Timeline rowLabelStyle

[guerai]

Dear all

I am using Timeline I need to fix the size of the row Label, as example 200px

someone known if is possible to set a fixes size using rowLabelStyle?

At this moment I'm trying to do this,

 colors: ['#cbb69d', '#603913', '#c69c6e'],
      timeline:{ groupByRowLabel: true,
                 colorByRowLabel: false,
                  rowLabelStyle: {fontName: 'Helvetica',  color:'#BBBBBB',fontSize:'24',  width:'200px'}, 
           }
    };

But it does not works

thanks for your time
