Hi DP,<br>
<br>
if you read the following two examples pages you should be able to
read and plot your ASCII file.<br>
<br>
See xy-plots example page: <a class="moz-txt-link-freetext" href="http://ncl.ucar.edu/Applications/xy.shtml">http://ncl.ucar.edu/Applications/xy.shtml</a><br>
See Read ASCII: <a class="moz-txt-link-freetext" href="http://ncl.ucar.edu/Applications/read_ascii.shtml">http://ncl.ucar.edu/Applications/read_ascii.shtml</a><br>
<br>
But here is a short script to do it:<br>
<br>
<font color="#3333ff"><tt> fname = "tst1.txt"</tt><tt><br>
</tt><tt><br>
</tt><tt> nrow = numAsciiRow(fname)</tt><tt><br>
</tt><tt> data = asciiread(fname,-1,"string")</tt><tt><br>
</tt><tt> date = str_get_field(data(1:),1," ")</tt><tt><br>
</tt><tt> pressure = toint(str_get_field(data(1:),2," "))</tt><tt><br>
</tt><tt> wind = toint(str_get_field(data(1:),3," "))</tt><tt><br>
</tt><tt><br>
</tt><tt> idate = ispan(0,dimsizes(date)-1,1)</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> wks = gsn_open_wks("x11","plot_tst1")</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> res = True</tt><tt><br>
</tt><tt> res@trXMinF = idate(0)</tt><tt><br>
</tt><tt> res@trXMaxF = idate(nrow-2)</tt><tt><br>
</tt><tt> res@trYMinF = -100</tt><tt><br>
</tt><tt> res@trYMaxF = max(pressure)+100</tt><tt><br>
</tt><tt> res@tmXBMode = "Explicit"</tt><tt><br>
</tt><tt> res@tmXBValues = idate</tt><tt><br>
</tt><tt> res@tmXBLabels = date</tt><tt><br>
</tt><tt> res@tmXBLabelAngleF = 45</tt><tt><br>
</tt><tt></tt><tt><br>
</tt><tt> plot = gsn_csm_xy(wks,idate,(/pressure,wind/),res)</tt></font><br>

have a text file containing date minimum pressure and wind
speed, which I need to plot as an XY plot with the two
variables with time as the x-axis. I tried according to the
examples given in NCL examples but am not able to produce it.
So if anyone can help me in this regard I will be much
grateful.</div>
