Plots
Graphics Keywords
The IDL Direct Graphics routines, CURSOR, ERASE, PLOTS, POLYFILL, TV (and TVSCL),
TVCRS, TVRD, and XYOUTS, and the plotting procedures, AXIS, CONTOUR, PLOT, OPLOT,
SHADE_SURF, and SURFACE, accept a number of common keywords. Therefore, instead
of describing each keyword along with the description of each routine, there is
a special
man page in the idlhelp, called by searching "graphics keywords". Here
follows a brief
description of them:
BACKGROUND
Background color index when erasing.
CHANNEL
Channel index or mask for multi-channel displays.
CHARSIZE
Overall character size.
[XYZ]CHARSIZE
Character size for axes.
CHARTHICK
Overall thickness for vector fonts.
CLIP
Coordinates of clipping window.
COLOR
Color index for data, text, line, or polygon fill.
DATA
Set to plot in data coordinates.
DEVICE
Set to plot in device coordinates.
FONT
Text font index: -1 for vector, 0 for hardware fonts.
[XYZ]GRIDSTYLE
Index of linestyle to be used for tickmarks and grids.
LINESTYLE
LInestyle used to connect data points.
[XYZ]MARGIN
Margin of plot window in character units.
[XYZ]MINOR
number of minor tick marks.
NOCLIP
Set to disable clipping of plot.
NODATA
Set to plot only axes, titles, and annotation w/o data.
NOERASE
Set to inhibit erasing before new plot.
NORMAL
Set to plot in normal coordinates.
ORIENTATION
Angle (in degrees counter-clockwise) for text.
POSITION
Position of plot window.
PSYM
Use plotting symbols to plot data points.
[XYZ]RANGE
Axis range.
[XYZ]STYLE
Axis type.
SUBTITLE
String for subtitle.
SYMSIZE
Size of PSYM plotting symbols.
T3D
Set to use 3D transformation store in !P.T.
THICK
Overall line thickness.
[XYZ]THICK
Thickness of axis and tickmark lines.
[XYZ]TICKFORMAT Allows advanced
formatting of tick labels.
TICKLEN
Length of tickmarks in normal coordinates. 1.0 produces a grid. Negative values
extend outside window.
[XYZ]TICKLEN
Tickmark lengths for individual axes.
[XYZ]TICKNAME
String array of up to 30 labels for tickmark annotation.
[XYZ]TICKS
Number of major tick intervals for axes.
[XYZ]TICKV
Array of up to 30 elements for tick mark values.
[XYZ]TICK_GET
Variable in which to return values of tick marks.
TITLE
String for plot title.
[XYZ]TITLE
String for specified axis title.
ZVALUE
The Z coordinate for a 2D plot in 3D space.
Z
Z coordinate if Z argument not specified in 3D plot call.
