Thx for the details Josh! You're right - I meant performance analytics. I'm about 4 weeks into R now so I'm a bit of a noob. I've downloaded the source to see what you're talking about. I'll play around with it.
The data is pretty straight forward and has something like this: date,bucket,view,db "2010-10-31 04:44:44",10,11,12 "2010-10-31 04:44:45",13,14,15 ... ... contained in a csv file. I convert the class of data into xts prior to passing it into chart.StackedBar. -Patrick On Nov 9, 2010, at 1:56 PM, Joshua Wiley <jwiley.ps...@gmail.com> wrote: > On Tue, Nov 9, 2010 at 12:41 PM, patrick nguyen > <patrickqngu...@yahoo.com> wrote: >> Hi >> >> >> I'm having problems displaying multiple chart.StackedBar from >> PerformanceAnalysis library on a single plot.
