## 具有X和Y数据的SignalConst

SignalXYConst是一种速度优化图，用于显示具有升序不均匀间隔位置（X）的值（Y）。如果数据间隔均匀，则Signal和SignalConst会更快。

``````var plt = new ScottPlot.Plot(600, 400);

// generate random, unevenly-spaced data
Random rand = new Random(0);
int pointCount = 100_000;
double[] ys = new double[pointCount];
double[] xs = new double[pointCount];
for (int i = 1; i < ys.Length; i++)
{
ys[i] = ys[i - 1] + rand.NextDouble() - .5;
xs[i] = xs[i - 1] + rand.NextDouble();
}

plt.SaveFig("signalxyconst_quickstart.png");
``````

## xs和ys的不同数据类型

``````var plt = new ScottPlot.Plot(600, 400);

Random rand = new Random(0);
int pointCount = 1_000_000;
double[] sine = DataGen.Sin(pointCount, 3);
double[] noise = DataGen.RandomNormal(rand, pointCount, 0, 0.5);
float[] ys = sine.Zip(noise, (s, n) => s + n).Select(x => (float)x).ToArray();
int[] xs = Enumerable.Range(0, pointCount)
.Select(x => (int)x)
.Select(x => x > 500_000 ? x + 1_000_000 : x)
.Select(x => x > 200_000 ? x + 100_000 : x)
.ToArray();

plt.SaveFig("signalxyconst_types.png");

## 信号常数阶跃模式

``````var plt = new ScottPlot.Plot(600, 400);

// generate random, unevenly-spaced data
Random rand = new Random(0);
int pointCount = 100_000;
double[] ys = new double[pointCount];
double[] xs = new double[pointCount];
for (int i = 1; i < ys.Length; i++)
{
ys[i] = ys[i - 1] + rand.NextDouble() - .5;
xs[i] = xs[i - 1] + rand.NextDouble();
}
