I am using OriginPro 8.5.1 SR2. I am trying to graph chemical data (x-axis) versus depth below surface on the y-axis. I want the scale to be from 12625 to 12345. I can make Origin do that. However, I keep getting a default increment of -50. When I try and change it to -10, there is no response from Origin. I can't find anything in the help module to help me figure out how to make this work. This is the first time I haven't been able to get Origin to work.
When the gap between major ticks is too narrow to display, Origin won't accept the value. In my test, the minimum in your case was -14. I suggest you to set the Increment to -20, and the number of Minor Ticks to 1.
