@Y_HEADROOM (Riser Headroom)

This macro adds nTop percentage to the biggest riser value and nBottom percentage to the smallest riser values for use in calculating the auto-scale on the Y1-axis. This has the end-result of causing the auto-scale routines to pick larger values for the axis min/max and therefore gives the risers more "headroom" which is useful if data text is crowding the axis min or max lines.
