Wincc Explorer 7.5 Trend and ruler controller functions

[tunc]

Hello,
I need technical support with the WinCC Explorer 7.5.0.0 program I'm using for a project.
I'm performing an integral on a trend chart using a ruler controller object.
This integral value is calculated in seconds(i need hour), and the correct result is obtained by dividing the integral value by 3600.
However, I haven't been able to divide this integral by 3600 in WinCC, neither through scripting nor any other method.
How can I do this? My goal is to see the total of the values from the flow sensor between specific dates.
This operation is performed by performing an integral in the trend window, but since I can't divide by 3600, I can't get the result I want.
I don't want to change the sample time in the archive tags. If there's a solution, I'd like your help.
