“There are still some extremely frus­trat­ing lim­i­ta­tions though. First of these is the res­o­lu­tion of draw­ing the graph. I’m sure for most graphs the default res­o­lu­tion is fine, but when cre­at­ing these pat­terns you need tiny incre­ments. Tiny tiny ones. If the line is going from one side of the graph to the other and back again a thou­sand times in a cou­ple of radi­ans, you don’t want the graph pro­gram to start drop­ping line seg­ments, or cor­ners, or any­thing really. Gra­pher does allow you to increase the res­o­lu­tion, but it’s not sticky — change any­thing in the equa­tion and it pops right back to the default. Every. Sin­gle. Time. The same thing seems to hap­pen with the line thick­ness too — I wanted all the designs to be at 0.1, but it kept chang­ing it back to 1.0. Frus­trat­ing! There are a cou­ple of other UI things I’d change, like hav­ing an option to keep axes at 1:1 ratio to each other, even when you resize the window.”
