You posted the same in three different places already. Once is enough!
Instead, I would recommend to refine the question. A waveform chart has nothing to do with pulse rate, it is just a display that can even show nothing. What matters is the data displayed on it. You simply need to provide significantly more detail.
What does the chart display? What is the time spacing of the data points?

i have got an output waveform (X-axis as amplitude and Y-axis as time )as shown in the attachment
The attachment is a picture of the block diagram and does not show us any typical waveform obtained by your measurement. We need to see how the measured data looks like (noise, shape, etc.)
Since you are only getting a single scalar with every iteration, maybe one of the pbypt tools would work (e.g. Peak Detector PtByPt VI or similar).
Sorry, I don't have the vision tools, but your data looks pretty clean, basically a single frequency with a huge DC components that you probably want to subtract. Simplest would be to save the time in a shift register whenever you get a peak and look at the time difference of successive peaks, then apply some simple math. You might need some filtering and other cleanup. Still, seems pretty trivial.
Currently, we can only look at your data from a small image, do you have some real and typical data? Can you record and store a typical time trace over e.g. a minute and attach it so we can play?
What is the loop rate?

can you attach what you have told to the block diagram using shift registes
Not before I can test with some typical data. You have not answered any of my questions.
