Edit and Contour Plot 2-D Functions
This plot demonstrates the use of the ParseFunction class from
the Graph 2D Java plotting package.
A 2-D function is parsed and the result plotted using the Contour
class in the Graph 2D Java plotting package. You can edit the function
in the window to any valid function of
x and y, and after clicking on the PlotIt! button, the applet will
update the contour
display and the label on the ordinate axis. You can also change the displayed
contour plot parameters and update the plot.
