[Gnuplot-info] pm3d, colorbox placement and size in Gnuplot 4.0

Hi,

somewhere between Version 3.8j patchlevel 0 and 4.0 there was a change
in the defaults for the placement and size of the colorbox for surface
maps.

In version 3.8j the colorbox had the height of the splot and was nicely
aligned with the top and bottom borders, while it is much smaller and
offset in 4.0.  I digged trough the ChangeLog but did not find any hint
where this might have happened.

Example:

> set size square; set pm3d map; splot sin(x)*cos(y)
> show colorbox
        color box with border, DEFAULT line type is drawn at DEFAULT
        position
        color gradient is VERTICAL in the color box
> show pm3d
        pm3d plotted at BOTTOM
        taking scans direction automatically
        subsequent scans with different nb of pts are flushed from BEGIN
        flushing triangles are not drawn
        clipping: all 4 points of the quadrangle in x,y ranges
        pm3d-hidden3d is off
        pm3d style is implicit
        quadrangle color according to averaged 4 corners

in both versions, except for an additional

        surface is transparent for borders, tics and labels

in the older version, which I guess is irrelevant.  However, the
displayed plot and also a produced postscript file differ.

What am I missing?

Cheers,
