# react-pivottable
`react-pivottable` is a React-based pivot table library with drag'n'drop
functionality. It is a React port of the jQuery-based
[PivotTable.js](https://pivottable.js.org/) by the same author.
`react-pivottable` is part of Plotly's [React Component Suite](https://plot.ly/products/react/) for building data visualization Web apps and products.
## What does it do & where is the demo?
`react-pivottable`'s function is to enable data exploration and analysis by
summarizing a data set into table or [Plotly.js](https://plot.ly/javascript/)
chart with a true 2-d drag'n'drop UI, very similar to the one found in older
versions of Microsoft Excel.
A [live demo can be found here](https://react-pivottable.js.org/).
## How can I use it in my project?
### Drag'n'drop UI with Table output only
Installation is via NPM and has a peer dependency on React:
```
npm install --save react-pivottable react react-dom
```
Basic usage is as follows. Note that `PivotTableUI` is a "dumb component" that
maintains essentially no state of its own.
```js
import React from 'react';
import ReactDOM from 'react-dom';
import PivotTableUI from 'react-pivottable/PivotTableUI';
import 'react-pivottable/pivottable.css';
// see documentation for supported input formats
const data = [['attribute', 'attribute2'], ['value1', 'value2']];
class App extends React.Component {
constructor(props) {
super(props);
this.state = props;
}
render() {
return (
this.setState(s)}
{...this.state}
/>
);
}
}
ReactDOM.render(, document.body);
```
### Drag'n'drop UI with Plotly charts as well as Table output
The Plotly `react-plotly.js` component can be passed in via dependency
injection. It has a peer dependency on `plotly.js`.
**Important:** If you build your project using webpack, you'll have to follow
[these instructions](https://github.com/plotly/plotly.js#building-plotlyjs-with-webpack)
in order to successfully bundle `plotly.js`. See below for how to avoid having
to bundle `plotly.js`.
```
npm install --save react-pivottable react-plotly.js plotly.js react react-dom
```
To add the Plotly renderers to your app, you can use the following pattern:
```js
import React from 'react';
import PivotTableUI from 'react-pivottable/PivotTableUI';
import 'react-pivottable/pivottable.css';
import TableRenderers from 'react-pivottable/TableRenderers';
import Plot from 'react-plotly.js';
import createPlotlyRenderers from 'react-pivottable/PlotlyRenderers';
// create Plotly renderers via dependency injection
const PlotlyRenderers = createPlotlyRenderers(Plot);
// see documentation for supported input formats
const data = [['attribute', 'attribute2'], ['value1', 'value2']];
class App extends React.Component {
constructor(props) {
super(props);
this.state = props;
}
render() {
return (
this.setState(s)}
renderers={Object.assign({}, TableRenderers, PlotlyRenderers)}
{...this.state}
/>
);
}
}
ReactDOM.render(, document.body);
```
#### With external `plotly.js`
If you would rather not install and bundle `plotly.js` but rather get it into
your app via something like `` tag, you can ignore `react-plotly.js`'
peer-dependcy warning and handle the dependency injection like this:
```js
import React from 'react';
import PivotTableUI from 'react-pivottable/PivotTableUI';
import 'react-pivottable/pivottable.css';
import TableRenderers from 'react-pivottable/TableRenderers';
import createPlotlyComponent from 'react-plotly.js/factory';
import createPlotlyRenderers from 'react-pivottable/PlotlyRenderers';
// create Plotly React component via dependency injection
const Plot = createPlotlyComponent(window.Plotly);
// create Plotly renderers via dependency injection
const PlotlyRenderers = createPlotlyRenderers(Plot);
// see documentation for supported input formats
const data = [['attribute', 'attribute2'], ['value1', 'value2']];
class App extends React.Component {
constructor(props) {
super(props);
this.state = props;
}
render() {
return (
<PivotTableUI
data={data}
onChange={s => this.setState(s)}
renderers={Object.assign({}, TableRenderers, PlotlyRenderers)}
{...this.state}
/>
);
}
}
ReactDOM.render(<App />, document.body);
```
## Properties and layered architecture
* `<PivotTableUI {...props} />`
* `<PivotTable {...props} />`
* `<Renderer {...props} />`
* `PivotData(props)`
The interactive component provided by `react-pivottable` is `PivotTableUI`, but
output rendering is delegated to the non-interactive `PivotTable` component,
which accepts a subset of its properties. `PivotTable` can be invoked directly
and is useful for outputting non-interactive saved snapshots of `PivotTableUI`
configurations. `PivotTable` in turn delegates to a specific renderer component,
such as the default `TableRenderer`, which accepts a subset of the same
properties. Finally, most renderers will create non-React `PivotData` object to
handle the actual computations, which also accepts a subset of the same props as
the rest of the stack.
Here is a table of the properties accepted by this stack, including an
indication of which layer consumes each, from the bottom up:
| Layer | Key & Type | Default Value | Description |
| -------------- | ------------------------------------------------ | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `PivotData` | `data` <br /> see below for formats | (none, required) | data to be summarized |
| `PivotData` | `rows` <br /> array of strings | `[]` | attribute names to prepopulate in row area |
| `PivotData` | `cols` <br /> array of strings | `[]` | attribute names to prepopulate in cols area |
| `PivotData` | `vals` <br /> array of strings | `[]` | attribute names used as arguments to aggregator (gets passed to aggregator generating function) |
| `PivotData` | `aggregators` <br /> object of functions | `aggregators` from `Utilites` | dictionary of generators for aggregation functions in dropdown (see [original PivotTable.js documentation](https://github.com/nicolaskruchten/pivottable/wiki/Aggregators)) |
| `PivotData` | `aggregatorName` <br /> string | first key in `aggregators` | key to `aggregators` object specifying the aggregator to use for computations |
| `PivotData` | `valueFilter` <br /> object of arrays of strings | `{}` | object whose keys are attribute names and values are objects of attribute value-boolean pairs which denote records to include or exclude from computation and rendering; used to prepopulate the filter menus that appear on double-click |
| `PivotData` | `sorters` <br /> object or function | `{}` | accessed or called with an attribute name and can return a [function which can be used as an argument to `array.sort`](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/sort) for output purposes. If no function is returned, the default sorting mechanism is a built-in "natural sort" implementation. Useful for sorting attributes like month names, see [original PivotTable.js example 1](http://nicolas.kruchten.com/pivottable/examples/mps_agg.html) and [original PivotTable.js example 2](http://nicolas.kruchten.com/pivottable/examples/montreal_2014.html). |
| `PivotData` | `rowOrder` <br /> string | `"key_a_to_z"` | the order in which row data is provided to the renderer, must be one of `"key_a_to_z"`, `"value_a_to_z"`, `"value_z_to_a"`, ordering by value orders by row total |
| `PivotData` | `colOrder` <br /> string | `"key_a_to_z"` | the order in which column data is provided to the renderer, must be one of `"key_a_to_z"`, `"value_a_to_z"`, `"value_z_to_a"`, ordering by value orders by column total |
| `PivotData` | `derivedAttributes` <br /> object of functions | `{}` | defines derived attributes (see [original PivotTable.js documentation](https://github.com/nicolaskruchten/pivottable/wiki/Derived-Attributes)) |
| `Renderer` | `<any>` | (none, optional) | Renderers may accept any additional properties |
| `PivotTable` | `renderers` <br /> object of functions | `TableRenderers` | dictionary of renderer components |
| `PivotTable` | `rendererName` <br /> string | first key in `renderers` | key to `renderers` object specifying the renderer to use |
| `PivotTableUI` | `onChange` <br /> function | (none, required) | function called every time anything changes in the UI, with the new value of the properties needed to render the new state. This function must be hooked into a state-management system in order for the "dumb" `PivotTableUI` component to work. |
| `PivotTableUI` | `hiddenAttributes` <br /> array of strings | `[]` | contains attribute names to omit from the UI |
| `PivotTableUI` | `hiddenFromAggregators` <br /> array of strings | `[]` | contains attribute names to omit from the aggregator arguments dropdowns |
| `PivotTableUI` | `hiddenFromDragDrop` <br /> array of strings | `[]` | contains attribute names to omit from the drag'n'drop portion of the UI |
| `PivotTableUI` | `menuLimit` <br /> integer | 500 | maximum number of values to list in the double-click menu |
| `PivotTableUI` | `unusedOrientationCutoff` <br /> integer | 85 | If the attributes' names' combined length in characters exceeds this value then the unused attributes area will be shown vertically to the left of the UI instead of horizontally above it. `0` therefore means 'always vertical', and `Infinity` means 'always horizontal'. |
### Accepted formats for `data`
#### Arrays of objects
One object per record, the object's keys are the attribute names.
_Note_: missing attributes or attributes with a value of `null` are treated as
if the value was the string `"null"`.
```js
const data = [
{
attr1: 'value1_attr1',
attr2: 'value1_attr2',
//...
},
{
attr1: 'value2_attr1',
attr2: 'value2_attr2',
//...
},
//...
];
```
#### Arrays of arrays
One sub-array per record, the first sub-array contains the attribute names. If
subsequent sub-arrays are shorter than the first one, the trailing values are
treated as if they contained the string value `"null"`. If subsequent sub-arrays
are longer than the first one, excess values are ignored. This format is
compatible with the output of CSV parsing libraries like PapaParse.
```js
const data = [
['attr1', 'attr2'],
['value1_attr1', 'value1_attr2'],
['value2_attr1', 'value2_attr2'],
//...
];
```
#### Functions that call back
The function will be called with a callback that takes an object as a parameter.
_Note_: missing attributes or attributes with a value of `null` are treated as
if the value was the string `"null"`.
```js
const data = function(callback) {
callback({
"attr1": "value1_attr1",
"attr2": "value1_attr2",
//...
});
callback({
"attr1": "value2_attr1",
"attr2": "value2_attr2",
//...
};
//...
};
```
