Dear All, When I use set term png, it always gives the following warning Could not find/open font when opening font "arial", using internal non-scalable font and the plot generated is quite ugly as compared to say what python generates. I would like to know how I could possibly remove this warning, and improve the plot quality. The system I use is linux, more details please let me know which command to use to find it out. Thanks, Sincerely, John |

I have the same issue. I "solved" it by using pngcairo instead of png. For some reason, pngcairo finds the macOS fonts, while png appears not to.

Dear Ethan, Thanks for your help, I don't want to bother the system manager, thus I turned to the other way. But gnuplot does not return and entry for "help fonts gd" or other similar helps, is there further help?

The cause turned out to be the compile options for libgd, which by default was being built without freetype, as I understood it. The fix- on a Mac, using the homebrew package manager- was: brew install libgd --with-freetype May help someone?! ~T |
