Hi,
This is an answer to the old topic:
forums.limesurvey.org/forum/can-i-do-thi...-graph-in-statistics

1. Find the files limesurvey.pal
$ find . -name limesurvey.pal
./themes/admin/Sea_Green/images/limesurvey.pal
./themes/admin/Sunset_Orange/images/limesurvey.pal
./themes/admin/Apple_Blossom/images/limesurvey.pal
./themes/admin/Free_Magenta/images/limesurvey.pal
./themes/admin/Noto_All_Languages/images/limesurvey.pal
./themes/admin/Dark_Sky/images/limesurvey.pal
./themes/admin/Black_Pearl/images/limesurvey.pal
./themes/admin/Purple_Tentacle/images/limesurvey.pal

2. I decided of change all of them, it's the real color pallete, the file has 72 lines that's mean 72 colors bars, change the colors in RGB format, for instance:
74,6,172
219,210,255
10,211,255

3. Erase the cache image files:

• ./tmp/runtime/cache/*.bin
• ./tmp/runtime/twig_cache
• ./tmp/upload/*.png

Please help us help you and fill where relevant:
