可以手工绘制任意波形，方便简单。并能实时显示当前坐标值-Arbitrary waveform can be hand-painted, so easy. And real-time displays the current coordinates

可以手工绘制任意波形，并能实时的显示当前的坐标值-Arbitrary waveform can be hand-painted, and real-time display of the current coordinate values

能够实现基本波形（正弦，方波等）的显示功能，有频率和幅度变量的控制。-To achieve the basic waveforms (sine, square, etc.) display, a variable frequency and amplitude control.
