How to run these examples
DESCRIPTION
lines is a
prefab
for producing line plots with optional point symbols and error bars,
for up to four groups.
For the first group data points are in data fields given in x and y, and
optional error bar value given in err.
By default x is assumed to be continuous numeric, but it can be categories
if cats is specified (for chronological X data, use the
chron prefab
).
To display a second curve, use y2, err2, etc.
Same for third and fourth curves.
This prefab is based on
proc lineplot
.
PARAMETERS
standard prefab parameters
are all supported. data, x and y are required.
name is a short description for the first curve, for
inclusion in a legend.
linedet controls
line appearance details
for the first curve.
pointsym controls the data points on the first curve.
symbol
. It may be given as none for no point symbol.
y2, err2, name2, linedet2, and pointsym2
may be specified for a second curve. x will be used for the
X component of the curve.
y3, err3, name3, linedet3, and pointsym3
may be specified for a third curve. x will be used for the
X component of the curve.
y4, err4, name4, linedet4, and pointsym4
may be specified for a fourth curve. x will be used for the
X component of the curve.
step may be specified as yes to get stairstep curves.
This turns off point symbols.
fill may be specified as yes in order to fill the area under
the curve with a solid color. If this is used the linedet attribute(s)
should each contain a
color
cats may be specified as yes to signify that X values
are categories rather than numeric.
errcolor is the error bar
color
(default = black)
errwidth is the width of error bar tails (default = 0.08)
errthick is the thickness of the error bar lines (default = 0.5)
legend controls the
location
of the legend. Example: "legend=1 0.5" Default is min+0.4 max.
