Installation

The easiest way to use react-waterfall-chart is to install it from npm and build it into your app with Webpack.

npm install  @keyvaluesystems/react-waterfall-chart

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

Usage

React Waterfall chart can run in a very basic mode by just providing the transactions like given below:

import  WaterfallChart  from  '@keyvaluesystems/react-waterfall-chart';

<WaterfallChart
  transactions={transactionList}
/>

The transactions prop is an array of transactions with the following keys:

• label - a string to represent each transaction

• value - a number that specifies the transaction quantity

An example for transactions array is shown below:

const  transactionsList = [{
    label:  'Quarter 1, 2020',
    value:  1000
  },{
    label:  'Quarter 2, 2020',
    value:  -500
  }];

You can use barWidth prop to specify the width of each bar present in the chart. The given value will be converted to pixels (px) and applied to the chart. With the help of showBridgeLines prop, the line connecting the adjacent bars can be shown/hidden. showFinalSummary can be used to display the summary as the last transaction.

<WaterfallChart
  transactions={transactionsList}
  barWidth={100}
  showBridgeLines={true}
  showFinalSummary={false}
/>

You can specify whether to show or hide the scale lines in the Y axis with the help of showYAxisScaleLines prop.

<WaterfallChart
  transactions={transactionsList}
  showYAxisScaleLines={true}
/>
