  Engauge Digitizer - Multiple Coordinate Systems In One Graph
A graph with multiple coordinate systems, each defined by a pair of x/y 
axes, can be digitized in Engauge.
The following steps digitize a graph with multiple coordinate systems:
- Obtain an image file (bitmap, jpeg or other) showing multiple coordinate systems
- Import the file using the Import(Advanced) menu option:
  
  - File/Import(Advanced) menu option
- Select the coordinate system count
- Click on Ok
 
- Select a coordinate system using the dropdown list in the Coordinate System Toolbar.
- Digitize the currently selected coordinate system using the same steps used for a 
a single coordinate system
- Repeat the previous two steps for each coordinate system
