The simplicity to create charts, I like how easy it was with this program compared other programs out there which are more complex in their features but not as simple or intuitive when using them! Not much dislike about anything so far; however if you're looking into creating some bar/line chart then definitely check these guys' products first because they have an incredible product line-up available here at no extra cost - unlike many companies who charge ridiculous prices just cuz its called "Automatic graphing". We've been able use our own CSV files instead of having users download excel spreadsheets every time we need one created (which can be problematic).
