React Scatter Graph

A fully customizable, ready to use scatter graph UI package for React. Try tweaking React Scatter Graph using this codesandbox link here

Installation

npm install @keyvaluesystems/react-scatter-graph

You’ll need to install React separately since it isn't included in the package.

Usage

React Scatter Graph can run in a very basic mode like this:

import React, { useState } from 'react';
import ReactScatterGraph from '@keyvaluesystems/react-scatter-graph';

function App() {
  data = [
    { x: 450, y: 150 },
    { x: 360, y: 330 },
    { x: 650, y: 315 },
    { x: 270, y: 200 }
  ];

  return <ScatterGraph data={data} graphHeight={500} />;
}

export default App;

The data array is an array of objects with { x, y } coordinates.

Note: The graph width is responsive. So it can be adjusted by a parent wrapper. You need to provide the height.

React Scatter Graph for date inputs:

Scatter graph is a useful tool for plotting date values. In order to do so, timestamps must be provided for the x-axis values.

import React, { useState } from 'react';
import ReactScatterGraph from '@keyvaluesystems/react-scatter-graph';

function App() {
  data = [
    // x given in milliseconds corresponding to the date
    { x: 1672876800000, y: 150 },
    { x: 1673568000000, y: 330 },
    { x: 1674086400000, y: 315 },
    { x: 1673222400000, y: 200 }
  ];

  return <ScatterGraph data={data} graphHeight={500} />;
}

export default App;

Breaking Changes

• The axisColor prop has been renamed to gridLineColor.

Migration Steps

• Update Prop: Replace the prop axisColor with the name gridLineColor.

Before

<ScatterGraph data={data} graphHeight={500} axisColor='#00FF00' />

After

Props

Props that can be passed to the component are listed below:

Prop	Description	Default
data: object[]	An array of x-y coordinates to render.	undefined
graphHeight: number	Height of graph in pixel	undefined
gridLineColor: string	Color for the grid lines on the x and y axes. It helps user to see the exact value of a point on the graph	#9E9E9E
originAxisColor: string	Color for the origin axis	#9E9E9E
renderYLabel?: (arg: number | string): string	Render function for customizing Y axis label	undefined
renderXLabel?: (arg: number | string): string	Render function for customizing X axis label	undefined
scatterPointColor?: (arg: { x: number, y: number }): string	Function for customizing scatter point color. Based on the args, we can customise the color. Return value should be the color hash / string.	undefined
renderValuebox?: (x: number, y: number): ReactElement	Render function for customizing the value box shown on hover.	undefined
styles?: object	Provides you with a bunch of style objects and callback functions to override the default styles.(refer Style Customizations)	undefined

Style Customizations

Style customizations can be done by overriding default styles using the styles prop. The below code shows all the overridable styles using styles prop.

<ScatterGraph
  data={data}
  graphHeight={500}
  styles={{
    Root?: {...styles},
    XLabel?: (xLabel) => ({...styles}),
    YLabel?: (yLabel) => ({...styles}),
  }}
/>;

For a more specific example, please refer the following:

<ScatterGraph
  data={data}
  graphHeight={500}
  styles={{
    Root: {
      marginTop: 50
    },
    XLabel: () => ({
      color: 'blue'
    }),
    YLabel: () => ({
      color: 'green'
    })
  }}
/>

Within the styles prop, following keys accept a style object:

• Root - overrides the style of outermost container.

Within the styles prop, following keys accept a function that returns the desired style for each element:

• XLabel - overrides the style of x-axis labels.
• YLabel - overrides the style of y-axis labels.
