IChartGraphArea.AutoMargin

Syntax

AutoMargin: Boolean;

Description

The AutoMargin property determines values of automatic margins for the chart plot area.

Comments

The AutoMargin property is set to True by default. The margin values for the chart objects are 1 mm.

This property is saved together with the chart. If an object from the previous version is loaded, the AutoMargin and Margin properties are set by default.

Example

Executing the example requires a form with a button named Button1 on the form, the ChartBox component and the UiChart component that is a data source.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    c: IChart;
Begin
    c:= UiChart1.Chart;
    c.GraphArea.Margin:= New GxRectF.Create(0, 0, 0, 0);
    c.GraphArea.AutoMargin:= False;
End Sub Button1OnClick;

Clicking the Button1 button sets the distance from the plot area (including labels and axes) to the chart edges that is equal to zero.
