#
# About:
#
# The following PHP3 code provides a nice class interface for
# html graphs. It provides a single, reasonably consistent
# interface for creating HTML based graphs. The idea behind
# this code is that the user of the class sets up four or five
# arrays and pass these to html_graph() which then takes
# care of all the messy HTML layout. I am reasonably happy
# with the outcome of this interface. The HTML that must be
# generated for HTML graphs *is* messy, and the interface is
# very clean and flexible. I think that once you generate
# one graph with it, you’ll never look at creating HTML graphs
# the same. The arrays that must be set up consist of:
#
# * A names array containing column/row identifiers ($names)
# * One or two values arrays containg corresponding
# values to the column/row names ($values & $dvalues)
# * One or two bars array which also corresponds to the names
# array. The values in these arrays are URLS to graphics
# or color codes starting with a # which will be used to
# generate the graph bar. Color codes and graphics may
# be mixed in the same chart, although color codes can’t
# be used on Vertical charts. ($bars & $dbars)
# * The heart of customization… a vals array. If this
# array isn’t created then html_graphs will use all
# default values for the chart. Items that are customizable
# include font styles & colors, backgrounds, graphics,
# labels, cellspacing, cellpadding, borders, anotations
# and scaling factor. ($vals)
#
#######################################################################
# Known Bugs:
# * Currently the $vals[background] tag element doesn’t
# work in Netscape.
#######################################################################
# To Do:
#
# * Would like to make the $vals array to html_graph() completely
# optional. Currently it has to at least be an empty array.
