Using Master Item formatting with Measures
If the measure has been created from a Master Item (Figure 3), you can choose to enable Master measure formatting, which means formatting for the measure will be taken from the master item definition (you can find master items in the Custom Objects menu in the left-hand panel).
This can help you apply formatting quickly across multiple charts when you slide the Master measure formatting toggle to the right.

You can also:
- Specify a Bar Color, set the Bar Opacity.
- Show or hide Data Values (you can choose to Show totals on stacks in a stacked chart).
- Select Include only bars (only show totals for measures represented as bars when Show totals on Stacks is selected).
- Select Show all values, or Show only totals.
- Enable Custom Tooltip to use your own HTML code for the tooltip.

Setting Sorting options
The Sorting tab controls how you order your data (Figure 5) and has a default setting of Auto for both dimensions and measures.
Switch to Custom sorting to set your own values and sort by expression, numerically or alphabetically.
