Time chat/value converting problem

[atanupanda]

Hi

 

I am very new in iReport. i have learnt a lot from this forum.

Now I am trying to draw time series chart.

In my data base I have last_computed_time (String) ex=12:30 am Jan 2nd, 07, and time_interval as String and five values like t1(double),t2(double),t3(double),t4(double),t5(double).

 

Now I have to draw a time series chart where

 

value time

----- --------

t1 last_computed_time + time _interval

t2 last_computed_time + time _interval+ time _interval

 

t3 last_computed_time + time _interval+ time _interval+ time _interval

 

in this up to t5.

my problem is that I can't convert the string value of last_computed_time and time _interval

 

and also addition of both of them.

Actually in java I can convert it using SimpleDateFormat and parsing method. but in ireport I am getting problem .

I need some thing like this

 

Please help me.

Any help would be greatly appreciated.

Thanks in advance.
