Java Applets do not have access to the clipboard. To copy images to the clipboard, you need to run this program on your local machine, outside your webbrowser. You may run this program on your local machine (while not on the internet) by downloading the file JavaView.jar (715K), and one or more of: Grapher.jar (55K) (3d Grapher), Grapher2D.jar (45K) (2d Grapher), or GrapherODE.jar (24K) (ODE Grapher),

Make sure the two files are in the same directory, then double-click on Grapher*.jar. Running the program on your local machine may require a download of a Java Virtual Machine if you do not already have one installed

Please note JavaView.jar is subject to copyright restrictions. Please view the copyright notice from the creators of JavaView. Running the Grapher on your local machine also requires a free registration of JavaView

Features and Version History

3D Grapher

Added Jan 8, 2006

Show Edges: checkbox for showing edges on surfaces
Color By: set whether surfaces are colored by XYZ values or Z values

Added Nov 3, 2005

Parameter sliders: put constants a,b, and/or c in your equation, and use the provided sliders to alter the value of the parameters.
Time animation: put "time" in your equation to animate your graphs. Min and Max can be specified in the boxes given. Use the Start/Stop button to start or stop animation. Press F4 while hovering over the graph to get a more detailed animation control.
Views: Under the Bounds tab, you can now switch from a perspective view to an XY, YZ, or XZ view of your graphs.
Speed improvements: the implicit surface algorithm was sped up by over 90%!

Original release

Multiple graphs: graph multiple functions of various types in the same space. The 3D grapher can graph 3D functions, parametric curves (spacecurves), parametric surfaces, implicitly defined surfaces, implicit spherical surfaces, implicit cylindrical surfaces, 3D vector fields. Each graph gives control over domains and discritization (resolution).
Vector fields on surfaces: attach a vector field to a surface, to show what a vector field looks like where it crosses the surface. A vector field can be attached to any surface.
ClipBounds: set the global Bounds to clip off surfaces within a specified window. Handy for graphing functions with asymptotes, or just to cut off a paraboloid to make it look like a bowl.
Scale axes: scale the axes to the specified Bounds. Because the Grapher was designed to show multiple graphs simultaneously, the axes are not automatically adjusted to the geometry. This feature allows you to compress or stretch the graph to fit nicely in the window.
Axes: Show a boundbox with axes.
JavaView: The Grapher is built on the JavaView API. The API provides a wealth of additional features. If you right-click on the graph, you can switch from rotation mode to scaling or translation mode. For more features, choose Control Panel from the list to inspect the current geometry or adjust colors.

2D Grapher

Original release

Multiple graphs: graph multiple functions of various types in the same plane. The 2D grapher can graph 2D functions, implicit curves, parametric curves, polar curves, vector fields, and piecewise functions.
Vector fields on curves: attach a vector field to a curve, to show what a vector field looks like where it crosses the curve.
ClipBounds: set the global Bounds to clip off surfaces within a specified window. Handy for graphing functions with asymptotes, or just to cut off an exponential.
Scale axes: scale the axes to the specified Bounds. Because the Grapher was designed to show multiple graphs simultaneously, the axes are not automatically adjusted to the geometry. This feature allows you to compress or stretch the graph to fit nicely in the window.
Axes: Axes are displayed by default. An XY grid can be shown or turned off.
JavaView: The Grapher is built on the JavaView API. The API provides a wealth of additional features. If you right-click on the graph, you can switch from rotation mode to scaling or translation mode. For more features, choose Control Panel from the list to inspect the current geometry or adjust colors.

ODE Grapher

Original release

ODE types: Graph solutions to first through fourth order ODES, as well as two and three variable systems of ODEs.
Click to see: Initial conditions can be typed in, or click on the graph to set. If desired, multiple solution curves can be graphed in the same plane.
Runge-Katta: A fourth-order Runge-Katta integrator is used to produce accurate solution curves.
Multiple Graphs: Graph any combination of variables in the 2D window, including multiple graphs simultaneously (eg. x vs t and y vs t). Graph any combination of 3 variables in the 3D window.
Vector Field: when appropriate, the vector field can be displayed under the graph.
Window: Set the viewing window yourself, or have it adjust to the solution curves.
