ISpeedometerFilledBar.EndRadius

Syntax

EndRadius: Double;

Description

The EndRadius property determines the final limiting radius of the bar.

Comments

It is a relative value (the ratio of the current radius to the distance from the inner scale border to the centre of the sector, which circumscribes the scale). The value of the radius is set in the range [0,1].

Example

Executing the example requires a form with the Button1 button and the SpeedometerBox component named SpeedometerBox1.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);

Var

s: ISpeedometer;

v: ISpeedometerView;

ScaleView: ISpeedometerScaleView;

FilledBar: ISpeedometerFilledBar;

Bar, Bar1: ISpeedometerBar;

Begin

s := SpeedometerBox1.Speedometer;

v := s.View;

s.BeginUpdate;

ScaleView := s.View.ScaleViews.Item(0);

FilledBar := ScaleView.FilledBar;

FilledBar.StartRadius := 0.1;

FilledBar.EndRadius := 0.9;

FilledBar.Bars.Count := 2;

Bar := FilledBar.Bars.Item(0);

Bar1 := FilledBar.Bars.Item(1);

Bar.StartColor := GxColor.FromName("Blue");

Bar.EndColor := GxColor.FromName("Green");

Bar.Part := 0.7;

Bar1.StartColor := GxColor.FromName("Green");

Bar1.EndColor := GxColor.FromName("Red");

Bar1.Part := 0.3;

s.EndUpdate;

End Sub Button1OnClick;

After executing the example, on clicking the button, the formatting of speedometer color interval bar displayed in the SpeedometerBox1 component is changed. The interval bar is divided into two segments. Start and end color of gradient are determined for every segment. The first segment takes 70%, the second one - 30% of interval bar. Initial and final bar radii are set to 0.1 and 0.9 respectively.
