    Hi Leandro,
    that's quite easy if you use the ROCChart. Here's an example process: 
    <operator name="Root" class="Process" expanded="yes">
        <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
            <parameter key="target_function"	value="sinus classification"/>
        </operator>
        <operator name="DecisionTree" class="DecisionTree">
            <parameter key="keep_example_set"	value="true"/>
        </operator>
        <operator name="ROCChart" class="ROCChart">
        </operator>
    </operator>
    Greetings,
      Sebastian
