微机界面动态图的坐标变换及稳定性设计

基于微机原理中汇编语言程序执行的实时性特点,设计了在微机显示器屏幕上画直角坐标系下的动态变化图.采用数学变换的形式,克服了微机显示器屏幕的坐标与直角坐标系不一致的问题,同时解决了换页时出现的图形变乱问题.以工程实际为例,在显示器上画出实时的跟踪风速随时间变化的正弦曲线图.

Design of Coordinate Transformation and Stability of Dynamic Chart on Interface of Computer

Basing on the well-timed characteristics that the assemble language has when executing. A dynamic diversification chart in rectangular coordinate is designed for display screen. We adopted mathematical transform, so that the problem that screen coordinate of computer is different from rectangular coordinate is overcome. At the same time, the problem that the chart becomes confused has been solved. Taking an engineering example, a sinusoidal graph showing how the wind speed changes with time has been plotted on the screen of computer.
