How to pass cursor postion to indicators?

[Jiabei]

Hi, I am using a cursor to pick the maximum amplitude from a fft result. Then I want to update the cursor location at an amplitude spectrum on indicators. While the values I passed is a cluster of two elements, the container is a tpye of single double. Can anyone take a look at my Vi?

BTW, the string I used is the time signal.  The sampling rate is 100000 samples / second, the number of samples is 1000, so the nyquist frequency is 50000Hz. But Labview gave out a different value, why?

Thanks in advance.

Sorry, I don't know what you mean by " passed is a cluster of two elements, the container is a tpye of single double". Are you looking for an "unbundle" operation?

If you want to show the cursor positions in plain indicators when you move it, you could do something like in the attached modification. See if this suits your purpose. 🙂

Also, one event structure is probably enough. Simply add more event cases.
