Changelog before SciDAVis 1.D1

=== Release 0.2.4, 2010-03-12 === Most important changes (since 0.2.3) - Some parts of the Python API have been marked as deprecated and generate warnings when used. This may be a bit unusual for a bugfix release; on the other hand, they won’t be removed any time soon and inserting the deprecation warnings now will give everyone as much time as possible for getting accustomed to the API we’re moving towards. Most prominently, Table.cell(column,row) and Table.setCell(column,row,value) are deprecated in favour of Table.column(column - 1).valueAt(row - 1) and Table.column(column - 1).setValueAt(row - 1, value) (note that the column/row INDICES DIFFER BY ONE!); the same goes for Table.text(c,r) -> Table.column(c - 1).textAt(r - 1) and Table.setText(c,r,text) -> Table.column(c - 1).setTextAt(r - 1,text). This serves multiple purposes. It simplifies the interfaces by grouping all functionality specific to a certain column in the Column class; it allows column objects to be stored and passed around; and it moves from the unconventional 1-based indexing to the more conventional 0-based indexing. Future additions to the API will increasingly make use of the columns-as-objects paradigm. - lots of bugfixes, again including crashes - fixed compatibility issues with Qt 4.6 and SIP 4.9 - performance improvements - substantially improved support for plots involving date/time data - added two Czech translations: a default one by Pavel Fric (feedback requested via http://fripohled.blogspot.com) and an alternative one by Jan Helebrant - updated Spanish translation, thanks to Mauricio Troviano; Brazilian Portuguese translation, thanks to Fellyp do Nascimento; and German translation - fixed and extended many parts of the API for Python scripts, including the new methods Layer.pickPoint() MDIWindow.clone() Folder.save(filename) newGraph(string) Layer.printDialog() Graph.printDialog() Layer.setRightTitle(string) Layer.setTopTitle(string) Layer.grid() # => returns an instance of the new class Grid Layer.insertFunctionCurve(formula,from=0,to=1,points=100,title="") Layer.insertPolarCurve(radial_formula,angular_formula,from=0,to=2*pi,parameter=“t”,points=100,title="“) Layer.insertParametricCurve(x_formal,y_formula,from=0,to=1,parameter=”t“,points=100,title=”") Matrix.recalculate() the constants QwtPlot.yLeft, QwtPlot.yRight, QwtPlot.xBottom, QwtPlot.xTop for specifying axes and the Grid class - multiple graphs can have active tools simultaneously - based on user feedback, the default behaviour when importing ASCII files has been changed to interpret the data as numeric (only applies to fresh installations of SciDAVis) - automatic resizing of table rows for multi-line cells intentionally dropped, because this seems to be rarely needed and has a huge impact on performance for large tables

=== Release 0.2.3, 2009-07-05 === Most important changes (since 0.2.2) - fixed many more bugs, including various crashes - performance improvements - improved pasting of cells from OpenOffice.org Calc and KSpread into tables - Brazilian Portuguese and German translations improved - Some build system fixes for building on MacOS X Tiger and detecting lupdate-qt4/lupdate - now also compatible with Qwt 5.2.0 - main window remembers size from the last session instead of always displaying maximized - added the following methods to the Python interface: MDIWindow.name() MDIWindow.setName(string) Note.text() Note.setText(string) Note.executeAll() Note.setAutoexec(bool) Note.exportASCII(filename) Note.importASCII(filename)

=== Release 0.2.2, 2009-04-19 === Most important changes (since 0.2.1) - added Brazilian Portuguese translation by Fellype do Nascimento - fixed opening of legacy files with non-numeric data - fixed various crashes - fixed importing of numeric data as new rows or overwriting the current table - fixed various issues with invalid/empty cells - implemented a more sophisticated file-saving protocol, which is supposed to protect against data loss in the event of a system crash shortly after saving the file; see http://bugs.launchpad.net/ubuntu/+source/linux/+bug/317781/comments/54 - performance improvements - Python function Table.importASCII() reimplemented, which was missing in SciDAVis 0.2.0 and 0.2.1.

=== Release 0.2.1, 2009-03-09 === Most important changes (since 0.2.0) - fixed saving of project files with function/fit curves - fixed opening of backup copy on discovery of a corrupt project file - Spanish translation update by Mauricio Troviano - fixed several regressions introduced by the table/matrix rewrites in 0.2.0 - added per mille and per ten thousand signs to SymbolDialog - compatibility problems between SIP versions triggers a warning instead of a crash (happens sometimes when SIP version at runtime differs from the one used at compile time)

=== Release 0.2.0, 2009-02-14 === Most important changes (since 0.1.4) - multi-level undo/redo for all operations on tables and matrices - many operations on tables and matrices now support non-contiguous selections - the important options/controls for matrices and tables are now integrated in a sidebar of control tabs which make working with column or matrix based data much more convenient (almost no more opening and closing of dialogs necessary) - tables now support different formulas for each cell - numeric values are now stored independent of their textual representation, i.e., you don’t lose data when hiding decimal digits - formula edit mode: tables feature a new mode which allows the user to individually edit the formula for each cell - invalid cells: tables now mark cells without input as invalid rather than treating them as 0; these cells are ignored in plots - date/time values are now internally stored as QDateTime objects which opens up many new possibilities of date/time manipulation using PyQt/Python scripting - many bug fixes

=== Release 0.1.4, 2009-02-08 === Most important changes (since 0.1.3)

=== Release 0.2.0-beta1, 2008-08-10 === Most important changes (since 0.1.3) - multi-level undo/redo for all operations on tables and matrices - many operations on tables and matrices now support non-contiguous selections - the important options/controls for matrices and tables are now integrated in a sidebar of control tabs which make working with column or matrix based data much more convenient (almost no more opening and closing of dialogs necessary) - tables now support different formulas for each cell - numeric values are now stored independent of their textual representation, i.e., you don’t lose data when hiding decimal digits - date/time values are now internally stored as QDateTime objects which opens up many new possibilities of date/time manipulation using PyQt/Python scripting

Known issues (to be fixed until 0.2.0 stable): - the Python bindings for the new table features are not finished yet - there is currently no way to display which formula has been assigned to which cell in a table - the date/time column functionality has not been completely integrated and may lead to empty plots in many cases

=== Release 0.1.3, 2008-04-19 === Most important changes (since 0.1.2) - page orientation for PDF/EPS export can now be chosen manually - executing script code now gives a visual feedback - new Windows installer - many improvements to make compilation and Linux packaging easier - fixed graph duplication - fixed unnecessary graph rescaling - several other bugs fixed

=== Release 0.1.2, 2008-02-03 === Most important changes (since 0.1.1) - fixed crash when changing the type of a curve - fixed crash when plotting an empty table - fixed the fit wizard which did not accept function definition - fixed pasting into tables - fixed some other minor issues

=== Release 0.1.1, 2007-12-21 === Most important changes (since 0.1.0) - several bugs fixed

=== Release 0.1.0, 2007-08-05 === Most important changes (since QtiPlot 0.9-rc2): - improved handling of custom decimal separators - many improvements/additions to Python scripting - improved user interface: restructured menus and tool bars, several restructured dialogs - script window removed since notes offer the same capabilities - more stable project loading/saving - easier ASCII import/export, improved appending of projects and Origin graphs - lots of small improvements and bug fixes - export to eps and pdf without large white borders
