+Plot a tick mark (a vertical line) for each value of vname that is non-zero and not *UNKNOWN*. The fraction argument specifies the length of the tick mark as a fraction of the y-axis; the default value is 0.1 (10% of the axis). Note that the color specification is not optional. The TICK marks normaly start at the lower edge of the graphing area. If the fraction is negative they start at the upper border of the graphing area.
