R help - Nov 2010 - help cannot put multiple chart Stacked Bar (from PerformanceAnalysis library) in a single plot

Hi

I'm having problems displaying multiple chart.StackedBar from 
PerformanceAnalysis library on a  single plot. I've tried using 
par(mfrow=c(2,1)) but that doesn't work.

If I do it with barplot(), it works fine and I see both plots on a single plot.
> plot(mfrow=c(2,1))
> barplot(blahblah)
> barplot(blahblah)
However if I try to use chart.StackedBar, the second entry appears to just 
overwrite the window.
> plot(mfrow=c(2,1))
> chart.StackedBar(blahblah,date.format="%H:%M:%S",las=2, 
>colorset=rainbow12equal)
> chart.StackedBar(blahblah,date.format="%H:%M:%S",las=2, 
>colorset=rainbow12equal)
Any suggestions are greatly appreciated!
