Hi Steve, Excuse me. Could you please tell me how to plot vectors along the track? Many thanks, Jian----- Original Message ----- From: "Stephen R. Guimond" <guimond@xxxxxxxxxxxxx>

Hi Jian, You have to lay a basemap down before you call the script. For example, go basemap x=180W:130W y=10N:60N 20 go polymark polygon/overlay/...

I guess Ferret cannot get the right value of "$xaxis_max" and "$xaxis_min", but I don't know why and how to solve it.LET/QUIET PLMx_correction = PLMdefault_scale*((($xaxis_max))-(($xaxis_min)))/($ppl$xlen)!-> DEFINE VARIABLE/QUIET PLMx_correction = PLMdefault_scale*(( )-( ))/ **ERROR: command syntax: PLMdefault_scale*(( )-( ))/( before ) is illegal DEFINE VARIABLE/QUIET PLMx_correction = PLMdefault_scale*(( )-( ))/ Command file, command group, or REPEAT execution aborted Thank you very much, Jian----- Original Message ----- From: "Steve Guimond" <guimond@xxxxxxxxxxxxxxxxxxxx>To: "Jian Ma" <jianma@xxxxxxxxxx> Cc: <ferret_users@xxxxxxxx> Sent: Sunday, December 31, 2006 1:24 PM Subject: Re: Fw: [ferret_users] Track dataHi, Maybe you have an older version of FERRET, but the version I am using (v5.60) has changed that line in the code (latest bug fix in 2004). I have attached the one that I am using (it works). Does not matter what format your data is in, as long as its "in" ferret. Steve ======================================================= Stephen R.
