Plotting a count process

Thank you for your advice, but this is not the exaxt thing i'm looking for
http://robotics.caltech.edu/~zoran/Research/poisson/img1.png
this picture gives an example what i want to get. instead of t0, t1, 
t2,.... i want to draw my dates.
In my description i forgot the the horizontal line, which indicates the 
time between two dates each, sorry for that.

regards
andreas

i want to plot a count process in the following way, but i don't know
how i can do that. i have data for example x<-(0,2,6,2,8,4,.....) and
dates y which is a vector of weekly dates for example
(01/01/06, 08/01/06, 15/01/06, 22/01/06, ....), now i want to plot the
y's an the horizontal axis. On each date the count process jumps upwards
1 unit, so the vertical axis is 0, 1, 2, 3, ......
the distance between the dates is shown in vector x, so for example the
distance between 08/01/06 and 15/01/06 should be 2. maybe i can use some
times series functions for doing this?

  

     

If I understand you correctly, this means plotting equidistant point against 
the cumulative sum. Forgetting about the dates now, this would do it.

x = floor(pmax(rnorm(30,5,2),1))
xcum = cumsum(x)
plot(xcum,1:30)
