If true, automated tick placement will be independent of the physical extent of the axis. Tick placement will look good for charts of typical size (say physical dimensions of 640x480). If you want to produce the same chart on two graphics surfaces of different sizes [eg Windows.Forms control and printer], then you will want to set this property to true. If false [default], the number of ticks and their placement will be optimally calculated to look the best for the given axis extent. This is very useful if you are creating a cart with particularly small or large physical dimensions.
