![]() To reset the Grid Range and Theta Range, however, you must call up and use the Defaults buttons in their own dialog boxes. Set all the options to their default (as specified by Graphmatica, not your GRAPHMAT.INI file or user preferences) settings. This option is enabled by default in the French version only.įorget the changes made in the Settings dialog box. Shade Inverse of solution for inequalitiesĬheck to shade the portion of the grid that is not in the solution when graphing inequalities. On by default.ĪutoRange-Adjust y-axis to show new equations When it is on, you can also type in the maximum number of equations you would like to redraw. Mark to show the Point tables window and show calculated points graphed while graphing. Mark to display warning error messages while graphing. This option has no effect on inequalities they must be drawn with lines, or the shading will "leak out" of the proper region. Not recommended with full gridlines graph paper on. This option may speed up drawing somewhat, although visibility of graphs is reduced. When you zoom in, the grid range is shrunk by this factor when you zoom out it. Mark to draw only calculated points on graphs, not the segments connecting them. The General tab in the Global Settings dialog box allows you to control. You may also optionally increase the width of these wide lines (by default 2 pixels) for extra visibility ![]() This option has no effect when Draw graphs with dots, no lines (below) is selected. Mark to draw graphs with extra-wide lines for better visibility (slows down graphing and redrawing not recommended on slower machines). This is set by default you should probably only uncheck it if you want to configure the defaults for a network installation manually and prevent students from changing the defaults on individual workstations. Mark to save all global options to graphmat.ini when you exit Graphmatica. a factor of 1.05 changes the dimensions of the screen just slightly).įineness Factor Allows you to change the fineness factor, which balances graph smoothness with computation time. ![]() Decimals greater than 1 are valid, though (e.g. Zoom factors <= 1 are not allowed because they produce meaningless results. Zooming out by a factor of two makes the grid twice as wide and high. For instance, with the default value of 2, zoom in cuts the width and height of the grid range by half. When you zoom in, the grid range is shrunk by this factor when you zoom out it is increased by the same factor. Use Tools/Find Intersection to automatically find the points of intersection. Use the Default Grid button to return to the normal view. Zoom Factor This value controls the behavior of the Zoom in and Zoom out commands. There are two ways to zoom in and out : - View/Grid Range - change the grid-range by typing limits for x and y - Mark and Zoom - hi-light an area then click the zoom button. Following is a description of its controls, from top to bottom: The General tab in the Global Settings dialog box allows you to control many of the options available in Graphmatica.
