DataThief is compatible with System 7 and the author DataThiefĪnd manual modes, so you can do the tracing yourself if it doesn't seem toīe getting it right. Handle X-Y graphs, although in both PICT and Paint format. It is limited to reading in data from a scanned graph and appears to only News of another application that performs a similar task.

A floating pointĬo-processor is not required on 68k machines, but floating point arithmetic G&G is 32-bit-clean, and runs on 68K and PowerPC Macs. To have a release for BeOS and Win95 around August, 1998. Groups & Graphs is currently available for Macintosh computers. Projective drawings can be saved as text files for export to other ItsĪutomorphism group orbits can be reflected in the projective drawing. The incidence graph of a projective drawing can be constructed. DrawingsĪ point or line in a projective drawing can be sent to infinity. Panning and zooming of projective drawings is available. Lines and points can be immobilized if it is desired to restrict The entire drawing moves and flexes, allowing a configuration to be seen the Desargues and Pappus configurations, and many others.Ĭlick on a point or line in a projective configuration, and move it. Real projective planar configurations can now be constructed in G&G,Įg. Keep in mind that large graphs take longer to display and compute with, The maximum allowable order of a graph is now set at 4096. The arrow keys can be used to scroll through a group window Vertices of a graph can now be selected according to their degree Ham cycles - G&G will produce a file of all ham cycles in a graph. On which the selected perm P acts cyclically. G&G tries to find the longest cycle in the graph Graphs with non-identity automorphism groups can now be drawnĪutomatically, using the symmetry of a selected permutation P in theĪutomorphism group. ![]() Kempe chains can be constructed and flipped, for studying the Graph can be coloured, either with a paint brush tool, or automatically.
