        title : {
        text: 'Impedance Transmission',
        subtitle: {
            text: 'Transmission'
        }
    },
        dataSource: [
                 { resistance: 10, reactance: 25 }, { resistance: 8, reactance: 6 },

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.
