Two-Dimensional Plots

There are several types of two-dimensional plots in Maple. They provide for the plotting of the graph of a function of one variable, of a data set, of a parametrically defined curve, and of an implicitly defined curve. Here are the most frequently used two-dimensional plotting commands.

plot

• To plot the graph of a function of one variable in the plane, use:

          plot(f(x),x=a..b);

• To plot the graphs of several functions of one variable on the same coordinate axes use:

          plot({f(x),g(x),...,h(x)},x=a..b);

  Notice that the functions are separated by commas and the list is enclosed in braces.
• To plot a curve defined parametrically by (f(t),g(t)), use:

          plot([f(t),g(t),t=a..b]);

• To plot a data set of form use:

          plot([[x1,y1],[x2,y2],...,[xn,yn]],x=a..b);

  Notice that the coordinates of the n points are enclosed in square brackets and the list of points is enclosed in square brackets.

implicitplot

If a curve is defined implicitly by g(x,y) = h(x,y) (h could be a constant), that is, the curve is the set of points (x,y) in the domain that satisfy this equation, use:

        implicitplot(g(x,y) = h(x,y), x=a..b,y=c..d);

Note that this command is in the package plots.
