How to run these examples

## DESCRIPTION

scat is a prefab for producing 2-D scatterplots with optional point labeling, correlation, regression line, and error bars.`` Based on proc scatterplot .``

## PARAMETERS

standard prefab parameters are all supported. data, x and y are required.``

  corr which, if `yes`, will cause correlation and regression to be computed and displayed;

  id, a data field holding a data point identifier string;

  xerr, a data field holding values for horizontal error bars;

  ptsym, ptcolor, and ptsize, which control the shape, color, radius, and fill style for the data points (see symboldetails ), default is filled blue circle of radius 0.04

  corrcolor, the color for the regression line and correlation annotation (default green)

  idcolor, the color for the id labels (default orange)

  errcolor, the color for the error bars (default gray(0.7)).``

  cats may be specified as `yes` to indicate that X data will be processed as categories rather than continuous numerics.``
