Re: Missing data

Hi Vikram,

For individual values, VisAD uses IEEE NaN to represent
missing.  You can set range values in FlatFields to
missing as follows:

  FlatField f = ...
  float[][] values = field.getFloats();
  values[0][j] = Float.NaN;  // this sets a missing value
  field.setSamples(values);

But do not put missing values (i.e., NaNs) into sample
locations of Sets.

Please let me know if this is not clear.

Cheers,
Bill
