How to create and populate the information button in Tableau desktop.
Step by step guide:
Create a new sheet
Create a calculated field containing “i” only. It can be called ‘Info button’
Add this calculated field to the Text mark in the marks card
Click on Text in the marks card and select the three dots that appear next to the ‘Text:’ field
In the text editor that appears, set the font to ‘Webdings’. This font appears as all symbols but can be searched for in the drop down fonts menu
Set the size to 48
Set the colour to York pink (#e31a82)
Drag the sheet into the relevant spot in the dashboard and ensure it’s set to show ‘Entire view’
