Description:

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.

08/16/2018OriginLabch1124858780 用户,你好。实用 Tangent App 时, 不需要先选取一个点再按“Enter”键。 你只需要选择图形为当前窗口,然后点击 Tangent App 的图标。在弹出的对话框中,点击 OK 按钮,Tangent 工具将会显示在图形上。 然后你可以拖动垂线(默认是红色的)到你所需要作切线的点。想了解更多具体的说明,可以在打开的对话框时,按F1键,查看帮助文件。
