## Install

```

## Usage

### Using ChordBox

```javascript

import { ChordBox } from 'vexchords';

const chord = new ChordBox('#selector', {

  // Customizations (all optional, defaults shown)

  width: 100, // canvas width

  height: 120, // canvas height

  circleRadius: 5, // circle radius (width / 20 by default)

  numStrings: 6, // number of strings (e.g., 4 for bass)

  numFrets: 5, // number of frets (e.g., 7 for stretch chords)

  showTuning: true, // show tuning keys

  defaultColor: '#666', // default color

  bgColor: '#FFF', // background color

  strokeColor: '#666', // stroke color (overrides defaultColor)

  textColor: '#666', // text color (overrides defaultColor)

  stringColor: '#666', // string color (overrides defaultColor)

  fretColor: '#666', // fret color (overrides defaultColor)

  labelColor: '#666', // label color (overrides defaultColor)

  fretWidth: 1, // fret width

  stringWidth: 1, // string width

  fontFamily,

  fontSize,

  fontWeight,

  fontStyle, // font settings

  labelWeight // weight of label font

});

chord.draw({

  // array of [string, fret, label (optional)]

  chord: [

    [1, 2],

    [2, 1],

    [3, 2],

    [4, 0], // fret 0 = open string

    [5, 'x'], // fret x = muted string

    [6, 'x']

  ],

  // optional: position marker

  position: 5, // start render at fret 5

  // optional: barres for barre chords

  barres: [

    { fromString: 6, toString: 1, fret: 1 },

    { fromString: 5, toString: 3, fret: 3 }

  ],

  // optional: tuning keys

  tuning: ['E', 'A', 'D', 'G', 'B', 'E']

});

```

### Using the `draw` helper

```javascript

import { draw } from 'vexchords';

// Draw an open D7

draw('#selector', {

  chord: [[1, 2], [2, 1], [3, 2], [4, 0], [5, 'x'], [6, 'x']]

});

```

### Examples

```javascript

import * as vexchords from 'vexchords';

const sel = '#vexchords';

// Draw an open D7

vexchords.draw(sel, {

  chord: [[1, 2], [2, 1], [3, 2], [4, 0], [5, 'x'], [6, 'x']]

});

// Customize size and default color

vexchords.draw(

  sel,

  {

    chord: [[1, 2], [2, 1], [3, 2], [4, 0], [5, 'x'], [6, 'x']]

  },

  { width: 200, height: 240, defaultColor: '#745' }

);

// Set color of circles and bars only

vexchords.draw(

  sel,

  {

    chord: [[2, 3], [3, 3], [4, 3], [6, 'x']],

    position: 5,

    barres: [{ fromString: 5, toString: 1, fret: 1 }]

  },

  { strokeColor: '#8a8' }

);

// Set colors of bridge and text only

vexchords.draw(

  sel,

  {

    chord: [[1, 0], [2, 0], [6, 0]],

    position: 0,

    barres: [{ fromString: 5, toString: 3, fret: 2 }]

  },

  { bridgeColor: '#8a8', textColor: '#8a8' }

);

// Tiny chords, don't show tuning keys

vexchords.draw(

  sel,

  {

    chord: [],

    position: 1,

    barres: [

      { fromString: 6, toString: 1, fret: 1 },

      { fromString: 5, toString: 3, fret: 3 }

    ]

  },

  {

    width: 30,

    height: 40,

    strokeColor: '#745',

    showTuning: false

  }

);
