By default, Tableau uses your Windows Region and Language settings to format numbers. However, if the Windows settings do not reflect how you want to show them, you can set a different locale in the Tableau Format window.
The following steps show how to set Swiss German currency, using the same view as in the previous section as an example.
Right-click the axis in the view and select Format.
On the Axis tab, under the Scale area, select the Numbers drop-down list, and then select Currency (Standard).
In the Locale drop-down list, items appear in a Language (Country) format. So for this example, you would select German (Switzerland).
The view updates to show the sales figures in Swiss Francs, formatted for German language.
Tip: You can change the default currency setting, so that every time you drag the Sales measure to a view that you create with this data connection, it shows the settings you want. In the Measures pane, right-click the Sales (or other monetary measure), and select Default Properties > Number Format.
