changes size of subgroup totals from gchart vbar

[barbier]

Hello,

I make a bar chart by proc gchart vbar with subgroups. The grouptotals are written in the bars (clipref). They are printed very small. I am looking for a way to make them bigger.

I have tried 'goptions htext = ...' but this affects only the letters at the x-axis. There is no effect on the numbers in the graph.

How can I adapt the size of the numbers within the graph?

thanks

Sara
