The Angular Smith Chart is a control for showing the parameters of transmission lines in high-frequency circuit applications. Its rich feature set includes features like legends, markers, tooltips, and data labels.

Rendering type

Visualize both the impedance and admittance of transmission lines with Smith chart.

Title and subtitle

Add a title and subtitle to the JavaScript Smith chart control to visualize additional information about the data represented. You can customize the font and alignment of the title and subtitle.

Multiple series

Plot any number of line series for representing data.

Axis customization

The Angular Smith chart control supports a horizontal axis and radial axis. The horizontal axis is used for plotting resistance values of transmission lines and the radial axis is used for plotting nonresistance values of transmission lines.

Markers highlight data points to improve readability.

Data labels

Easily annotate the data points with labels to help improve the readability of data. The data labels in the Angular Smith chart control are smartly arranged to avoid intersection when there are large amounts of data.

A legend provides additional information that is helpful in identifying individual series in a Smith chart. It can be docked at the left, right, top, or bottom positions around the plot area. By clicking a legend item, we can toggle series visibility.

import { Component } from '@angular/core';

    selector: 'app-container',
    template: `<ejs-smithchart style='display: block;' id='container' height='350px'>
        <e-series [dataSource]='seriesdata1' name='Transmission1' reactance='reactance' resistance='resistance'> </e-series>
        <e-series [points]='seriespoints' name='Transmission2'> </e-series>

export class AppComponent {
    public seriesdata1: object[] = [
                { resistance: 10, reactance: 25 }, { resistance: 8, reactance: 6 },
                { resistance: 6, reactance: 4.5 }, { resistance: 4.5, reactance: 2 },
                { resistance: 3.5, reactance: 1.6 }, { resistance: 2.5, reactance: 1.3 },
                { resistance: 2, reactance: 1.2 }, { resistance: 1.5, reactance: 1 },
                { resistance: 1, reactance: 0.8 }, { resistance: 0.5, reactance: 0.4 },
                { resistance: 0.3, reactance: 0.2 }, { resistance: 0, reactance: 0.15 },
    public seriespoints: object[] = [
                { resistance: 20, reactance: -50 }, { resistance: 10, reactance: -10 },
                { resistance: 9, reactance: -4.5 }, { resistance: 8, reactance: -3.5 },
                { resistance: 7, reactance: -2.5 }, { resistance: 6, reactance: -1.5 },
                { resistance: 5, reactance: -1 }, { resistance: 4.5, reactance: -0.5 },
                { resistance: 3.5, reactance: 0 }, { resistance: 2.5, reactance: 0.4 },
                { resistance: 2, reactance: 0.5 }, { resistance: 1.5, reactance: 0.5 },
                { resistance: 1, reactance: 0.4 }, { resistance: 0.5, reactance: 0.2 },
                { resistance: 0.3, reactance: 0.1 }, { resistance: 0, reactance: 0.05 },
