DESCRIPTION
KaleidaGraph... Graphing and Data Analysis - Don't just graph your data - learn from it!
KaleidaGraph is an award-winning graphing and data analysis solution that is rich in features yet affordably priced. This unique application distinguishes itself in the technical marketplace with its powerful curve fitting, precise plot customization, helpful stats, a short learning curve and an affordable price.
RJBAILEY I used to love KGraph but got frustrated with the slow pace of development. The one thing that kept me coming back was the user-defined curve fit feature I didn't find elsewhere among similarly priced software. If this is important to you, you may wish to invest some time in learning about gnuplot's curve fit options that are more powerful than KGraph's, although with a bit of a learning curve. But hey, it's free. (Version 4.1.1)
PP I have used KG for quite a long time, and (still) like it very much, but to ask $59.95 for upgrading into version 4 does not make any sense to me. As a loyal long-term customer of KG, I am not willing to spend so much money on (basically) cosmetics. Although I have already started checking other graphers on the market, I am still curious to hear from the developer why have they decided to lose me. (Version 4)
JOHN A long hoped upgrade but quite disappointing. Only cosmetic changes (menus are still the old MacOS 7 design, while the interface is WinXP-like. Also some graphical problems under Tiger in the "speadsheet" sometimes. Just don't see why it is a "worth-have". Not worth the upgrade; Please, give us a real update. Too bad from such a company. Money is not that easy. (Version 4)
