Re: Newbie Question

Hi KathyLee,
Great progress.
The default color map for a ScalarMap to Display.RGB is a grey
scale.  But if you construct a new LabeledRGBWidget(ScalarMap),
then you will get a color spectrum (you can also explicitly set
the color map in the ColorControl returned by
ScalarMap.getControl()).  Note that mapping to IsoContour will
produce contour lines rather than a color image.
For your NullPointerException, would you please run under jdb
and then send me the NullPointerException message including the
stack trace with line numbers.
Your grey-scale image should be continuous.  The fact that it
is many dots (i.e., 'point mode') indicates that the data
may contain missing data.  I'll take a look, so please send
your data file to our anonymous ftp:
  login: anonymous
  password: simunich@xxxxxxxxxxx
  ftp> bin
  ftp> cd pub/incoming
  ftp> put data_file_name
  ftp> put
  ftp> quit
then send me an email telling me the name of the data file.  Also
please send me the latest version of  Thanks.
