Dear Ferret Usergroup:

Am wondering if anybody here has any suggestions for me on how to get Ferret to not make duplicate time axes. I think I know what the problem is but I have not been able to solve it. The Date Columns have different Start and End Dates and this could be causing the duplicate feature.Please see attached datafile and plots to understand what I am describing.

From the datafile attached, I am trying to make two time series plots of Column 5 (right most) with Dataset 1 and 3 overlaid on the upper plot and Datasets 2 and 4 overlaid on the lower plot. I am interested in overlaying only and not any actual calculation involving the data.

The following commands is used to create the Time Axis for each dataset (begindate is a input variable in calendar date format and is from Column 2 of respective datasets. I am interested in plotting Column 5 as a function of time for all the 4 datasets. I am trying to overlay data from Dataset 1 and 3 on the upper plot and Dataset 2 and 4 on the lower plot.
All 4 datasets are vertically arranged in the file and are being read properly using Ferret ASCII capability.

$t-zero etc are all defined properly. $iset1 is a counter and = 1 $iset2 = 2 and so on.

!!!! dataset 1

define axis/t/from_data/T0="($t_zero)"/calendar=gregorian/units=minutes time($iset1)=(begindate[d=($iset1)]-t0_offset)*24*60+hrs[d=($iset1)]*60

DEFINE VARIABLE/BAD=-9999 plotfield1 = ($plotfield)[d=($iset1),gt=time($iset1)@ASN]

!!!!! dataset 2

define axis/t/from_data/T0="($t_zero)"/calendar=gregorian/units=minutes time($iset2)=(begindate[d=($iset2)]-t0_offset)*24*60+hrs[d=($iset2)]*60

DEFINE VARIABLE/BAD=-9999 plotfield2 = ($plotfield)[d=($iset2),gt=time($iset2)@ASN]

!!!!!! dataset 3

define axis/t/from_data/T0="($t_zero)"/calendar=gregorian/units=minutes time($iset3)=(begindate[d=($iset1)]-t0_offset)*24*60+hrs[d=($iset3)]*60

DEFINE VARIABLE/BAD=-9999 plotfield3 = ($plotfield)[d=($iset3),gt=time($iset3)@ASN]

!!!!     Dataset 4
define axis/t/from_data/T0="($t_zero)"/calendar=gregorian/units=minutes time($iset4)=(begindate[d=($iset4)]-t0_offset)*24*60+hrs[d=($iset4)]*60

!     let plotfield4 = ($plotfield)[d=($iset4),gt=time($iset4)@ASN]
DEFINE VARIABLE/BAD=-9999 plotfield4 = ($plotfield)[d=($iset4),gt=time($iset4)@ASN]


!PLOTTING COMMANDS for the Upper Plot dataset 1 and dataset 3

SET VIEW UPPER

      plot/nolab/vlimits=`YLO_13`:`YHI_13`:`INCR_13`/symbol=40/size=0.2/color=($col1) plotfield1
      plot/ov/nolab/symbol=25/size=0.2/color=($col3) plotfield3

SET VIEW LOWER

       plot/nolab/vlimits=`YLO_24`:`YHI_24`:`INCR_24`/symbol=40/size=0.2/color=($col1) plotfield2
       plot/ov/nolab/symbol=25/size=0.2/color=($col3) plotfield4

Any help/suggestions are greatly appreciated.

Thanks
