Drawing 3d graph from array table

[Mekonom]

Hi all. I have an table like [][]tablo and it includes 3 value x,y,z . and there is about 600 lines . How can I draw a table from this values? I saw on that on java has 2d graph with x,y but how can i draw 3d? x,y,z ?

0.0000 0.0000 55.0000
208.9600 -99.9630 55.0000
208.9600 -99.9630 14.0520
208.9600 -100.3960 13.6300
208.9600 -100.8530 13.2350
208.9600 -101.3330 12.8690
208.9600 -101.8350 12.5320

this is out put of table .

Hi again .I thought that 3D graph will be hard and decided to make it 2D .But there is only 1 problem ..I have 2 class and I must take tablo[][] from second class to Grap class .here codes

thanks for replay.It solved my problem :)
