When plotting against time that is in YYYYMM/YYYYMMDD/YYYYMMDDHH type of format, it is best to use one of our "yyyymmxxx_to_yyfrac" routines to create a fractional year array, and then you can plot against this array.

When plotting two curves in the same space that have different ranges, you have to be very careful about setting the trX/Y/Min/MaxF resources. NCL is effectively taking two individual XY plots and drawing them on top of each other, so if you change the trYMaxF for one and not the other, then the curves from both plots are not going to be quite lined up properly. I fixed this by setting these values to the actual min/max of your data.</span><br></div><div style="font-size:small"><br></div><div style="font-size:small">5. Since your prec array has a lot of isolated values, it might be best plotted as a series of markers (resR@xyLineMode = "Markers") instead of curves. When you plot curves, you will not see the single isolated values. You can also plot as both markers and curves (resR@xyLineMode = "MarkLines")</div><div style="font-size:small"><br></div><div style="font-size:small">See the attached script.</div><div style="font-size:small"><br></div><div style="font-size:small">--Mary</div><div style="font-size:small"><br></div></div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small"><br></div></div></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Oct 2, 2018 at 3:05 AM, Ehsan Taghizadeh <span dir="ltr"><<a href="mailto:ehsantaghizadeh@yahoo.com" target="_blank">ehsantaghizadeh@yahoo.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5"><div><div style="font-family:bookman old style,new york,times,serif;font-size:16px"><div style="font-family:bookman old style,new york,times,serif;font-size:16px"><span><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">Hi,</div><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">I tried to plot something like "requested.png" in attached files.
