XYPlot

XYPlot allows you to make line charts, area charts, scatterplots, heat maps, etc with animations and different interactions between them.

Currently following components are used for this purpose:

  • XYPlot to wrap all the items.
  • Grids to show vertical and horizontal grids.
  • Axes to show X and Y axis.
  • Different kinds of series for line/area/bar charts, scatterplots, heat maps, etc.
  • Hint to show the selected hint.
  • Crosshair for crosshairs.

Usage

Import the necessary components from the library…

import {XYPlot, XAxis, YAxis, HorizontalGridLines, LineSeries} from 'react-vis';

… and add the following code to your render function:

<XYPlot
  width={300}
  height={300}>
  <HorizontalGridLines />
  <LineSeries
    color="red"
    data={[
      {x: 1, y: 10},
      {x: 2, y: 5},
      {x: 3, y: 15}
    ]}/>
  <XAxis title="X" />
  <YAxis />
</XYPlot>

Common concepts

XYPlot is a wrapper for series, hints, axes and other components. Most of these components do not require any properties by default, however it is expected that the user will pass the data property into each series.

data is an array of objects. Each item is some point on the chart. Object may contain following properties:

  • x
  • y
  • opacity (optional)
  • fill (optional)
  • stroke (optional)
  • strokeWidth (optional), strokeStyle (optional) - to control the width of the line series and whether they are dashed or solid.
  • color (optional, used instead of fill and stroke if none of them is passed)
  • size (optional)

If the property is not passed in any of the objects, the property is not visualized. The user can override the way how properties are visualized by passing custom range, domain or type of scales to the series or the entire chart (please see Series for more info).

Not all properties can be visualized in each series. Here's a short comparison of them:

x y color opacity size
LineSeries + + +
AreaSeries + + +
LineMarkSeries + + + + +
MarkSeries + + + + +
VerticalBarSeries + + + +
HorizontalBarSeries + + + +
VerticalRectSeries + + + +
HorizontalRectSeries + + + +
HeatmapSeries + + + +

API Reference

XYPlot

XYPlot is a component that wraps series, axis and grids, hints, etc and seamlessly provides necessary dimensions, sizes and scales into its children.
XYPlot may or may not contain axes, grids, hints, crosshairs or series.

width

Type: number
Width of the chart. The width should be passed.

height

Type: number
Height of the component. The height should be passed.

className (optional)

Type: string
DOM classNames to be added to the wrapper component.

margin (optional)

Type: Object
Default: {left: 40, right: 10, top: 10, bottom: 40} Margin around the chart.

stackBy (optional)

Type: string
Stack the chart by the given attribute. If the attribute is y, the chart is stacked vertically; if the attribute is x then it's stacked horizontally.

<XYPlot
  stackBy="y"
  width={300}
  height={300}>
  <LineSeries
    data={[
      {x: 1, y: 10},
      {x: 2, y: 5},
      {x: 3, y: 15}
    ]}/>
  <LineSeries
    data={[
      {x: 1, y: 12},
      {x: 2, y: 21},
      {x: 3, y: 2}
    ]}/>
</XYPlot>

NOTE in order to stack properly react-vis expects each x value in each series to be present (assuming stackBy: 'x', the same applies to stackBy 'y', just transposed). To wit, if our data looks like

const seriesOne = [
  {x: 1, y: 10},
  {x: 3, y: 15}
];

const seriesTwo = [
  {x: 1, y: 10},
  {x: 2, y: 5},
  {x: 3, y: 15}
];

const seriesThree = [
  {x: 3, y: 15}
];

would render weirdly (eg boxes would not lump together at the bottom of the chart). To avoid this, simply provide zeroes for empty cells

const seriesOne = [
  {x: 1, y: 10},
  {x: 2, y: 0},
  {x: 3, y: 15}
];

const seriesTwo = [
  {x: 1, y: 10},
  {x: 2, y: 5},
  {x: 3, y: 15}
];

const seriesThree = [
  {x: 1, y: 0},
  {x: 2, y: 0},
  {x: 3, y: 15}
];

Will render beautifully!

onMouseLeave (optional)

Type: function()
The function that is triggered each time the mouse leaves the component.

onMouseMove (optional)

Type: function()
The function that is triggered each time mouse moves over at the component.

onMouseEnter (optional)

Type: function()
The function that is triggered each time the mouse enters the component.

animation (optional)

Type: {duration: number}|boolean Default: false
Animation config, which is automatically passed to all children, but can be overrided for the each child.
If false is passed, then the child components will not be animated.
If true is passed then the child components will be animated with the default settings.
If an object is passed, then the child components will be animated with the given settings.
