+====== 2D Horizontal Bar ======
+===== Draw horizontal bars on a Report Graph =====
+**This is especially useful for creating ON/OFF bars for EMG data**. An example of creating a simple horizontal line is provided after this example.
+|This example creates a line that is ON/OFF to express when an EMG signal is expected to be ON/OFF through the gait cycle (red line in picture on right):  |  {{:BarGraph3.jpg}}|
+As a simple example, create a P2D signal representing the frames and ON/OFF values
+<code>
+! make the GLOBAL workspace active
+Select_Active_File
+/FILE_NAME=GLOBAL
+! /QUERY=
+;
+! create a signal of ON/OFF values
+Evaluate_Expression
+/EXPRESSION=LIST(VECTOR(0,1),VECTOR(1,0),VECTOR(2,1),VECTOR(3,0),VECTOR(4,1))
+/RESULT_TYPES=P2D
+/RESULT_FOLDERS=BARS
+/RESULT_NAME=BAR1
+! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE
+;
+</code>
+The resulting signal is:

+===== Simple Horizontal Line =====
+|This example is to create a simple horizontal line straight across using P2D signals (purple line in graph on right):  |  {{:P2D_Horizontal_Graph.png}}|
+Create the horizontal line as a P2D signal:
+<code>
+Evaluate_Expression
+/EXPRESSION=
+ LIST (
+  VECTOR(1,50) ,
+  VECTOR(101,50) )
+! /SIGNAL_TYPES=
+! /SIGNAL_FOLDER=ORIGINAL
+! /SIGNAL_NAMES=
+ /RESULT_TYPES=P2D
+ /RESULT_FOLDERS=HORIZON
+/RESULT_NAME=GLOBAL::FIFTY
+! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE
+;
+</code>
