DataGraph is a fantastic tool for data analysis and graphing. DataGraph allows you to control every aspect of a graph. Save time by seeing changes in real-time. You can easily add labels and annotations. 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. Export graphs as bitmaps or pdf/eps/svg vector graphics. Export movies as mp4 files.

DataGraph is a tool for data analysis, with a unique visual display. Every column of data and every command is a visual object that can be dragged around, hidden from view, or copy and pasted to other graphs or files. The commands in the program are like drawing primitives that have basic options by default but can be made increasingly complex. By combining commands, you can create amazing graphics and animations.

Our company recognizes the importance of reproducibility and transparency. Every option and action taken on a graph or data set is documented. The program has a data-flow approach, which allows you to go from raw datasets to final publication-quality graphs in one file. Since the data and graphics are all together, DataGraph solves the problem of having processed data or graphics, where the original dataset is in question.

Our goal is to make it easy and fast to accomplish common data analysis tasks that researchers rely on (e.g., linear regression, non-linear curve fitting, t-tests, etc.). Our can not only replace spreadsheets, but also fills the niche between spreadsheets and text-based coding languages. Spreadsheets may be quick and easy to start with, but lack the robustness and reproducibility that scientists and engineers require. Text-based coding languages have the benefit of being robust and flexible, but can be tedious and time consuming to code and are simply not appealing to many students and researchers.

Our approach from day one with DataGraph has been to rely on community-driven development, where feedback from users has shaped the evolution of the program for over 10 years. DataGraph is a mature data analysis and visualization tool, but we continue to welcome suggestions and feedback from our community, and the program continues to evolve with the needs of our users.

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 visit our community web-site for a discussion forum, on-line help, and tutorials. Check out our YouTube channel. Provide feedback or ask questions on the discussion forum or by email.

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

What’s New

Version 4.7.1

Scalar Field Command, Pop-up Notes, Font outlines and more.

Scalar Field Command: Sometimes referred to as a contour map or heat map. A lot of options, both in terms of input data and drawing options.
Pop-up notes: Add documentation to data columns, variables, commands, and groups. Create from the gear menu - Add Note. Auto detects URL links.
Outline options for text labels: Control the color and the width of the outline. Great to make text easier to read on a busy graph.
Improvement for Quick Graphs: Select a column and hit the space bar. Now also works for text columns.
Intermittent points option: By popular demand, can choose to show every other/third etc point in a Plot command.

Many other improvements and fixes throughout based on user comments and feedback. Thanks for all the questions and suggestions on the community board (shortcut in the Help menu)

Datagraph 4.5 Bombs on my OSX 10.9.5

Datagraph is a wonderful application, and I love it (I have used it up through version 4.4 for years). Datagraph says it is compatible with OS 10.9.X and above. However, when I upgraded from version 4.4 to 4.5, the application crashed and I was unable to get it to run prperly on my OS 10.9.5 system. I reverted by to Datagraph version 4.4, and everything is well again. So, if you’re still running OSX 10.9, be wary of the 4.5 version of Datagaph.

UPDATE TO MY REVIEW: DataGraph 4.5.1 fixed my problem, and so I have upgraded my rating to 5 stars. Many thanks to DataGraph tech support for their rapid fixing of this error.

Developer Response ,

This is fixed in 4.5.1. Please try it out. Please report bugs either on the community board or through our help e-mail. Thanks for using DataGraph!

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.
