Five stars on the Mac App Store

We have gotten great reviews. Click this link to see the reviews on the Mac App store.

"We've been using DataGraph for Mac for the last couple of months. Provided excellent graphs for a proposal, couple of papers, and talks with this lately, and it's very easy, and the graphs look great. Reasonable cost, as well."

— Dr. Matthew Turnbull, Biological Sciences Department, Plant and Environmental Sciences Department, Clemson University (Source: ResearchGate)

"After a few years away from hands-on scientific plotting and after a tour through several alternatives, I've returned to DataGraph -- and found it much better than ever... Datagraph is intuitive, it has everything I need and it produces beautiful output."

— Dr. Patrick Leevers, Department of Mechanical Engineering, Imperial College London (Source: ResearchGate)

Registration Instructions

Licenses purchased from our on-line store will be tied to an email address. Perpetual license holders can register up to three machines for themselves and immediate family members only. Annual licenses are for one user, one machine.

After you purchase a license through FastSpring you need to register your machine(s), and that is explained on the registration page.


Group & Lab Licenses

You can buy multiple licenses for DataGraph, and for the annual licenses you get volume discounts.  The volume discounts are applied automatically and are described on the purchase page.  When you buy multiple licenses you will get an e-mail from us. We will help you either separate the entries into multiple single user licenses or allow you to set up a group or lab pool so that you can manage your licenses and add/remove people/machines.
