1.160 FAQ-817 How do I add drop lines to a 2D line plot?

Last Update: 3/17/2016

Prior to Origin 9.1, adding drop lines to a 2D line plot required the following work-around:

  1. Double-click on your plot to open Plot Details.
  2. Set Plot Type to Line + Symbol (drop-down on bottom-left side). This adds a Drop Lines tab to Plot Details.
  3. Click on the Drop Lines tab, configure your drop lines, then click Apply.
  4. To remove plot symbols for an independent plot, click the Symbol tab and open the symbol gallery (below Preview) and click on an empty cell (bottom of the gallery). For dependent grouped plots (Edit Mode, Group tab), set Symbol Type to Increment = None, and on the Symbol tab, set Shape to 0 No Symbol and click Apply or OK.

Note: These methods of removing plot symbols tend to work better than setting Symbol Size to 0. Also, you may want to read this FAQ on dashed lines in Line + Symbol plots.

Starting with Origin 9.1, you can add drop lines directly to a line plot using controls on the Drop Lines tab of Plot Details.
