BUGFIX: Fixed Bug created by extracting different rows for each series (to fix the big not connecting lines at edges). Now all calls to the getLeftBoundry method are done with the correct set index resulting in a correct behaviour now.
BUGFIX: Added "this." to the  boundryIds_ calls
TEST: Added test to verify that the left boundry works now.
BUGFIX: Fixed bug using the idxToRow_ function instead of directly taking the row from the point. Also the idxToRow_ method has been completely removed based on Dans comment, that it is unneeded.
Fixed wrong space usage in if clauses.
