Dashboards are a way to combine several related reports into one unified viewing space. Existing reports can be added to a Dashboard, and new Visualizations can be created directly on the Dashboard itself. Images, text, other web sites, and interactive filters can also be added. Dashboards can be exported as a Chained Report from the Dashboard Designer.
The Dashboard Designer
The Dashboard Designer is comprised of three sections: the Toolbar, the Canvas and the Tile Properties Pane.
Each element on a Dashboard is a contained within a rectangular tile that can be resized and dragged to the desired location. Tiles are arranged onto a grid, and can snap into place next to each other.
There are several useful keyboard shortcuts available in the Dashboard Designer. They are listed in the Keyboard Shortcuts article.
The top of the Dashboard Designer contains a Toolbar for creating and interacting with the canvas and the tiles.

The Dashboard Designer Canvas
Each element on a Dashboard is a contained within a rectangular tile that can be resized and dragged to the desired location. Tiles are arranged onto a grid, and can snap into place next to each other.
Tiles contain four elements:
Anatomy of a tile in the Dashboard Designer
Several different types of tiles can be added to the canvas:
New tiles can be added to the canvas either one of two ways:
Tiles can be dragged to an empty location to fill the space, to the side of an empty location to take up a portion of the space, or over another tile to place it adjacent and resize the other tile to fit. Tiles can then be resized by dragging the handles to alter the tile size.
Dragging a new tile over an existing tile on the left
Dashboards can scale to fit different screen sizes. Click the Canvas Format
icon on the Toolbar to open the Canvas Format menu.
In v2021.2, the following Size options are available:

To set the size of the Dashboard canvas, choose a common US or ISO page size from the dropdown, or choose Custom to enter a specific Height and Width.
Choose either Portrait or Landscape to orient the selected page size on the canvas. These dimensions and orientation are also used when exporting the Dashboard as a PDF Snapshot.
The Scale in Dashboard Viewer checkbox sets how the Dashboard will fit the tiles to the canvas.

Caution
Changing the Scale in Dashboard Viewer mode or choosing a different Stretch Canvas option will automatically rearrange the position and size of the tiles on the canvas.
Stretch Canvas to Fit Height and Width — the canvas stretches to fill the window both horizontally and vertically. This mode is similar to the Scale to Screen option in v2019.2–v2021.1. The values in the Height and Width inputs apply to the size of an export as a PDF Snapshot.
Stretch Canvas to Fit Width — the canvas stretches horizontally to fit the window, but the width of the canvas is fixed. This mode is similar to the Specify Height option in v2019.2–v2021.1. The value in the Width input applies to the size of an export as a PDF Snapshot and the size of the canvas.
In v2019.2–2021.2, the following Fit options are available:

Default options for the canvas background color, tile and tile header background colors, and tile border colors and widths can also be customized from the Canvas Format
menu under Style. These settings can be overridden for individual tiles through the respective tile’s Tile Properties Pane.
The following Tile Defaults are applied whenever a new tile is added to the canvas.
Tiles have a menu with some additional options.

The Tile Properties Pane in the Dashboard Designer
The Tile Properties Pane on the right side of the Dashboard Designer is where the look, feel and behavior of individual tiles on the canvas can be changed. It contains three tabs: Content, Style and Advanced.
The very top of the Tile Properties Pane contains the Tile Header section, including a text entry field for providing a title that can optionally displayed on the canvas. Clicking on the Show Header 
icon will hide it. Clicking on the Title Header Format
icon will show formatting settings for the tile header allowing the font type, size, alignment and styling to be applied. Clicking the Title Header Format
icon again will hide these settings.

Depending on the type of tile selected on the canvas, the availability of the tabs in the Tile Properties Pane will change. Tabs which are not available for a particular tile type will be grayed out. Each tile type has its own article with details of the respective tile properties. A list of tile types with links to more information is at the beginning of this article.
