Themes and Templates

Origin_Theme

Origin provides two key features of Templates and Themes that help significantly in performing repetitive tasks such as creating custom graphs and performing repeat routine analysis.

A Theme is a collection of settings that can be saved to a file and used repeatedly. The Theme feature extends across multiple Origin objects such a graphs and worksheets. Themes are also supported in most Origin dialogs, particularly in the area of analysis and data processing. For example, custom settings of a graph can be saved as a Graph Theme and later applied to similar graphs to quickly change graph settings such as preparing a graph for publication. In the context of dialogs, settings in a dialog can be saved as a theme and recalled later from the dialog or even from Origin menus. For example, the Linear Fit dialog can be customized such as to fix the intercept to zero, and the settings can be saved to a named theme and later recalled for analyzing similar data. Origin provides a Theme Organizer tool which can be used to manage graph, worksheet and dialog themes.

A Template is an object that can be saved to file and used repeatedly. The template feature applies to Origin objects such as Graphs and Workbooks. In the case of workbooks the concept is further extended to Analysis Templates. Data in a workbook can be analyzed with any tool such as curve fitting, and the analysis operation settings along with custom report sheets and embedded graphs can all be saved as part of the workbook to an Analysis Template object on file. Such analysis templates can then be used to perform repetitive analysis of similar data using Origin's Batch Processing tool. 

Programming in Origin

Origin is designed to meet the graphing and analysis needs of scientists and engineers in diverse areas of academics and industry. To accomplish this, Origin provides a broad range of tools for importing, analysing, graphing, presenting, and exporting data. As you gain familiarity with Origin, you may want to customise Origin to meet your specific graphing and analysis needs. To facilitate your customisation, Origin includes two complimentary programming languages: Origin C and LabTalk.

Origin C

Origin C is a powerful programming language that supports ANSI C plus some C++ features, including support for string, complex, vector and matrix data types, as well as internal Origin objects like worksheets and graphs.

Origin C is ideal for creating data processing and analysis routines, as well as for developing complicated algorithms.

Programs written in Origin C are compiled and linked to internal Origin objects that are executed during run time. Although not as fast as machine executable code produced by true compilers, a significant improvement in speed can be seen over previous programming options in Origin. In fact, certain tasks, such as computational loops and curve fitting with user-defined fitting functions, execute as much 20 times faster than if they were executed using LabTalk, Origin's built-in scripting language.

For the ultimate in speed, Origin C can be linked to (i.e. it can call exported functions from) external dynamic link libraries (DLLs) that have been built using third party native compilers, such as Microsoft Visual C++. Origin C's link with the DLL enables the passing of pointers from Origin's data structures directly to external DLLs, with little overhead or unnecessary copying of data as would normally be the case when programming in Microsoft Visual Basic.

Code Builder, Origin C's integrated development environment, provides users with a familiar programming language interface that includes color-coded editing and modern debugging capabilities.

Common customisations that can be achieved using Origin C include:

  • Added Functionality: Create new importing, analysis, graphing, and exporting routines.

  • Automation/Batch Processes: Create a routine that automatically performs the tasks you do in Origin.

  • Simulations: Perform simulations with live feedback in Origin. For instance, you might want to execute a Monte Carlo Simulation that dynamically updates a graph.

  • User-defined Fitting Functions: Create complex user-defined curve fitting functions using Origin’s Advanced Fitting Tool's direct link to Code Builder. This allows you to create and debug fitting functions quickly and easily.

LabTalk

LabTalk is a high-level, full-featured programming language which has access to most of Origin's operation. Its syntax and structure are similar, but not identical to C. LabTalk incorporates DOS-style commands with option switches and arguments, as well as object properties and methods comparable to those in Visual Basic.

LabTalk is ideal for performing simple tasks in Origin, as well as for writing and executing quick scripts. You can even create custom LabTalk utilities that run by clicking on a toolbar button.

Origin C and LabTalk

In addition to the power of Origin C and the simplicity of LabTalk, the two programming languages are tightly connected. This connection makes LabTalk commands and variables accessible to Origin C functions. It even allows you to call Origin C functions from your LabTalk code! This makes the ability to create customizations that are callable from toolbar buttons very useful. Origin's built-in cross communication between its two programming languages gives you the best of both worlds and makes it a robust and powerful programming platform for graphing and data analysis.

NAG Software Partner

Origin includes essential elements of the numerical computational routines from Numerical Algorithms Group, Inc. (NAG). Over 300 built-in NAG routines have been selected from the NAG C Library. These routines offer a large selection of time-tested numerical algorithms, such as Statistics, Fourier Transforms, Linear Algebra, Regression, Multivariate Analysis including Principal Component Analysis, and more.

All NAG function calls are accessible from Origin C to allow you to develop applications that require advanced numerical computation.

Other Resources

To learn more about how you can programmatically customise Origin, browse the pages offered in the Programming area by clicking on the desired link in the page. Or, review the Origin sample projects and associated programming source files that are installed in your Origin\Samples\Programming\ subfolders.

To see how other users have programmatically customised Origin, browse the OriginLab File Exchange.

More Features

  1. Batch Processing of Multiple Files or Datasets with Summary Report
    The Batch Processing tool extends the power of Analysis Templates by allowing users to process multiple files or datasets. Users need only to process one file to create an Analysis Template with custom import settings, desired analysis results, and a worksheet that specifies which analysis result parameters to select for reporting. The tool then allows a user to select multiple disk files, or multiple datasets in the project, and performs batch analysis on them. In the end, a report sheet that consolidates the user-specified analysis results is generated from each file or dataset. Multiple files or datsets can also be repeatedly imported into an existing workbook window containing custom analysis settings and a Summary Report sheet.

  2. Batch Peak Analysis (PRO)
    This feature allows OriginPro users to perfom peak fitting of one dataset, save their custom settings as a Theme file, and then perform batch peak analysis of multiple selected datasets in the project using the custom theme. A summary report sheet will be created that lists the dataset name and results from the peak analysis such as peak integration results, or multiple peak properties, depending on the Peak Analyzer goal saved in the theme.

  3. Slide Show of Graphs and Favorites Folder in Project Explorer with Support for Shorcuts
    You can now view all graphs in your project, or in a particular subfolder, in a full-screen slide show. The slide show can be customized to play in a loop or end when last graph is displayed. Custom key entries can be used during the slide show including options to turn off speed mode if present, or go to the currently displayed graph window. The order of the slides can be set using a newly introduced slide order column in Project Explorer. This feature combined with the Favorites Folder feature allows for user to easily collect together all desired graphs in a project for viewing or for presenting to colleagues.

    Shortcuts to any Origin Window type such as graph, worksheet, or matrix can be added to any folder in Project Explorer. A Favorites folder has also been introduced, allowing user to right click on any window to quickly add shortcut to Favorites folder. This allows for easy organization of key windows and graphs in your Origin Project, and can then be combined with the Slide Show feature to create custom presentations.

  4. Export Multiple Graphs to PowerPoint
    In addition to viewing graphs as a slide show, you can also export all graphs in the project or in any particular subfolder to a Microsoft PowerPoint file. The order of export can be set using same control used for setting slide show order. Controls are provided for specifying vertical and horizontal offsets and size in units of percentage of page size, for inserting the graph into the PowerPoint slides.

  5. Password Protection of Origin Projects and Audit Log on Project Saving
    Origin Projects can be protected in version 8.1 using a password. User can also turn on an Audit Log which maintains a log of who saved the Project and at what time. The Audit Log can optionally be protected by a separate password, allowing for a manager to turn on the audit log and check the listing to view activity on the project.

    The new features of Password Protection and Audit Log time stamps, combined with Origin's ability to import data from databases using customizable SQL queries saved within the Project, allows for electronic record keeping. These features are important for submitting Origin Projects to Government Agencies that have specific security guidelines such as to the US-FDA which requires 21 CFR Part 11 compliance.

  6. New Graph Types: Ternary Contour, Weibull Probability, Windrose, Multi-Axes Plotting Tool
    To complement the existing array of over 60 supported graph types, the following new ones are being introduced in Origin 8.1:

    Ternary Contour Plot. This plot utilizes a fourth column of Z values to determine the contours for XYZ ternary data. Customization options include smoothing, and the newly introduced major and minor level contour controls and enhanced support for color palettes.

    Weibull Probability Plot. The Weibull probability plot displays percentiles in order to determine if the data could be from a Weibull distribution. Data that are truly Weibull will plot as a straight line on the graph. Origin plots the reference line automatically, based on the Weibull parameters, which you may specify or let Origin estimate from the data.

    Windrose Plot. The Windrose plot combines elements of a 2D polar graph with a bar chart, and is very useful for displaying directional data. It is most often used to display variations in wind speed and direction.

    New Templates.
    New graph templates have been added to easily plot multiple datasets in same graph with shared X axis and multiple color-coded Y axes with offsets.

  7. Data Reduction Tools, and Data Rearrangement Tools, Including Pivot Table
    Data consisting of multiple mixed groups can now be unstacked to separate sets of columns by using one or more columns as group variables. Once grouped data is unstacked, graphing and analysis can be performed with more flexibility.

    Multiple new tools have been introduced for data reduction. These include a tool for deleting rows by skipping, such as deleting every alternate row, and a tool for reducing data with duplicate X values.The duplicate reduction tool allows for specifying what quantity to use for replacing Y values, such as mean, min, median or sum.

    OriginPro provides additional tools for data reduction. These include a tool to reduce data to evenly spaced X values, and a tool to reduce data based on subgroup statistics of X values. Both tools provide multiple methods for deciding how to distribute the reduced data. The tools also provide a preview window of the results.

  8. Signal Decimation, Rise and Fall Time Analysis, Signal Envelopes (PRO)
    This tool provides you with the ability to reduce data by a specified factor, with an optional filter specification. The filter options include moving average or finite impulse response.

    This tool can be utilized to measure rise and fall time of signals. An interactive panel can be used to specify the range of interest on the graph.

    This tool computes envelope of a signal. Options are provided for computing either upper or lower envelope, or both. A smoothing option is also provided allowing user to specify number of points to be used for smoothing.

  9. X Error Bars Support for Linear Regression (PRO)
    Support for performing linear regression taking into consideration X error data is being introduced with this tool in OriginPro. The tool supports both X and Y error bars.

     

  10. Custom Menu Configuration and Support for User-Defined LabTalk Script Functions
    The Custom Menu Organizer tool can be used to customize existing menu items by turning selected items off, or to add your own additional main menu items for tailoring the software to meet the specific needs of your end user. Multiple menu configuration files can be created and saved, and shared with other users. Sharing such menu configuration files is supported with the group folder. This feature can be utilized in organizations to provide a custom, consistent interface for all users, or to customize the interface for including the software with instrumentation.

    Support for user-defined functions with multiple parameters has been added to Origin's LabTalk scripting language . Functions can be easily defined and used in script such as from the function plotting interface.

Features

Origin's NLFit tool provides an intuitive interface for fitting your XYZ or matrix data to a surface model.

  • Fit XYZ or matrix data from a worksheet or graph.

  • Locate multiple peaks in your surface data using one of many peak identification methods.

  • Fit multiple peaks using automatic peak parameter value initialization.

  • Fitter uses the Levenberg-Marquardt iterative algorithm.

Peak Fitting Module

Origin's Multiple Peaks Fit tool can perform non-linear fitting to multiple peaks. OriginPro provides two additional tools with extended peak-fitting capabilities - the Quick Peaks gadget and Peak Analyzer.

Fitting Peaks with Built-in or User-defined Functions
Fit multiple peaks within a dataset using one of our many built-in fitting functions, or create your own. Origin provides over 25 built-in peak functions:

Fitting With Different functions
Peaks in a spectrum may sometimes need to be described by different functions. For instance, in the data displayed below, the first peak is best described by a Lorentzian function while the second is best described by a Gaussian function. Using the Peak Analyzer tool, you can easily assign a different function to each peak, and then perform fitting on all peaks simultaneously.

Fitting Baseline
The Peak Analyzer tool can fit baseline along with peak data. This can help avoid errors that might be introduced by subtracting the baseline in the fitting process.

Controlling Fit Parameters
Like the Nonlinear Curve Fitter (NLFit) tool, the Peak Analyzer tool offers full control over the fitting process. With the Peak Analyzer tool, you can:

  • Fix peak parameters or specify upper and/or bounds

  • Share parameters between functions

  • Easily apply bounds and share settings across multiple parameters

  • Specify linear constraints on fitting parameters

Reporting Results

When the fitting process is complete, Origin generates a report graph that includes raw data, individual peaks, and the cumulative fitted curve. Origin also creates a tabulated report sheet with fitting statistics results such as Degree of Freedom, Adjusted R-Square, and reduced Chi-Sqr values. In addition, detailed characteristics of all peaks are summarized in a separate worksheet.
