Yes. We are currently rewriting the software for a new development platform which will allow us to provide a 64-bit version of KaleidaGraph for both Mac and Windows. The process is ongoing, and we do not have a release date for a 64-bit version at this time.
KaleidaGraph is a thoughtfully designed graphing and data analysis application for research scientists, as well as for those in business and engineering fields. It produces publication-quality graphs, and easily converts the most complex data into a functional display.
