two-dimensional contour plot of a grid of values
list of lists or Matrix of numeric values
The listcontplot function creates a 2-D contour plot of a grid (list of lists or Matrix) of numeric values.
Remaining arguments are interpreted as plot options. See plot[options] for a list of possible options.
Option levels is provided as a synonym of the option contours. Either of these specifies the number of contours to draw, the default being eight.
The filledregions=true option can be specified to obtain a filled contour plot. The coloring option can, in this case, be used to specify a gradation in color, or color range. The default is a color range from red to yellow. To specify a color range, use the form coloring=[a,b], where a and b refer to colors recognized by plot. See plot[color] for an explanation of colors.
Data saved in external files may be imported into a Matrix with the ImportMatrix command and passed to listcontplot.
Note that the plot grid does not correspond exactly in orientation with the display of the list or Matrix data as it is printed in Maple. Instead, the i-th sublist or row of the Matrix corresponds to data values with x-coordinate equal to i.
The G parameter was updated in Maple 15.
