Running the following command line -
engauge -import 'eng_digimage.png' -axes 0.0 3000.0 265.0 295.0
The YMIN value of the -axes is interpretted as 0 instead of 265. It appears that the axes are correctly identified during the inititiation (lines pass by and the axes become colored) and everything works fine if the axes are set manually when running without the axes option. I think this could be repeated easily with any plot; but, the specific plot is attached.
This feature of being able to pass in the axes points makes for a fantastic inteface from iPython/matplotlib.
Thanks to the developer(s) for this wonderful app!
