<div dir="ltr"><div><div><div>Hi Paul,<br><br></div>I think because of the bug you'll need to cobble together the Python script you want. First you can try doing everything in the GUI and recording it in a single trace and see if manually adding in the:<br><span class="im">selection = SelectCells(query="id==0")<br>ec = ExtractSelection(Selection=selection)<br>ec.UpdatePipeline()<br>

Thanks for the quick response.  I tried the following in the python<br>
window with the integrated variables highlighted in the GUI ....<br>
<br>
>>> ss = GetActiveSource()<br>
<span class="">>>> selection = SelectCells(query="id==0")<br>
>>> ec = ExtractSelection(Selection=selection)<br>
>>> ec.UpdatePipeline()<br>
</span>>>> PlotSelectionOverTime(Input=ss,Selection=ec)<br>
<br>
and the below output was spit to the the Output Messages indicating<br>
that nothing was selected.  Does the above syntax make sense to you?<br>
