clear xy graph at call

[jerryj]

Hi, i am brandnew. At least at using labview. I am using it for a month now. I have a question.

I have a multiple stripchart with different inputs. All these inputs are just using the Y values of the input signals.

I made an xy graph where i can choose wich signal i want to see via an enumerator (case value). say signal 1-8. this all works ok.

But when i choose an signal say nr 3 or so. it does not clear out the last signal wich was on the xy graph.

While measuring, everytime when i choose a signal the xy-graph should be cleared and start fresh with the chosen signal.

How do i do this? (i tried different things like shifts-registers and so on)

Please help, thanks a lot.

If you want a quick solution, post a simplified version of your vi, using short Y values arrays to simulate your different acquisitions. Somebody will fix that with you.

Hi, thanks for replying.

I mean something maybe quite simple as this. please see attachement. i use labview 6.0.2

it simply has to give ture one time and the rest of the time false, but i can't figure it out, also tried with shift registers.

Thanks for all the help.
