     • List - This selection presents a form so you can define a dropdown list of individually selectable items to use as the current value. You can either type the values in the Value list or copy and paste a list of values from a different source by clicking Paste from Clipboard. In the Paste Data dialog, choose the required options from the drop-down and then click Paste.
       
     • Range - This selection presents a range input selector for setting the current value. The Step Size determines how the value will increment either up or down to achieve the nearest acceptable value. If DATE or DATE TIME data types are used, the step size can increment in units of years, quarters, months, weeks, days, hours, minutes or seconds. The data type determines the availability of these options. For example, a string data type does not support range. 
       
   • When finished, click Save. The parameter is displayed in the Parameters pane. When you hover your mouse on the parameter, Visual Analytics will display the tooltip.
