Origin is a computer program for scientific graphing and data analysis

Origin is an easy-to-use data analysis and graphing software used by over 100,000 scientists and engineers worldwide.
Origin is a proprietary computer program for interactive scientific graphing and data analysis. It is produced by OriginLab Corporation, and runs on Microsoft Windows. It has inspired several platform-independent open-source clones like QtiPlot or SciDAVis.
Graphing support in Origin includes various 2D/3D plot types.
Data analyses in Origin include statistics, signal processing, curve fitting and peak analysis. Origin's curve fitting is performed by the nonlinear least squares fitter which is based on the Levenberg–Marquardt algorithm.
Origin imports data files in various formats such as ASCII text, Excel, NI TDM, DIADem, NetCDF, SPC, etc. It also exports the graph to various image file formats such as JPEG, GIF, EPS, TIFF, etc. There is also a built-in query tool for accessing database data via ADO.
Peak Fitting
The Peak Analyzer tool in OriginPro provides the additional capability of finding and fitting multiple peaks in your spectra. Baseline anchor points can be customized and fit with a suitable fitting function, and the baseline fitting can be included as part of the final peak fitting process. A detailed Fit Control dialog is provided to control all aspects of peak fitting including mixed peak functions, peak centers and widths, sharing parameters, and imposing bounds and linear constraints on parameters. Graphical as well as tabular results are generated as part of the final fit report.
Surface Fitting
OriginPro can fit a 3D surface to XYZ data points. The surface and data points can be displayed together, including droplines from the points to the surface.
OriginPro expands on the statistical analysis capabilities of Origin by providing additional tools in Descriptive Statistics, Discrete Frequency counting, normality tests, correlation analysis, one-way and two-way Repeated Measures ANOVA, many nonparametric tests such as Friedman ANOVA and Two-Sample Kolmogorov-Smirnov Test and Mann-Whitney Test, Survival Analysis tools including Weibull Fit and Cox Proprotional Hazard Model, ROC Curves, and Power and Sample Size tests.
Signal Processing
Advanced signal processing features in OriginPro include Short-Time FFT (STFT), Hilbert Transform, Coherence, 2D FFT and 2D FFT-based Filtering, 2D Correlation, and Wavelet analysis.
Image Handling
OriginPro offers more ways to handle your image data, including alpha blending, pixel logic, morphological filtering, and interpolated background subtraction.
Analytical Power
With so much analytical power, OriginPro is the software of choice for those who want a single data analysis and graphing solution.
