I am starting up a website that needs a lot of sophisticated multi line charts. I see two top candidates for the job
Does anyone have any recommendations or preferences on this decision?
Google charts: You will need to call out to google every time you need to plot. Is it acceptable to do this from your website?
Control: Flot is the clear winner in this category, as you have a very high degree of control over plots. Also, Flot is pretty fast! I have used it personally, and once you get the hang of the API, it is great. Further, there are many 'plugins' that can be written (and some are available) for flot. I think this is a great feature.
Overall, I would vote for Flot.
