One way is to use Shift Register/ Feeback Node to build array for graph plotting purposes.
Attached a basic array building example with shift register...
PS: be aware of dealing with large amount of data as array is getting larger over time.
thank you 。
如果我没有理解错的话的。您这个graph_build.vi只是实现了完整显示了从t=0时刻到t的随机量随时间变化的关系。而我期望的是两个变量的相关变化啊。如力与变形之间的关系,相关关系很重要,一般的混凝土材料都是弹性到塑弹性再到塑性,要通过实验体现这个关系。谢谢
Hi, first of all, the example is for your reference (based on your initial question) and for modification to suit your needs... Secondly, I am sorry but I may not able to fully understand some of the technical terms that you used in Chinese Language.
We are here to help and guide but not to, every time, provide exact solution.
感谢 ian fung和游泳的鱼,把你们的思路结合在一起,我做到了可以“实时显示位移和荷载相关曲线”,详见graph_build_1.vi,XY图表中的点会随时间变化而及时添加,点的坐标分别为两个随机量(其X轴 非时间量time),而历史的点会被保留。目前存在的问题就是随着时间的延长,实时性很难保证,似乎每次都要重新绘制所有点。不管怎样,在实时性要求不高的实验中这就足够了。
