Turns out i was missing the array position [0]. And I was missing the v-if.
this.chartData.datasets[0].data = data.holders.map((x) => x.share)
Followed the examples here and here
<template>
<Pie
v-if="!loading"
:chart-options="chartOptions"
:chart-data="chartData"
:chart-id="chartId"
:dataset-id-key="datasetIdKey"
:plugins="plugins"
:css-classes="cssClasses"
:styles="styles"
:width="width"
:height="height"
/>
</template>
<script>
import { Pie } from 'vue-chartjs/legacy'
import { Chart as ChartJS, Title, Tooltip, Legend, ArcElement, CategoryScale } from 'chart.js'
