How can I change the color of the background in tkf file viewer ? Now the background is black and the plot is white. I want a white background and color plot
One of the menu's in the TKF graphic viewer has an option to change the background color.
However, the PQG/TKF graphics are deprecated. I would recommend that you transition to the new graphics. They look much, much nicer as you can see here.
We on the forum are happy to help people update their GAUSS graphics. If you would like some help with that please post a question!
