Size size,
) {
var xAddition = -graph.focusPoint.x;
var yAddition = -graph.focusPoint.y;
addObject(GraphLine(
color: graph.axesColor,
startOffset: Offset(-(size.width / 2 + xAddition.abs()), 0),
endOffset: Offset(size.width / 2 - xAddition, 0),
lineWidth: graph.axesWidth));
addObject(GraphLine(
lineWidth: graph.axesWidth,
color: graph.axesColor,
startOffset: Offset(0, -(size.height / 2 + yAddition.abs())),
endOffset: Offset(0, size.height / 2 + yAddition.abs())));
