Parameter Encoding and Delimiters
Parameters should be placed in a query enclosed by curly brackets. For example:
{symbol}
Three types of parameters are available:
q Text (the default)
q Date/Time (through the Time Special Parameters)
q 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:
q data connectors to define a query, subscription, and connection settings
q R Transform to define an R script
q Python Transform to define a Python script
q the resulting dashboard for visualization titles
q Text label controls
q 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.
