Example

Executing the example requires a form, the Button component with the Button1 identifier on this form, the ChartBox component with the ChartBox1 identifier and the UiErAnalyzer component with the UiErAnalyzer1 identifier. Specify the UiErAnalyzer1 data source for the ChartBox1 component.

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

Add a link to the Drawing system assembly.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Chart: IChart;
    ChartAxis: IChartAxis;
    MinorLinePen, MinorTickPen: IGxPen;
Begin
    Chart := ChartBox1.Chart;
    ChartAxis := Chart.AxisY;
    ChartAxis.DisplayMinorGrid := True;
    ChartAxis.MinorLinePen := New GxPen.CreateSolid(GxColor.FromName("Red"),0.1);
    ChartAxis.MinorTick:= True;
    ChartAxis.MinorTickPen := New GxPen.CreateSolid(GxColor.FromName("Green"),2.1);
End Sub Button1OnClick;

Clicking the button enables displaying of minor gridlines and grid tick marks with determined settings of color and line width.
