My problem: I followed the doc from vue-chartjs but the chart is not rendering the data.
Here is my code:
My component Chart.vue
<script>
import { Line } from 'vue3-chart-v2'
export default {
extends: Line,
props: {
chartdata: {
type: Object,
default: null
},
options: {
type: Object,
default: null
}
},
mounted () {
this.renderChart(this.chartdata, this.options)
}
}
</script>
My Home.vue code:
<template>
<div class="container">
<line-chart
v-if="loaded"
:chartdata="chartdata"
:options="options"/>
</div>
</template>
<script>
import LineChart from '../components/Chart.vue'
export default {
name: 'LineChartContainer',
components: { LineChart },
data: () => ({
loaded: false,
chartdata: null,
options: {
responsive: true,
}
}),
async mounted () {
this.loaded = false
try {
const quotes = [
1, 2, 3, 4,
]
this.chartdata = quotes
this.loaded = true
} catch (e) {
console.error(e)
}
}
}
</script>
When I'm rendering the Home view, I see the axis of the chart, but no data inside... In the console, I don't have any errors.
Later, I would like to fetch data from an API. Thus, the quotes would receive data from an external API. Here I just put some fake data for testing.
Does anyone can help me ? Thks
I was missing the import { defineComponent } from 'vue' in my component. Now it works using the below code.
<template>
<div class="container">
<line-chart
v-if="loaded"
:chartdata="chartdata"
:options="options"/>
</div>
</template>
<script>
import LineChart from '../components/Chart.vue'
import { defineComponent } from 'vue'
export default defineComponent({
name: 'LineChartContainer',
components: { LineChart },
data: () => ({
loaded: false,
chartdata: null,
options: {
responsive: true,
}
}),
async mounted () {
this.loaded = false
try {
const quotes = [
1, 2, 3, 4,
]
this.chartdata = quotes
this.loaded = true
} catch (e) {
console.error(e)
}
}
})
</script>
