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
