Re: [las_users] Vector plots



What a dummy I am!  I forgot that the problem with XSKIP, YSKIP was a current trac ticket.  Ansley would be better able than I to follow up on when a fix might be available and whether you can get a copy of the corrected script in advance.

    sorry for the booboo - Steve

    Hi Steve,

Thank you for the response.
But I tested the xskip and yskip on Option panel, and there is no effect. You can try that on http://las.aviso.oceanobs.com/ with geostrophic velocities.
Here is a part of ferret script used by the LAS to generate the plot (in debug log file) :

    DEFINE SYMBOL qualifiers = ($qualifiers)/XSKIP=`xs`/YSKIP=`ys`
!-> DEFINE SYMBOL qualifiers =  /XSKIP=100/YSKIP=100
ENDIF
! Set up for degrees-minutes-seconds labels on axes with units of degrees
IF ($ferret_deg_min_sec"0|false>0|*>1") THEN GO LAS_set_deg_min_sec.jnl
!-> IF 0 THEN GO LAS_set_deg_min_sec.jnl
! Do the plot
VECTOR($qualifiers)/TITLE="($ferret_plot_title)"/SET ($ferret_vector_1), ($ferret_vector_2)
!-> VECTOR/XSKIP=100/YSKIP=100/TITLE="V (Meridian Velocity (cm/s)) (cm/s), V (Meridian Velocity (cm/s)) ((cm/s))"/SET grid_0001[d=1,X=-180:180,Y=-82:81,T="14-Oct-1992 00:00:00":"14-Oct-1992 00:00:00"], grid_0002[d=1,X=-180:180,Y=-82:81,T="14-Oct-1992 00:00:00":"14-Oct-1992 00:00:00"]
   IF ($xform_dms"0|*>1") THEN PPL XFOR (($xform_dms))
!-> IF 0 THEN PPL XFOR ( )
   IF ($yform_dms"0|*>1") THEN PPL YFOR (($yform_dms))
!-> IF 0 THEN PPL YFOR ( )
PPL VECTOR

So with these command there is no xskip or yskip (see image attached).
Best regards,
Tony

Hi Tony,

There should be an "xskip, yskip" option available to you on the Options panel that controls this.  I believe you can set a default for it in the LAS configuration XML.

With regard to Ferret if you use the /set_up qualifier, then you'll need to issue the "skip" options on the PPL VECTOR command that follows.  This is discussed under the VECTOR/SET_UP option in the Users Guide (http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/commands-reference/VECTOR%20)

    Re-re-hi,

I still have problem for the vector plot, like with old LAS. The plot contain arrows on all gridded point, without skipping points.
The result is attached. How can I do for that ?
I saw that with ferret, if you do the plot with vector command with /set_up it's the same bug, without set-up it's ok.
Sorry for the number of mail I post today...
Best regards,
Tony
