2009/06/22 - QtiPlot 0.9.7.8 released. Special thanks to Olivier Dubreuil for his bug reports and suggestions.
Changes:
- Slightly modified the Qwt 5.2 library in order to allow painting of 2D curves using floating point coordinates,
resulting in a more accurate/smoother represantation of the data (the modified source code of this library is shipped
with the QtiPlot archive in the "3rdparty/qwt" folder).
- Implemented waterfall plots.
- Added a powerfull exploration tool for 2D plots combining panning and continuous zooming.
- Improved the export of 2D plots to the EMF format on Windows. Now when you copy a plot window or a layer, the images are stored to the clipboard as metafiles using EmfEngine.
- Improved contour line plots. Now the user has the possibility to:
- use the formula defined for the data source matrix in order to calculate Z values, resulting in smoother contour lines
- display text labels for the Z contour levels
- define custom Z levels
- define custom colors and pen widths for each Z level
- Improved Python scripting for 2D curves. Added scripting support for:
- image/contour line plots (spectrograms)
- histograms
- waterfall plots
- Fixed crash when calling newNote() in a Python script with Python 2.6 (thanks to Knut Franke).
- Improved color handling for curves/symbols in a 2D plot:
- the user can define custom colors.
- it is straightforward to restrict all colors to a gray scale or to
define indexed colors via the "Palette" plot layer context menu (Feature Request #00381).
- Improved data fitting capabilities:
- fixed fitting with user defined functions containing removable singularities.
- improved display range of prediction and confidence bands.
- implemented Feature Request #004587: "Fit through zero".
- added planck_wavelength fit plugin, thanks to Knut Franke.
- Improved the display of analytic 2D functions: in case of logarithmic x-scales the values are calculated using equidistant data points on the log scale.
- Improved 2D plot layers context menu.
- Fixed file saving for filenames containing dot signes.
- Added Chinese translation thanks to Fox (Chen Zhang).
