Value Series: saving results of Extract Peak operator as macro / example set

ck

I am doing a "Fourier Transformation" and use the "Extract Peak" operator of the Value Series extension.

My problem is: how do i get the peak values out of the series world, like saving the results as macros or in a "normal" example set? If I use "Series to Data" I only get the "Fourier Transformation", but not the result of the peak extraction which seem to be called "single values" or "single attributes".

 

Here is a little example:

 

<?xml version="1.0" encoding="UTF-8"?><process version="7.2.002">
  <context>
    <input/>
    <output/>
    <macros/>
  </context>
  <operator activated="true" class="process" compatibility="7.2.002" expanded="true" name="Process">
    <parameter key="logverbosity" value="status"/>
    <process expanded="true">
      <operator activated="true" class="series:generate_series_sinus" compatibility="7.2.000" expanded="true" height="68" name="Generate Series (Sinus)" width="90" x="45" y="34">
        <list key="frequency">
          <parameter key="1000.0" value="1.0"/>
          <parameter key="600.0" value="2.0"/>
        </list>
      </operator>
      <operator activated="true" class="series:window_transformation" compatibility="7.2.000" expanded="true" height="68" name="Window Transformation (3)" width="90" x="179" y="34"/>

        <parameter key="frequency_rescaling" value="true"/>
        <parameter key="sample_rate" value="44100.0"/>
      </operator>
      <operator activated="true" class="series:extract_peak" compatibility="7.2.000" expanded="true" height="68" name="Extract Peak" width="90" x="447" y="34"/>
      <connect from_op="Generate Series (Sinus)" from_port="output" to_op="Window Transformation (3)" to_port="series"/>
      <connect from_op="Window Transformation (3)" from_port="series" to_op="Fast Fourier Transformation (2)" to_port="series"/>
      <connect from_op="Fast Fourier Transformation (2)" from_port="series" to_op="Extract Peak" to_port="series"/>
      <connect from_op="Extract Peak" from_port="series" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

Thanks in advance. :-)

Just in case someone else is having that probem.
I did not find a solution using the "Data to Series" / "Series to Data" combination, but could solve it with "Process Series".
Had to transpose my Data for this operator and used "Extract Macro" to generate the needed End Attribute value.
