Syntax

Example

Executing the example requires a form, the Button component with the Button1 identifier on the form, the ChartBox component with the ChartBox1 identifier and the UiErAnalyzer component with the UiErAnalyzer1 identifier, which is used as a data source for the ChartBox1 component. Specify the express report saved on the chart sheet as a data source for the UiErAnalyzer1 component.

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

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Chart: IChart;
    ChartAxis: IChartAxis;
Begin
    Chart := ChartBox1.Chart;
    ChartAxis := Chart.AxisY;
    ChartAxis.StepMode := ChartAxisStepMode.FixedStep;
    ChartAxis.StepValue := 10000;
End Sub Button1OnClick;

After executing the example tick mark intervals equal to 10000 are displayed on the Y axis.
