Dynamicreports: Remove black border wrapped legend

Question

I am using dynamicreports4.1.1

When I draw barCharts, I want to remove the black border wrapped the legend,

but not remove the total legend.

I tried to customize the chart render but failed, I can't find what properties it use.

Answer 1

LegendTitle legend = chart.getLegend();

    //necessary when some set showLegend=false
    if(legend!=null){
        legend.setFrame(BlockBorder.NONE);//去除legend的黑线框
    }
