功能描述：这是一个示波器波形显示控件，能够完成类似于示波器的功能。最多可以同时显示8个通道的数据波形，可以动态切换显示通道。缩放xy轴，弹出半透明窗口显示坐标，y轴方向平移波形等功能。 操作使用键盘快捷键，操作说明见readme.txt，目前按键焦点的得到有点问题，要点击开始后在示波器上鼠标左键单击一下，然后按一下上箭头键，才可以响应按键指令，有高手知道怎么改进希望告诉作者：xiang57@163.com(Functional Description: This is an oscilloscope waveform display control, able to complete similar oscilloscope function. At the same time show up to eight channels of waveform data can be displayed dynamically switch channels. Zoom xy axis, translucent pop-up window displays the coordinates, y-axis direction of translational wave functions. Operation of the use of keyboard shortcuts, operating instructions see readme.txt, the current key focus has been a problem, it is necessary to click on the oscilloscope after the beginning click the left mouse button, and then click on the arrow keys, before they can respond to key commands, has a master know how to tell the authors hope to improve: xiang57@163.com)
