Font Bold on series labels

To make the series labels bold I wrote

 

Me.Chart.Axis.X.Labels.SeriesLabels.Font.Style.Bold = True

but this isn’t working. Where am I going wrong? Some help please

Thanks

 

 Font.Style is Read Only.

I do not know what the VB equivalent is, but in C# you have to do something like:

Me.Chart.Axis.X.Labels.SeriesLabels.Font = new System.Drawing.Font("Verdana", 9, System.Drawing.FontStyle.Bold);
