It can written to a file which can be read e.g. by gnuplot. Alternatively, the collected data can be plotted by the GUI. This is even possible during process runtime (i.e. online plotting).<br/> Parameters in the list <code>log</code> are interpreted as follows: The <var>key</var> gives the name for the column name (e.g. for use in the plotter). The <var>value</var> specifies where to retrieve the value from. This is best explained by an example: <ul> <li>If the value is <code>operator.Evaluator.value.absolute</code>, the ProcessLogOperator looks up the operator with the name <code>Evaluator</code>. If this operator is a <A HREF="../../../../com/rapidminer/operator/performance/PerformanceEvaluator.html" title="class in com.rapidminer.operator.performance"><CODE>PerformanceEvaluator</CODE></A>, it has a value named <var>absolute</var> which gives the absolute error of the last evaluation. This value is queried by the ProcessLogOperator</li> <li>If the value is <code>operator.SVMLearner.parameter.C</code>, the ProcessLogOperator looks up the parameter <var>C</var> of the operator named <code>SVMLearner</code>.</li> </ul> Each time the ProcessLogOperator is applied, all the values and parameters specified by the list <var>log</var> are collected and stored in a data row. When the process finishes, the operator writes the collected data rows to a file (if specified). In GUI mode, 2D or 3D plots are automatically generated and displayed in the result viewer. <br/> Please refer to section Advanced Processes/Parameter and performance analysis for an example application.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: ProcessLogOperator.java,v 2.27 2006/03/27 13:21:58 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>Simon Fischer, Ingo Mierswa</DD><DT><B>To do:</B></DT> <DD>Use IOObjects for logging as well (e.g. <A HREF="../../../../com/rapidminer/operator/performance/PerformanceVector.html" title="class in com.rapidminer.operator.performance"><CODE>PerformanceVector</CODE></A>)</DD></DL><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Field Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/visualization/ProcessLogOperator.html#PARAMETER_COLUMN_NAME">PARAMETER_COLUMN_NAME</A></B></CODE><BR> The parameter name for "operator.OPERATORNAME.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/visualization/ProcessLogOperator.html#PARAMETER_FILENAME">PARAMETER_FILENAME</A></B></CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/visualization/ProcessLogOperator.html#PARAMETER_LOG">PARAMETER_LOG</A></B></CODE><BR> </TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== -->⌨️ 快捷键说明
