在波形Graph显件上用两种不同颜色显示一条正弦曲线和一条余弦曲线，每

条曲线长度为128个点，其中正弦曲线的x0 =0，△x=1；余弦曲线的x0 =2，

△x=5。并利用属性节点通过前面板控件改变每条曲线的颜色。-On the waveform Graph show piece in two different color shows a sine curve and a cosine curve, eachCurve length is 128 points, in which the sinusoidal x0 = 0, delta x = 1 Cosine curve x0 = 2,Delta x = 5.And use the attribute node through the front panel controls changes the color of the each curve.
