The problem
When grouping the results (i.e., in Charts lingo, having more than one series) and some series don't have all the data points, the output will be wrong, since values per series will just be added sequentially from the "right", through the following line (which doesn't take the "label key" into account at all):
$chart[$series_key]['#data'][] = $value;
An example
You want to show a column chart of the GPD of two countries, A and B, for the years 2012–2014, but country B hasn't reported a value for the year 2013:
Country | Year | GPD
---------------------
A | 2012 | 8 T$
A | 2013 | 9 T$
A | 2014 | 10 T$
B | 2012 | 3 T$
B | 2014 | 5 T$
This will lead to the following output:
As you can see, the value for B/2014 ends up as the 2013 value instead.
