specify length of Y-axis within chart (or no tick label wrapping)

[beelzebubble]

I've got a bar chart whereby the Y-axis is running from left to right and the X-axis is running vertically, top to bottom. I've notice that on some occasisons the Tick labels associated with the X-axis will be presented in one line, but on others, some of the tick labels will be presented as two lines. For example, one tick label might be 'Overall Expenditure'. I want to specify that the tick lables are never 'broken' such that they always read:

'Overall Expenditure'

and never

'Overall
Expenditure'​

Can that be done? I'm building a macro, but if somone knows how to do it within the chart wizard, i'll figure it out. thanks.​
