*[Chart.js](https://www.chartjs.org) plugin to create charts with a hand-drawn, sketchy, appearance*
Version 0.2 requires Chart.js 2.7.0 or later, and [Rough.js](https://roughjs.com) 2.0.1 or later.
## Installation
You can download the latest version of chartjs-plugin-rough from the [GitHub releases](https://github.com/nagix/chartjs-plugin-rough/releases/latest).
To install via npm:
```bash
npm install chartjs-plugin-rough --save
```
To install via bower:
```bash
bower install chartjs-plugin-rough --save
```
To use CDN:
```html
```
```html
```
## Usage
chartjs-plugin-rough can be used with ES6 modules, plain JavaScript and module loaders.
chartjs-plugin-rough requires [Chart.js](https://www.chartjs.org) and [Rough.js](https://roughjs.com). Include Chart.js, Rough.js and chartjs-plugin-rough.js to your page to render sketchy charts. Note that chartjs-plugin-rough must be loaded after the Chart.js and Rough.js libraries. Once imported, the plugin is available under the global property `ChartRough`.
Then, you need to register the plugin to enable it for all charts in the page.
```js
Chart.plugins.register(ChartRough);
```
Or, you can enable the plugin only for specific charts.
```js
var chart = new Chart(ctx, {
plugins: [ChartRough],
options: {
// ...
}
});
```
### Usage in ES6 as module
Import the module as `ChartRough`, and register it in the same way as described above.
```js
import ChartRough from 'chartjs-plugin-rough';
```
## Tutorial and Samples
You can find a tutorial and samples at [nagix.github.io/chartjs-plugin-rough](https://nagix.github.io/chartjs-plugin-rough).
## Configuration
The plugin options can be changed at 3 different levels and are evaluated with the following priority:
- per dataset: `dataset.rough.*`
- per chart: `options.plugins.rough.*`
- globally: `Chart.defaults.global.plugins.rough.*`
All available options are listed below. [This example](https://nagix.github.io/chartjs-plugin-rough/samples/interactions.html) shows how each option affects the appearance of a chart.
| Name | Type | Default | Description
| ---- | ---- | ------- | -----------
| `roughness` | `number` | `1` | Numerical value indicating how rough the drawing is. See [Rough.js](https://github.com/pshihn/rough/wiki#roughness).
| `bowing` | `number` | `1` | Numerical value indicating how curvy the lines are when drawing a sketch. See [Rough.js](https://github.com/pshihn/rough/wiki#bowing).
| `fillStyle` | `string` | `'hachure'` | String value representing the fill style. See [Rough.js](https://github.com/pshihn/rough/wiki#fillstyle).
| `fillWeight` | `number` | `0.5` | Numeric value representing the width of the hachure lines. See [Rough.js](https://github.com/pshihn/rough/wiki#fillweight).
| `hachureAngle` | `number` | `-41` | Numerical value (in degrees) that defines the angle of the hachure lines. See [Rough.js](https://github.com/pshihn/rough/wiki#hachureangle).
| `hachureGap` | `number` | `4` | Numerical value that defines the average gap, in pixels, between two hachure lines. See [Rough.js](https://github.com/pshihn/rough/wiki#hachuregap).
| `curveStepCount` | `number` | `9` | When drawing circles and arcs, the plugin approximates `curveStepCount` number of points to estimate the shape. See [Rough.js](https://github.com/pshihn/rough/wiki#curvestepcount).
| `simplification` | `number` | `0` | When drawing lines, simplification can be set to simplify the shape by the specified factor. The value can be between 0 and 1. See [Rough.js](https://github.com/pshihn/rough/wiki#simplification).
For example:
```js
{
type: 'bar',
data: {
labels: ['January', 'February', 'March', 'April', 'May', 'June'],
datasets: [{
data: [45, 20, 64, 32, 76, 51],
backgroundColor: 'rgb(255, 99, 132)',
borderColor: 'rgb(255, 99, 132)',
borderWidth: 3,
rough: {
roughness: 1,
bowing: 1,
fillStyle: 'hachure',
fillWeight: 0.5,
hachureAngle: -41,
hachureGap: 4,
curveStepCount: 9,
simplification: 0
}
}]
}
}
```
Note that the following line style options are ignored.
- `borderCapStyle`
- `borderDash`
- `borderDashOffset`
- `borderJoinStyle`
- `borderAlign`
