Hans,

Thanks for the reply, but I've tried adding "set bars" with out success.
The  "set boxwidth" does control the width of the bars as advertised.
If you read the "set bars" help it actually claims to set the box width
not the tics:

 The `set bars` command controls the tics at the ends of error bars,
 and also the width of the boxes in plot styles candlesticks and
 financebars.

The help candlesticks is a bit ambiguous:
 The width of the rectangle can be controlled by the `set boxwidth` comma=
nd.
 For backwards compatibility with earlier gnuplot versions, when the
 boxwidth parameter has not been set then the width of the candlestick
 rectangle is controlled by `set bars <width>`.

It seems because I do have a set boxwidth, the set bars should produce
ticks, but they don't.

The following script produces the attached plot.  Even though I set the
tick width using "set bars", they don't show up.
