Text Formatting Codes for Bargraphs/Joysticks

Text formatting codes for bargraphs provide a mechanism to allow a portion of a bargraphs text to be provided dynamically generated information about the current status of the level (multistate and traditional). These codes would be entered into the text field along with any other text.

The following is a code list used for bargraphs:

Bargraph Text Code Inputs

Code	Bargraph	Multi-State Bargraph
$P	Display the current percentage of the	Display the current percentage of the
	bargraph (derived from the Adjusted	bargraph (derived from the Adjusted
	Level Value as it falls between the	Level Value as it falls between the
	Range Values)	Range Values)
$V	Raw Level Value	Raw Level Value
$L	Range Low Value	Range Low Value
$H	Range High Value	Range High Value
$S	N/A	Current State
$A	Adjusted Level Value (Range Low Value	Adjusted Level Value (Range Low Value
	subtracted from the Raw Level Value)	subtracted from the Raw Level Value)
$R	Low Range subtracted from the High	Low Range subtracted from the High
	Range	Range
$$	Dollar sign	Dollar sign

The codes on a button may be modified by changing the text on a button via a VT command. When one of the Text Formatting Codes is encountered by the firmware, it is replaced with the correct value. These values are derived from the following operations:

Formatting Code Operations

Code	Operation
$P	(Current Value - Range Low Value / Range High Value - Range Low Value) x 100
$V	Current Level Value
$L	Range Low Value
$H	Range High Value
$S	Current State (if regular bargraph then resolves to nothing)
$A	Current Value - Range Low Value
$R	Range High Value - Range Low Value

Given a current raw level value of 532, a range low value of 500, and a high range value of 600, the following text formatting codes would yield the following strings as shown in the table below:

Example

Format	Display
$P%	32%
$A out of $R	32 out of 100
$A of 0 - $R	32 of 0 - 100
$V of $L - $H	532 of 500 - 600
