Detailed Description

Draws the horizontal lines of a grid over a specified region
using the standard tick specification (see help(Ticks)) to place the
grid lines.

HGrid(xmin, xmax, low, high, ticks, miniticks, logbase, mini_attr, attribute=value)

xmin, xmax              required        the x range
low, high               required        the y range
ticks                   default=-10     request ticks according to the standard
                                        tick specification (see help(Ticks))
miniticks               default=False   request miniticks according to the
                                        standard minitick specification
logbase                 default=None    if a number, the axis is logarithmic
                                        with ticks at the given base (usually 10)
mini_attr               default={}      SVG attributes for the minitick-lines
                                        (if miniticks != False)
attribute=value pairs   keyword list    SVG attributes for the major tick lines
