  • Library: Unidata's netCDF-Java updated to v. 2.2.16.
  • Min-max note extended from PlotNote.
  • Bugfix: NaN values were not placed in edge areas if second input array in combination plot had bounds which did not fill output grid (e.g., a lon-lat dataset which does not extend to the poles).
  • Shifted certain data access activities (i.e., creation of variable object, altering chosen slice from that variable, etc.) out of event thread in order to reduce blockage of GUI event handling.
  • Created TaskQueue to manage sequential requests to change data being plotted.
  • Display non-modal progress "windoid" when creating new plots and when changing data already plotted.
  • Added Raisz Half Ellipsoidal projection to lon-lat plots.
  • Library: iText Java-PDF updated to v. 1.4.3.
