int y = yCoordinateList.get(verticalGridNum - dataLists.get(k).get(i));

this line crashes, I guess looking for non-existing (negative) y coord

using a BAD workaround, not to make the app crash:

try{ y = yCoordinateList.get(verticalGridNum - dataLists.get(k).get(i)); }catch (IndexOutOfBoundsException boh){ y = 0; }
