How can I update the table when new values come

Hello all!

 

I am new to Labview and I need your help! I currently meet two problems in Labview.

1. The first problem is the table. I use 'build table' vi. in my system and I have a excel table in the front panel. This table is to show the data I measured. However, it seems the table is updating according to the current time. But what I really want is that the table only records the new values. How can I do with that?

 

2. I have two measurement values from two channels. I will use this two values to do some calculation. For the calculation, I employ a simple Formula node. The problem I am facing to is that the result value will change when anyone of  input values changes. How can I do if the operation can wait until the two input values change?

 

Thank you very much

 

Best Regards

Daisy
