If you’re a fan of visual data representation, donut charts might just be your new best friend. In this blog post, we’ll guide you through creating stunning donut charts using the lightweight Vue component, vue-css-donut-chart. It’s simple to implement and highly customizable, making it perfect for your next project.

Installation

Let’s get started with the installation process. You can use either NPM or the in-browser links. Choose the one that best suits your needs:

Using NPM

• For Yarn: yarn add vue-css-donut-chart
• For NPM: npm i vue-css-donut-chart
• For Pnpm: pnpm add vue-css-donut-chart

Using In-browser

You can include the following code in your HTML file to link to the component:

<link rel="stylesheet" href="https://unpkg.com/vue-css-donut-chart@2/dist/vc-donut.css">
<script src="https://unpkg.com/vue-css-donut-chart@2"></script>

How to Use the Donut Chart Component

Now that we have installed the package, let’s dive into how to use it in your Vue application. Think of your donut chart as a delicious cake. To bake this cake, you’ll need ingredients, which in this case are your chart sections!

Basic Usage

Begin your Vue component like so:

<template>
    <vc-donut :sections="sections"></vc-donut>
</template>

<script setup>
    const sections = [
        { value: 25 }, 
        { value: 25 }
    ];
</script>

Here, you are simply creating a donut with two equal sections. Just like dividing your cake into two halves!

Advanced Usage with Props and Events

If you want more control over your donut chart’s appearance and behavior, you can use multiple props:

<template>
    <vc-donut 
        background="white"
        foreground="grey"
        :size="200"
        unit="px"
        :thickness="30"
        has-legend
        legend-placement="top"
        :sections="sections"
        :total="100"
        :start-angle="0"
        auto-adjust-text-size
        :suppress-validation-warnings="false"
        @section-click="handleSectionClick"
    ></vc-donut>
</template>

<script setup>
    const sections = [
        { label: 'Red section', value: 25, color: 'red' }, 
        { label: 'Green section', value: 25, color: 'green' }, 
        { label: 'Blue section', value: 25, color: 'blue' }
    ];

    const handleSectionClick = (section, event) => {
        console.log(`Section: ${section.label} Event: ${event.type}.`);
    };
</script>

This code is akin to baking a multi-layered cake, with each layer serving a specific flavor and function! Each section is crafted to be unique, just as each shared cake layer contributes to the overall experience.

Understanding the API

The component comes with a variety of props that control its appearance. Here’s a brief rundown:

Props:
- size (Number): Diameter of the donut.
- thickness (Number): Thickness of the donut ring.
- sections (Array): An array of section objects.

These props allow you to dynamically control how your donut looks and functions within your application.

Troubleshooting

If you run into issues while implementing the vue-css-donut-chart, here are some troubleshooting tips:

• Ensure that you have included the CSS file correctly.
• Check Vue compatibility; the component works best with Vue 3.
• If types for TypeScript are not working, update your Vue version.
