DataGraph is a combination graphing program, statistical tool, and drawing program. Use DataGraph to visually explore your data, create publication quality graphics, and as a presentation tool.

Enter or import data from huge text files or Excel spreadsheets. Use and draw mathematical expressions and descriptive statistics. Perform function fits and multivariable fits. Create histograms, box and whisker plots, and violin plots.  

Manipulate tens of millions of data values in real time, with changes done live as you vary sliders and select menu options. DataGraph has a powerful pivoting action that allows you to drill into the data and slice and dice it to explore your data.  

You will no longer need to create a graph in one program and annotate or refine it in another, like Illustrator. Do it all in DataGraph. Create publication quality graphs with ease and control every aspect of the graph or let DataGraph handle it for you.  Export as bitmaps or pdf/eps/svg vector graphics.

A free trial is available from the DataGraph web site, so it is easy to see it for yourself before you purchase.  Be sure to view the manual that is available through the Help menu, check out our YouTube channel, and ask questions by mail or on the discussion board.

DataGraph is created by the same company that made DataTank, a high end scientific application which won the Apple Design Awards in 2005 as the best Mac OS X Scientific Computing Solution.

great app for charting large data files


I have to analyze failrly large data sets in my line of work and excel (while being awesome) just does not work with anything that has more than 100K rows.
UI is a bit.. well unusual, but one can get used to that. There are quite a few nice features, but be prepared to spend few hours learning all the features.
Developer is very responsive.
Overall this is a good supplemental tool for data scientists.

Powerful, customizable, a bit quirky


This app is a godsend after struggling with the many data-display shortcomings of Excel and Numbers. It lets you customize nearly every aspect of your outputs, and with a refreshing layers-style interface for controlling and formatting each visual element. As other reviewers have noted, the interface elements are quirky and often nonstandard. But the rewards of spending a bit of time to master this app are vast.

Nothing Like It


Hands down…the best graphical software one can get on the Mac. Version 4.0 rocks!

I've searched for years and years for the right Mac OS X plotting / graphing program. I've been an ardent Kaleidagraph fan, from my earlier OS 9 bouts with Deltagraph and CricketGraph. For simple schoolwork to sophfisticated journal-style graphics, it was always a chore to prepare exactly the graphic representation of my data with everything in the past (albeit KG was pretty good). Now I've played with DataGraph and discovered it is truly the Mac OS X app extraordinaire! You really need to download the demo version from the web site, play with it with an intent to understand what data graphing and function fitting should be without the underlying programming in something like Plot or R, and you'll quickly realize this app can't be beat. There will always be one or two small things that I as a single user would like to see different or added, so we'll see how well the program is updated (their website suggest 2-3 per year) but I'm happy to say I look forward to using this program quite often. Price is steep, but once again, when you realize what you've just bought and what it can do, I think you'll find it is a fair price. Let's hope some simple 3D graphing is added from their academically-bent professional DataTank.
