+/** ChartsPanel is a gwt panel, that can show competitor data (e.g. current speed over ground, windward distance to leader) for different races in a chart.
+ * 
+ * When calling the consturcor a chart is created that creates a final amount of series (so the maximum number of competitors cannot be changed in one chart)
+ * which are connected to competitors, when the sailing service returns the data. So {@code seriesID, competitorID and markSeriesID} are linked with the index.
+ * So if u know for example the seriesID-index, you can get the competitor by calling competitorID.get(index).
