IBubbleChart.NoDataAxisType

Fore Syntax

NoDataAxisType: Integer;

Fore.NET Syntax

NoDataAxisType: Integer;

Description

The NoDataAxisType property determines, which axis is used to check for zero values for displaying of bubble chart bubbles.

Comments

The property is relevant if the ShowBubblesWithNoData property is set to False. The NoDataAxisType property determines a sum of values from the BubbleAxisType enumeration, by which the checking for data for the bubbles is executed.

By default, data existence check is executed along X and Y axis coordinates.

Fore Example

Executing the example requires an express report that contains a bubble chart, a form with the following components:

A button with the Button1 identifier.
EaxBubbleChartBox with the EaxBubbleChartBox1 identifier, the Source parameter must be set up for the UiErAnalyzer1 data source.
UiErAnalyzer with the UiErAnalyzer1 identifier that is a data source for EaxBubbleChartBox1. The Object parameter must be configured to express report, the Active property must be set to True.

Add links to the Chart, Express, Forms system assemblies.

The example is a handler of the OnClick event for the Button1 component.

    Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
    Var
        Bubble: IBubbleChart;
    Begin
        Bubble := UiErAnalyzer1.ErAnalyzer.BubbleChart.Chart;
        Bubble.ShowBubblesWithNoData := False;
        Bubble.NoDataAxisType := BubbleAxisType.X + BubbleAxisType.Y + BubbleAxisType.R;
    End Sub Button1OnClick;

After executing the example the bubble chart of express report does not display the bubbles, which do not contain data on at least one metric: the X, Y axis or radius.
