[gradsusr] Help: How to customize contour label in GrADS?

[얍준후이]

Hi Jennifer,
 
I  query the shade info and read the contour level and try to 'set clab 'calender
 
*calender is a variable which gives the julian date
 
As the result is obvious, it will only print the last string at the end of the loop.
 
Am I doing it wrong?
 
Regards
JH

You can use 'set clab FOO' and it will draw a label as "FOO". I guess you could draw each contour individually, looping over the contour level, convert the level from julian day to a string, then label that contour appropriately.

Hi Jennifer,

I think JH Yap wants to get a contour label with something like, for example, "21JAN" instead the julian day 21, and so on. His contour levels are julian days. I guess it is kind of difficult to do, if not impossible. That is, to get julian days as contour levels in a map, certainly it comes from a matrix of data composed by julian days, one julian day (a number) for each grid point. How to get the same information using a "string" date? The problem here is that contours, in GrADS, comes from numbers, through a process of interpolation (numbers again), not from strings. How to interpolate "strings"?

Maybe JH Yap could give us an example of contour label he wants, just to clarify a bit more.

Are you interesting in changing the contour labels or the axis labels? For contour labels, 'set clab' is the most general, and 'set clopts' and 'set clskip' control their appearance. For axis labels, most of the controls do not apply to a date/time axis, so you have to override manually with 'set xlabs'. --Jennifer

Hi GrADS team,  I have displayed my contour by default like this  ga-> set gxout contourga -> d flowersContouring: 80 to 145 interval 5   Then I get my contour presented in map as per the image attached.  The contour label is julian date.    Now I would like to change the contour label to regular date.  I already made a function for julian date to regular date conversion in GrADS script language.  How could I customize the default contour label (julian date) to regular date by using my function?
