Bar chart & Category (x) axis labels
 

If you make a bar chart in Excel 2003, and have two
columns of text as Category (x) axis labels, the first
column is shown vertical and the text in the second column
is shown horizontal in the chart.

If you open/make the same chart in Excel 97, the text in
both columns is shown horizontal.

If there is a lot of text, it becomes unreadable when it's
vertical.
Is this by design or can it be fixed somehow?
