OxyPlot使用经验

OxyPlot C#中的使用经验

类似Surfer的彩虹色标

// 彩虹色标
OxyColor[] rainbowColors = new OxyColor[7];
rainbowColors[0] = OxyColor.FromRgb(139, 0, 0); //darkRed
rainbowColors[1] = OxyColor.FromRgb(255, 0, 0); //red
rainbowColors[2] = OxyColor.FromRgb(255, 255, 0);
rainbowColors[3] = OxyColor.FromRgb(0, 255, 0);
rainbowColors[4] = OxyColor.FromRgb(0, 255, 255);
rainbowColors[5] = OxyColor.FromRgb(0, 0, 255);
rainbowColors[6] = OxyColor.FromRgb(0, 0, 139); //darkBlue

// 反向
// rainbowColors = rainbowColors.Reverse().ToArray();

var numberOfColors = freCount;
var myRainbow = OxyPalette.Interpolate(
    numberOfColors,
    rainbowColors);

图形注解

点注解：

var pointAnnotation = (new PointAnnotation
{
    X = x,
    Y = y,
    Size = 2,
    Fill = OxyColors.Blue,
    // Text = text
});

this.plotView1.Model.Annotations.Add(pointAnnotation);

折线注解：

// 线的情况
PolylineAnnotation polylineAnnotation = new PolylineAnnotation { };

listGridPoint.ForEach(gridPoint =>
{
    var x = gridPoint.x;
    var y = gridPoint.y;

    DataPoint dp = new DataPoint(x, y);

    polylineAnnotation.Points.Add(dp);
});

this.plotView1.Model.Annotations.Add(polylineAnnotation);
