Maximum values between a range and counting

Hi,

we are currently evaluating FlexPro 9.1 and try to solve the following task.

We imported the attached file into FlexPro and want to check
if the dataset named “T_MWE_2” lies within the range of 820°C – 860°C,
and if so, get the maximum value and then finally count how often we got a hit.

I also attached an example graph to make it more clear.
