# react-d3-components > D3 Components for React Let React have complete control over the DOM even when using D3. This way we can benefit from Reacts Virtual DOM. ![charts](http://codesuki.github.io/react-d3-components/charts.png) ## Table of Contents * [Installation](#installation) * [Development](#development) * [Description](#description) * [Documentation](#documentation) * [Features](#features) * [Todo](#todo) * [Changelog](#changelog) * [Examples](#examples) * [Bar Chart](#barchart) * [Brush](#brush) * [Tooltips](#tooltips) * [Axis parameters](#axis-parameters) * [Custom accessors](#custom-accessors) * [Customization](#overriding-default-parameters) * [Stacked Bar Chart](#stackedbarchart) * [Grouped Bar Chart](#groupedbarchart) * [Scatter, Line and Area Charts](#other-charts) * [Pie Chart](#piechart) * [Waveform](#waveform) ## Installation ``` npm install react-d3-components ``` ## Development In order to compile the code, from the repository folder, type in your terminal ``` npm install & npm run build:js ``` This will install the dependencies required and run the build:js. At the end of the process the compiled .js and min.js will be available in the dist folder. Examples are available in the folder example. From the root folder type ``` python -m SimpleHTTPServer 8000 ``` to start a webserver, and navigate to http://localhost:8000/example in order to visualize the new example page. Note that the example page directly points to the dist folder. ## Description Ideally the library should be usable with minimum configuration. Just put the data in and see the charts. I try to provide sensible defaults, but since for most use-cases we need to customize D3's parameters they will be made accessible to the user. Most Charts will turn into their stacked variant when given an array as input. If you like the project please consider starring and a pull request. I am open for any additions. ## Documentation Documentation is in the [Wiki](https://github.com/codesuki/react-d3-components/wiki). For quick testing the [examples](#examples) might be enough. ## Features * Brushes * Tooltips * Custom accessors to support any data format * Negative axes * CSS classes to allow styling * Bar Chart * Stacked Bar Chart * Scatter Plot * Line Chart * Area Chart * Stacked Area Chart * Pie Plot ## Todo * More Charts * Animations * Legend * Documentation * Tests ## Changelog * 0.6.6: Fix ticks rendering over bar chart * 0.6.5: * Add tickDirection property to Axis * Add hideLabels property to PieChart * Add yOrientation property to AreaChart * Fix Line Chart rendering * 0.6.4: Fixed react dependency version (was 0.15.0 instead of 15.0.0) * 0.6.3: Changed react dependency version to >=0.14.0 to allow react 0.15. * 0.6.2: Fixed build system.

My personal use-case is to select date ranges as shown below and in the example. The Brush feature is still incomplete, for now only offering a x-Axis Brush but y-Axis will follow soon as well as refactoring. For now the Brush is rendered in its own SVG, this allows flexible use but might change in the future, or become optional. Also there is no Brush support for the built-in default Scales. ```css .brush .extent { stroke: #000; fill-opacity: .125; shape-rendering: crispEdges; } .brush .background { fill: #ddd; } ``` ```javascript var LineChart = ReactD3.LineChart; var Brush = ReactD3.Brush; var SomeComponent = React.createClass({ getInitialState: function() { return { data: {label: '', values: [ {x: new Date(2015, 2, 5), y: 1}, {x: new Date(2015, 2, 6), y: 2}, {x: new Date(2015, 2, 7), y: 0}, {x: new Date(2015, 2, 8), y: 3}, {x: new Date(2015, 2, 9), y: 2}, {x: new Date(2015, 2, 10), y: 3}, {x: new Date(2015, 2, 11), y: 4}, {x: new Date(2015, 2, 12), y: 4}, {x: new Date(2015, 2, 13), y: 1}, {x: new Date(2015, 2, 14), y: 5}, {x: new Date(2015, 2, 15), y: 0}, {x: new Date(2015, 2, 16), y: 1}, {x: new Date(2015, 2, 16), y: 1}, {x: new Date(2015, 2, 18), y: 4}, {x: new Date(2015, 2, 19), y: 4}, {x: new Date(2015, 2, 20), y: 5}, {x: new Date(2015, 2, 21), y: 5}, {x: new Date(2015, 2, 22), y: 5}, {x: new Date(2015, 2, 23), y: 1}, {x: new Date(2015, 2, 24), y: 0}, {x: new Date(2015, 2, 25), y: 1}, {x: new Date(2015, 2, 26), y: 1} ]}, xScale: d3.time.scale().domain([new Date(2015, 2, 5), new Date(2015, 2, 26)]).range([0, 400 - 70]), xScaleBrush: d3.time.scale().domain([new Date(2015, 2, 5), new Date(2015, 2, 26)]).range([0, 400 - 70]) }; }, render: function() { return (

); }, _onChange: function(extent) { this.setState({xScale: d3.time.scale().domain([extent[0], extent[1]]).range([0, 400 - 70])}); } }); ``` ![brush](http://codesuki.github.io/react-d3-components/brush.png) ### Tooltips You can provide a callback to every chart that will return html for the tooltip. Depending on the type of chart the callback will receive different parameters that are useful. * Bar Chart: label is the first parameter. y0, y of the hovered bar and the total bar height in case of a stacked bar chart. * Scatter Plot: x, y of the hovered point. * Pie Chart: label is the first parameter. y of the hovered wedge. * Area Chart: closest y value to the cursor of the area under the mouse and the cumulative y value in case of a stacked area chart. x value is the third parameter. label is the fourth parameter. Example Scatter Plot: ```javascript var tooltipScatter = function(x, y) { return "x: " + x + " y: " + y; }; React.render(, document.getElementById('scatterplot') ); ``` Tooltip positioning is influenced by `tooltipOffset` `tooltipContained` and `tooltipMode`, which has 3 options `mouse`, `fixed`, `element`. * `mouse` is the default behavior and just follows the mouse * `fixed` uses `tooltipOffset` as an offset from the top left corner of the svg * `element` puts the tooltip on top of data points for line/area/scatter charts and on top of bars for the barchart `tooltipOffset` is an object with `top` and `left` keys i.e. `{top: 10, left: 10}` If `tooltipContained` is true the tooltip will try to stay inside the svg by using `css-transform`. ![tooltip](http://codesuki.github.io/react-d3-components/tooltip.png) ### Axis parameters All D3 axis parameters can optionally be provided to the chart. For detailed explanation please check the documentation. ```javascript React.render(, document.getElementById('linechart')); ``` The following are the default values. ```javascript { tickArguments: [10], tickValues: null, tickFormat: x => { return x; }, innerTickSize: 6, tickPadding: 3, outerTickSize: 6, className: "axis", zero: 0, label: "" } ``` ### Custom Accessors ```javascript data = [{ customLabel: 'somethingA', customValues: [[0, 3], [1.3, -4], [3, 7], [-3.5, 8], [4, 7], [4.5, 7], [5, -7.8]] }]; var labelAccessor = function(stack) { return stack.customLabel; }; var valuesAccessor = function(stack) { return stack.customValues; }; var xAccessor = function(element) { return element[0]; }; var yAccessor = function(element) { return element[1]; }; React.render(, document.getElementById('location')); ``` ### Overriding default parameters All Charts provide defaults for scales, colors, etc... If you want to use your own scale just pass it to the charts constructor. The scales are normal D3 objects, their documentation can be found [here](https://github.com/d3/d3-3.x-api-reference/blob/master/Ordinal-Scales.md) and [here](https://github.com/d3/d3-3.x-api-reference/blob/master/Quantitative-Scales.md). There are more parameters like barPadding, strokeWidth, fill, opacity, etc. please check the documentation for details. ```javascript var xScale = d3.scale.ordinal(); //... + set it up appropriately var yScale = d3.scale.linear(); var colorScale = d3.scale.category20(); ``` #### LineChart stroke style You can customize the line style of LineCharts with CSS or if you want to have more control over how each line in your dataset gets rendered you can use the stroke property of LineChart as follows. Note that you do not have to set all the properties in the object. ```javascript var dashFunc = function(label) { if (label == "somethingA") { return "4 4 4"; } if (label == "somethingB") { return "3 4 3"; } } var widthFunc = function(label) { if (label == "somethingA") { return "4"; } if (label == "somethingB") { return "2"; } } var linecapFunc = function(label) { if (label == "somethingA") { return "round"; } } React.render(, document.getElementById('linechart') ); ``` ![strokestyle](http://codesuki.github.io/react-d3-components/strokestyle.png) ### StackedBarChart ```javascript var BarChart = ReactD3.BarChart; data = [ { label: 'somethingA', values: [{x: 'SomethingA', y: 10}, {x: 'SomethingB', y: 4}, {x: 'SomethingC', y: 3}] }, { label: 'somethingB', values: [{x: 'SomethingA', y: 6}, {x: 'SomethingB', y: 8}, {x: 'SomethingC', y: 5}] }, { label: 'somethingC', values: [{x: 'SomethingA', y: 6}, {x: 'SomethingB', y: 8}, {x: 'SomethingC', y: 5}] } ]; React.render(, document.getElementById('location')); ``` ![stackedbarchart](http://codesuki.github.io/react-d3-components/stackedbarchart.png) ### Grouped Bar Chart ```javascript var BarChart = ReactD3.BarChart; data = [ { label: 'somethingA', values: [{x: 'SomethingA', y: 10}, {x: 'SomethingB', y: 4}, {x: 'SomethingC', y: 3}] }, { label: 'somethingB', values: [{x: 'SomethingA', y: 6}, {x: 'SomethingB', y: 8}, {x: 'SomethingC', y: 5}] }, { label: 'somethingC', values: [{x: 'SomethingA', y: 6}, {x: 'SomethingB', y: 8}, {x: 'SomethingC', y: 5}] } ]; React.render(, document.getElementById('location')); ``` ![groupedbarchart](http://codesuki.github.io/react-d3-components/groupedbarchart.png) ### Other Charts ```javascript var ScatterPlot = ReactD3.ScatterPlot; var LineChart = ReactD3.LineChart; var AreaChart = ReactD3.AreaChart; data = [ { label: 'somethingA', values: [{x: 0, y: 2}, {x: 1.3, y: 5}, {x: 3, y: 6}, {x: 3.5, y: 6.5}, {x: 4, y: 6}, {x: 4.5, y: 6}, {x: 5, y: 7}, {x: 5.5, y: 8}] }, { label: 'somethingB', values: [{x: 0, y: 3}, {x: 1.3, y: 4}, {x: 3, y: 7}, {x: 3.5, y: 8}, {x: 4, y: 7}, {x: 4.5, y: 7}, {x: 5, y: 7.8}, {x: 5.5, y: 9}] } ]; React.render(, document.getElementById('location')); React.render(, document.getElementById('location') ); React.render(, document.getElementById('location') ); ``` ![scatterplot](http://codesuki.github.io/react-d3-components/scatterplot.png) ![linechart](http://codesuki.github.io/react-d3-components/linechart.png) ![areachart](http://codesuki.github.io/react-d3-components/areachart.png) ### PieChart By default d3 sorts the PieChart but you can use the sort property to pass a custom comparator or null to disable sorting. ```javascript var PieChart = ReactD3.PieChart; var data = { label: 'somethingA', values: [{x: 'SomethingA', y: 10}, {x: 'SomethingB', y: 4}, {x: 'SomethingC', y: 3}] }; var sort = null; // d3.ascending, d3.descending, func(a,b) { return a - b; }, etc... React.render(, document.getElementById('location') ); ``` ![piechart](http://codesuki.github.io/react-d3-components/piechart.png) ### Waveform The waveform chart displays a sequence of values as if they were part of an audio waveform. The values are centered on the horizontal axis and reflected along the horizontal origin. For now only values in the range [0,1] are supported. The graph can accept a colorScale parameter, that is an array of values in the range [0,width], where width is the width of the graph. Following an example of gradient from white to black for a waveform of width 200. ```javascript colorScale={ d3.scale.linear() .domain([0,200]) .range(['#fff','#000'])} ``` The graph is responsive and adopts a viewBox strategy to resize the graph maintaining its proportions. We also adopt subSampling in order to maintain the graph rapresentation of the waveform. As it is now each bar needs to have a minimum width of 1px, as well as 1px space between to adjacent bars. In order to allow this, we subsample the input data in order to have exactly a maximum of width/2 elements. It is therefore a good strategy to select the width of the graph to be twice the length of the dataset. The viewBox responsiveness will then resize the graph to the width of the container. If the samples are less than half of the space available we just display them with a width >1px. Space between bars is increased in width as well. ![waveform](http://codesuki.github.io/react-d3-components/waveform.png) ## Credits This library uses parts of [D3.js](https://github.com/mbostock/d3).
