plot_nao
plot_nao, which can represent it by:
The right mouse button displays a menu. The left mouse button saves (x,y,z) values (z-images only) which can be written to a file.
The Tcl code is in the files plot_nao.tcl and plot_nao_procs.tcl.
plot_nao expression ?options?
-barwidth float: (bar chart only) width of bars in x-coordinate units

matrix with 3 or 4 columns & up to 256 rows. If there are 4 columns then the
first gives color indices in range 0 to 255. Values can be whole numbers in
range 0 to 255 or fractional values from 0.0 to 1.0.
""

env(PRINTER)
if defined, else any printer)
-range expression: defines scaling (Default: auto scaling)
-rank 1, 2 or 3: rank of sub-arrays to be displayed (Default:
3 <<< rank(data)
)
-scaling 0 or 1: 0 = Start with scaling widget hidden. (Default: 1)
-symbols list: Symbol drawn at each point of xy-graph.
Can be
plus, square, circle, cross, splus, scross, triangle
or single character (e.g.
"*"
) (Default:
""
i.e. none)
-title string: title (Default: NAO label (if any) else expression)
-type string plot-type (
"bar", "tile", "xy" or "z"
)
If rank is 1 then default type is
"xy"
If rank is 2 and n_rows <= 8 then default type is
"xy"
If rank is 2 and n_rows > 8 then default type is
"z"
If rank is 3 then default type is
"z"
-width int: Desired width (screen units). Not used for tiled-plot.
Type xy/bar: Width of whole window (Default: automatic)
