曲线监控模块用的很少,主要就是用来观察某个设备的实时采集的数据和历史采集的数据,可以回放数据,在右侧可以选择对应的通信端口和控制器,然后选择指定的探测器进行观察,从选择的时候开始计时,每个数据都对应一个数据点,至于采集间隔,这个在端口管理中设定的,一般来说都是1秒钟采集一次。
显示曲线图表控件,个人强烈推荐开源的qcustomplot或者qwt,Qt5.7以后集成了qchart模块也有曲线控件,个人觉得用法还是不够友好,而且很多人反映大数据量基本上歇菜,只能做一些小数据量的展示,我看过qchart模块的完整源码,写的不是很好,也许后期改进了不少,还是Qt4时代若基亚品质保证,代码质量都是杠杠的,可惜若基亚把Qt卖了。
