I tried with org.eclipse.birt.chart.model.layout.impl.LegendImpl setText, setLabel
and as per suggestion here https://www.eclipse.org/forums/index.php/t/243291/

For HTML5 charts, write client scripts in the chart editor (see attached example). The Highcharts API can be found here: https://api.highcharts.com/highcharts/
