Wrong measurement type of x axis and Peak Plotting issue

[zUko_Oof]

Hi all, I am a student learning how to use labVIEW for my project. The project that I am doing is based on a microphone Adafruit MAX9814 to pick heartbeat sounds and display it 

The problem I am having is such that the x-axis of initial recording is based on time(s). However after the process of writing and read the file, the x axis for waveform after Read from Measurement File was not based on time anymore. 

I would like some help to edit the program such that the x-axis of both is waveform is based on time(s).

The second problem I have is such that white line that was meant to be on my peak of my data recorded was not lined up well. 

Thanks in advanceBlock Diagram1Block Diagram 2Front panel

In Simpe save the file with Time stamp and use the same value for displaying in graph.

Hello Mr Palanivel Thiruvenkadam

I am sorry but can you re elaborate what Simpe means?

Thanks !

Hi zUko,

your data file contains 2 signals and you try to analyze the first signal. (Unfortunately the first signal seems to be the time axis…)

All is working as YOU have programmed it!

Why don't you try to analyze the 2nd signal?

On the axis problem: Did you read the help for this Wavelet function? Did you notice it's output datatype? It does NOT output a waveform!

Hello GerdW,

Thanks for replying. 

Sorry for questioning quite a lot. How do you see that my data file has contained 2 signals? Is it that my supposed time axis was placed as a signal as the white line instead of an axis?

On the help issue, do you use context help?

Thanks in advance!

Hi zUko,

How do you see that my data file has contained 2 signals?

Open the data file with a simple text editor like Notepad…

Is it that my supposed time axis was placed as a signal as the white line instead of an axis?

Yes, it seems so. Probably because of YOUR expressVI configurations…

On the help issue, do you use context help?

Not so often nowadays, most often to check the datatype of (cluster) wires…
