graphs retain values

[sridps]

Hallo,

i am having trouble in clearing my graphs in the attachment . I tried invoking property node and reinitialised to default and also tried the clear indicators option under Vi properties . Both these options clear the graphs when i run the program,but when the values are plotted they continue from the previous iteration.

Kindly help with a solution .

Thanks and best regards,

Try initializing the shift registers in your loop. If you don't initialize the shift register, they retain their values for as long as the VI is in memory.

Hallo,

Thanks a lot for your reply.

I tried initialising the shift registers to 0 and there was no graph at all .

Thanks and best regards ,

Hi sridps,

your loop only runs once as you wired a "1" to the iteration count terminal. So your shift register will hold just one value when you initialize them with empty arrays…

You should

- remove local variables and use more wire

- think about state machines instead of giant sequence structures

- only initialize the shift registers once at start of your measurement

Hallo, 

Thanks for your reply .

There is an outer while loop which makes the actual iteration and i actually collect the data the required number of times. For some reason it does not collect data multiple times without a for loop and it doesnt matter whether i give the for loop number as 1 or 10 . I still get the same result .

I have no experience with state machines . Maybe i should try them . But i have no idea why my graphs behave like this now .

Thanks and best regards

It is expected behavior for a shift register to retain data between iterations. You don't show the main VI but that is probably where you want it. Your code makes very little sense.

Which VI? Where?

(In case of difficulties in uploading VIs you should read this thread…)
