![]() Graphmatica is a powerful, easy-to-use, equation plotter with numerical and. You can also easily change the range using only the mouse see Selecting a Range with the Mouse. The following is an introduction for producing simple graphs with the R. ![]() You can also see the x y xy x y x, y-planewhich is now the input spacebelow the graph. a powerful, easy-to-use, equation plotter with numerical and calculus features: Graph Cartesian functions, relations, and inequalities, plus polar, parametric, and ordinary differential equations. Select the Reset button to reset the range to the default grid saved in your graphmat.ini file (the preset default is (-8, auto) - (8, auto)). The video shows this graph rotating, which hopefully will help you get a feel for the three-dimensional nature of it. If you want to show the same range both above and below the x axis, you can leave both top and bottom coordinates blank, and they will be generated to fit the current aspect ratio. If you see the orange graphics highlight frame, the entire graphic is selected. The text description of the plot was entered using the text tool. Select the text tool, click a graphic, and then enter some text: In the graphic below, the math tool was used to enter the plotted function. Numerically solve and graphically display tangent. The best alternative is Wolfram Alpha, which is free. There are more than 25 alternatives to Graphmatica for a variety of platforms, including Mac, Windows, Linux, Online / Web-based and iPad. Data plotting and curve-fitting features. Graphmatica is described as Is a powerful, easy-to-use, equation plotter with numerical and calculus features: and is an app. If you pick the least significant coordinate to AutoScale, you can match the other three exactly, framing your graph almost as well as a custom range, but with a more natural aspect ratio. You can also add text to a graphic by using the text tool. is a powerful, easy-to-use, equation plotter with numerical and calculus features: Graph Cartesian functions, relations, and inequalities, plus polar, parametric, and ordinary differential equations. To create a "square" grid where both x and y axis have the same scale, just leave any of the four coordinates blank and mark the "Autoscale fourth coordinate" checkbox, and the fourth coordinate will automatically be scaled properly to fit the other three. The new grid may be somewhat expanded or compressed depending on the aspect ratio, but it will show the part of the graph you're interested in the best possible detail. To create a "custom" grid, estimate the top-, bottom-, left- and rightmost extremities of the graph, and fill in these values in the appropriate edit fields. Or, you can constrain one or more of the coordinates to produce a graph with a square aspect ratio without actually figuring out all of the values by hand.Ĭhoose the Grid Range item from the View menu to modify the grid. Graphmatica allows you to adjust the start and end of the x- and y-ranges independently, so as to create a perfect fit for whatever function you are graphing.
