Purpose:
This app draws a tangent line at selected point of a data plot in a graph. A smoothing option is available for computing the derivative for noisy data.

Installation:
Download the file Tangent.opx, and drag and drop it onto the Origin workspace. An icon will appear in the Apps Gallery window.

Operation:

  1. Click the icon to open dialog. Change dialog settings as desired and press OK. A vertical line will be added to the graph.
  2. Drag the vertical line to select a desired point on the curve. The tangent line will update as you move the vertical line.
  3. Press the triangle button at the top right of the graph to display a context menu. Select "New Output" to add tangent line at currently selected point.
    You can then move the cursor to other points on the curve to add additional tangent lines.
  4. Select "Preferences..." from the context menu to re-open the dialog to change settings.
    When dialog is open, press "?" button, or F1 to open the help file.

03/11/2019snowliHi @Huang Huaiwei, if u r using Origin 2019, with graph window active, click the Start icon on bottom-left corner of Origin workspace and type "tangent", u will see it. Click it will launch the app. See https://www.originlab.com/Index.aspx?go=Support/VideoTutorials&pid=3326 about how to use Start menu

The the icon also shows in in Apps gallary which is located on right side of Origin workspace. The following video shows old way of adding and launching app from Apps gallary https://www.originlab.com/Index.aspx?go=Support/VideoTutorials&pid=3213

Thanks, Snow

02/20/2019OriginLabHi Wannabe233,

You can expand the App Gallery(if you can't find it, please select "View: Apps" menu to show back) which should be docked at the right-bottom corner of the workspace, and scroll down to the bottom of the window to check if the app is there.

If still problem, please let us know!
Thanks,
Shirley
