartOptions: {
plotOptions: {
pie: {
donut: {
labels: {
show: true,
name: {
fontSize: '24px'
},
value: {
fontSize: '34px',
color: '#fff'
}
}
}
}
},
tooltip: {
enabled: false
},
legend: {
show: false
},
fill: {
colors: ['#4b367c', '#2aa5ed', '#db2828']
},
dataLabels: {
enabled: false
},
labels: ['Utkast', 'Öppen', 'Förfallen'],
colors: ['#4b367c', '#2aa5ed', '#db2828']
}
}
},
mounted () {
this.$store.commit('setPageTitle', { title: 'Översikt' })
}
}
</script>
My goal is to reach in to firebase and use the data from there, but to start with I just wanted to test out how to add any data and failed here already.

Answer 1

You should not use one variable in another directly in data.
series: [this.test, 5, 4],
This will return null in this.test.
You can set series empty intially and set values later.
series:[]
And then populate series in some function.
Or else use computed() as follows:
computed: {
series() {
return this.test;
}
}

Answer 2

You can update the chart data dynamically like this.
this.chartOptions = {labels:['dynamic data here']}
this.series = ['dynamic data here']
