[gradsusr] cannot change yinterval of hovmoller plot

[Lyndz]

Dear GrADS experts,


I am trying to modify the interval of the y-axis in the attached
time-longitude plot.

[1] I tried to change the 'set ylint' line in my script but *the label
interval does not change*. The current interval remains at 5 even if I
change the ylint to say, 10.

[2] Is there a way to increase the number of tick marks on the y-axis?


I'll appreciate any suggestion on how to do this correctly.


Here's the script:

'sdfopen bpass_aug9_sep7_30-60filt_1994-2008.nc'
'set display color white'
'c'
'set mpdset hires'
'set grid on'
'set grads off'
'set parea 1.5 8 2 10.5'
'set font 1'
'set xlopts 1 5 0.2'
'set xlint 10'

*'set ylint 10'*

'set ylopts 1 5 0.2'
'set lon 100 180'
'set gxout shaded'
'set tlsupp year'

'set t 1 84'
'define var=ave(xbpf,lat=10,lat=20)'
'color -10 10 1 -kind
mediumblue->royalblue->cornflowerblue->white->khaki->orange->red'
'set y 1'
'd var'
'xcbar 1.5 8 1 1.25 -line on -fs 2 -fh 0.18 -fw 0.18'

**********************************************************
*Overlay contours

'set gxout contour'
'set ccolor 1'
'set cint 1'
'set clab forced'
'd var'
*'set line 4 1 1'
*'draw line 1 10 5 5'

'quit'


Here's the detail of the file:

netcdf bpass_aug9_sep7_30-60filt_1994-2008 {
dimensions:
lon = 144 ;
lat = 73 ;
time = UNLIMITED ; // (92 currently)
variables:
float lon(lon) ;
lon:standard_name = "longitude" ;

lat:standard_name = "latitude" ;
lat:long_name = "latitude" ;

time:long_name = "Time" ;
time:units = "hours since 1800-1-1 00:00:00" ;
