Measures not Available in Dynamic Frequency Analysis Results Window Definition

I am attempting to run a dynamic frequency analysis on a vertical bottle. I define everything, in that the modal and static give good results. I am a little hesitant on how exactly the DFA works (as far as what the inputs are, I've done this in other software), but that is not really the question here, as I am sure I can figure it out once I start seeing results.

After my DFA completes, I go to display results and the options available to me are very limited. It must be a graph and ordinate must be a measure (with abcissa freq/measure). The problem is, even though there are predefined measures, and I have defined measure that are compatible with DFA and DTA, there are ZERO measures available to choose from. Where are the measures? Searching for answers is difficult as I am always directed to rants about the measurement tool.

I also found that this was a problem, with apparently not solution in Wildfire?

In a dynamic frequency analysis, there are not defult measures initially defined. If you do create measures and want to plot them against frequency, then you need to make sure that you've selected "At Each Step" under the "Dynamic Evaluation" section of the measure definition window.

Thanks Shaun,

It was indeed the 'at each step' that needed to be checked. At least I can get results now. Now I am just having trouble finding comprehensive instruction to explain all the different parameters...

Any one in particular you'd like explanation on?
