public JCFillStyle(Color c,
                   int p)

Constructor for fill style objects.

Parameters:

c - fill color

p - fill pattern. One of NONE, SOLID, PER_25, PER_50, PER_75, HORIZ_STRIPE, VERT_STRIPE, STRIPE_45, STRIPE_135, DIAG_HATCHED, or CROSS_HATCHED.

Creates a default fill style.

Parameters:

c - JCChart instance

Returns:

JCFillStyle object with default color and fill pattern. The defaults are cycled, so consecutive calls will return different fill styles.
