Greetings!<br>
<br>
<br>
I am using NCL function ”mjo_wavenum_freq_season_plot” to create wave number frequency spectra. <br>
I had modified this function to make four panel plots in one page in a<br>
single call to the function (plot attached with the mail).<br>
<br>
The two vertical lines corresponding to 30 and 60 day period are <br>
labelled using “gsn_add_text”. The text 30d and 60d is written twice <br>
on this vertical line overlapping with the spectra, thereby reducing the<br>
clarity. Thus, text (30d and 60d) should be written only once at the <br>
top of the line. Please suggest resource if any, for this text to <br>
appear only once on the corresponding vertical line. <br>
<br>
To solve the above issue, I had also tried alternate method of using <br>
resource - optPlot@dayLines=(/30,60/) and use this resource in a call <br>
to function (which is modified for four panel plots in single call to function) <br>
as follows<br>
“ mjo_wavenum_freq_season_plot (wf,wf1,wf2,wf3,nameSeason(ns), pltDir, pltType, pltName, optPlot) <br>
<br>
However, after using this resource, text is not written on the two vertical <br>
lines (corresponding to 30 and 60 day). This resource may be just for <br>
plotting vertical lines and is not meant for writing text on two vertical lines.<br>
<br>
Before posting the question, i had gone through NCL-talk archives<br>
and also searched resources for “gsn_add_text”, but found none.<br>
<br>
I am using NCL version 6.4.0 on linux machine.<br>
Please help in this regard. <br>
<br>
Any suggestion would be of great help.<br>
Many thanks in advance.<br>
<br>
