OCEAN getData behavior

SharksFan

 Hi,

I have a list of signals and corresponding strip numbers that I want to plot them on in a form like:

 my_stripAssignment = list( '(v("/enable")       1)

                                              '(v("/disable")       2) )

I have a foreach loop that grabs the signals and their strip number assignment one-by-one:

foreach( signal_name my_stripAssignment

 plot( getData(car(signal_name)) ?strip cadr(signal_name) ) )

I noticed that if I query the signal_name during the loop that it no longer just returns the assigned value out of the list, but instead also has the resultsDir and result data along with it.  In other words, I expected signal_name to return v("/enable") , but instead it returns v("/enable" ?resultsDir "/home/user/CDS/OCEAN/test/psf" ?result "tran").

So it seems this change happens after I use the getData command.  Am I doing something wrong?  Is there a better approach?  Or is getData messing me up?

    Hi,

    I don't think you are doing anything wrong; I think you are right that it is getData that changes the name.  It is a pity that you cannot do this in a single call to plot, but unfortunately you need to expand the list of variables and so you cannot use the apply function to build the call to plot (in other words, you'd like to be able to do this: apply('plot `(,@listOfVariablesToPlot ?expr ,listOfNames ?strip ,listOfStripNums) - I think I've got the syntax right there, but I have not tested this, and it won't work anyway).

    I think that you just need to add the ?expr argument to the call to the plot function so that the name is as you'd like to see it, here's an example:

    
  foreach((sig num name)
                         list(v("/enable") v("/disable"))
                         list(1 2)
                         list("enable" "disable")
    plot(sig ?strip num ?expr list(name))
  )

    I have not tested this! You might need to rework it, and possibly use getData again?

    Anyway, I hope that this helps you.
