Hi Kaushal,
You should be able to set the pointer on a single value slider using a parameter passed on the URL, but you can't assign a parameter to a range slider (two values). Parameters only support a single value in the current release, and parameters can only be associated with character or numeric data items. Dates are not supported yet.
However, there's a workaround. See Renato_sas's step-by-step article Date parameters in SAS Visual Analytics.
