GraceGTK change log

Gracegtk-0.2.0 "layers"

• The layers feature is now implemented.
• The spectrum 2 example had been revisited to show how it works.

gracegtk-0.3.0 "contours"

GraceGTK can now draw 2D colored maps (XYCMAP type) when the values are scattered on a regular rectangular grid. Inspired by the fxcoudert patch, I have added the plotting of level curves (contours). Only ps ,eps and pdf drivers can print the colored surface and no smoothing is done. Arrays with two indexes and specific commands had been added to the *.agr language. See the documentation and file pars.yacc.

The old Grace-5.1.22 "Plot" menu does not follows the new features, thus it is deactivated by default. An entry in the Menubar/Wiew menu allows to reactivate these menus at your own risk.

gracegtk-0.3.1 is a maintenance release to correct the following bugs:

• The callback ge_tree_CB() made crashes when called by cascading callbacks with event=NULL; the event switch is now protected and default to mouse Button1 in that case.
• The use of leavegraphics() in zc_contours made output drivers crashes except for the GTK driver.
  The coding of column selection when importing ASCII data with this option made the Windows executable crash: the new coding is correcting this but is always a source of potential memory leakage.
• The XYCMAP example file was not copied by "make install".

gracegtk-0.3.2 is a maintenance release.

• The time stamp right pane menu is reestablished.
• The synchronization between project/main menu and printer setup menu is enhanced.
• For XYCMAP, the rectangles are now centered.

**gracegtk-0.3.3 ** add CAIRO drivers for PDF, PNG and SVG output formats.

These drivers allow a correct output of colored maps (xycmap sets) without additional library.

gracegtk-0.3.4

• Added instantaneous update when an element is clicked in the explorer right pane. This feature is now the default and can be disabled/enabled in the Edit/Preferences menu.
• A bug when trying to rescale an object in a compound is corrected

gracegtk-0.4.0 "X-splines" and "Polylines"

• The "Line" type is extended to "Polyline" that can be
  interpolated into a smooth curve.
• New X-spline (borrowed to xfig) interpolation is introduced
  in 3 places:
  • in Data/Transformation/Interpolate to create new sets,
  • in Explorer/Set/Line tab to connect points
  • in Explorer/Polyline to smooth polylines.

Bugs corrections:

• in Data/Transformations/Interpolation splines
  when trying to use the abscissas from another set.
• Added a if to have always the Colorbar of xycmap sets
  oriented upward with increasing values of z.
• Bug introduced by instant_update when changing
  obj (arc,..) attachment to gno and coord. type
• When rescaling object in compound with world loctyp
• Lack of UTF-8 <-> Latin-1 conversion for labels in treeview.
• and others...

gracegtk-0.4.1 "Wavelets"

• Added one dimension wavelet transforms
• Experimental differential "Savs as..." option to avoid
  printing parameters identical to hard coded templates
• And some bugs corrections...

gracegtk-0.4.2 "CUPS"

• Added CUPS support.
• Known standard page sizes are extended to ISO 216
  A0 to A9 and B0 to B9
• Mouse Button3 menus are revisited.
• Bugs corrected: rescaling compounds, rescaling in another graph...

gracegtk-0.4.3 "Mouse button 3"

• Mouse button 3 in TreeView allows to create/break/prune directly compounds
• Mouse button 3 in some right pane menu entries fires the Font tool popup.
• Menubar/Plot entries now open TreeView instead of old grace-5 menus
• The "special" tab in the Explorer/Set pane has been revised

gracegtk-0.4.4

Mouse button 3 in spin button used to set x1, y1, x2 and y2
in object right pane window fires a menu to set min ,max,
step and value of the entry will be scanned by the command
interpreter.

gracegtk-0.4.5

The precision parameter is now used for axis date format
to give the number of digits displayed as fractional part
of seconds.

gracegtk-0.5.0 "LOESS non linear fit"

• Added 1D LOESS curve fitting (need BLAS library)
• Tried to enhance Fortran compiler detection
  using AC_FC_WRAPPERS autoconf macro

• Added two utility commands:

  OPEN RESULTS FILE sexpr

  CLOSE RESULTS FILE

  acting as the -results option of command line
