7.5. - pb, zb draw error bars
puts error bars on the plot.
pb or zbNo parameters are used. If you intend to use error bars with a particular set of data, be sure the error-bar mode is on when you read in the data from a file.
The vertical width of the top and bottom horizontal segments of the y and z error bars is taken from the symbol width set using the
cs command.
The height of the vertical segments of
the
x
error bars in 2D mode is taken from the symbol height
set using the
cs command.
If the symbol height or width is larger
than the error bar, no error bar will be drawn, unless the current
symbol type is symbol 9, a dot, in which case the symbol size is ignored.
If data is being obtained using
d 11,
gd 12
or
gd 14
to read files of indefinite length, the entire data file will be read
automatically in sections as large as the program can hold at one
time and the error bars plotted.
