More Detailed/Waved Line Chart

I am trying to create a line chart using Google Charts Library, what I tried so far is: I added 2 columns and 50 rows and what I get is something like this: Count is generated randomly on every row

What I want is something like this: which has more waves, I tried to add more rows like around 500 but it still looks like the chart above.

So what should I do? is it because I generate random numbers?
