Marking and annotation skills for Vue statistical charts
In Vue development, using statistical charts to display data is a very common requirement. For a good statistical chart, in addition to visually displaying data, marks and annotations are also very important parts. This article will introduce some marking and annotation techniques in Vue statistical charts and demonstrate them through code examples.
Marking Tips
<template> <div> <bar-chart :data="data" :options="options"></bar-chart> </div> </template> <script> import { Bar } from 'vue-chartjs' export default { components: { BarChart: Bar }, data() { return { data: { labels: ['January', 'February', 'March', 'April', 'May'], datasets: [{ label: 'Sales', backgroundColor: '#f87979', data: [12, 19, 3, 5, 2] }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero: true } }] } } } } } </script>
<template> <div> <line-chart :data="data" :options="options"></line-chart> </div> </template> <script> import { Line } from 'vue-chartjs' export default { components: { LineChart: Line }, data() { return { data: { labels: ['January', 'February', 'March', 'April', 'May'], datasets: [{ label: 'Sales', borderColor: '#f87979', data: [12, 19, 3, 5, 2], fill: false }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero: true } }] } } } } } </script>
