摘要
实时数据线的绘制常用于显示计算机监控系统所监控对象的运行参数。介绍了绘图所使用的坐标系,并实现了坐标的变换,介绍了系统颜色、Pen类和Graphics类,以及绘制直线的方法,给出了一个模拟的绘制实时数据线的实例。
Drawing real-time data lines is widely used in computer monitor systems for displaying runtime parameters of supervised devices.In this paper,coordinates based on computer screen are introduced,and coordinate transformation is realized too;then system color,Pen class and Graphics Class are explained following with the method of drawing lines;finally a example of simulated drawing real-time lines is given.
