Screen Shot and Video:

This app can be used to insert LaTeX objects in worksheet cells, graph axes titles, legends and text labels.


NEW App Features in version 2.0 (requires Origin 2017):

Installing and using the LaTeX App version 2.0 in Origin 2017 allows for the following features:

  • Insert a LaTeX object into worksheet column label row cells, axis titles, and legends.
  • Arbitrary text labels on either graphs or worksheets.
  • Easily generate the LaTeX markup for built-in fitting functions via a button in the App dialog


Installing the LaTex App allows you to also add LaTeX objects to worksheet column label rows, graph axis titles, and graph legends. Also, you can add the LaTeX markup for all built-in fitting functions via a simple click of a button in the App dialog.




You must have the following installed on your computer before you can use this App:

  1. MiKTeX
    You can download MiKTeX from:
    Note: During MikTex installation, choose All Users (default) instead of This User Only.
  2. OAutotrace
    You can download OAutotrace from our OAutotrace page.

After installing the aforementioned components:

  • Restart Origin if already running.
  • Download the file LaTex.opx from this page, and then drag-and-drop the file onto the Origin workspace. An icon will appear in the Apps Gallery window.


  • App version 1.71 or later requires Origin 2017 SR0
  • App version 1.4 requires Origin 2016 SR2
  • If you have installed the earlier version v1.2 of this App,  please follow these steps:
    • Uninstall the App (right-click on the icon and select Uninstall)
    • Close Origin
    • Navigate to the user folder, such as:
      C:\Users\<User Name>\AppData\Local\OriginLab\93\TMP\textemp\,
    • Delete the temp files
    • Restart Origin and then install the new version of the App


  1. With a graph window active, click the "LaTex" icon from Apps Gallery window and the LaTex Equation Editor dialog will open.
  2. Input LaTex script in Equation edit box. Click the Preview button to preview the result .
  3. Click OK button to insert the equation into the active graph window.
  4. To modify the equation, you can double click on the inserted equation to re-open the editor.

Additional Notes:

  • The equation in the graph can be rotated, and the color can be changed using the Format toolbar.
  • Exporting the graph as EPS or PDF will maintain the equation as a vector object.
  • When clicking the Preview button for the first time, you will experience an extended delay (perhaps in excess of a minute) as the App fetches additional packages from the internet. The update status is shown on the Origin Status Bar at the bottom of your workspace. This delay will occur only on first time use. Subsequent operations will be much faster.

08/20/2021OriginLabHi Lirry_LR,

LaTex App is built based on TexWork of MikTeX. Please send us a sample to ry, or you can download TexWork to try macro package yourself. If you find any macro package TexWork can use but App cannot, please let us know.

Thank you.

08/19/2021Lirry_LRI only want to know how the app uses the macro package, or how to modify the font of the formula

08/14/2021yzyzy96it is really productive.


03/08/2021JacquelineheHi dengcy,
Thanks for your suggestion. Now this app does not support TexLive. We will consider support it in the future version.

I re-installed OAutoTrace using the *.msi version instead of the *.exe version. It seems to work now!

01/29/2021oi372I have the same problem as Thomas. Whenever I type LaTex code Origin shows me an error message that the tracing failed. I installed MikTex and OAutoTrace before installing the app. The app is recognized but it fails to render the LaTex code. I run Origin 2017 64bit b9.4.0220.

I received the following error message:
[01/29/2021 09:35:35]
SYSTEM.FONT.TRANSPARENCY: object property not found!
SYSTEM.LEGEND.TRANSPARENCY: object property not found!
Failed to execute Autotrace. Please contact OriginLab.

Looking forward to hear from you.

Kind regards

01/28/2021OriginLabHi ThomasKure,
Please make sure that you have install MiKTex and OAutotrace like the Prerequisite section above.
If it still doesn’t work, could you please tell which version you are using and what the error message is?
