Graf has been developed over the years as in in-house plotter for astrophysicists, and scientists in general by Prof Ralph Sutherland at Mt Stromlo Observatory.

The philosophy is that the data may come from any source in basic text form with notional columns. Graf reads the files on the fly, looking for numbers to plot and ignoring text it can't plot. This makes it very useful for when data is not conveniently already in a column-spreadsheet format, although it can happily use .csv files as well.

A data window is opened and multiple setups with columns, colours, markers, line styles and transformations can be defined.

A plot window can plot all the data sets from any number of data windows, applying a plot style and plot transform, including affine 3D rotations.

Stat windows can perform basic numerical analysis of the selected data sets, including basic statistics, linear and non-linear regressions, splines, FFTs, convolutions and histogram analysis.

The plots can be combined using drag and drop between plot windows, and the output PDF are small and high quality, and have been used in mainstream scientific journals and PDF LaTeX documents for many years.

Graf0 runs on older machines often found at universities without upgrade processed, and will work back to system 10.9, Mavericks. A new Graf version is in development to take advantage of new macOS features and will require newer operating systems, but will maintain backward file compatibility as a priority.

Graf is highly sandboxed and no network or access to any files or hardware except general text, Graf and output graphics.

Graf 5.2.2 Update
2020-07-31 Version History
OK Graf is complex and light on documentation - we are working on improving that over time as Graf X is developed too. As an 'in-house' application for many years training has be by word of mouth or short tutorials. Now some of that will be collected on the support site. It remains a technical application and will challenge experimental users not afraid to try buttons. *Graf is a plotting tool for largely pre-prepared data in TEXT form of nearly any format, from spreadsheet csv to other experimental or computer generated data, It should handle any UTF-8 text file from linux, mac or PC origins, please report any text files it cannot read. * Questions will be answered as soon as time and resources allow in these difficult times, and independent experimentation is encouraged. 3D plotting and advanced analysis will eventually be covered as the help is expanded. Contributed examples will be properly considered and credited if used. Translations to other languages are welcomed. More: * Added an example driven tutorial by Dr David Nicholls to the support website via the help menu. * Added the data and plot data and files for the hydrogen line ratio grid in the example screenshots for the user to experiment with on the website and via the help menu. * Added a direct link to the support website via the help menu. * Internal icon tweaks in preparation for coexistence future Graf X. * More examples and guides will be developed and added to the support website to help unravel this complex tool fully. * More than a million points have been plotted in a single plot with Graf so it is useful for high resolution spectra as well as simpler plots like histograms.
