[zhrizvi]

Dear all
Good day,
Need some guidance on General Graph presentation in Cacti. As per our observation if we scale down to hour/half hour Graph presentation go like in jumps in graph however from PRTG same node graph with same granulairty is populating fine like a straight line but cacti always show jumps in plotting. Please guide.
