Guna package java.awt.geom.* untuk draw 2D lines and objects. Tgk di sini:

dalam banyak2 classes tu, mayb ko nak tgk Line2D, Point2D. Try lukis satu rectangle guna satu lagi class Rectangle2D.

disebabkan ko pki applet, aku assume ko nk buat web..

so, kalo nk bt graf, aku bg suggestion pki javascript

thanx...really cool website...

after keep searching...aku jumpa site ni..

http://java.sun.com/docs/books/tutorial/2d/index.html

tapi x jumpa la dia nye kod utk wat graf2 pie etc2 mcm dlm gambar tu...mmm camne nak wat btk camgitu...ade sampel kod x? klu bleh ade input dia...berapa data yg nk masuk etc2

[unexistance 3]

aku suggest jFreeChart

http://www.jfree.org/jfreechart/

ni akan simplify ko nyer development (xyh hand-code Graphics etc..)

thanx...aku tau yg ni...tapi yg ni xde input output..

mmg ade byk graf....tapi camne klu aku nk masukkan certain data..pas tu jadila graf

Aku pun tak pernah code complex graphs, but suppose the idea is, buat class untuk ambil input dari user (untuk dijadikan koordinat x,y ) and then store semua input dalam variables and then pass to the respective classes in the packages.

ok cmni la, ko install tomcat dl..

pstu, ko dload jfreechart + cewolf

nnt dlm cewolf nyer folder ada .war file

copy paste msuk tomcat, run

ctu ada demo

alternatif ln, pki javascript tuh (aku ada bt utk klien )

p/s: mmg jfreechart dbuat utk input output le, kalo x wtpe die bt package tuh
