Sandwich Posted March 15, 2009 Report Share Posted March 15, 2009 I need to draw a curved graph for some chemistry results, but can't find any software which isn't mathematical (and requires a function) or which offers a curve drawing element to it. I found one called labfit which lets you draw a single curve, but not multiple ones on the same graph. Any suggestions, or ought I to just give up and do it by hand?

moneyfaery Posted March 15, 2009 Report Share Posted March 15, 2009 You mean draw trendlines? [url="http://www.padowan.dk/graph/"]Graph[/url] and [url="http://www8.pair.com/ksoft/"]Graphmatica[/url] (basically the same thing, two different names/interfaces... one is uglier) do the job well.

moneyfaery Posted March 15, 2009 Report Share Posted March 15, 2009 Excel is crap for trendlines... seriously, don't use it unless you want pretty bar graphs or line graphs or something. Reply Link to post Share on other sites More sharing options...
Pod Posted March 15, 2009 Report Share Posted March 15, 2009 Opps, forgot to mention i use excel for graphs and error bars, not trend lines. My bad. Reply Link to post Share on other sites More sharing options...
