Pages Shelf

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. When you place a dimension on the Page shelf you are basically adding a new row for each member in the dimension. When you place a measure on the Pages shelf, the measure is converted into a discrete measure.

The page shelf creates a view on a different page for each new row so you can easily flip through each view and compare them on a common axis. For example, the view below shows the Profit vs. Sales by Region for each day throughout the month.



You can see that it is difficult to see how these two measures have interacted from day to day. However, when you move the Day field to the Pages shelf and flip through the pages (one for each day) you can quickly discover hidden insights. In this example, it is interesting that the 19th is an especially big day in terms of sales and profit in the Western region.



When you add a field to the page shelf the Current Page card displays. Use this card to navigate through the pages.



There are three ways to navigate through the pages in a view.

Jump to a specific page

Select the member or value you want to view from the drop-down list on the Current Page card to display a specific page rather then scrolling through the entire sequence.



Manually Advance through the pages

You can manually advance through the sequence of pages by doing one of the following:

  • Use the forward and back buttons on either side of the drop-down list to navigate through the pages one at a time.

  • Use the Page Slider to quickly scroll forward and backward in the sequence of pages.

  • Use the keyboard shortcuts below to scroll forward and backward in the sequence of pages.
    F4 Starts and stops forward playback
    SHIFT + F4 Starts and stops backward playback
    CTRL + . Skip forward one page
    CTRL + , Skip backward one page

Automatically Advance through the pages

Use the playback controls to watch a slide show of the pages in the view. You can play forward, play backward, and stop. You can control the speed of playback with the speed controls in the bottom right corner of the card. The smallest bar indicates the slowest playback speed.



Page History

Optionally show page history using the Show History checkbox. When you show history, marks from previous pages are shown in addition to the previous page. Open the drop-down control for history to specify what marks to show and when to show them.



The history drop-down control has the following options:

  • Marks to show history for – select whether you want to show history for just selected marks, highlighted marks, marks that you’ve manually selected to show history for, or all marks. You manually show history for marks by right-clicking the mark in the view and selecting and option on the Page History menu.

  • Length – select the number of pages to show in the history.

  • Show – specify whether to show the historical marks, a line tracing through the previous values (trails), or both.

  • Marks – format the historical marks including the color and how much to fade them If the color is set to automatic, the marks will either use the default mark color or the color encoding on the Color shelf.

  • Trails – format the lines that are drawn through the historical marks. This options is only available if Trails is selected in the Show options.

Note:

Page trails may not display if there are multiple marks per color on a page. Make sure that the level of detail for the view is less than or equal to the level of detail on the pages and color shelves.
