Hey JR,
First, to change the live plotter preview colors in Axis you have to copy the contents of the file:
/usr/share/doc/emc2/axis_light_background
(this is where the color values are stored)
into the file:
then you have to merge it using:
You may have to create the .Xresources file if it is not there.
Changing the text colors for the rest of the application is a little more in depth. If you have never programmed in TCL, I would suggest looking at
effbot.org/tkinterbook/ . I used it a lot.
The majority of the interface code is found in:
/usr/share/axis/tcl/axis.tcl
Read over that code. I can give you more specifics where to look if you tell me exactly what you want to change.
