lines prefab

EXAMPLE 1

   pl -prefab lines  data=data17  x=1 y=2  pointsym=none

   The data17 file:
	331 75
	331.624 83.5518
	332.105 88.7758
	..etc.

EXAMPLE 2

   pl  -prefab lines data=data10 delim=tab  x=1  y=2  y2=4  step=yes \
     yrange=0 name="Group A" name2="Group B" xlbl=Months

EXAMPLE 3

   pl  -prefab lines  data=data10 delim=tab  x=1  y=2 err=3  y2=4 err2=5  \
       y3=6 err3=7  y4=8 err4=9   yrange=0  xlbl=Months \
       name="Group A" name2="Group B" name3="Group C" name4="Group D" 

   The data10 file:
       0	100	2	100	4	100	3	100	4
       1.5	92	4	94	7	87	6	86	5
       3	89	4	92	8	78	6	74	4
       6	86	5	91	8	65	8	61	6
       ..etc.

EXAMPLE 4

   pl -prefab lines  data=data20  x=1  y=2 

   The data20 file:
      1031 20.96 6.4
      1032 19.71 5.8
      1033 19.98 5.9
      ... etc.

EXAMPLE 5

  pl -prefab lines  data=data20  x=1  y=2  fill=redorange pointsym=none  \
	y2=2 pointsym2=none

In this example the same data field was given twice, first to do the filled area, and again to do the blue line.

EXAMPLE 6

   pl -prefab lines  data=data20  x=1  y=2  gapmissing=yes

EXAMPLE 7

   pl -prefab lines  data=data20  x=1  y=2  fill=tan1  pointsym=none  \
	y2=2 pointsym2=none  y3=3  pointsym3=none  linedet3=color=black \
	yrange="0 25"  name="background" name3="interior"

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. If your data contains a field name header and header=yes is specified, name defaults to the y field name (new in 2.04).
: 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.
: fill may be specified as a color and causes the area under the curve to be filled.
: y2, err2, name2, linedet2, pointsym2, and fill2 may be specified for a second curve. x will be used for the X component of the curve.
: y3, err3, name3, linedet3, pointsym3, and fill3 may be specified for a third curve. x will be used for the X component of the curve.
: y4, err4, name4, linedet4, pointsym4, and fill4 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. Applies to all curves.
: gapmissing may be specified as yes or small. If yes, missing data will cause a gap in the line (normally the line connects plottable points without a gap). small is the same as yes except that it leaves a small overhang. Applies to all curves.
: 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.
