Excel and Powerpoint have been banned for figure preparation. Converted my lab over to GraphPad Prism. A very well designed graphing and statistics program. Love several features including the ability to apply standard dimension formats for charts, and wand tool to covert charts to exact format used previously. Application of statistics to data is facile, also a wand tool to apply the same statistics to multiple tables. Grateful to Assay and Drug Development Technology for their requirement (recommendation?) to use this or similar programs in figure preparation. Powerpoint never worked well for figure preparation and conversion to vector-graphics format, for use with illustrator was a nightmare. Now we just start out using a freeware vector graphics program or Adobe Illustrator directly. Greatly speeds up manuscript preparation.
P.S. I have no financial relationship with GraphPad Prism, but it is a good product so therefore my endorsement!
