Dear all
I would like to plot a Gantt chart type plot, but with more than one
colour on a line. The gantt.chart function will allow me to add more
than one bar on a line, but it is in the same colour as the first bar
on that line. For example (using the code helpful provided in the R
graphics gallery)
require(plotrix)
Ymd.format <- "%Y/%m/%d"
Ymd <- function(x){ as.POSIXct(strptime(x, format=Ymd.format))}
gantt.info <- list(
labels =c("First task","Second task","Third task","Fourth
task","Fifth task","First task"),
starts
=Ymd(c("2004/01/01","2004/02/02","2004/03/03","2004/05/05","2004/09/09",
"2004/09/01")),
ends
=Ymd(c("2004/03/03","2004/05/05","2004/05/05","2004/08/08","2004/12/12",
"2004/09/10")),
priorities =c(1,2,3,4,5,5))
gantt.chart(gantt.info,main="Calendar date Gantt chart")
Both bars in the first line are red=priority level 1, rather than one
red (level 1) and one purple (level 5)
Am I missing some simple option in the gantt.chart function, or do I
have to program the chart another way?
Many thanks for any assistance,
Kind regards
DD
