Example 8.1 - Plotting contours

In this example we will plot both types of contours for the function z=sin xy. 

Contour with option Style=Bottom

export(plot, contour):
 
justHill := contour(
   [x, y, 10*x*y*exp(-x^2-y^2)], x=-2..2, y=-2..2,
   Style = Bottom,
   LineWidth = 5,
   Contours = 20,
   Grid = [20,20],
   Colors = [Height, RGB::Blue, RGB::Red]
): 

 
plot(justHill)

Contour with option Style=Attached

justHill2 := contour(
 
[x, y, 10*x*y*exp(-x^2 - y^2)], x=-2..2, y=-2..2,
   Style = Attached,
   LineWidth = 5,
   Contours = 20,
   Colors = [Height, RGB::Blue, RGB::Red]
):

 
plot(justHill2, Scaling = UnConstrained)
