Property Value

Type	Description
String	A format pattern.

Remarks

A pattern can contain regular text (displayed as is) and placeholders in braces. You can apply a format specifier to a placeholder to format numeric and date/time values. Use a colon to separate a placeholder and specifier.

The following table contains the available placeholders:

Pattern	Description
{A}	Displays a series point argument.
{V}	Displays a series point value.
{VP}	Displays series point values as percentages (for pie, funnel, and full-stacked series).
{S}	Displays the series name .
{G}	Displays the name of a stacked group.

See the following topics for more information about specifiers:

• Standard numeric format strings
• Standard date and time format strings

If a pattern starts with a placeholder in the XAML markup, insert empty brackets into the beginning of the pattern as follows: “{}{V}”.
