LINK QUICK REFERENCE ____________________ KEY: % (type it) Menu1-Menu2-Menu3-option(select this cascade of menus with left button) <1st> (left button) <2nd> (both buttons (held simultaneously)) <3rd> (right button) (left button with shift key down) CREATE VERTICES <3rd> (click where you want it) CREATE EDGES <3rd> (click on endpoints) SELECTING (HIGHLIGHTING) VERTICES AND EDGES <1st> to add to selection, to grab a region of objects, <1st> in an open area and drag mouse DELETING VERTICES AND EDGES select objects to delete, type "x" (no quotes) *or* using menus: Edit-delete CLEARING SCREEN menus: Edit-clear COLORING VERTICES Select with <1st>, menus: Attributes-color COLORING EDGES Select with <1st>, menus: Attributes-color MOVE VERTICES <2nd> (careful to click both buttons at the same time) (if you mess up and inadvertently click the <3rd> button first, you get the beginnings of an edge segment. Click <3rd> in a clear area of the canvas to get rid of it.) CURVE EDGES <2nd> (after clicking on edge label - see LABELS below for retrieving) LABELS menus: Attributes-Labels-show all (displays all labels) (there are many similar options) SETTING LABELS menus: Attributes-Labels-set (another window will come up prompting you for a label. It may appear off the visible part of the screen. Use the "radar" in the upper left-hand corner of the screen to locate icon of new window, scroll using track ball to get there). CHANGING VERTEX SIZE menus: Attributes-Size CHANGING EDGE WIDTH menus: Attributes-Width LOADING GRAPHS FROM FILE menus: File-load SAVING GRAPHS TO FILE menus: File-save (you should keep to the "file.g" naming convention) CREATING EMPTY DIRECTED GRAPHS Find the window that has two buttons: Tutoral and Graph Windows. Graph Windows-Graph-Directed-No Multiple Edges (this should bring up a new window containing a directed graph) CREATING EMPTY UNDIRECTED GRAPHS Find the window that has two buttons: Tutoral and Graph Windows. Graph Windows-Graph-Undirected-No Multiple Edges (this should bring up a new window containing a directed graph) ************************************************************************* *********NOTE: GENERATION IS SLOW. BRINGING UP A C-5 or K-5 is********** probably acceptable for class, but a 6x6 grid takes over one minute to load. I'd suggest creating one before class, then moving it to another "room" in the windowing system using the <2nd> button in the icon box in the upper left-hand corner of the screen. Clicking with <1st> changes "rooms." ************************************************************************* GENERATING CYCLES menus: File-Generate-Graph-Undirected-Cycle (a window will come up prompting you for the number of vertices) GENERATING COMPLETE GRAPHS menus: File-Generate-Graph-Undirected-Complete Graph (a window will come up prompting you for the number of vertices) GENERATING GRID GRAPHS menus: File-Generate-Graph-Undirected-Grid Graph (a window will come up prompting you for the number of rows and the number of columns) ALGORITHMS Don't seem to show up to well on lcd. DFS works, but Kruskal animation isn't intuitive yet. I would just use the mouse to click and describe algorithms manually. LAYOUTS menus: Layouts-Circle Layouts-Random Layouts-Spring Layouts-Bipartite (mainly useful for hypergraphs)
