Set 3D Maple plot options

• ambientlight=[r, g, b]

Sets the red, green, and blue intensity of the ambient light for user-defined lighting.

r, g, and b values must be numeric in the range 0 to 1.

• axes=f

Specifies the type of axes.

Choose from: boxed, frame, none, or normal.

• axesfont=l

Font for the labels on the tick marks of the axes (specified in the same manner as font).

Overrides values specified for font.

• axis=t or axis[dir]=t

Specifies information about the x -axis, y-axis, and z-axis.

axis=t applies the information given in t to all 3 axes.

axis[dir]=t allows the information to be specified for a single axis or 2 axes, with dir taking the value 1 ( x -axis), 2 ( y -axis), and 3 (z-axis), or a sequence of 2 of these values.

• caption=c

The caption for the plot.

The value of c must be a string or a list consisting of the caption followed by the captionfont option.

TIP: You can create multi-line captions for standard plots. Use the characters \n to start a new caption line.

TIP: Check out Maple^TM Online Help for more information on caption.

• captionfont=l

Specifies the font for a plot caption (specified in the same manner as font).

Overrides values specified for font.

• color=c or colour=c

Specifies the color of the plot.

c should be spelled without capital letters. Example — blue, not Blue.

NOTE: Color specification takes precedence over shading specification, regardless of the order of the options in the command.

TIP: Check out Maple^TM Online Help for more information on color.

• contours=n

Specifies the number of contours or a list of contour values.

n is a positive integer or a list of contour values.

• coords=c

The coordinate system.

The value c is a choice from the list of coords.

TIP: Check out Maple^TM Online Help for more information on coords.

• filled=true/false or list

If set to true, the area between the surface and the x-y plane is given a solid color.

The value of the filled option can also be a list containing 1 or more sub-options (color, style, or transparency).

The options in the list are applied only to the filled area, and not to the original surface itself.

NOTE: This option doesn't work with non-Cartesian coordinate systems.

• filledregions=true/false

If set to true, the regions defined by the curves on a surface are filled with different colors.

Only valid with the following commands: contourplot3d, listcontplot3d, and plot3d with the style=contour option.

NOTE: This option doesn't work with non-Cartesian coordinate systems.

• font=l

Defines the font for the plot title, caption, axis tickmark labels, and axis labels if no values have been specified for the axesfont, captionfont, labelfont, or titlefont options.

The value l is a list of the form [family, style, size].

The value of family can be: Times, Courier, Helvetica, or Symbol.

TIP: family can also be any font name supported by your system. Example — Tahoma and Lucida in Windows.

NOTE: The first letter of the family value must be capitalized.

style can be omitted or can be: roman, bold, italic, bolditalic, oblique, or boldoblique.

NOTE: The Symbol family doesn't accept a style option.

size is the point size to be used.

• glossiness=g

Specifies the glossiness of a plotted surface.

g controls the amount of light reflected from the surface and must evaluate to a floating-point number in the range 0 to 1.

A g value of 0 results in no light reflected, giving the surface a matte or dull finish.

A g value of 1 results in maximum reflection, giving a glossy finish.

• grid=[m,n]

Specifies the dimensions of a rectangular grid on which the points are generated (equally spaced).

NOTE: The value of the grid option may affect the look of the surface wireframe. For more information, see the note under the style option below.

NOTE: The surface is rendered using the specified grid option and can affect the look of the surface of the wireframe. When the style option is set to surfacewireframe, a wireframe corresponding to the grid is drawn. Some gridlines may be omitted to avoid a very dense wireframe.

• gridstyle=x

Specifies the grid shape.

x can be: rectangular or triangular.

NOTE: This option is not available for all 3-D plot objects. Example — gridstyle has no effect on polyhedra created with the plots[polyhedraplot] command or with the plot3d command combined with the filled=true option.

• labeldirections=[x, y, z]

Specifies the direction in which labels are printed along the axes.

The values of x, y, and z must be horizontal or vertical.

NOTE:  The axes option must be set to boxed, frame, or normal.

• labelfont=l

Font for the labels on the axes of the plot (specified in the same manner as font).

Overrides values specified for font.

• labels=[x, y, z]

Specifies labels for the axes.

If labels aren't specified and there aren't available variable names in the plotted function, no labels are applied.

x, y, and z must be a string.

• light=[phi, theta, r, g, b]

Adds a directed light source from the direction of phi, theta in spherical coordinates.

Red, green, and blue intensities are given by r, g, and b.

r, g, and b must be numeric in the range 0 to 1.

• lightmodel=x

Selects a predefined light model to illuminate the plot.

Valid light models: none, light1, light2, light3, and light4.

NOTE: The value x must be in lowercase.

• linestyle=t

Controls the line style of curves.

t can be an integer from 1 to 7, where each integer represents a line style, as given in the order of: (1) solid, (2) dot, (3) dash, (4) dashdot, (5) longdash, (6) spacedash, or (7) spacedot.

t can also be the name of an available line styles. Example — dash

• numpoints=n

Specifies the minimum number of points to be generated for a curve or a surface.

NOTE: If numpoints=n option is defined, then the plot3d command uses a rectangular grid of dimension isqrt(n+3)+1. Otherwise, the plot3d command uses the default value for the grid option.

• orientation=[theta, phi, psi]

Orientation is specified by angles in degrees.

psi defines the plot rotation about the x-axis.

phi defines the plot rotation (transformation) about the y-axis.

theta defines the plot rotation (transformation) about the z-axis.

These angles are the Euler angles for the transformation matrix, using the axes specified.

The angle psi is optional and is assumed to be 0 if not given.

• projection=r

Specifies the perspective from which the surface is viewed.

r is a real number between 0 and 1.

1 results in orthogonal projection.

0 results in wide-angle perspective rendering.

r can also be: fisheye(0), normal(0.5), or orthogonal(1).

• scaling=s

Specifies the scaling of the graph.

The constrained value causes all axes to use the same scale. Example — A sphere appears perfectly round.

• shading=s

Specifies how the surface is colored.

s can be: xy, xyz, z, zgrayscale, zhue, or none.

NOTE: The color option takes precedence over the shading option, regardless of the order of the options in the command.

• size=[w,h]

Specifies the size of the plot window.

You can set the size of the plot window by specifying the number of pixels, a proportion of worksheet width, a ratio (Example — a square), the golden ratio, or a custom ratio.

w (width) must be a positive numeric value or the string default.

h (height) must be a positive numeric value, or: default, golden, or square.

If w or h is a number greater than or equal to 10, it specifies the number of pixels for the width or height.

If w or h is default, then the default size (which may be interface-specific) is used.

If w is a number less than 10, then the plot window width is w multiplied by the width of the worksheet.

NOTE: This form for w is ignored if the plot is part of a plot array.

If h is a number less than 10, then the height is h multiplied by the width of the plot window as given by w.

If h is square, then this is equivalent to h having the value 1.0.

If h is golden, then this is equivalent to h having the value equal to the reciprocal of the golden ratio ( 1/2 + sqrt(5)/2 ).

• style=s

The plot style can be: surface (patchnogrid), surfacewireframe (patch), contour, surfacecontour (patchcontour), wireframe (line), wireframeopaque (hidden), point, or pointline.

surface results in a colored surface patch rendering.

wireframe produce a wireframe.

contour produce contour lines.

wireframeopaque produces a wireframe over an opaque surface.

point results in a plot of the sample points only.

NOTE: The surface is rendered using the specified grid option. When the style option is set to surfacewireframe, a wireframe corresponding to the grid is drawn. Some gridlines may be omitted to avoid a very dense wireframe.

• symbol=s

Specifies the symbol to use for plotted points.

Choose from: asterisk, box, circle, cross, diagonalcross, diamond, point, solidsphere, or sphere.

• symbolsize=n

The size (in points) of a symbol used in plotting can be given by a positive integer.

NOTE: This doesn't affect symbol=point.

• thickness=n

Specifies the thickness of lines in the plot.

n must be a non-negative number.

A value of 0 produces the thinnest line that looks good in most contexts.

• tickmarks=[m, n, p]

m, n, and z specify the tickmark placement for the x-axis, y-axis, and z-axis, respectively.

Choose from: an integer specifying the number of tickmarks, a list of values specifying locations, a list of equations each having the form location=label, a name, or a spacing structure.

For greater control over the appearance of tickmarks, use the axis option.

If the axis option is also provided and contains a tickmarks sub-option, then that option overrides this tickmarks option.

TIP: Check out Maple^TM Online Help for more information on tickmarks.

• title=t

The title for the plot.

t must be a string or a list consisting of the title followed by the font option.

TIP: You can create multi-line titles for standard plots. Use the characters \n to start a new title line.

TIP: Check out Maple^TM Online Help for more information on title.

• titlefont=l

Font for the title of the plot (specified in the same manner as font).

Overrides values specified for font.

• transparency=t

Specifies the transparency of the plot surface.

t must evaluate to a floating-point number in the range 0 to 1.

A value of 0 means opaque.

A value of 1 means fully transparent.

• view=zmin..zmax or [xmin..xmax, ymin..ymax, zmin..zmax]

Indicates the minimum and maximum coordinates of the surface to be displayed on the screen.
