能够显示正弦-方波-三角波,并且能够选择性显示几种波形

产生正玄波，方波；三角波 采用时间的画法；根据时间绘出波形-Generate positive mysterious wave, square wave triangle wave using the time of painting plotted according to the time waveform

此程序包含了方波、三角波、正弦波等等的绘制，还有随机长生折线波形和自定义绘制波形等等。-This program contains a square wave, triangle wave, sine wave, and so the drawing, there is a line longevity random draw waveforms and custom waveforms and so on.
