   + DATENAME('year', [Range 1 - Start])) + " - " 
   + str((DATENAME('month', [Range 1 - Stop]))+ " " 
   + DATENAME('day', [Range 1 - Stop]) + ", " 
   + DATENAME('year', [Range 1 - Stop])) 

Calculated Field: Dynamic Range 2

2. In the Calculated Field dialog box that opens, name the calculated field Dynamic Range 2
3. Enter the following formula and then click OK:

4. STR((DATENAME('month', [Range 2 - Start]))+ " " 
   + DATENAME('day', [Range 2 - Start]) + ", " 
   + DATENAME('year', [Range 2 - Start])) + " - " 
   + str((DATENAME('month', [Range 2 - Stop]))+ " " 
   + DATENAME('day', [Range 2 - Stop]) + ", " 
   + DATENAME('year', [Range 2 - Stop])) 

Step 3: Create the visualization

Create the Views

1. In Sheet 1
   1. From Dimensions, drag Order Date to the Columns shelf.
   2. From Dimensions, drag Customer and Product Name to the Rows shelf.
   3. In the view, right-click the Order Date header, and select Hide Field Labels for Columns. 
   4. Right-click the four parameters and then select Show Parameter Control for all of them.
2. Sheet 2
   1. From Dimensions, drag Dynamic Range 1 to the Text shelf.
   2. Adjust how the sheet will fit as desired.
3. Sheet 2
   1. From Dimensions, drag Dynamic Range 2 to the Text shelf.
   2. Adjust how the sheet will fit as desired.

Create the Dashboard

1. From Dashboard, drag Sheet 1 onto the dashboard.
2. In the Dashboard pane, click Floating under the Objects section.
