What about DeltaGraph 6?

Delta graph is a great concept - in theory, you have the flexibility to change colors, symbols, line thicknesses etc that you expect from a scientific graphing program. It also allows the import of other images (like jpgs and tiff) right onto the graph so making a single figure with multiple panels does not require the numerous steps - also great for posters and PPT presentations. It also runs on both PC and MC platforms, which is a great idea for large labs or institutions that want some continuity. However, similar problems on both. It is really only even rated as high as I rated it, because it is better than most of what else is on offer

There is really not that much other choice (oh , woe the loss of cricket graph)


However, delta graph is buggy, crashes often for no apparent reason (I have been using it for years, so this is not a single version issue) - the legends sometimes appear miles away from your graph, it can not do really scatterplots, and it can not longer directly export to tiff or jpg - which was one of the best features.

Perhaps worst of all, tech support has been declining. At one time it was possible (albeit unlikely) to get phone support. There is not even that option anymore. I have had support tickets going for weeks before I get any answer, and one that has been put in 3 times more than a month old (world record).

At about 200-300$, not cheap certainly, You expect some basic tech support, a stable program and the advertised features for which you bought the program to work - and things to get better over time, not to decline, which is a bad sign.

Summary - good concept, good potential, but in practice frustrating and disappointing.
