#6 Errors related the 2d partial graph

[Juan Botía]

There are a number of errors related to the 2d partial graph

-When a 2D graph is shown, the name of agents do not appear in the graph. Only icons appear.

-When the user selects agents that should not appear in the graph, the graph does not updates correctly. Sometimes it shows again the whole graph, including agents not selected to appear. Sometimes no agent appears at all.
