Dear xyq102296,


this express VI is rather new, please find an example based on the waveform attribute function (saved in 8.6); the express VI in question is based on these VI's.


Please let me know if you have any further questions,

the block in the is set waveform attribute which I already have in the labview 8.6 , in labview 2009, it seems that I can change the name through a block named "set dynamic attribute"

I have installed the labview 2009 evalution version , so I have found the "Set Dynamic Attribute" which can change the name of title , but there comes up a new problem to me.

Before the "Set Dynamic Attribute" block, I use the "change to dynamic data"block , which inside it , I set the time start from now, and I have a for-loop outside , I can write down the data and the time interval between each loop, but when I connect the Set Dynamic Attribute to change the first column "X_Value Untitled" into "time " , after I done this , time interval changes to zero, when I change other column title and leave the first column unchanged , the loop works great and still shows me the data and the time interval I want.

can you solve it ?
