| AppearanceObject | An object that contains appearance settings. |
Remarks
You can print the chart legend and additional information in page footers.
Legend
Enable the PrintLegend property to display a chart legend in page footers.
The AppearancePrint property provides access to appearance settings used to print the control. You can use the following properties to specify how to print the legend:
- Legend — appearance settings used to print the chart legend.
LegendItem— appearance settings used to print items in the chart legend.
Ensure that the UsePrintStyles property is set to true (the default value) to enable these settings.
Page Information
Enable the PrintPageInfo property to display additional information in page footers. The default footer contains the current date, page number, and the total number of pages.
Use the PageInfoType property to specify the type of information that should be displayed. The PageInfoFormat property allows you to apply a custom format to this information. Use the {0} and {1} placeholders to insert a specific portion of information into the format. The passed content depends on the type of information. For example, if PageInfoType is set to NumberOfTotal, {0} is replaced with the page number, and {1} is replaced with the total number of pages.
You can also use the PageInfoCaption property to display a custom caption in the page footers.
The AppearancePrint property provides access to the PageInfo and PageInfoCaption properties that specify appearance settings used to print page information.
