2025/01/26 - QtiPlot 1.2.5 release available. New features and improvements:
Implemented the possibility to perform a multi-peak fit using mixed peak profiles (Pro edition only).
Improved the Fit Multi-peak dialog: added the possibility to fine-tune the positions of the peaks before performing the fit.
Removed obsolete fit algorithms from fit wizard and dropped support for deprecated plug-in fit method.
Replaced obsolete plug-in fit models (
ExpLin
,
ExpSaturation
,
Rational0
,
PlanckWavelength
) with built-in counterparts.
Added
Rational2
and
Reciprocal
built-in fit models.
Added the possibility to customize the default line style for data fit curves.
Implemented the possibility to group box curves based on the comments in their source data table.
Improved frame dialog for 2D plot objects.
Improved the Integrate function dialog: added the possibility to perform integration over infinite intervals.
Implemented a SymPy interface
for performing
symbolic differentiation
and
integration of analytical functions.
Added support for mouse selection of 2D plot spline and Bezier curves.
Added Hide action to the context menu of 2D plot objects.
Implemented a two steps verification procedure for student licenses.
Bug fixes:
Fixed parameters table disappearing from 2D plots after a fit operation performed using the fit wizard.
Fixed positioning data labels for 2D plot layers with log Y axes.
Fixed import from ASCII files of data values containing + sign followed by space characters (e.g. '+ 1.23').
Fixed import of ASCII files having comma characters in their name.
Fixed filling area under 2D plot curves with decreasing abscissas.
Fixed drawing of 2D axis backbones in case of large line widths.
Fixed exporting the frame of 2D plot layers.
Fixed hidden dialog not becoming visible after click on its title in the "Windows | Dialogs" menu list.
Fixed changing the visibility of violin plots.
Fixed adding of ridgeline curves to an exiting 2D plot.
Fixed multipeak fit tool: line dialog became visible after a doubleclick on a line object during peak selection.
Fixed size of 2D plot windows imported from Open Document Spreadsheet files (.ods).
Fixed import of Excel .xls files using LibreOffice.
