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

@Component({
imports: [
         SmithchartModule
    ],

providers: [TooltipRenderService, SmithchartLegendService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-smithchart style='display: block;' id='container' [title] ='title'>
    <e-seriesCollection>
        <e-series [dataSource]='seriesdata1' reactance='reactance' resistance='resistance'> </e-series>
    </e-seriesCollection>
    </ejs-smithchart>`
})

export class AppComponent {
    public title:object = {
        text: 'Impedance Transmission',
        subtitle: {
            text: 'Transmission'
        }
    }
    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 },
            ];
}

import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Title trim

Both title and subtitle of the smithchart can be trimmed if it exceeds the certain length. Trimming is enabled using [enableTrim] for title as well as subtitle. This length can be changed using the property [maximumWidth]. Also [font], [textAlignment] and [visibility] can be customized for title as well as subtitle.
