====== 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>
