I´m trying know how to lookup a specific value from a matrix/table according to a pressure and temperature values in PI System Explorer; for example:

 

 

Temperature (°C)20 kg/cm2g21 kg/cm2g
150.280.4
200.30.5
300.50.7

 

    

15,00
16,34
17,68

Pressure and Temperature Data are obtained from specific instruments from the Plant (For Example PI-315 and TI-385). If there is a pressure around 20 kg/cm2g and temperature is aprox. 20°C, the value that will be displayed is 0.3.

 

Thanks in advance
