See what one of our long-time customers has to say:
I started using KaleidaGraph over 30 years ago, as a much welcome upgrade to the venerable Cricket Graph, which I had used on an old MacPlus since 1986 - maybe started with KaleidaGraph when I got a Mac II with color monitor, although details not so clear as it was a long time ago. Since then I have introduced it to numerous PhD, Masters, and undergrad students, so have hopefully contributed somewhat to your growth. My first intervention was always to point out, when someone presented me with a horrible Excel 'chart', that it would really be much wiser to do such things with KaleidaGraph - nobody ever told me I was wrong about this! Best wishes for the future.
