This topic describes the purpose of the Pattern Editor. It also explains the editor's sections and how to use it to create a pattern at design time.
The Pattern Editor is used to simplify text customization of series labels, axis labels and legend items. The editor contains many built-in predefined placeholders that can be used with different format specifiers to create patterns for date-time, numeric, currency and other data types.
The Pattern Editor can also be used to format text displayed in crosshair labels (the CrosshairAxisLabelOptions.Pattern, SeriesBase.CrosshairLabelPattern, CrosshairOptions.GroupHeaderPattern properties) and within tooltips (the SeriesBase.ToolTipPointPattern and SeriesBase.ToolTipSeriesPattern properties).
Click the chart's smart tag to invoke the Series Collection Editor;
- Locate the SeriesLabelBase.TextPattern property in the Series1 Properties tab;
Click the ellipsis button for this property.
Make sure the SeriesBase.LabelsVisibility property is set to true to show series labels in the chart.
In the invoked Pattern Editor, you can see 'Placeholders:', 'Pattern:' and 'Format:' columns.
The table below lists Pattern Editor elements and explains their functions.
The 'Placeholders:' column
Contains a predefined set of placeholders, the number of which varies depending on the series type.
You can see the full list of available placeholders in the corresponding section of the TextPattern properties.
The 'Format': column
Contains predefined DateTime, Number, Percent, Currency and Special formats.
The 'Pattern:' column
Displays a pattern created by the addition of items from the 'Placeholders:' and 'Format:' columns.
The '>' button

The '>>' button

The Pattern preview

The 'OK' button
Applies a pattern (if the pattern exists in the 'Pattern' column) to the corresponding text pattern property and closes the editor.
The 'Cancel' button
Cancels the operation of applying a pattern to the corresponding text pattern property and closes the editor.
