Detailed Description

Draws y error bars at a set of points. This is usually used
before (under) a set of Dots at the same points.

YErrorBars(d, attribute=value)

d                       required        list of (x,y,yerr...) points
attribute=value pairs   keyword list    SVG attributes

If points in d have

    * 3 elements, the third is the symmetric error bar
    * 4 elements, the third and fourth are the asymmetric lower and
      upper error bar. The third element should be negative,
      e.g. (5, 5, -1, 2) is a bar from 4 to 7.
    * more than 4, a tick mark is placed at each value. This lets
      you nest errors from different sources, correlated and
      uncorrelated, statistical and systematic, etc.
