About profiling xen
Hi there,
I am getting very low throughput (around 0.29Mbps) while running netperf benchmark for guest to guest communication on a single physical host. To analyse where the time is spent in hypervisor I wanna use profiling. Please help me choosing good profiler according to my requirments. Should it be better in my case, Xentrace, gprof, xenoprof or Oprofile. Is it possible to use some vtune

axis tick colors: only one value allowed?
Hi,
So far as I can tell, the 'col.ticks' parameter for axis() only uses the
first value provided. E.g.:
plot(0:1,0:1, col.ticks=c('blue','red','green')) #all ticks are blue
Just wondering if there's a different option in the basic plot commands
that can handle multiple colors, and also whether ggplot and/or lattice
allow for multiple tick colors.

axis and tick widths decoupled (especially in rugs!)
Hi!
(a complete newby, but will not give up easily!)
I was wondering if there is any way to decouple the axis and tick mark
widths? As I understand they are both controlled by the lwd setting, and
cannot be controlled independently? For example I might want to create major
and minor ticks, which I now know how to do by superimposing two axes with
different at settings, but what if I also wanted

problem with tick graph
Dear all,
I'm having problems with the tick of my graph. I'mpcombining lines and
barplot.
For my I'm using the function axis combined with the function pretty to have
more efficient tick, but all my tick (for example, 300 as my max tick and -100
as my min tick) are not printed on my graph.
So I would like to have for the left axis the seq from 0 to 100 (with 0 and
100 printed on

Axis line not appearing with axis(tick=FALSE) (PR#8998)
Full_Name: Sean Pieper
Version: 2.3.1
OS: Windows
Submission from: (NULL) (67.188.92.37)
Hi, I am trying to create a qualitative figure for which I don't want tick marks
or numbers, but having some axes would be nice.
If I do:
plot.new()
axis(2,labels=FALSE,tick=FALSE,lty="solid",lwd=1)
I expect this should give me a vertical line on the left edge of the plot, but

[lattice] Increase distance between tick labels and ticks in wireframe plot ("pad")
Hello,
I try to increase the distance between tick labels and ticks in a lattice wireframe plot. Here's a minimal example:
## Minimal example
x <- y <- z <- c(1,2,3)
df <- data.frame(x, y, z)
wireframe(z ~ x*y, df, scales = list(arrows = FALSE, col = "black", font = 1, tck=0.6))

Tick mark alignment for POSIXct data
I am using POSIXct objects to store my date/time information. If I am
plotting less that 2 days worth of data, I get the correct tick marks on the
x-axis which is showing the 'day HH:MM' and these line up with the data
points.
If the data spans more than 2 days, the tick marks are now off. In the data
below, I am creating some sample data and plotting the points. I am in the

tick marks and layout
Hi, all.
Layout seems to put tick marks only in the leftmost column (for the y
axis) and bottom row (for the x axis). This is easy to see using the
following trivial program:
function (nr, nc) {
layout(matrix(1:(nr * nc), nr, nc))
for (i in 1:(nr * nc)) {
plot(rnorm(10), rnorm(10))
}
layout(matrix(1, 1, 1))
}
I'd like to be able to override this behavior and

control of scat1d tick color in plot.Predict?
Hi All,
I have a quick question about using plot.Predict now that the rms package
uses lattice. I'd like to add tick marks along the regression line, which
is given by data=llist(variablename) in the plot call. The ticks show up
fine, but I'd like to alter the color. I know the ticks are produced by
scat1d, but after spending a fair bit of time going through documentation,

How to hide tick lines behind the "box-and-whisker" 's in a boxplot
Dear R people,
I wonder how to hide tick lines behind other figures in a plot, e.g.
in a boxplot.
# Sample code:
x<- c(rep(4,50),rep(5,20),rep(6,50),rnorm(20,5,1))
boxplot(x)
axis(2,tck=1,col.ticks='grey',lty=5 )
# end of sample code
The tick lines is put on top of the box-plot, but I would like to put
these lines behind the box and whiskers..

Align periodic vpts to reduce timer interrupts and save power
Hi,
After c/s 18694 changed vHPET to vpt, for single HVM RHEL 5u1 guest idle case, our box will consume ~0.8W more power than before. The reason is two periodical vpts'' expires are hard to be aligned in the 50us soft timer SLOP. So we are considering a vpt specific enhancement which could try to just align periodical timers within vpt.
A generic enhancement is to add a new interface

minor tick marks
Hi !
I need a plot for data extending over several orders of magnitude on the y axis.
The following command generates a nice looking semi-log plot for my data:
plot(x,y,log="y",type="l",lty=3, ylim=c(0.01,2),yaxp=c(0.01,1,1),las=1)
I would appreciate having also minor tick marks in-between the 3 major ticks obtained with the above command. The "minor.tick" function

Wishlist: more flexible handling of tick labels in axis.Date (PR#7914)
I think allowing the user to change the labels is a good idea, but have
some nitpicking about the details.
- Could you grab a copy of the current axis.Date source from
https://svn.r-project.org/R/trunk/src/library/graphics/R/datetime.R
and edit that, rather than what you see in R? There are some comments
in the source that shouldn't be lost. This will also mean that it's

Plot: Distance between tick and tick label on y-axis

I want to reduce the distance between my ticks and their labels. I managed
