 listcontplot
 two-dimensional contour plot of a grid of values

 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

 > $\mathrm{with}\left(\mathrm{plots}\right):$
 > $\mathrm{listcontplot}\left(\left[\mathrm{seq}\left(\left[\mathrm{seq}\left(\mathrm{sin}\left(\frac{xy}{5\cdot 5}\right),x=-15..15\right)\right],y=-15..15\right)\right]\right)$
 > $\mathrm{listcontplot}\left(\mathrm{Matrix}\left(\left[\mathrm{seq}\left(\left[\mathrm{seq}\left(\mathrm{sin}\left(\frac{\left(i-15\right)\left(j-10\right)}{\mathrm{Pi}\cdot 20}\right),i=1..30\right)\right],j=1..20\right)\right]\right)\right)$
 > $\mathrm{listcontplot}\left(\left[\mathrm{seq}\left(\left[\mathrm{seq}\left(\mathrm{sin}\left(\frac{\left(i-15\right)\left(j-10\right)}{\mathrm{Pi}\cdot 20}\right),i=1..30\right)\right],j=1..20\right)\right],\mathrm{filledregions}=\mathrm{true}\right)$

Compatibility

 • The G parameter was updated in Maple 15.
