[![npm](https://pivottable.js.org/images/npm.svg)](https://www.npmjs.com/package/pivottable) [![cdnjs](https://pivottable.js.org/images/cdnjs.svg)](https://cdnjs.com/libraries/pivottable) [![tests](https://pivottable.js.org/images/tests.svg)](https://pivottable.js.org/tests/) [![license](https://pivottable.js.org/images/license.svg)](https://github.com/nicolaskruchten/pivottable/blob/master/LICENSE.md)

# PivotTable-Grouping.js

# PivotTable.js
This fork of [PivotTable.js](https://pivottable.js.org/) adds the data grouping capablity, similar to [Subtotal.js](http://nagarajanchinnasamy.com/subtotal/) but made directly in the PivotTable code with the intention of the minimal changes possible. What's more, it introduces `compactLayout` feature to the default `pivotTableRenderer` that arranges the row headers in condensed way.

PivotTable.js is a Javascript Pivot Table library with drag'n'drop functionality built on top of jQuery/jQueryUI and originally written in CoffeeScript by [Nicolas Kruchten](http://nicolas.kruchten.com).
Working demo can be found here: [PivotTable grouping demo](https://jjagielka.github.io/pivottable-grouping-demo/)

It is available under an MIT license from [CDNJS](https://cdnjs.com/libraries/pivottable) and [NPM](https://www.npmjs.com/package/pivottable) and [Bower](http://bower.io/) under the name `pivottable`. And on [Packagist.org](https://packagist.org/packages/nicolaskruchten/pivottable), it is `nicolaskruchten/pivottable`.
| ⚠️ Note! *This is jQuery based version. Check out also other versions: [react-pivottable-grouping](https://github.com/jjagielka/react-pivottable-grouping) and [svelte-pivottable](https://github.com/jjagielka/svelte-pivottable).* |
| --- |

PivotTable.js can be used with [Python/Jupyter](https://github.com/nicolaskruchten/jupyter_pivottablejs) and [R/RStudio](https://github.com/smartinsightsfromdata/rpivotTable) and you can [try it right now](https://pivottable.js.org/examples/local.html) in your browser on a CSV file.
Left image is the default [PivotTable.js](https://pivottable.js.org/) rendering, while right images shows [PivotTable-Grouping.js](https://jjagielka.github.com/pivottable-grouping) with the default _grouping:true_ enabled.

## What does it do?

PivotTable.js' basic function is to enable data exploration and analysis by turning a data set into a summary table and then optionally adding a true 2-d drag'n'drop UI to allow a user to manipulate this summary table, turning it into a pivot table, very similar to the one found in older versions of Microsoft Excel with a bunch of extra developer-oriented features and some visualization effects. With [optional add-ons](https://github.com/nicolaskruchten/pivottable/wiki/Optional-Extra-Renderers), the summary table can be rendered as various kinds of charts, turning the pivot table into a pivot chart.
To enable the `grouping` feature with the default options use:

![image](https://pivottable.js.org/images/animation.gif)

The animation above is based on the [Canadian Parliament 2012 dataset example](https://pivottable.js.org/examples/fully_loaded.html).

## Where are the demos/examples?

There are lots on the [examples page](https://pivottable.js.org/examples/index.html) but here are some good entry points:

* [a JSFiddle where you can play with the code](https://jsfiddle.net/nicolaskruchten/kn381h7s/)
* [a simple demo running on the "Canadian Parliament 2012" dataset](http://nicolaskruchten.github.io/pivottable/examples/mps_prepop.html)
* [fully-loaded demo running on the 700+ datasets that ship with R](https://pivottable.js.org/examples/rcsvs.html)
* [fully-loaded demo where you provide your own CSV file for input](https://pivottable.js.org/examples/local.html)

## Why is it good?

* it's lightweight: the core (without chart support) is a single file with less than 1000 LOC of CoffeeScript, compiles down to 6.3kb of Javascript minified and gzipped, and depends only on jQuery and jQueryUI's 'sortable'
* it works wherever jQuery and jQueryUI work (tested with jQuery 1.8.3 and jQueryUI 1.9.2)
* it works acceptably fast in Chrome on commodity hardware up to around a hundred thousand records, depending on the cardinality of the attributes.
* its UI is [localizable](https://github.com/nicolaskruchten/pivottable/wiki/Localization)
* its layered architecture allows for summary table generation with or without the pivot table UI around it (if you don't use the UI, then there is no dependency on jQueryUI)
* it works with common [input formats](https://github.com/nicolaskruchten/pivottable/wiki/Input-Formats)
* its [derived attributes](https://github.com/nicolaskruchten/pivottable/wiki/Derived-Attributes) can be created on the fly based on the whole input record by passing in a function
* its complex [aggregation functions](https://github.com/nicolaskruchten/pivottable/wiki/Aggregators) can compute values based on the whole input record (e.g. weighted averages)
* it has built-in support for basic heatmap and bar chart [renderers](https://github.com/nicolaskruchten/pivottable/wiki/Renderers), and [optional extra renderers that add charting or TSV export support](https://github.com/nicolaskruchten/pivottable/wiki/Optional-Extra-Renderers)
* its extension points allow aggregation functions, table output, UI and visualizations to be tailored to specific applications
* it works on mobile devices with [jQuery UI Touch Punch](http://touchpunch.furf.com/)
* it has a [test suite](https://pivottable.js.org/tests)

## How do I use the UI?

PivotTable.js implements a pivot table drag'n'drop UI similar to that found in popular spreadsheet programs. You can drag attributes into/out of the row/column areas, and specify rendering, aggregation and filtering options. There is a [step-by-step tutorial](https://github.com/nicolaskruchten/pivottable/wiki/UI-Tutorial) in the wiki.

## How do I load the code?

PivotTable.js implements the [Universal Module Definition (UMD)](https://github.com/umdjs/umd) pattern and so should be compatible with most approaches to script loading and dependency management: direct script loading i.e. from [CDNJS](https://cdnjs.com/libraries/pivottable) or with [RequireJS](http://requirejs.org/), [Browserify](http://browserify.org/) etc. For the latter options, you can grab it from [NPM](https://www.npmjs.com/package/pivottable) with `npm install pivottable` or via [Bower](http://bower.io/) with `bower install pivottable`.

If you are loading the scripts directly (as in the [examples](https://pivottable.js.org)), you need to:

1. load the dependencies:
1. jQuery in all cases
2. jQueryUI for the interactive `pivotUI()` function (see below)
3. D3.js, C3.js and/or Google Charts if you use [charting plugins](https://github.com/nicolaskruchten/pivottable/wiki/Optional-Extra-Renderers)
2. load the PivotTable.js files:
1. `pivot.min.js`
2. any [plugins](https://github.com/nicolaskruchten/pivottable/wiki/Optional-Extra-Renderers) you wish to use

The dependencies and PivotTable.js files can be loaded:

1. By copying the files from their official distributions to your project and loading them locally (the [`dist`](https://github.com/nicolaskruchten/pivottable/tree/master/dist) directory is where you will find the PivotTable.js files)
2. From a Content Distribution Network (CDN) like [CDNJS](https://cdnjs.com/libraries/pivottable)

(The [examples](https://pivottable.js.org) load dependencies from CDNJS and PivotTable.js locally)

## How do I use the code?

There are two main functions provided by PivotTable.js: `pivot()` and `pivotUI()`, both implemented as jQuery plugins, as well as a bunch of helpers and templates.

### `pivot()`
```javascript
$("#output").pivot(data, {
grouping: true,
});
```

Once you've loaded jQuery and pivot.js, this code ([demo](http://nicolaskruchten.github.io/pivottable/examples/simple.html)):
To control the behaviour set `grouping` as an object:

```javascript
$("#output").pivot(
[
{color: "blue", shape: "circle"},
{color: "red", shape: "triangle"}
],
{
rows: ["color"],
cols: ["shape"]
$("#output").pivot(data, {
grouping: {
rowGroupBefore: true, // this is the default value, row grouping above the child rows
colGroupBefore: false, // this is the default value, col grouping after the child cols
}
);
});
```

appends this table to `$("#output")` (the default, *overridable* behaviour is to populate the table cells with counts):

![image](http://nicolaskruchten.github.io/pivottable/images/simple.png)

### `pivotUI()`

A slight change to the code (calling `pivotUI()` instead of `pivot()` ) yields the same table with a drag'n'drop UI around it, so long as you've imported jQueryUI ([demo](http://nicolaskruchten.github.io/pivottable/examples/simple_ui.html)):
By default the `compactLayout` is set when `grouping` is enabled. To switch it off:

```javascript
$("#output").pivotUI(
[
{color: "blue", shape: "circle"},
{color: "red", shape: "triangle"}
],
{
rows: ["color"],
cols: ["shape"]
$("#output").pivot(data, {
grouping: true,
renderingOptions: {
table: {
compactLayout: false,
}
}
);
});
```
Example page is extended with two samples of default usage of grouping capability (marked with the star).

Note that **`pivot()` and `pivotUI()` take different parameters in general**, even though in the example above we passed the same parameters to both. See the [FAQ](https://github.com/nicolaskruchten/pivottable/wiki/Frequently-Asked-Questions#params).

See the wiki for [full parameter documentation](https://github.com/nicolaskruchten/pivottable/wiki/Parameters).

## How can I build the code and run the tests?

To install the development dependencies, just run `npm install`, which will create a `node_modules` directory with the files required to run the [Gulp](http://gulpjs.com/) build system.

After modifying any of the `.coffee` files at the top of the repo, you can compile/minify the files into the `dist` directory by running `node_modules/gulp/bin/gulp.js`

Once that's done, you can point your browser to `tests/index.html` to run the [Jasmine](http://jasmine.github.io/) test suite. You can view the [current test results here](https://pivottable.js.org/tests).

The easiest way to modify the code and work with the examples is to leave a `node_modules/gulp/bin/gulp.js watch serve` command running, which will automatically compile the CoffeeScript files when they are modified and will also run a local web server you can connect to to run the tests and examples.

## How can I contribute?

Pull requests are welcome! Here are some [Contribution Guidelines](https://github.com/nicolaskruchten/pivottable/blob/master/CONTRIBUTING.md).
All other PivotTable.js functionality rest unchanged. (https://github.com/nicolaskruchten/pivottable/)

## I have a question, how can I get in touch?

Please first check the [Frequently Asked Questions](https://github.com/nicolaskruchten/pivottable/wiki/Frequently-Asked-Questions) and if you can't find what you're looking for there, or in the [wiki](https://github.com/nicolaskruchten/pivottable/wiki), then please [create a GitHub Issue](https://github.com/nicolaskruchten/pivottable/issues/new). When creating an issue, please try to provide a replicable test case so that others can more easily help you. Please do not email the author directly, as you will just be asked to create a Github Issue :)
