<p class="MsoNormal"><span style="color:#1F497D">I don’t think Plot Global Variables Over Time works the way you think it does. This filter assumes that the global arrays contain a static array the same size as the number of time steps and then plots that with
the time array on the x axis and the entries in this array in the y axis. If the size of the global variable does not equal the number of time steps, the view will show nothing.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">I think you really want to use Plot Selection Over Time. That you can give a value and it will iterate the pipeline over time and compute the value for each time step. Unfortunately, it looks like the filter
is broken for selections on field data. It works, however, on table data, so you can write the result as that.<o:p></o:p></span></p>

<p class="MsoPlainText">How do you "see" FieldData variables created in the ProgrammableFilter in the PlotGlobalVariablesOverTime filter? I'm creating a FieldData variable in the ProgrammableFilter. Now I'd like to plot it over time. It isn't available as
an option for me to plot, though. I see other global variables, just not this one.<o:p></o:p></p>
