What our customer's say!

"a solid graphing and fitting program", I use Kaleidagraph for plotting and fitting data in the research group I work in. Kaleidagraph produces good plots without the "graph junk" that other plotting programs seem to insist on adding to graphs. The new version runs natively under OS X and can handle much larger files than version 3.0.x. Kaleidagraph can read data from Excel files and text files with Mac or Unix line endings. Plots can be exported to various graphic formats including JPEG, PNG, and high resolution TIFF. Another useful feature is that data can be saved in a plot file and extracted from the plot later. It comes with several built-in fit functions and allows you to define your own fit function. All in all, I find Kaleidagraph to be a solid plotting program with good fitting capabilities.
