File:Double X Independent XY 01.png

Data Requirements

Select 2 sets of X(Y) data or at least 4 columns to create double X plot. The 2nd set of X(Y) use indepenedent axes.

Creating the Graph

Select required data.

Select Plot > Multi-Panel, Multi-Axis: Double X - Independent XY from the main menu.

Template

DblY_ColSymb.OTP (installed in the Origin program folder).

Notes

This graph contains two layers which have independent XY. By default, bottom X and left Y construct the first layer, top X and and right Y construct second layer.

To select data columns and plot them into two layers:

  • When X columns in selection>=2, 1st set of X(Y) should be in 1st layer, 2nd set in 2nd layer, 3rd in 1st layer, and so on.
  • When X column in selection<2, columns will be consider as XYXY, 1st pair of data columns in 1st layer, 2nd in and layer, 3rd in 1st layer and so on.
  • When number of columns in selection<4, a message box will pop up to remind you selecting 2 sets of X(Y) data or at least 4 columns.
  • When number of columns>=4 and X column in selection<2, if number of columns is odd number, then we can treat last column as Y column.
