Hello users,
I've noticed a problem when creating a stacked column plot when a column
contains a negative and a positive value. e.g.
series1<-c(-1,-2, 3, 4, 5)
series2<-c( 5, -4,-3,-2, 1)
data<-rbind(series1,series2)
barplot(as.matrix(data), beside=FALSE)
In these cases (i.e. first, third and fifth columns) the plotting is not
handled correctly. Compare this output with that of:
It doesn't make sense to stack values with mixed signs, but what barplot
does appears to make sense. The first column has a bar of length -1
overplotted with a bar of length 5, which completely obscures it. What
would you expect it to do?
Duncan Murdoch
barplot(as.matrix(data), beside=TRUE)
Shouldn't the plots look the same except in the beside=FALSE scenario
the constituent bars should not be juxtaposed but instead are one on top
of the other?
Thanks for any advice!
