Understanding Fixed Size Dashboards

In Tableau, what happens when you set a dashboard's size to Fixed Size?

A The dashboard automatically adjusts to fit the screen size of any device.

B The dashboard size is set based on the device type detected by Tableau.

C The dashboard size stays constant regardless of the device or window size.

D The dashboard size changes only when the browser window is resized.

💡 Hint

Think about what 'fixed' means in everyday life, like a fixed price or fixed schedule.

Fixed Size means the dashboard dimensions do not change. It stays the same width and height no matter what device or window size is used.

Choosing Automatic Sizing

What is the main advantage of setting a Tableau dashboard to Automatic size?

A It allows the dashboard to resize dynamically to fit the available screen space.

B It locks the dashboard size to a specific pixel dimension.

C It disables any resizing and keeps the dashboard static.

D It sets the dashboard size based on the largest worksheet inside it.

💡 Hint

Think about how websites adjust when you resize your browser window.

Automatic sizing lets the dashboard grow or shrink to fill the screen or window size, making it flexible for different devices.

Calculating Dashboard Width for Device Layout

You want to create a calculated measure in Tableau to determine the dashboard width based on device type. The logic is:

• If device is 'Desktop', width = 1200
• If device is 'Tablet', width = 800
• If device is 'Phone', width = 400
• Otherwise, width = 1000

Which calculated field formula correctly implements this?

A CASE [Device] WHEN 'Desktop' THEN 1200 WHEN 'Tablet' THEN 800 WHEN 'Phone' THEN 400 ELSE 1000 END

B IF [Device] = 'Desktop' THEN 1200 ELSEIF [Device] = 'Tablet' THEN 800 ELSEIF [Device] = 'Phone' THEN 400 ELSE 1000 END

C IF [Device] = 'Desktop' THEN 1200 ELSE IF [Device] = 'Tablet' THEN 800 ELSE IF [Device] = 'Phone' THEN 400 ELSE 1000 END

D SWITCH([Device], 'Desktop', 1200, 'Tablet', 800, 'Phone', 400, 1000)

💡 Hint

Remember Tableau uses CASE statements for multiple conditions.

Option A uses the correct CASE syntax in Tableau to check device types and assign widths accordingly.

Best Practice for Responsive Dashboard Design

Which dashboard sizing option in Tableau best supports creating a dashboard that looks good on both desktop and mobile devices without manual resizing?

A Fixed Size with 1200x800 pixels

B Automatic sizing with floating layout containers

C Fixed Size with 400x600 pixels

D Range sizing with minimum 800 and maximum 1200 pixels width

💡 Hint

Think about how a dashboard can adapt between a phone and a desktop screen.

Range sizing allows the dashboard to resize between a minimum and maximum width, making it flexible for different screen sizes while maintaining design control.

Troubleshooting Dashboard Size Not Changing

You set your Tableau dashboard size to Automatic, but when you view it on different devices, the size does not change. What is the most likely cause?

A You did not publish the dashboard to Tableau Server.

B You used floating objects that have fixed pixel sizes inside the dashboard.

C You have fixed the size of all worksheets inside the dashboard.

D You set the dashboard to Range sizing instead of Automatic.

💡 Hint

Think about what elements inside a dashboard can prevent resizing.

Floating objects with fixed pixel sizes do not resize automatically, which can prevent the dashboard from adjusting size even if set to Automatic.
