Hi all,
Golla and I talked outside the list a bit. The grid of the data is
24 points in Z and 51300 in the T direction. Ferret's contouring
algorithm just doesn't work on such a grid.
And in fact there are not enough pixels in the plot page to show
anything near 51000 points. A plot of a subset of the data in the T
direction should work fine, for instance,
fill/L=1:5000 temp
To plot the data for the whole time range, the right answer here is
to regrid to a coarser grid in time, or even just decimate the data
for plotting.

Hi Golla,
To follow up, an easy way to make the check that Steve is
suggesting is to do a SHADE plot with exactly the same qualifiers
and region as your FILL command. That should show whether this is
the issue.

Hi Golla,
Check and see if there are lots of missing values in your data.
The FILL command requires adjacent valid points in order to
trace the boundaries of the color changes, so it is not suitable
when there are lots of embedded missing values.
If you regrid using an @ave regridding transformation, then the
coarser grid will have valid data as long as there is at least
one valid point from the fine grid within the coarse grid cell.
So the number of missing values is greatly reduced.

Hi all,
Now-a-days I am facing some problem with the high
resolution time series data (5 second).
Suppose I am having data in z axis and t axis (5 sec) for
suppose 5 days. When I try to plot the depth-time section
using fill command, it is not plotting anything (blank
plot) but scale bar will be there.The same data when I
plotted with shade command, only second half of the data
is plotted. Then, I checked whether data is there inside
the .nc file or not. Suprising data is there inside. If I
regrid this data to a coarser resolution in t-axis, again
full data is plotting both either with shade and fill
commands. I think this a bug or ferret is not able plot
high resolution datasets. I didnt understand this weird
behaviour. Any help in this regard is appreciated.
Thanks in advance.
