labview实现多条曲线的叠加，非常好用。比较好的控件-The labview achieve curve superimposed, very easy to use. Better control

自己设计的labview控件（解压后请看example文件夹的example.vi）,能在曲线上跟随鼠标的位置显示当前点的坐标值。-Labview control of their own design (see example after extracting the folder example.vi), can be followed on the curve shows the current location of the mouse coordinates of the point

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 th
