Implementing Syncfusion React Smith Charts

A comprehensive skill for implementing and customizing Syncfusion React Smith Chart component. Smith Charts are specialized diagrams used in electrical engineering and RF design to visualize impedance, reflection coefficients, and transmission line parameters.

When to Use This Skill

Use this skill when you need to:

• Visualize transmission line impedance and reflection data
• Plot RF circuit parameters (S-parameters, impedance matching)
• Display resistance and reactance relationships
• Create interactive Smith Charts with markers and tooltips
• Implement electrical engineering data visualizations
• Configure Smith Chart axes (horizontal and radial)
• Add legends, data labels, and annotations
• Export Smith Charts for documentation or reports
• Ensure accessibility compliance for technical charts

Component Overview

The Syncfusion React Smith Chart is a specialized charting component that:

• Plots data points with resistance and reactance coordinates
• Supports multiple series with customizable styling
• Provides horizontal and radial axis configurations
• Includes interactive features (tooltips, legends, markers)
• Offers print and export capabilities (PNG, JPEG, SVG, PDF)
• Ensures WCAG 2.2 accessibility compliance
• Supports responsive sizing and theming

Quick Start Example

import * as React from 'react';
import { SmithchartComponent, SeriesCollectionDirective, SeriesDirective, Inject, SmithchartLegend, TooltipRender } from '@syncfusion/ej2-react-charts';

function App() {
  const transmissionData = [
    { resistance: 0, reactance: 0.05 },
    { resistance: 0, reactance: 0.1 },
    { resistance: 0, reactance: 0.2 },
    { resistance: 0.3, reactance: 0.3 },
    { resistance: 0.5, reactance: 0.4 },
    { resistance: 1.0, reactance: 0.5 }
  ];

  return (
    <SmithchartComponent
      id="smithchart"
      title={{ text: 'Transmission Line Impedance' }}
      legendSettings={{ visible: true }}
    >
      <Inject services={[SmithchartLegend, TooltipRender]} />
      <SmithChartSeriesCollectionDirective>
        <SmithChartSeriesDirective
          name="Transmission1"
          points={transmissionData}
          marker={{ visible: true }}
          tooltip={{ visible: true }}
        />
      </SeriesCollectionDirective>
    </SmithchartComponent>
  );
}

export default App;

Common Patterns

Multiple Series with DataSource

const series1Data = [
  { resistance: 0, reactance: 0.05 },
  { resistance: 0.3, reactance: 0.2 },
  { resistance: 1.0, reactance: 0.4 }
];

const series2Data = [
  { resistance: 0.1, reactance: 0.1 },
  { resistance: 0.5, reactance: 0.3 },
  { resistance: 1.5, reactance: 0.5 }
];

<SmithchartComponent legendSettings={{ visible: true }}>
  <Inject services={[SmithchartLegend]} />
  <SmithChartSeriesCollectionDirective>
    <SmithChartSeriesDirective
      name="Line 1"
      dataSource={series1Data}
      resistance="resistance"
      reactance="reactance"
      fill="blue"
    />
    <SmithChartSeriesDirective
      name="Line 2"
      dataSource={series2Data}
      resistance="resistance"
      reactance="reactance"
      fill="red"
    />
  </SeriesCollectionDirective>
</SmithchartComponent>

Customized Markers and Labels

<SmithChartSeriesDirective
  name="Impedance Data"
  points={data}
  marker={{
    visible: true,
    height: 10,
    width: 10,
    shape: 'Diamond',
    fill: 'green',
    dataLabel: {
      visible: true,
      textStyle: { color: 'black', size: '10px' }
    }
  }}
/>

Export to Image

import { useRef } from 'react';

function ChartWithExport() {
  const chartRef = useRef(null);

  const exportChart = () => {
    chartRef.current.export('PNG', 'smithchart');
  };

  return (
    <>
      <button onClick={exportChart}>Export as PNG</button>
      <SmithchartComponent ref={chartRef} id="smithchart">
        {/* series configuration */}
      </SmithchartComponent>
    </>
  );
}

Required Module Injections

import { SmithchartLegend, TooltipRender } from '@syncfusion/ej2-react-charts';

<Inject services={[SmithchartLegend, TooltipRender]} />

• SmithchartLegend: Required for legend functionality
• TooltipRender: Required for tooltip display

Troubleshooting Guide

Chart Not Rendering

• Verify @syncfusion/ej2-react-charts package is installed
• Ensure CSS theme is imported in your app
• Check that data has valid resistance and reactance fields
• Confirm container has defined dimensions

Legend Not Showing

• Verify legendSettings.visible is set to true
• Ensure SmithchartLegend module is injected
• Check that series have name property defined

Tooltips Not Working

• Confirm TooltipRender module is injected
• Verify tooltip.visible is true on series
• Check that mouse hover events are enabled

Data Not Displaying

• Validate data format: array of objects with resistance/reactance
• Check field names match dataSource property configuration
• Ensure numeric values are valid (not NaN or undefined)
• Verify series visibility is not set to false

Export Fails

• Confirm chart has a valid id property
• Check export format is supported (PNG, JPEG, SVG, PDF)
• Ensure export method is called on mounted component reference

Styling Issues

• Import correct Syncfusion theme CSS file
• Check that custom styles don't conflict with component classes
• Verify width/height properties are properly formatted
• Ensure container styling allows chart to render
