To use chart.js in Nuxt.js, you will first need to install the necessary dependencies. You can do this by running the command npm install chart.js vue-chartjs in your project directory.
Next, you will need to import these packages in your Nuxt.js component where you want to use the chart. Import Chart.js and VueChartJs at the top of your component file using the following code:
1 2 |
import Chart from 'chart.js'; import { Bar, Line } from 'vue-chartjs' |
Now, you can create a new Vue component that extends the appropriate chart type (Bar, Line, etc) and configure the chart inside the mounted hook. For example, to create a Bar chart, you can create a new component like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
export default { extends: Bar, mounted () { this.renderChart({ labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'], datasets: [ { label: 'Data One', backgroundColor: '#f87979', data: [40, 20, 12, 39, 10, 40, 39] } ] }, {responsive: true, maintainAspectRatio: false}) } } |
Finally, include this chart component in your Nuxt.js page by adding the following code to your template:
1 2 3 4 5 |
<template> <div> <bar-chart></bar-chart> </div> </template> |
Now, when you run your Nuxt.js application, you should see the chart displaying on the page. You can customize the chart further by exploring the chart.js documentation and the Vue ChartJS documentation.
