I had some trouble using existing graph tracing programs, got frustrated, wrote my own damn program hacked into the middle of an existing app that had no real UI and needed to be run from a debugger in order to capture the output. I wanted to share it, but decided it would be easier to write it from scratch than fix up the existing one, and have finally completed that.

Basic usage is to Open an image file, click on the line you want to trace, click + drag the purple boundary markers where you need them and set the Axis values appropriately depending on where you placed them, then Save the output as an frd or zma file.
The Bounded Trace setting can be enabled to limit tracing to within the purple boundary markers. This can be used, for example, to trace off-axis portions of FR graphs where the line begins as black and then splits into multiple colored lines. First trace the black portion, then enable the bounded trace option, move the boundary markers around the section of the image where the split colored lines are and click on the line you need to trace. The points outside of the bounds will remain and the points inside the boundary markers will be replaced with the new trace. Once you have the trace you need, move the boundary markers, set the axis values and save the file.
Clicking in the center of a line will help produce the best trace, and increasing the zoom level on the zoom panel can help make it easier to click the right point and set the boundary markers accurately.
There's not too much to it, really. No guarantees that it will work for you, but if it does, please let me know. And if it doesn't, please let me know.
