## 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`.``
