A Visual dashboard is a type of visual project that presents
interactive or persistent data to a wide range of users.
About this task
Visual dashboards can simultaneously draw data from multiple, heterogeneous data sources
and present the data using a variety of graphs, charts, and graphical widgets. Using QMF for Workstation,
content developers can create a visual dashboard that can be viewed by multiple users with either
QMF for Workstation or QMF for WebSphere®.
Note: You can view
previously designed visual dashboards in QMF for WebSphere, but you can not design them. The
Visual Designer perspective is not available.
The following steps
outline the tasks that you will perform when creating or editing visual dashboards:
Procedure
- Activate a visual dashboard in the workstation editor window.
You can activate a visual dashboard in the workstation editor window
in one of the following ways:
- Create a new visual dashboard using the Create New Visual
Dashboard wizard.
- Open an existing visual dashboard.
- Open the Visual Designer perspective.
The Visual Designer perspective presents an
editor window and several views and menus that you will use when you
work with visual dashboards. You can open the Visual Designer perspective
by using either the Open perspective toolbar
button or by selecting .
- View the key components of the visual dashboard as listed
in the Project Explorer view. Each visual dashboard
is listed under the Visual Dashboards node
in the Project Explorer tree. Each visual dashboard
will have the following folders:
- Connections
- Globals
- Queries
- Scenes
- Create data source connections.
Visual dashboards are intended to be shared across the enterprise. In order to facilitate sharing
and distributing visual dashboards, QMF for Workstation does not tie the queries that are included in a visual dashboard to a specific data source.
Instead, it ties the query to a connection information alias.
You must set up a connection information alias for each
data source used to obtain data for the visual dashboard. For information
about setting up a connection information alias, see Specifying
data source connections for visual projects.
- Specify the first query that will supply data for the visual
dashboard.
You can specify an existing query or create
a new query. When you specify the query the system prompts you to
associate the query with a connection information alias. The connection
information alias identifies the data source against which the query
runs. For information about setting up queries, see Specifying queries for visual projects.
- Design the first scene for the dashboard. A visual dashboard
consists of one or more scenes.
A scene is the container
(similar to a presentation slide) that will hold all the elements
used to display your data. After creating a new visual dashboard,
the system provides one default scene. You can choose to have only
one scene in your visual dashboard or you can add additional scenes.
- Insert objects into a scene.
The objects
that you can insert are displayed in the Palette view
and are organized on individual palettes based on their type. From
the Palette view select the objects that you
want to insert into your scenes.
- Modify the object's properties in the Properties view.
By modifying an object's properties you set the values that
determine how the object looks and behaves. You can use the Expression
Designer to help you specify an object's properties.
- Insert the layout objects
In a visual dashboard
scene layout objects display query results.
When you insert
a layout object the system prompts you to associate the object with
a query that is contained in the Queries folder.
You can add queries to your Queries folder
at any time during the process of creating your dashboard.
Layout
objects can present data in many ways. For most layout objects, you
display the results of multiple queries in a single layout. For example,
you might create a single XY chart that displays sales figures derived
from one query and spending figures derived from another query. You
can add multiple layout objects. When you place layout objects, you
can pass query result information from a higher level layout object
to a lower level layout object. Because you have the ability to pass
this information, you can use the placed layout objects to display
more detailed information that relates to a specific data value.
- Use the Events view to assign the
different navigation options.
By assigning navigation
options to scenes and objects, you set a path through the dashboard.
One form of navigation is to define dependencies between dashboard
control objects (such as combo or list box objects) and data-driven
layout objects (such as a grid or bar chart object) using the Connectivity tool
from the Palette view.
- Run the visual dashboard.
Each time that
you click the Runtime tab, you are actually
running the visual dashboard object. By performing this step you can
review how the results will display at run time. Think of this step
as a test-run of your dashboard that allows your to improve upon the
design before saving and deploying the dashboard.
- Save the visual dashboard.
When you have
completed designing or editing the visual dashboard, you can save
the dashboard and copy it to one or more workspaces for distribution
to other users.
