<div>Brian,</div>
<div> </div>
<div>Thank you for you answer.</div>
<div> </div>
<div>Here enclosed the result I would like to get (levelplot.jpg) and an example of input file (CPU.csv, reflecting date as M/DD/YYY hh:mm and CPU as %).</div>
<div> </div>
<div>So what I would like to have is a matrix with x = minutes within a day (here with a 30min interval) and y = days of the month, and colors plotted in this frame to reflect the CPU usage level.</div>
<div> </div>
<div>but... well, I' ve tried and tried this morning, but I cannot show anything... my ideas are too stupid (trust me, I spend time on this, I'm not looking for a ready-to-use piece of code).</div>
<div>After further testing, I think I should forget this idea : I am not enough aware of the lattice package to go this way... too many settings that I don't know.</div>
<div>I'm afraid won't be able to do it alone.</div>
<div> </div>
<div>So if someone has simple ideas or documentation for me to start building this solution, I will appreciate, but if you consider this is too complex for a lattice-beginner, I will understand.</div>
<div> </div>
<div>I any case, thank you very much for having taken time to answer me.</div>
<div> </div>
<div>Best regards,</div>
<div> </div>

<br>It will be difficult for people to help you if you don't provide a reproducible example.<br><br>I also suggest emailing the package maintainer, and possibly r-help, if what I've suggested above doesn't resolve the problem for you.<br>

<div class="h5">Hello to all,<br><br>I am sorry for disturbing you, but I really don't know where/who to ask...<br>so if this distribution list is not dealing with my concern, please excuse<br>me...<br><br>Here is my concern : I am trying to do a levelplot as in Holtman, 2005<br>
(Visualization techniques for analysing patterns in system performance<br>data), to display CPU usage according to the day of the month (y) and<br>minutes (x).<br><br>I am familiar with R basic features, but not at all with lattice package and<br>

such a plot ? (which is nothing new : the plot I'm dreaming of is the<br>Holtman's levelplot !).<br><br>Thank you very much, and excuse-me if I'm not addressing the right<br>distribution list.<br><br>Best regards,<br>
