2.1.8 Apps


Apps are custom applications for Origin that perform specific graphing and/or analysis tasks. Apps are not pre-installed with Origin. Instead, Origin users can browse for Apps and download and install them from the File Exchange area of the OriginLab website. This mechanism provides users the flexibility to add only those Apps of interest to them, and allows OriginLab to develop and distribute Apps independent of the Origin product release cycle. The Origin user community can also develop and share Apps via File Exchange. For notes on how to create an App, refer to the Create and Update Apps for Origin tutorial.

The Apps Gallery

Apps that are installed by the user are visible in the Apps Gallery window of the Origin interface. By default, the Apps Gallery is docked on the right side. If the window is not visible, you can use the menu View: Apps to turn it on.

The top-most icon in the galley window is the Add Apps icon, which will bring up the App Center dialog. With this dialog, you can view and search Apps of interest, download and install new Apps, and update the installed Apps.

Each installed App will be displayed as an icon following Add Apps in the gallery. Simply click on the icon to launch the App. Right-click on the icons for other options such as hiding or uninstalling the App.

Some things to note:

  • Click the Add Apps button to open App Center where you can install and update Apps.
  • Right-click on an App icon to Open File Exchange Page (instructions on App use on the OriginLab File Exchange). Some Apps will have a Show Samples Folder where you can find a project with sample data and further instructions.
  • Right-click on an empty portion of the Gallery to adjust icon spacing, add a new tab, sort Apps, etc.
  • The Apps Gallery can be docked to the top of your workspace by dragging the title bar:
    1. Drag the title bar toward the top of the workspace. Guide it to and drop it on he workspace docking button that appears (shown outlined in magenta).
    2. Once docked, drag the bottom edge of the Gallery to adjust width, as needed.

There is a system variable that controls Gallery tab position (@ABO) and two system variables to control App icon spacing (@APPS for horizontal and @APPV for vertical). The shortcut menu Apps Icon Spacing slider will likely be all you need to adjust spacing but for greater control, see the system variable list.

Installing Apps

Two ways are available:

  • Install from App Center directly
  1. Click Add Apps icon to open App Center.
  2. You can navigate through the newly and popular Apps on the New and Popular tab to find your interest, or search for a particular App on the Search tab.
  3. Click AppCenter download button.png button next to the desired App to download and install it directly.

You can also click Find Apps... from the following menus:

  • Analysis: Fitting
  • Analysis: Peaks and Baseline
  • Statistics

This opens the App Center to show only related Apps (e.g. Apps related to Fitting). Click the Download and Install icon AppCenter download button.png next to an App to install.

  • Download from File Exchange page and install manually
  1. Open File Exchange main page. Search the App of interest and open the corresponding web page for that App.
  2. Download the file. Apps are distributed as a single Origin Package (OPX) file.
  3. Drag-and-drop the file onto Origin. Note that you may need to run Origin not as administrator to be able to drop the file onto Origin.

    Once you are on the File Exchange area of the website, you can switch to the main page and use controls such as filters to browse and select Apps of interest to you. Note that in addition to Apps, the File Exchange site also provides other Tools, Templates, Fitting Functions and Example files. Instructions for fetching and installing these other file types are provided in their respective pages.

    To browse only Apps on File Exchange, you can select Apps from the Refine by Type drop-down and click the Apply Filters button.

On successful installation of the App, an icon will appear in the Apps Gallery window. Click on the icon to launch the App.

To sort the Apps on a given tab alphabetically or by installation date, right-click in an empty portion of the tab and choose Sort Apps.

Updating Apps

When a new/updated version of an App is available, a red dot will appear on the App icon in App Gallery window:

To update the app/apps, you can:

  • Right click on the icon of the target App, select Download and Install Update to update it.


  • Right-click on the Add Apps button to select Update All to update all apps which have new/updated versions at once.


In App Center the corresponding item will display an update button AppCenter update button.png to the right of the entry. The Update tab will display the total number of Apps available for update and list the corresponding items. You can click Update All Compatible button to update all of them, or click AppCenter update button.png button next to the desired App to update it.

You can set @AUA = 1 in the System Variables dialog to turn on auto-update for installed Apps that have an update available.

If you directly visit the corresponding web page of an App that has an update available, the Updates section of the page will list what changes have been made to the App in the latest version.

You can also visit the File Exchange main page to browse for available updates on Apps and other file types.

Uninstalling Apps

Uninstalling an App is easy. Right-click on the App icon in the Apps Gallery and choose Uninstall.

Adding an App as a Toolbar Button

In addition to accessing installed Apps from the Apps gallery, you can also add Apps as buttons to a specific toolbar, if desired. Origin provides the Apps button group, accessed from the Button Groups tab in the Customize dialog opened by clicking View: Toolbars.... This dialog contains buttons for all installed Apps. You can drag and drop desired buttons onto the Origin workspace as an independent toolbar, or you can drop them on an existing toolbar.

Package Manager

The Package Manager tool accessible from the Tools menu can be used to create the Origin Package (OPX) file by combining multiple files such as templates, LabTalk Script, Origin C, X-Functions, icon images and DLLs. This tool has specific settings for creating an App. This tool can also be used to install or uninstall Apps as well as modify and repack installed Apps. Refer to the Package Manager documentation for further details.
