Pie Chart --- Optional arguments of "\psChart"

Now we come to examine the optional arguments of command "\psChart". The following table lists the special options belong to "\psChart".

name	description	default value
chartSep	distance from the pie chart center to an outraged pie piece	10pt
chartColor	gray or color	gray
usercolor	a comma separated list of user defined colors for the pie pieces encloed with { }	{ }
chartNodeI	the position of the inner node, relative to the radius	0.75
chartNodeO	the position of the outer node, relative to the radius	1.5

With these arguments we can plot a outstanding pie chart.
