How can I use Didger to digitize a graph that has a non-linear X axis, but has intervals of linearity?

Didger 3 was not designed to easily handle non-linear axes. You have two options when it comes to digitizing non-linear axes:


  1. You can digitize it into one PJT file. You will have to digitize a section with a linear portion of the X axis, then change the project limits (to reflect the entire project), move the map, recalibrate the tablet, and digitize another section that has a linear portion of the X axis. This file will make a linear X axis, ranging across the entire X axis min/max values, and your digitized objects will be spread across it.

  2. You can digitize the profile into a number of PJT files - each one containing a section of the profile that has a linear X axis.


The most recent versions of Didger can handle non-linear axes.
