We need to know more about MonthlyRain and RainData. If MonthlyRain(RainData) is producing a scalar, you would get the problem.

if i change bulanan file with ;

 mr = MonthlyRain( RainData );      
   bar( mr(1).Rain );
       ylabel('Akumulasi Curah Hujan (mm)')
       xlabel('Bulan')

=== no error but pushbutton process wrong data, the pushbutton result is bar mr(2) (not bar mr(1))

or, if i change with;

 mr = MonthlyRain( RainData );      
   bar( mr(2).Rain );
       ylabel('Akumulasi Curah Hujan (mm)')
       xlabel('Bulan')

=== error with msg ;

Index exceeds matrix dimensions.

I have not checked your data file, but it appears your data file only has information for a single year. Your rain_data structure will only have as many array members as there are distinct years in your data.

i have 2 year data.. in a folder:

bar( mr(1).Rain ); %2010 data
bar( mr(2).Rain ); %2011 data

[Soni huu]

thanks, in my folder just single year, that wrong folder..
