ascii file, are working on daily data, and wish to plot customized time
ranges, this is a case where conceptually what you ask for sounds
simple but in reality it is not.<br><br></div><div>I have come up with an example code that (somewhat) does what you want. You will have to modify the attached script to suit your own needs. I cannot spend any more time on this. You will also have to take a close look at the coding to verify that the data is being read in and used correctly. <br></div><div><br></div><div>I
used a number of functions to parse and prepare the ascii data for
plotting: str_squeeze, str_split, str_split_csv, tofloat, toint and
sprinti. I also used cd_inv_calendar to prepare a time array that could
be used with the time_axis_labels procedure so that you would get nicer
tick mark labels. Note that you will likely need to play with
time_axis_labels somewhat to get the tick mark labels where you want
them:<br><br><a href="http://www.ncl.ucar.edu/Document/Functions/User_contributed/time_axis_labels.shtml" target="_blank">http://www.ncl.ucar.edu/Document/Functions/User_contributed/time_axis_labels.shtml</a><br><br></div><div>Finally, note that you can set the range of times to be plotted by setting stime/etime. You can plot any range of times from a few days to a few months.<br></div><div><br></div><div>I
have attached the code and an example graphic here. If you have any
further questions please respond to the ncl-talk email list and not to
me personally. That way others can see the dialog and can assist.<br></div><div>Good luck,<br></div>Adam </div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Tue, Mar 24, 2015 at 8:45 AM, Hesham Afify <span dir="ltr"><<a href="mailto:algocomp@gmail.com" target="_blank">algocomp@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr"><div style="font-size:large">Hi All</div><div style="font-size:large">I have some observational daily data for a couple of years, this data have many changes in regularity by the mean it toke on daily, one per three days, and one per six days patterns, have some missed periods.</div><div style="font-size:large">the point here that I want to plot this data and my inquiry about that is how to plot this data in daily, weekly, and monthly basis.</div><div style="font-size:large">a sample of this data is attached</div><div style="font-size:large"><br></div><div style="font-size:large">best regards</div><span><font color="#888888"><div style="font-size:large">Hesham </div><div><br></div>
