Re: [ferret_users] horizontal line on time series

[afwande juliet <afwandej965@xxxxxxxxx>]

Try this command and try playing with numbers to get it where you want it

plot/nolab/color=blue/thick/I=1/TITLE="time function 1"/VLIMITS=-4.0:4.0:0.5 eoftime
let xpts = {1000,1950}
let ypts = {0,0}
plot/vs/over/line/color=black/nolab xpts,ypts

Hi Ferreters

I would like to overlay a horizontal line on a time series at y=0  (see timeseries.png) however, this is being more difficult than I could have ever imagined.

Below is my script that generates a time series.

USE JFM_NCEP.nc

USE JFM_20th.nc

USE JFM_ERAINT.nc

!  Compute and save the spatial EOF functions.  These have the same units

!  as the data.

LET eoftime = EOFSVD_TFUNC(hgt[X=10E:43E,Y=0:33S,k=12,d=1])*-1

LET eoftime2 = EOFSVD_TFUNC(hgt[X=10E:43E,Y=0:33S,k=14,d=2])*-1

LET eoftime3 = EOFSVD_TFUNC(hgt[X=10E:43E,Y=0:33S,d=3])*-1

!go multi_view   [rows],[columns],[xsize],[xstart],[xgap],[ysize],[ystart],[ygap],[PRefix] 

   go multi_view   3,      1,       0.5,   0.1,   0.15,   0.25,   0.1,    0.07  

 SET WINDOW/ASPECT = .5

set view V11

      PPL SHASET RESET

      plot/nolab/color=blue/thick/I=1/TITLE="time function 1"/VLIMITS=-4.0:4.0:0.5 eoftime
