So the problem is that chart shows different distansies between the bars on left(Link2) and right(Link1) sides of itself.. It's somehow squeezed up a part of itself. Because of that it also represent the lines abnormally. It seems like they r broken in "transition point", although they are really straight line.. You can recheck it by reducing the range of chart. In some point it becomes represent correct distances between bars and line becomes straight as it should be. Please respond if anyone know how to fix this.. Would appreciate any answers or suggestions. Thanx
