A text renderer's purpose is to convert a raw value into a form that is more recognizable and informative to a human user. The ways to render raw values depend upon the data type of value to be rendered. As such, only the renderer types that apply to the current point's data type are listed in the Type selection.
The Binary renderer allows the user to define a text label to represent each of the two binary states (i.e. 0 and 1). Any labels can be provided. Also, a distinctive colour may be defined for each state. Typical examples of labels include off/on, stopped/running, or false/true, but any text can be entered.
The Plain renderer is the default binary renderer. Displays the unaltered raw value, i.e. 0 and 1.
The Analog renderer allows the user to define a Format used to determine things like the number of decimal places to display, and whether thousands should be delimited. (See the "Number format" documentation). A Suffix can also be added to display the units of the value. Suffixes can contain HTML entities such as ° (written as '°') for display within HTML pages. See http://www.w3.org/TR/REC-html40/sgml/entities.html for more information on HTML entities.
The Plain renderer is the default numeric renderer. Displays the unaltered raw value.
The Range renderer allows the user to define a number Format (see the "Number format" documentation for more information), as well as an arbitrary number of textual values to represent various numeric from/to ranges. Each of these ranges can also be assigned a distinctive colour. The number format is only used if the value does not fall within a defined range. For example, the range "cold", "normal", and "hot" may be defined for a temperature point, with appropriate colours for each.
The Plain renderer is the default multistate renderer. Displays the unaltered raw value.
The Multistate renderer allows the user to define an arbitrary number of textual values to represent various point states. Each of these states can also be assigned a distinctive colour. If a state occurs which is not assigned to a label, the raw value is displayed. Typical label sets include on/off/disabled, or off/warm/cool.
The Plain renderer is the only alphanumeric renderer. Displays the unaltered raw value, including an optional Suffix.
