Graphics

The following directives produce the plots in “line-printer” style, i.e. using the characters of ordinary textual output:

`LPCONTOUR`	produces contour maps of two-way arrays of numbers
`LPGRAPH`	produces scatter plots and line graphs
`LPHISTOGRAM`	plots histograms

Genstat can also produce high-resolution plots. The relevant directives have two main purposes. There are those that define the “graphics environment” for subsequent plots, and those that do the plotting. Often the default environment, set up at the start of a program, will be satisfactory. To change the graphics environment, the following directives can be used:

`XAXIS`	defines the x-axis in each graphical window
`YAXIS`	defines the y-axis in each graphical window
`ZAXIS`	defines the z-axis in each graphical window
`AXIS`	defines an oblique axis for high-resolution graphics
`DEVICE`	switches between graphics devices
`FRAME`	defines the positions of the windows within the frame
`PEN`	defines the properties of the graphics “pens”
`DFONT`	defines the default font for high-resolution graphics
`DKEEP`	saves information about the graphics environment in Genstat data structures
`DLOAD`	loads the graphics environment settings from an external file
`DSAVE`	saves the current graphics environment settings to an external file
`GETRGB`	provides a standard sequence of colours (defined by the initial defaults of the Genstat pens)

The directives for plotting high-resolution graphs are:

`BARCHART`	plots bar charts
`DGRAPH`	produces scatter plots and line graphs
`DHISTOGRAM`	plots histograms
`DPIE`	produces pie charts
`DCONTOUR`	produces contour maps

`DSHADE`	produces a shade diagram of 3-dimensional data
`DSURFACE`	draws a perspective plot of a two-way array of numbers
`D3GRAPH`	plots a 3-dimensional graph
`D3HISTOGRAM`	produces 3-dimensional histograms
`DSTART`	starts a sequence of related plots
`DFINISH`	ends a sequence of related plots
`DDISPLAY`	redraws the current graphical display
`DCLEAR`	clears a graphics screen
