In this example, that connection is called 'Sheet1 (master date list)'

Create a table that contains a master list of all possible dates, and create a new connection to that list.This option will not work for a range of dates. Double-click in the data pane to add the field to the view.In the Drop Field dialog, select MY(Date) and click OK.In the formula field, create a calculation similar to the following:.In this example, the calculated field is named 'Orders Placed' In the Calculated Field dialog box that opens, do the following, and then click OK:.Select Analysis > Create Calculated Field.Add the 'Sheet 1' table to the canvas area.Navigate to the Data source tab in Tableau Desktop.In this example, that table is called 'Master Date List' Create a table that contains a master list of all possible dates, which will be joined to the original data connection.This option requires that one date field always come before another date field, and works best when the two dates fields are defining a range.

Double-click in the data pane to add the field to the view IF DATETRUNC('month', ) = DATETRUNC('month', ) Create a calculated field with a name like 'Orders Shipped' with a calculation similar to the following:.In the Edit Alias dialog, type in a new name and click OK.Right-click the header 'Distinct count of Order ID' in the view and select Edit Alias….In the Drop Field dialog, select CNTD(Order ID).Right-click and drag to Text on the Marks card.In the Drop Field dialog, select MY(Order Date) with the blue # icon and click OK.Right-click and drag to the Rows shelf.Choose one date field to create the date axis or headers.In this example, every row is a month, therefore both and need to have at least one order for every month. Anyone can access the navigation charts for these rivers, which show depth contours, buoys, lights, known hazards, and reference landmarks.This option requires that every date field have at least one record for every date bin in the view. Rivers included in the Inland Electronic Navigation Chart (IENC) program include the Allegheny River, Arkansas River, Atchafalaya River, Black Warrior-Tombigbee Rivers, Cumberland River, Green River, Illinois River, Kaskaskia, Kanawha River, Lower Mississippi River, Missouri River, Monongahela River, Ohio River, Ouachita River, Red River, Tennessee River (including the Tellico, Hiwassee, Clinch and Emory Rivers), Tennessee-Tombigbee Waterway, Upper Mississippi River, and the White River. America’s inland waterways move millions of tons of commodities every year, and the work of surveying, charting, and dredging sediment is continually ongoing due to the dynamic conditions and constant change happening along any given river. The Inland Electronic Navigation Chart (IENC) program covers thousands of miles of navigable waterways. Army Corps of Engineers produces charts for America’s inland rivers through the Inland Electronic Navigation Chart program. The National Oceanic and Atmospheric Administration (NOAA) Office of Coast Survey produces charts for coastal and Great Lakes areas, and the U.S.

Historically these charts have been printed and distributed on paper, but modern communications systems allow for electronic charts that are able to be updated as new information becomes available. Nautical charts provide critical information to mariners in support of safe navigation.
