Don’t forget the tool-tips

Ed Connect

The tools

• Using Shelves and Cards
• Changing the mark or geometry of the graphic

Tools Activity

• You and a partner will take one of the following readings and build a 1-minute guide on how to use that option.
  • You get 5 minutes to review and prep the guide.
• Each of you will present your 1-minute guide to the class.

Using Shelves and Cards

• The Columns shelf creates the columns of a table (x-axis), while the Rows shelf creates the rows of a table (y-axis). You can place any number of fields on these shelves.
• Right-click (control-click on Mac) the row or column you want to hide, and then select Hide.
• Open the field menu for a field that has hidden columns or rows and select Show Hidden Data.
• The Pages shelf lets you break a view into a series of pages so you can better analyze how a specific field affects the rest of the data in a view.
• Measure Values and Measure Names
• Summary Cards
