Calling Sequence

listcontplot(G, options)

Parameters

G

-

list of lists or Matrix of numeric values

Description

• 

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.

Examples

listcontplotMatrixseqseqsini15j10π20,i=1..30,j=1..20

listcontplotseqseqsini15j10π20,i=1..30,j=1..20,filledregions=true

Compatibility

• 

The G parameter was updated in Maple 15.
