So I'm trying to plot pulse data and my discrete time looks like a mess. I need the time interval to be between pulse n and n-1. I get what is supposed to be a discrete graph but it doesnt look okay to me. The discrete will plot like this...
Can someone explain what's wrong with my code please?

Hi,
Use this command:
stem(data_of_interest) % instead of stem(time, data_of_interest)
Your used command is plotting two data series, viz. time and data_of_interest
You may also need to use xlim command to have better view of your plotted data.
xlim([min(data_of_interest), max(data_of_interest)])

Thank you! So if I use the commands, my plot ends up looking like this, which could proably be due to a lot of noise while I took the data, but is there any way for this to look cleaner or did I mix up the order of the codes?
