Parameter Encoding and Delimiters

Parameters should be placed in a query enclosed by curly brackets. For example:

{symbol}

Three types of parameters are available:

Text (the default)
Date/Time (through the Time Special Parameters)
Numeric (through selecting a numeric field, or using a Numeric Action Slider)

Each can be encoded appropriately.

For text parameters, the full syntax is as follows:

{[parametername]:[delimiter]}

For example:

{symbol:,}

The colon separates the parameter name from the delimiter string. If there is only a single value, then the delimiter is not utilized.

For numeric and Date/Time parameters the full syntax is as follows:

{[parametername]:[display format]}

For example:

{TimeWindowStart:yyyy-MM-dd HH:mm:ss}

{volume:#,##0}

{minresult:#,##0.00}

Parameter encoding can be used within:

Data connectors to define a query, subscription, and connection settings
R Transform to define an R script
Python Transform to define a Python script
The resulting dashboard for visualization titles
Text label controls
Visualizations to define variable titles

NOTE: The original $ format of prepending a parameter value with the dollar symbol is still supported for backwards compatibility reasons, but it is more limited in what it can achieve and should be avoided.
