Put array in chart data - vue.js

Question

I use vue3-chart-v2 in my Vue3 app.
I would like to put array instead of predefined numbers.
Can anybody help me?
This is my chart component:
<script>
import { defineComponent } from 'vue'
import { Line } from 'vue3-chart-v2'
export default defineComponent({
name: 'ChanceChart',
extends: Line,
props: {
chartData: {
type: Object,
required: true
},
chartOptions: {
type: Object,
required: false
},
},
mounted () {
this.renderChart(this.chartData, this.chartOptions)
}
})
</script>
And this is how it looks like in the app:
<template>
<Navigation />
<div>
<ChanceChart :chartData="state.chartData"/>
</div>
</template>
<script>
import ChanceChart from '../components/ChanceChart.vue';
export default {
components: {
ChanceChart
},
data() {
return {
enemysCards : [1610, 169, 168, 167, 330, 329, 328, 327, 326, 325, 324, 323, 1, 1610, 1600, 169, 168, 167, 1610, 1600, 169, 168, 167, 11],
state: {
chartData: {
datasets: [
{
label: "Enemy's Chance",
borderColor: '#1161ed',
data: [40, 20, 12, 39, 10, 40, 39, 80, 40, 20, 12, 41, 190]
},
{
label: 'My Chance',
borderColor: '#f87979',
color: '#fff',
data: [60,60,60,60,60,60,60,60,60,60,60,60, 60]
}
],
labels: ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13'],
},
chartOptions: {
responsive: true
}
}
}
}
For example i want to take the enemysCards array in the data and the enemysCards.lenght in the labels.

Answer 1

Use computed properties instead of data property :
export default {
components: {
ChanceChart
},
computed: {
chartData(){
return {
datasets: [
{
label: "Enemy's Chance",
borderColor: '#1161ed',
data: this.myFirstArray // <- here
},
{
label: 'My Chance',
borderColor: '#f87979',
color: '#fff',
data: this.mySecondArray // <- here
}
],
labels: this.ennemyCards.map((x, index) => index + 1) // here you can calculate your labels
},
chartOptions: {
responsive: true
}
}
}
data() {
return {
enemysCards : [1610, 169, 168, 167, 330, 329, 328, 327, 326, 325, 324, 323, 1, 1610, 1600, 169, 168, 167, 1610, 1600, 169, 168, 167, 11],
myFirstArray: [40, 20, 12, 39, 10, 40, 39, 80, 40, 20, 12, 41, 190],
mySecondArray: [40, 20, 12, 39, 10, 40, 39, 80, 40, 20, 12, 41, 190],
}
}
