[Question] Help with Gimp or Illustrator

[drawn_inward]

Hey all,

I want to clean up a figure for a poster of some of my data. I have access to Gimp and perhaps Illustrator.

There are 4 lines that pinkish/purple that I would like to change to different colors; a different color for each line. I tried the bucket fill, but those "waves" are actually individual bar graphs so it only fills one bar at a time.

I don't necessarily want you to fix it for me. If there is an easy fix, could you help me out? Please teach me like I am a child 'cause I am quite unfamiliar with these programs.

Thanks in advance!

In GIMP, you can do a rectangular select surrounding the graph you want to change and then open the Colors/Hue-Saturation control. Then, adjust the Hue slider to change the color. Don't adjust the other sliders as this might change the white background as well.

This filter is found in the image window menu under Colors → Map → Color Exchange.

That's probably much easier than the suggestion I was going to make about palette swapping in indexed mode.

I experimented with it using the method I suggested. It's not perfect, but I think it's close.
