Hi I'm having incredible difficulty making a simple graph with this fantastic piece of software . This is all I need

X values: 1, 3, and 6

On the y axis, right above each one of the X values, I want the different values.

Let's say House number 1 has had 4, 5, and 6 people in it. So I just need an x value of 1, with three dots above it representing 4 5 and 6.

Thanks
