+====== Metric To Fit Signal To Line ======
+Fit a signal to a line
+Y = mX + b
+and create Metrics for Slope (a), Intercept (b), Sigma m, Sigma b, CHI2, and Q (R^2)
+{{:MetrictoFitSignaltoLine.png}}
+==== Command ====
+<code>
+Metric_To_Fit_Signal_To_Line
+/RESULT_METRIC_NAME= The resulting name of the metric
+/RESULT_METRIC_FOLDER= The resulting folder of the metric
+/SIGNAL_TYPES= The signal type for the dependent variable
+/SIGNAL_NAMES= The signal name for the dependent variable
+/SIGNAL_FOLDER= The signal folder for the dependent variable
+/SIGNAL_COMPONENT= The signal component for the dependent variable
+/X_SIGNAL_TYPE= The signal type for the independent variable
+/X_SIGNAL_NAME= The signal name for the independent variable
+/X_SIGNAL_FOLDER= The signal folder for the independent variable
+/X_SIGNAL_COMPONENT= The signal component for the independent variable
+/GENERATE_MEAN_AND_STDDEV= Calculate the mean and standard deviation
+/APPEND_TO_EXISTING_VALUES= Append values to the existing result signal
+;
+</code>
+==== Result ====
+**The resulting signal has 6 components:**
+**Slope = m** -> Component 1\\
+**Intercept = b** -> Component 2\\
+**Siga = uncertainty in m** -> Component 3\\
+**Sigb = uncertainty in b** -> Component 4\\
+**Chi2 = chi square** -> Component 5\\
+**Q = The R^2 statistic** -> Component 6\\
+==== Legacy Parameters ====
+**Prior to Visual3Dv5.02.28:**\\
+**1.** The EVENT_SEQUENCE was defined only using a start/end event. This meant if there were multiple sequences, Visual3D would return NO_DATA. The original event names were:
+**/START_EVENT=**
+**/END_EVENT=**
+**2.** It was not possible to calculate the mean/standard deviation or append values
+In version 6 these parameters are converted into an Event Sequence.
