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.
