Paolo Alto GlobalProtect VPN Client is the GW VPN. You must be connected to the GW VPN (Virtual Private Network) to access GW Tableau (VPN is not required for GW Power BI). If you are not familiar with using VPN at GW, please refer to the download and setup instructions provided by GW IT.

Tableau is spinning and does not load the page

GW BI currently maintains two reporting tools.

GW Insight (Tableau):
Referred to as "Dashboards". Note: To access, VPN connection is required .

GW Power BI
Referred to as "Reports"

How do I find reports or dashboards?

Business Intelligence Services' Content Catalog!

The Content Catalog provides a way to find reports and dashboards across the university's data domains. You will also find the link to our Data Governance Center for the associated business terms. This catalog is refreshed daily as updates and additions are put into Collibra.

See the catalog's glossary of terms.

What is the difference between CSV and Excel when downloading in Tableau?

When you plan to download data from any GW Insight/Tableau dashboard, you will need to choose between two formats:

CSV Format

Use CSV (.csv) file format (preferred method) when:

You need every column and every row of data for your analysis.
The formatting and layout (e.g., predefine groups) are not important.

Note: CSV files can be opened and saved in Excel. Since merged cells are eliminated by the CSV format, you can easily filter and manipulate the data columns. Read more about CSV format.

Excel Format

Use Excel (.xls or .xlsx) format on all other occasions:

To keep the GW Dashboard data grouping or predefine layout.
To present data as is or you plan to add charts and visualizations, or any Excel functions

How do I know which reporting tool(s) to use?

The BI product strategy seeks to serve the majority of user data needs through professionally designed, certified dashboards delivered with Tableau, and the remaining needs with the detailed and build-your-own capabilities of Power BI. Keep this "80/20" guideline in mind when seeking resources for your work, and generally start by seeking to identify the appropriate Tableau dashboard for your use.

You can refer also to the Content Catalog for information such as description, location and business glossary for available reports and dashboards.

What trainings are available to me?

Our training webpage outlines webinars and training resources for users to become familiar with BI's products and platforms.

What is Collibra and how do I use it?

The GW Data Governance Center (DGC), often dubbed Collibra in reference to the underlying software platform, serves as the single source of truth for all GW data governance and stewardship activities, and is where business definitions and data assets are catalogued, defined, and governed.

Dashboards and reports created by the BI team are certified in collaboration with the Data Governance team and relevant Data Stewards, and documented within the DGC to ensure all reports and dashboards are consistent, trusted, and high-quality.

We have synced the Content Catalog with the DGC entry for a report, dashboard,and worksheet. You will find a description, glossary of the business terms included along with their definitions, and a link to the asset itself. On certified assets in Tableau and Power BI, you will find a link to the relevant DGC entry.

How do I navigate a Tableau dashboard?

Use the filters at the top of the dashboard to generate or update the summary table.

Click on any column, row, or cell in the summary table to generate secondary filters and the detail table (e.g., student level information).

Secondary filters display additional aggregate information. Click on one or more cells to further filter the detail table. Use CTRL + click to select more than one cell from a single filter.

After making all of your selections you can save your view, so it will be available upon next login without having to reapply all filters and selections.

You can subscribe to your view to receive email updates at a regular interval. The email will include an image with a link back to the dashboard. NOTE: Only use schedules labeled *SITE USERS*.

Use the Share option to make your saved view available to others.

How do I create a custom view in Tableau?

A custom view is a saved version of a Tableau dashboard with your selections and filters applied. You can create several views of one dashboard. You can also set one of the views as a default for each time you open the dashboard and make your view visible to others.

Step 1: Open the dashboard and apply the filters for your view

Step 2: Select "View" in the top menu bar, name your view, select checkbox options and save

Step 3: Your view is now available in the top menu bar

Step 4: Manage your view(s) by selecting the "View" menu option

For more information about custom views, go to https://help.tableau.com/current/pro/desktop/en-gb/customview.htm

How do I download data from Tableau or Power BI?

Data from any table in the dashboard can be downloaded. To ensure you download the desired table (usually the detail table at the bottom of the dashboard), click on a column or cell in the table before clicking the Download button from the menu at the top. This will ensure the selected table is the default in the download menu. NOTE: Data can be downloaded as XLSX or CSV; they have different formatting in the output so you may wish to download both and see which meets your needs. See answer above, "What's the difference between Excel and CSV" for specific details.

Power BI

To download data as an XLSX, on the "Detail" page, click on the ellipsis (three dots) on the top right corner of the table you wish to download.

Select 'export data' from the drop down.

The Excel file will automatically download and open.

What if I don’t see all the data fields I need on a Tableau dashboard?

Download the Table

In a Tableau dashboard not all fields are always displayed in the visual of the detail table, but additional columns are available once you download the table. See tutorial above on "how to download".

Submit a Request

If after downloading there are still columns not present that would be helpful in answering your questions you can submit a ticket. There is no guarantee that the columns will be added.
