Note: See also the Toggle() command for changing plot parameters
Shows the current values of any settings which may be changed using the Alter() command.
This command alters the bin grouping value used by the Display() command when displaying a histogram or bin-mode workspace. Note, the effect is simulated for ease of use when the user is plotting a point-mode workspace.
When the bin grouping value is set to a value greater than one, the display command groups the data by averaging the values of n-bin groups starting from the first bin in the histogram. This averaging can be viewed as a rudimentary form of smoothing the data which is done on the fly, each time the display command is used. It is possible to apply the same operation to a standard workspace permanently, see the Groupbins() command for more information.
P1 (Integer)
Number of bins to group together, no grouping occurs if this value is set to 1.
This command changes the device to which the output of the display command will be sent.
P1 (String)
This is the name of the supported graphics device to which to set the display. Following the Alter/Device command all high level graphics commands will use the selected device.
This command changes the default font used by the Display() command. This will change the font for all the text used in the display.
P1 (Font)
This is the name of a supported font to which to set the display. After an Alter/Font command all high level graphics commands will use new font..
This command changes the default hardcopy device to which the output of display command is sent when a Hardcopy() command is issued.
P1 (String)
This is the name of the supported graphics device to which to set the hardcopy device will save the plot.
This command changes the default colour the Display() and command uses for drawing the axes and surrounding boxes.
P1 (Colour)
This is a colour variable returned by one of the colour functions or listed as one of the supported colours.
This command changes the default line type the Display() and Plot() commands use for drawing line plots. Useful for separating plots on monochrome terminals.
P1 (LineStyle)
This is a line style listed as one of the supported linestyles.
This command changes the default line width used by the Display() and Plot() commands use for drawing line plots.
P1 (Real)
This is a real multiplier for the default line plot width of 1 unit. The width of the line may vary on different graphics devices.
This command changes the default marker used on a Marker plot.
P1 (Marker)
This is one of the available markers listed as one of the supported markers.
This command changes the default marker size used by the Display() and Plot() commands use for drawing marker plots.
P1 (Real)
This is a real multiplier for the default marker size of 1 unit. The size of the marker may vary on different graphics devices.
This command changes the area of the display device which will be taken up by a Display() or Plot() command. The limits of the box are specified in device co-ordinates in the range 0.0-1.0 where the the values (0.0, 0.0) and (1.0, 1.0) represent the largest square available on the plotting device. It may be possible to draw slightly outside this area for devices with rectangular aspect ratios.
Xmin (Real), Xmax=(Real), Ymin=(Real), Ymax=(Real)
Normalised device co-ordinate values in the range 0.0 to 1.0. Xmin < Xmax, Ymin < Ymax.
This command changes the default colour the Display() command uses for drawing the data plot (line, histogram or markers or errors).
P1 (Colour)
This is a colour variable returned by one of the colour functions or listed as one of the supported colours.
Changes the size of the display device by a scaling factor. 1.0 is the default scaling factor.
P1 (Real)
Multiplier for the display device size.
This command changes the default text height used by the Display() and Plot() commands.
P1 (Real)
This specifies the text height as a multiplier of 100th of the height of the display. The default text height is 3.0 or 3 hundredths of the display height.
This command changes the default colour the Display() command uses for drawing text.
P1 (Colour)
This is a colour variable returned by one of the colour functions or listed as one of the supported colours.
