Unit 3: Creating Your Dashboard in DTV¶

In this unit, you will learn how to create widgets in DTV to monitor battery status.

Prerequisites¶

Before you begin, please ensure the following.

The current OU has obtained and enabled Digital Twin Visualization. If not obtained, contact the system admin.
You need to be assigned the required asset permission and operation permission, and a menu group containing all menus in Digital Twin Visualization. If not assigned, contact the application administrator.

Step 1. Creating a Project and the Page¶

You need to create a project, and then a page to hold widgets.

Log in to EnOS Application Portal and select Digital Twin Visualization from the application list.
Select Dashboards > Dashboards from the left navigation pane.
Select New Project, and enter the name Demo. Select OK to create the project.
To create a new page, select New Page.
- For Name, enter Smart Battery Dashboard.
- For Project, select Demo, the project that you just created.
- For Template, leave it blank.
Select OK to go to the Page Editor. Your page is created.

Step 2. Setting Your Overall Page Layout¶

Now you can configure the page to display the data.

Switch the theme to green in the right Page Settings. You can also change Background Color or upload your own Background Image.

Step 3. Creating a DTV Widget¶

Now, you will create and edit a DTV widget on the page you created.

You can choose many widgets on DTV for the best practice of data display and analysis. For instance:

Donut Gauge is good for measuring and displaying progress.
Horizontal Bar Chart is good for comparing data.
Map is good for displaying geographical information.
Mix Chart is good for visualizing and comparing trends.
Pie Chart is good for comparing and displaying the ratio of each data to the total.
Table is good for displaying complex data in an organized tabulated form.
Heat Map is good for comparing massive data and identifying anomalies by displaying data as color blocks.

For more information about other widgets on DTV, see Widgets.

Step 4. Configuring Data Link¶

Sometimes while viewing the data status of all batteries, it may also be desirable to view the data status of individual batteries or batteries in a single region. Adding a global filter after all widgets have been added will allow linkage between widgets. For example, if you select a single battery, the data displayed by all widgets will be filtered by that battery and displayed as data for that single battery. Select a region and all widgets will automatically display data for that region only.

Asset Filter¶

To add a Global Filter on assets, select Filters on the top toolbar.

Title: Asset.
Key: asset as the parameter key.
Attributes: Enable Visible on Page and Accepting External Parameters.
Filter Type: Multi-Select Dropdown.

Name/Value: AssetName - AssetName.

District Filter¶

To add a Global Filter on districts, select Filters on the top toolbar.

Title: District.
Key: District as the parameter key.
Attributes: Enable Visible on Page and Accepting External Parameters.
Filter Type: Single-Select Dropdown.
