Re: [ferret_users] horizontal line on time series

Its a good suggestion from Afwande.

but we can get the line at any point in this way also

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

plot/ov/nolab (eoftime*0) + n

`n` is the number where you want to plot the line. suppose n=1 then the horizontal line will be at 1. or n=0.5 line line will be at 0.5 or n= -2 line will be at -2

cheers

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

let xpts = {1000,1950}
let ypts = {0,0}

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
