[rrd-users] rrd graph problem - flat areas only visible, no skew areas

[Monjurul Hasan]

Hi,
        
        I have tried this php code to create rrd graph from mrtg rrd
        file(which is created from log file by mrtg itself).I have found
        the weekly graph but there is only flat areas,no skew part is
        there(no curved part is present which is present in original
        graph) .
         
        My daily graph shows blank.I think that this is for same
        prblem ,
        because in original graph there is only skewed curve areas.
        
        anyone has idea about it? Please help me.
        
         
        Thanks,
        hasan
