How to set two different scales on the same axis

Some Origin users wanted to have two different axis scales on a same axis like the following sample X:

Here, the negative X region has the millimeter scale, but the positive region has the centimeter scale. Placing a zero-gap axis break in the axis achieves such axis format. The following is the essential procedure to do this.

 

1) To make an axis break, in the Axis dialog, Breaks tab, set the Number of Breaks to 1. Also, as we don’t want to show the break’s wavy marks, set 0 to Break Half Length .

2) Also in this Breaks tab in the Axis dialog, set both Break From and Break To fields to the X position of the scale changing place, 0 in this sample. Here, the same value for both Break From and Break To¬† makes a zero-gap break. Also, to place this position at the middle of the X axis, turn OFF the Auto Position check box, and enter 50 (in %) at the Position field. You can set the scale increment after this break by pressing the “Details…” button. (See the above image.)

3) Finally, in the Special Ticks tab, you can put the (major) tick labels (here, -2mm, -4mm, -6mm) at specific X positions.

Note that the same technique can be used for the Y axis, and the following sample can be created by this tutorial:
