Display volume data for financial chart in React Chart.

This article explains how to display volume data for financial chart in the React Chart.

Customize to display volume data in the financial chart

Step 1: First, initialize the datasource.

financial-data.js

exports.chartValues = [
{
  period: new Date('2012-04-02'),
  open: 85.9757,
  high: 90.6657,
  low: 85.7685,
  close: 90.5257,
  volume: 660187068
},
{
  period: new Date('2012-04-09'),
  open: 89.4471,
  high: 92,
  low: 86.2157,
  close: 86.4614,
  volume: 912634864
},
{
  period: new Date('2012-04-16'),
  open: 87.1514,
  high: 88.6071,
  low: 81.4885,
  close: 81.8543,
  volume: 1221746066
},
{
  period: new Date('2012-04-23'),
  open: 81.5157,
  high: 88.2857,
  low: 79.2857,
  close: 86.1428,
  volume: 965935749
},
{
  period: new Date('2012-04-30'),
  open: 85.4,
  high: 85.4857,
  low: 80.7385,
  close: 80.75,
  volume: 615249365
},
{
  period: new Date('2012-05-07'),
  open: 80.2143,
  high: 82.2685,
  low: 79.8185,
  close: 80.9585,
  volume: 541742692
},
{
  period: new Date('2012-05-14'),
  open: 80.3671,
  high: 81.0728,
  low: 74.5971,
  close: 75.7685,
  volume: 708126233
},
{
  period: new Date('2012-05-21'),
  open: 76.3571,
  high: 82.3571,
  low: 76.2928,
  close: 80.3271,
  volume: 682076215
},
{
  period: new Date('2012-05-28'),
  open: 81.5571,
  high: 83.0714,
  low: 80.0743,
  close: 80.1414,
  volume: 480059584
},
{
  period: new Date('2012-06-04'),
  open: 80.2143,
  high: 82.9405,
  low: 78.3571,
  close: 82.9028,
  volume: 517577005
}];

Step 2: Initialize the CandleSeries, ColumnSeries, and other required properties. Afterward, bind the volume data to the yName of the column series by using the yName property. Then map the other values such as high, low, open, and close of the CandleSeries to their respective high, low, open, and close properties.

Index.js

<ChartComponent
 id="charts"     
 primaryXAxis={{
    valueType: 'DateTime',
    crosshairTooltip: { enable: true },
    majorGridLines: { width: 0 }
 }}
 primaryYAxis={{
    title: 'Volume',
    labelFormat: '{value}M',
    opposedPosition: true,
    majorGridLines: { width: 1 },
    lineStyle: { width: 0 }
 }}
 title="AAPL Historical">
 <Inject services={[CandleSeries, Tooltip, DateTime, ColumnSeries]}/>
 <SeriesCollectionDirective>
  <SeriesDirective
      type="Column"
      dataSource={chartValues}
      animation={{ enable: true }}
      xName="period"
      yName="volume"
      enableTooltip={false}
      name="Volume"
  />
  <SeriesDirective
      type="Candle"
      yAxisName="secondary"
      bearFillColor="#2ecd71"
      bullFillColor="#e74c3d"
      dataSource={chartValues}
      animation={{ enable: true }}
      xName="period"
      low="low"
      high="high"
      open="open"
      close="close"
  />
  </SeriesCollectionDirective>
</ChartComponent>

Step 3: Initialize the secondary axis in the axes property, set opposedPosition to true, and provide a name for the axis for mapping with the series.

<AxesDirective>
  <AxisDirective
      name="secondary"
      maximum={150}
      minimum={55}
      opposedPosition={true}
  />
</AxesDirective>

Step 4: Then map the secondary axis to the candle series by using the yAxisName property.

<SeriesDirective
 type="Candle"
 yAxisName="secondary"
 dataSource={chartValues}
 xName="period"
 low="low"
 high="high"
 open="open"
 close="close"
/>
