Evolution Graph

I am trying to create a graph of population evolution for different cities, but I don't know how to create it the way I have structured the data.
I have two tables a first table (table1) with the cities and the information of the different apartments they have for sale (there is more than one apartment for each city).
On the other hand, (table2), my table of population evolution by city, in which my first column is the name of the city and then I have a column for each year of study, in total I have 10 years. This table has 11 columns.
I have created a relationship of several to 1 between table1 and table2. 

This relationship must be maintained, because from table1 I have to be able to filter information from table2.

My goal is to create the evolution graph from table 2, showing each year and the population of this year.
This is an image of table1

This is an image of table 2

And this is an image of the model

My goal is to create something like this

Thanks in advance
