LabPlot’s worksheet comes with new visualizations and more advanced plots, including:

• Bar plots

• Plot templates that allow you to save and re-use custom plot configurations

• Error bars in histograms

• Rug plots for box plots and histograms

• More flexible and customizable box plots

• Reference ranges, that is, custom areas on the plot to highlight x- and y-ranges

• LaTeX error messages in text labels when rendering with LaTeX

Spreadsheet

The Spreadsheets gain more functions and operations to modify and generate data:

• Data sampling (random and periodic methods)

• Data flattening to convert pivoted data to column base format

• Baseline subtraction using the arPLS algorithm

• Heat-map formatting for categorical data in text columns

• Column statistics for text columns, including the frequency table, bar and Pareto plots

• Functions to access arbitrary cells of columns with cell (f(index), g(column, ..))

• Functions to work with column statistics (size, mean, stddev, etc.)

• Ability to specify the seed number when generating random numbers

Analysis

The new analysis tools added to LabPlot 2.10 include:

• Maximum likelihood estimation for several distributions

• Guess start values of fit parameter for polynomial models by linear regression

• Export the results of a computation to a new spreadsheet

• Fourier filtering for DateTime data

Import/Export

LabPlot 2.10 adds support for new file formats and multiple optimizations to improve import performance:

• Import of Excel .xlsx files

• HDF5: support VLEN data import

• Reduced memory consumption when importing from a database table into a spreadsheet

• Reduced memory consumption during the spreadsheet export to SQLite databases

• Faster import of files with a large number of columns

Notebook

The 2.10 release Improves the variable panel and plot export:

• Show the type of a variable, its size (in Bytes), and its dimension (number of rows and columns) for backends that provide this information

• Properly show the values of Octave’s row vectors and matrices

• Allow to copy variable names and values to the clipboard

• Export plot results to vector graphic formats (PDF and SVG)
