New features
- The boundaries of the background map are automatically set to the boundaries of the dataset and variable associated with the first contour or vector instantiation if no defaults have been loaded for the map, and the user hasn't changed projections or map coordinates and the projection is cylindrical equidistant.
- Previously, if the cursor was over a plot, and the first instantiated overlay was a contour object, the value of the dataset at the point under the cursor was displayed. This has been extended to display the magnitude of a vector under the cursor if the first instantiated overlay is a vector plot.
- A help button is available on the main Freud window; this will automatically start up a Web browser and allow the user to connect to either the online Freud manual or the Freud home page.
- Contours below zero are automatically set to be dotted; the zero contour line (if present) is wider.
- Contour line and area displays are reset when contour values change, as opposed to the old method which kept the previous values.
- User can set any desired window tiling parameters (up to 8x8).
- Changed both frvar command and frsource command in two ways:
- The name of the variable or source handle no longer has to be passed to the function; if no handle name is passed, a handle is created automatically. This means that the following syntax is now accepted:
frvar shandle name
frsource filename
- as well as the original syntax.
- Both frvar and frsource now return the name of the assigned handle, regardless of which form was used.
- Added new commands:
- Hardcoded: frtile
- Tcl scripts: frmap, frxy, frcontour, frvector, fropen.
- Added new labeling capabilities. Up to 5 labels may be specified for a plot; in addition to the font size, the justification (left, center, right) and location (top, bottom) can be specified.
- Two new projections: north and south polar stereographic sector maps.
