Is there a work around we could use in the meantime, or should we
attempt to hack trellis.par as per Paul's suggestion (gulp!)? I suppose
that is like asking "Should we attempt to climb Teichelmann?" - it
depends... We have increased the depth of the panel headers, but this
wastes plotting area and the tops of the tees and effs on the upper line
and the bottoms of the gees and whys on the bottom line are still cut
off, so large is the gap between the two lines. And increasing the
panel header depth it doesn't help with y-axis labels - typically the
second line of one label will abut the first line of the next label,
giving a results which is rather like:
where the actual value labels are "Value One", "Value Two" etc and the
"-" are the tick marks. Less than ideal.
Suggestions for interim fixes (other than using abbreviated labels...
we've thought of that) most welcome.
