From GraphPad Software:
GraphPad Prism, available for both Windows and Mac computers, combines scientific graphing, comprehensive curve fitting (nonlinear regression), understandable statistics, and data organization.
GraphPad Prism was originally designed for experimental biologists in medical schools and drug companies, especially those in pharmacology and physiology. Prism is now used much more broadly by all kinds of biologists, as well as social and physical scientists. More than 200,000 scientists in over 110 countries rely on Prism to analyze, graph and present their scientific data. It is also widely used by undergraduate and graduate students.
This review was originally posted on VersionTracker.com. The reason why I use Prism is to be able to do some advanced statistics and produce graphs for my articles. With Prism 4, you could copy and paste your graphics in Illustrator or any other vector software, ungroup them, and modify them to arrange them into figures. With Prism 5, this feature is gone, it only copy and past bitmap images, and cannot even export a vector PICT file, see below for their explanation (they say it's not their fault). I bought Prism 5 to realize that I actually lost some functions. So, if you want to edit your graphs in an illustration software, stick to Prism 4.
From the Graphpad website (http://www.graphpad.com/faq/viewfaq.cfm?faq=963):
"Prism 5 Mac and PowerPoint or Keynote
With Prism 5, it is not possible to ungroup your pasted graph.
With the release of Leopard, Apple changed its standard for copy and pasting from the PICT format to PDF. As part of this switch, the ability to ungroup was lost. Images defined in pdf format simply cannot be ungrouped by any program we know of.
As part of its Cocoa programming framework that we rely on, Apple no longer provides the software tools/hooks that would allow Prism to copy vector-Pict images to the clipboard (except as bitmaps, which cannot be ungrouped). PDF has replaced PICT as the Mac standard and produces a very compact and clear image. This is a decision Apple made, not us. PICT files encoded QuickDraw commands, while PDF files encode the newer Quartz graphic commands. This switch offers many advantages, including the fact that vertical and angled text now pastes properly. It would be all but impossible for Prism to copy PICT files to the clipboard. We'd either need to use an older programming framework (with other problems and bugs) or recreate our own PICT format (months of work). Even if we did that, Apple has said that Pict files have been 'deprecated' so they won't be supported in future Mac OSX versions.
When you copy a graph or layout from Prism 5 Mac, Prism puts a PDF version on the clipboard.The Mac system also creates a bitmap version of the graph, and puts that on the clipboard too. So now there are two versions on the clipboard: pdf and bitmap (labeled pict). What happens next depends on which program you use to paste:
* PowerPoint 2008, by default, pastes the bitmap image. This takes up more memory and is fuzzier, so it makes absolutely no sense to paste this version. We've notified Microsoft repeatedly about this PowerPoint bug, but it still isn't fixed as of PowerPoint 2008, 12.2.3. There is a simple workaround. Don't use the Paste command. Instead drop the Edit menu, choose Paste Special, and then choose the pdf version of the graph.
* Keynote pastes the pdf version.
* Older versions of PowerPoint cannot paste pdf images, so paste the pict bitmap.
Neither the PDF, format nor the bitmap can be ungrouped. But some programs do let you manipulate the pdf image. In particular, Illustrator lets you increase all line widths using the stroke function.
This review was originally posted on VersionTracker.com. This is one of the better graphing/statistical packages out there on the mac. Their technical support is one of the best I have encountered. Tech support has even helped me to understand my statistical results. Although the graphic capabilities are quite good, they really need to allow more complicated ANOVAs (e.g. 3-way) in the program. In addition, there is not enough scriptability built into the program. But even so, it's probably the best graphics/statistical program on the Mac. Don't even consider SPSS, use this instead.
This review was originally posted on VersionTracker.com. Easy to use, simple but efficient. It perfectly suits my needs. Very didactic software. Additionally, I really like their manual (I'm really bad at statistics and the manual is really descriptive and simple to understand).
A bit expensive though and I'd love to have easier possibilities to play with data formatting directly in Prism. More graph options would be much welcome too.
