Tom,
I imagine you are refering to bug 653. The behaviour is as follows:
If a GetLegendgraphic request does not provide a RULE parameter then all the
layers are set to status OFF except the layer specified in the LAYER request
parameter. The legend is drawn for this particular LAYER and if the SCALE=20
parameter is also provided
some extra calculations have to be performed to determine whether the=20
legend should be drawn at the provided SCALE because the LAYER could have=20
MINSCALE/MAXSCALE set in the mapfile
In some cases we would like to have as part of the legend also the=20
name/description of the LAYER (see bug 732). But this feature is not yet=20
implemented.
Cheers,
Valik

I imagine you are refering to bug 653. The behaviour is as
follows:<br><br>

all the
layers are set to status OFF except the layer specified in the LAYER
request
parameter. The legend is drawn for this particular LAYER and if the SCALE
parameter is also provided

MINSCALE/MAXSCALE set in the mapfile

I thought the "multiple CLASS" GetLegendGraphic bug took care
of this,<br>
i.e. if one CLASS, then don't print title, if multiple CLASSES,
prints<br>
CLASS NAME as text.<br><br>
