/I/J/K/L/M/N /X/Y/Z/T/E/F /D /FRAME /NOLABEL /OVERLAY/SET_UP /TITLE /TRANSPOSE /VIEWPOINT /ZLIMITS /ZSCALE
Produces a wire frame representation of a two-dimensional field.
yes? WIRE[/qualifiers] expression
The expression may be anything described in the chapter "Variables and Expressions", section "Expressions"The expression will be inferred from the current context if omitted from the command line. Multiple expressions are not permitted in a single WIRE command. The indicated region should denote a plane (2D) of data.
Command qualifiers for WIRE:
Specifies value or range of axis subscripts (I, J, K, L, M, or N), or axis coordinates (X, Y, Z, T, E, or F) to be used when evaluating the expression being plotted.
The following commands will create a wire frame representation of a simple mathematical function in two dimensions.
yes? SET REGION/I=1:80/J=1:80
yes? WIRE/VIEWPOINT=-4,-10,2 exp(-1*(((I-40)/20)^2 + ((J-40)/20)^2) )
Causes the graphic image produced to be captured as an animation frame in the file specified by SET MOVIE. (note that HDF movies are discontinued with Ferret V6.6). In general the FRAME command is more flexible and we recommend its use rather than this qualifier.
Performs all the internal preparations required by program Ferret for wire frame graphics but does not actually render output. The command PPL can then be used to make changes to the plot prior to producing output with the PPL WIRE command. This permits plot customizations that are not possible with Ferret command qualifiers. See the chapter "Customizing Plots".
yes? WIRE/VIEWPOINT=x,y,z expression
The x,y values are specified as coordinates on the X and Y axes (though they may exceed the axis limits). The z value is in units of the requested variable.
yes? WIRE/ZLIMITS=zmin,zmax,delta expression
The values given are in units of the requested variable. (The string given as an argument to /ZLIMITS= is passed unmodified to the PPLUS command WIRE as the zmin and zmax parameters.)
yes? WIRE/ZSCALE=s expression
The default value is equivalent to (ymax-ymin)/(zmax-zmin) (i.e., the aspect ratio of the Z axis to the Y axis). This qualifier is identical to the PPLUS VIEW command parameter of the same name.
