xy图如何实现刷新

[abbxj]

请问高手:  XY图如何能实现刷新？！急, 能写个例子吗？！

It will automatically refresh whenever you have new data.

You can also use invoke node to force it to redraw.

多谢！

第二次循环时，实时的XY曲线，会叠加在第一次的循环中！

REDRAW 不知在那里，能给我个例子吗？急  xiaojie.xu@jci.com

Usually this won't happen.  You must be appending your 2nd loop data to the 1st loop.

Post your VI and a screen shot, so we can see the problem.

这是主VI截图

Looks like each iteration you will get a data point => build into an array => display the array.

Please give more detail.  I don't understand your problem.  The code looks ok.
