How to change number formatting
Are you trying to represent percentages but instead of 2,15% – as you added your numbers in the data – your visualization is showing 215 as a value?
You will need to change the number format.
- Switch to the Data tab and check what type of decimal separator your data uses. In this example, it's a comma.
- Switch back to the Preview tab and go into the Number formatting settings. Here, make sure that the decimal separator matches the one used in your data.
- If you would like to display your number as a percentage, you will have to add a suffix. You can do this under "Number styling" > "Suffix".
