OriginLab has released OriginPro 9.1 which features auto-positioning of labels in graphs, with the ability to add leader lines and to place labels arbitrarily such as attaching to data plot, to axes, or at fixed positions within the graph layer.
The software provides Grouped Box Chart and Column/Bar Plot, Piper Diagram, 3D Ternary Surface Plot, 3D Waterfall Plot, 100% Stacked Column/Bar Plot, and Marginal Histogram/Box Chart graph types. Data analysis features include Akima Spline interpolation and Lowess and Loess smoothing. Time-saving features include Batch Plotting to create duplicate graphs from other worksheets and columns, Batch Analysis on multiple data plots using interactive gadgets, copying and pasting analysis operations to new data, and a custom worksheet header row for quickly assigning and editing column formulas.
OriginPro contains all Origin 9.1 features, as well as tools for Partial Least Square Regression, additional Power and Sample Size tests, an Orthogonal Distance Regression algorithm for Nonlinear Curve Fitting, a tool to fit and rank multiple fitting models, and a gadget to perform 2-D integration over a region of interest.
