Hi,

When one wants to superimposes two histos as shown in the exemple
'twoscales.C', it requieres at some point a call to 'Scale()'.

But on TProfile histo, the 'Scale()' method doesnt work as on regular
histo, and so the macro is not working properly.

- Is there a way to really 'scale' a TProfile ?
- Is there an easy way to convert a TProfile into a regular TH1D histo ?

Thanx for any help.

	Yannick
