I work with reams of matrix-based data and appreciate having the right tools. KaleidaGraph's the right tool for data handling, joining, filtering, and plotting for final viewing, as well as report generation. Everyone should have a copy!
Dr. Marc PopekEngineering Research Associate, University of Nevada Las Vegas
I had been looking for graphing software that would, on one level, allow me to produce typical graphs, but, on another level, allow me to flexibly modify aspects of the graph in specific ways. The major software choices were limited. I thought I had to make do with what I had until I tried KaleidaGraph. This is a fantastic little piece of technology that is brilliant.

Our campus’s entire science division switched to KaleidaGraph because it is powerful, easy for students to quickly learn, and it allows them to create every type of graph they need.
