Can you descript it with more details?

Do you mean you open the same wav file for twice, but the graph control shows different?

yes, thanks for your reply, here is the problem labview7:

 

1. mermery of grahic:  final2.vi

 

 when i play the same file wav with the choix of differents filters, the sound output is ok, the graphic chang also, but when i choose the same filter, the graphics are differents. 

 

2. continuous graphic: essayer.vi

 

in fact, i want to show the wav file, continuous like in recording. so i put the graphic in the while, but it show the last data, just the time is continuous, the chart  stays. maybe the data in the file is like a table, so it show in the same time, so shoud i need use some fonctions to make that?

 

thanks

In your attached essayer.vi, I found that, in the play button value change event case, you place the part below in:

In my opinion, what you want to do is to diaplay the  wav file data continously, am I right?

 

But if the output of Time Elapse.vi is Flase, the indicator called Affichage 2 will receives the same data, each time the while loop runs, it displays the same data as if "the chart  stays".

 

I think you should change your VI to make it more readable.
