[ferret_users] contours, hlimits=, x=, ?
Hi Ferret users and developers,
I reported a similar problem a while ago, but now things
are looking "curiouser and curiouser". Basically, I'm wondering
what happens and what should happen when hlimits= (vlimits=) is
specified for a contour plot.
Here's little experiment I've done:
http://iprc.soest.hawaii.edu/~furue/ferret-contours/index.html
First, when I don't specify x= or y=,
yes? set data etopo120
yes? fill/lev=(-6000,4000,1000,-1)/hlimits=10:30/vlimits=80s:60s \
rose
I get a huge white region, as seen in the plot in my webpage cited
above. Is this just me? or does this happen to other users?
Next, when I specify both hlimits (vlimits) and x= (y=),
yes? fill/. . ./hlimits=10:30/vlimits=80s:60s \
/x=10:30/y=80s:60s rose
I get a clean plot.
The plot isn't quite satisfactory, though, because there is a white
region along the edges (and I think I know why).
Since we have datapoints outside our plotting region,
why not use them?
yes? fill/. . ./hlimits=10:30/vlimits=80s:60s \
/x=9:31/y=81s:59s rose
But, this plan partially fails. When we extend only in the y-direction
(y=81s:59s), the contouring region is extended to the northern
and southern edges. Good. But, when we extend in the
x-direction (x=9:31), we get a weired plot, as shown in my webpage.
Maybe am I doing something which shouldn't work?
Regards,
Ryo
