Customizing FAZ dataset(IPS total sum number by date)

Dear all,

Customers request many kind of Reports on their own needs, but it's not easy for me to make them for I do not know much about DB queries..

What I need is a Bar graph of IPS totalnum by date.

I looked at predefined dataset "threat-Intrusion-Timeline", but it shows not by date, so I do not know how to change it to accumulated number to a date.

Anybody can help me on this?

Thanks!
