R help - Jan 2005 - axis placement with stacked barplots and the asp=1 parameter

Hi,

I'm currently using barplot to generate vertically stacked bar charts.
I'd like to be able to use the "asp=1" parameter with barplot(),
but
doing this causes the y axis to be placed on the far left as shown in
the attachment demo.pdf.

I could get around this by using the negative values for the line
parameter of the axis() function. I'd rather not do this and imagine I'm
doing something wrong. Any help would be much appreciated.

Thanks
Kav

See the posting guide, some file types (including pdf) will be omitted 
from your messages to R-help. You might want to specify a short but 
easily reproducible examples in 2-5 lines of code.

Why do you want to use "asp" with a barplot???

Hi

Here's some example code which illustrates the issue:

dataSeries<-array(0, c(5, 2))

dataSeries[1, 1] <- 5
dataSeries[2, 1] <- 5
dataSeries[3, 1] <- 0
dataSeries[4, 1] <- 2
dataSeries[5, 1] <- 0

dataSeries[1, 2] <- 7
dataSeries[2, 2] <- 0
dataSeries[3, 2] <- 0
dataSeries[4, 2] <- 0
dataSeries[5, 2] <- 1

barplot(dataSeries, asp=1)

Removing the asp=1 parameter produces a correct looking plot. I need to
use the asp=1 parameter because I was re-writing the barplot function to
create stacked charts with rounded corners (instead of rectangles). For
the arc at the corners of the bars to look correct I need asp=1. I've
attached a .ps file to show you what I was trying to achieve.

Thanks
Kav
