I am new to labview and I am trying to create a temperature controller. I looked over the PID temperature controller example and have most of my VI working. What I would like to do ideally is have a user input a set of arbitrary times and temperatures via a two column table. This set of data would them be interpolated and a graph created just like the simulate arbitrary signal VI does. After this data is loaded by a push button on my VI by some push button on my VI, the VI would compare the measured signal to the desired signal input by the user. If the measured temperature was less than the desired signal a boolean 1 would be output, which would turn on a heater. My two main problems are setting up a table on the front panel of my VI to accept and create the desired "temperature curve", and graphing the actual temperature on the same graph as the desired temperature(s). Currently I have the desired temperature being input in the Simulate Arbitrary Signal VI's properties, and it compares and outputs properly to the heaters. Everything works fine, but I would like to graph both data sets on the same graph. My actual measurements are single 32-bits, while my desired signal is a dynamic data set. Any help would be appreciated
Thanks-
Bill
