MTW-BOILERPLATE-CHARTS

Full Report: Last One

This boilerplate allows you to develop quickly and easily chart canvas bundles. It has two modes. The result of production mode is a minimized bundle. You can embed this bundle on a website and then automatically update the chart's datasets continuously, for example.

In development mode, the chart files are watched. This means, if you edit them and save your changes, the charts will be recompiled and reloaded immediately. Feel free to adapt the existing charts or create a completely new one. If you need inspiration, check out Chart.js Samples or Awesome Chart.js. There you can see what's possible.

| Setup

To enable local operation of this boilerplate, you can do the following:

1. open your terminal and define your startup file MYSTARTUPFILE in use
   • e. g. for Zsh

      MYSTARTUPFILE=".zshrc"

   • or for pure Bash

      MYSTARTUPFILE=".bashrc" # or .bash_profile for macOS

2. install nvm and source your startup file again

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash
   source ~/$MYSTARTUPFILE

3. if your terminal has closed, open it again and continue
4. execute to install Node.js
5. clone the repository git clone https://github.com/mythemeway/mtw-boilerplate-charts or your fork to your local machine
6. change your current directory to mtw-boilerplate-charts cd mtw-boilerplate-charts
7. run npm install

Note: If you've already installed you only have to do steps 5-7.

That's it.

| Boilerplate Usage

Run Development Mode

Go to the mtw-boilerplate-charts directory on your local machine and execute npm start. The result will appear at e. g. http://localhost:8080.

Run Production Mode

There are two ways to get your minimized bundle.

Way 1: npm run build = without terser [default] [faster]

Way 2: npm run terser = with terser additionally [smaller]

Note: output directory is always ~/mtw-boilerplate-charts/dist

Embed Chart

<div style="position:relative; height:40vh; width:80vw">
	<canvas id="mtw-canvas"></canvas>
</div>
<script src="./canvas.bundle.min.js"></script>

Note: responsive charts require special embedding treatment

Switch Chart

1. open ~/mtw-boilerplate-charts/canvas.config.js
2. change const canvas and save it

   // 
   // CANVAS SETTINGS
   //  - path:  path to canvas
   //  - id:    canvas id attribute
   //  
   
   // const canvas = { path: './src/chartjs/mtw-chart-line.js', id: 'mtw-canvas' };
   // const canvas = { path: './src/chartjs/mtw-chart-bar.js', id: 'mtw-canvas' };
   const canvas = { path: './src/chartjs/mtw-chart-polar.js', id: 'mtw-canvas' };
   // const canvas = { path: './src/chartjs/mtw-chart-bubble.js', id: 'mtw-canvas' };
   
   module.exports = canvas;

Add Chart

1. put mtw-chart-new.js into the ~/mtw-boilerplate-charts/src/... directory
2. follow the switch chart procedure

   // 
   // CANVAS SETTINGS
   //  - path:  path to canvas
   //  - id:    canvas id attribute
   //  
   
   // const canvas = { path: './src/chartjs/mtw-chart-line.js', id: 'mtw-canvas' };
   // const canvas = { path: './src/chartjs/mtw-chart-bar.js', id: 'mtw-canvas' };
   // const canvas = { path: './src/chartjs/mtw-chart-polar.js', id: 'mtw-canvas' };
   // const canvas = { path: './src/chartjs/mtw-chart-bubble.js', id: 'mtw-canvas' };
   const canvas = { path: './src/chartjs/mtw-chart-new.js', id: 'new-canvas' };
   
   module.exports = canvas;

Note:

• your canvas id attribute setting is only used in production mode; in development mode it is always the default mtw-canvas

• if you switch/add a chart in development mode, the result is displayed immediately after saving your changes
