DisplayBorder: Boolean;
DisplayBorder: Boolean;
The DisplayBorder property determines whether chart tooltips have a border.
Available values:
True. Default. Chart tooltip border is displayed.
False. Chart tooltip border is not displayed.
To execute the example, on the form place the Button, ChartBox and UiErAnalyzer components (in the Fore.NET example use the ChartBoxNet and UiErAnalyzerNet components) named BUTTON1, BUTTON2, CHARTBOX1/CHARTBOXNET1 and UIERANALYZER1/UIERANALYZERNET1 respectively. In the ChartBox/ChartBoxNet component set the Source/UiSource property to UiErAnalyzer1/UiErAnalyzerNet1. In the Button1 component set the Text property to Hide Border value, in the Button2 component set the Show Border value. In the UiErAnalyzer/UiErAnalyzerNet component set the Active component to True. There should be an express report specified as the Object property for the UiErAnalyzer/UiErAnalyzerNet component.
