# chart-merger

Merge data from different streams of data with `x` and `y` keys.

## Multiply some streams

```javascript

var multiplyStreams = require('chart-merger').multiply;

var streamA = [

  { x: 1, y: 3 },

  { x: 2, y: 4 },

  { x: 3, y: 2 }

];

var streamB = [

  { x: 1, y: 2 },

  { x: 2, y: 3 },

  { x: 3, y: 4 },

];

var multipliedStreams = multiplyStreams(streamA, streamB);

console.log(multipliedStreams);

// [

//   { x: 1, y: 6 },

//   { x: 2, y: 12 },

//   { x: 3, y: 8 }

// ]

```

## Divide some streams

```javascript

var dividedStreams = require('chart-merger').divide;

var streamA = [

  { x: 1, y: 3 },

  { x: 2, y: 4 },

  { x: 3, y: 2 }

];

var streamB = [

  { x: 1, y: 2 },

  { x: 2, y: 3 },

  { x: 3, y: 4 },

];

var dividedStreams = divideStreams(streamA, streamB);

console.log(dividedStreams);

// [

//   { x: 1, y: 1.5 },

//   { x: 2, y: 1.33 },

//   { x: 3, y: 0.5 }

// ]

```

## Sum some streams

```javascript

var sumStreams = require('chart-merger').sum;

var streamA = [

  { x: 1, y: 3 },

  { x: 2, y: 4 },

  { x: 3, y: 2 }

];

var streamB = [

  { x: 1, y: 2 },

  { x: 2, y: 3 },

  { x: 3, y: 4 },

];

var summedStreams = sumStreams(streamA, streamB);

console.log(summedStreams);

// [

//   { x: 1, y: 5 },

//   { x: 2, y: 7 },

//   { x: 3, y: 6 }

// ]

```

## Average some streams

```javascript

var averageStreams = require('chart-merger').average;

var streamA = [

  { x: 1, y: 3 },

  { x: 2, y: 4 },

  { x: 3, y: 2 }

];

var streamB = [

  { x: 1, y: 2 },

  { x: 2, y: 3 },

  { x: 3, y: 4 },

];

var averagedStreams = averageStreams(streamA, streamB);

console.log(averagedStreams);

// [

//   { x: 1, y: 2.5 },

//   { x: 2, y: 3.5 },

//   { x: 3, y: 3 }

// ]
