Todd,
I remember at some point that that options wasn't working but it is
working in our pre-release code at the moment.
I'd encourage you to hold on a short while and wait for the next LAS
release.

Jon,
I appreciate the clarification. Clearly I was misreading what the setRange()
method was doing.
However, your suggestion takes me back to where I began. From my original
post: "When making SST maps (xy), I discovered I can fix the range and
stepsize of the contours by using specifying the fill_levels. Is there an
analogous method for specifying the vertical axis on a plot of SST vs.
longitude (x)?"
Yesterday Ansley had suggested I could use the "Dependent Axis Scale" setting
in the forthcoming LAS release. I noticed that the standard UI on my
Armstrong 0.4 installation includes a form field for setting the Dependent
Axis Scale on longitude line plots. I played with this, but it did not seem
to have an effect on the plots I generated. Is it the case that this option
is displayed on the UI, but is not supported in the 0.4 version of the
product server.
Thanks as always.
Regards,
Todd

Todd,
The Req.setRange() method sets the range of the *axis *in the particular
request. It doesn't set the range of *values *you're looking for. What
you're doing is telling LAS to look for SST values where the Z axis
(depth) has a value between 15 and 33. Not what you want!
The easiest way to have Ferret only display values between 15 and 30 is
to specify the ferret property 'fill_levels' like this:
Req.setProperty('ferret','fill_levels','(15,33,1)');
Hope that helps.

Roland,
I actually tried setting the range as part of the request, but I get
an "illegal limits" error, even though the range I set contains valid SST
values. Perhaps I have another problem. Should I be looking at how the
axes are set for my dataset, or is there a problem with my syntax?
Here's what I added to my _javascript_ request:
Req.setRange('z','15.0','33.0'); // Plot SST on axis with range 15-33
degrees C
Here's what I get in return:
: illegal limits: PHSSTA is not in the range Z=15:33 Axis extremes are
Z=-0.5:0.5;, ERROR RUNNING SCRIPT statement executed
**ERROR: illegal limits: PHSSTA is not in the range Z=15:33
Axis extremes are Z=-0.5:0.5
PLOT /NOKEY/SET/TITLE="Sea Surface Temperature mixed night and day:
monthly (degrees Celsius)"
PHssta[d=1,X=135:285,Y=0:0,Z=15.0:33.0,T="15-Dec-1997":"15-Dec-1997"]
Command file, command group, or REPEAT execution aborted
STOP -script mode, ERROR RUNNING SCRIPT statement executed
It doesn't make sense to me that LAS expects the SST values to fall
between -0.5 and 0.5 since I can routinely generate plots of values well
outside that range.
Thanks in advance.

Todd,
If you're using the LAS request _javascript_ obect to send the request
then you can always set the plot range in the request to the region of
interest. What Ansley suggested is the way to do it in a Ferret script,
but I think you really want to just set it in the request.

Hi,
I'm trying to force my LAS-generated plots to always use the same axes
and range. I'm developing an educational activity in which middle
school students will compare SST data at different times. I want to fix
the axes so that it will be easier for students to read and determine
how the data are really changing -- not just how the axes are changing.
When making SST maps (xy), I discovered I can fix the range and
stepsize of the contours by using specifying the fill_levels. Is there
an analogous method for specifying the vertical axis on a plot of SST
vs. longitude (x)?
Thanks,
Todd
