我正在使用TreeChart制作指标,如图所示。 但是我有一个问题,我不能使三色渐变到那个指标。这是我的代码
Steema.TeeChart.TChart tChart = new Steema.TeeChart.TChart(this);
tChart.Panel.Transparent = false;
Steema.TeeChart.Styles.Gauges gauges = new Steema.TeeChart.Styles.Gauges(tChart.Chart);
Steema.TeeChart.Drawing.Gradient g = new Steema.TeeChart.Drawing.Gradient(gauges.Chart);
gauges.bBrush.Gradient.Direction = Steema.TeeChart.Drawing.GradientDirection.DiagonalUp;
gauges.bBrush.Gradient.StartColor = System.Drawing.Color.Red;
gauges.bBrush.Gradient.MiddleColor = System.Drawing.Color.Black;
gauges.bBrush.Gradient.EndColor = System.Drawing.Color.Blue;
gauges.bBrush.Gradient.Visible = true;
gauges.Pen.Color = System.Drawing.Color.FromArgb(5,56,73);
gauges.TotalAngle = 180; // circular arc
gauges.RotationAngle = 180; // arc rotation angle
gauges.HandStyle = Steema.TeeChart.Styles.HandStyle.Triangle; // pointer style
gauges.Center.Style = Steema.TeeChart.Styles.PointerStyles.Circle; // SPHERE center circle style
gauges.Center.HorizSize = 5; // center circle level size
gauges.Center.VertSize = 5; // center circle vertical size
gauges.ShowInLegend = false; // display the legend
gauges.HandDistance = 23; // pointer length
//---------------------------------------------------
gauges.Value = 80;
gauges.Minimum = 0; // minimum;
gauges.Maximum = 100; // maximum value
//----------------------------------------------------
gauges.MinorTickDistance = 0;
gauges.Pen.DashWidth = 23;
gauges.Chart.Axes.Left.AxisPen.Width = 65; // brush width;
gauges.Chart.Axes.Left.AxisPen.Color = System.Drawing.Color.Red;
gauges.Chart.Axes.Left.MinorTickCount = 5; // the scale value scale line number
gauges.Chart.Axes.Left.MinorTicks.Length = 10; // the scale value scale line length of
gauges.Chart.Axes.Left.Ticks.Length = 20; // display the value scale line length of
gauges.Chart.Axes.Left.Increment = 3000; // the scale value of interval size
SetContentView(tChart) ;
我还尝试了以下代码行
gauges.CircleGradient.Direction = Steema.TeeChart.Drawing.GradientDirection.DiagonalUp;
gauges.CircleGradient.Visible = true;
gauges.CircleGradient.StartColor = System.Drawing.Color.Green;
gauges.CircleGradient.EndColor = System.Drawing.Color.Red;
gauges.CircleGradient.UseStandardGradient = true;
我希望我能帮忙

您应该使用 Steema.TeeChart.Styles.CircularGauge 而不是 Steema.TeeChart.Styles.Gauges 这是一个更简单的仪表版本。例如,使用下面的代码段,您可以获得与链接中的图像类似的指标:
这与您要找的相似吗?
tChart1.Header.Visible = false;
Steema.TeeChart.Styles.CircularGauge circularGauge1 = new Steema.TeeChart.Styles.CircularGauge(tChart1.Chart);
circularGauge1.Frame.Visible = false;
circularGauge1.FaceBrush.Visible = false;
circularGauge1.DisplayTotalAngle = 180;
circularGauge1.TotalAngle = 180;
circularGauge1.Value = 200;
circularGauge1.Ticks.Visible = false;
circularGauge1.Minimum = 0;
circularGauge1.Maximum = 1000;
circularGauge1.Axis.AxisPen.Visible = false;
circularGauge1.Axis.Increment = 500;
circularGauge1.RedLine.Visible = false;
circularGauge1.GreenLineStartValue = 0;
circularGauge1.GreenLineEndValue = 1000;
circularGauge1.GreenLine.Gradient.Direction = Steema.TeeChart.Drawing.GradientDirection.LeftRight;
circularGauge1.GreenLine.Gradient.UseMiddle = true;
circularGauge1.GreenLine.Gradient.StartColor = Color.Orange;
circularGauge1.GreenLine.Gradient.MiddleColor = Color.Yellow;
circularGauge1.GreenLine.Gradient.EndColor = Color.Green;
circularGauge1.GreenLine.Pen.Visible = false;
