import { Smithchart } from '@syncfusion/ej2-charts';
let smithchart: Smithchart = new Smithchart({
title : {
text: 'Impedance Transmission',
subtitle: {
text: 'Transmission'
}
},
series: [
{
points: [
{ 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 },
],
}
],
});

This length can be changed using the property [maximumWidth]. Also [font], [textAlignment] and [visibility] can be customized for title as well as subtitle.
import { Smithchart } from '@syncfusion/ej2-charts';
let smithchart: Smithchart = new Smithchart({
title : {
enableTrim: true,
maximumWidth: 70,
textAlignment: 'Center',
visible: true,
text: 'Impedance Transmission',
subtitle: {
text: 'Transmission',
visible: true,
textAlignment: 'Far',
enableTrim: true,
maximumWidth: 40
}
