Same thing. Now I don't have group header bars seperating my layers, but
all the layers still show up and when I click on a layer that has scale-specific
classes, the symbols for all scales still show up. By the way, I'm on Mapserver
3.6.1 and here's the page to go to if you want to see what I'm talking about:<br>
<br>
<a class="moz-txt-link-freetext" href="http://cnrit.tamu.edu/maps/map_init.html">http://cnrit.tamu.edu/maps/map_init.html</a><br>
<br>
Click on the very last button on that page (the one that says "FRAMES VERSION"
on it). When the map shows up, expand the "Regional" folder on the left-hand
side to display those layers. The one that I'm working on right now is called
"Parima Survey Households". Click on that layer to load it into the map,
then you'll see the various symbols I'm referring to show up in the legend.
I represent the Parima households with red triangle symbols and I have different
sized triangles depending on how far zoomed in you are so that they are small
at a high scale and larger as you zoom in...but I don't want all versions
of that symbol to show up in my legend all the time...just the one that's
in scale.<br>
<br>
Thanks again!<br>

Try this. Take out the leg_group_html section, and the leg_layer_html section,
leaving only the leg_class_html section. Take them out entirely - don't

Gladly. Here is my legend code:<br>
<br>
[leg_group_html]<br>
<tr><br>
<td colspan=3 bgcolor=#cccccc><b>[leg_group_name]</b></td><br>
</tr><br>
[/leg_group_html]<br>
<br>
[leg_layer_html]<br>
[/leg_layer_html]<br>
<br>
[leg_class_html]<br>
<tr><br>
<td width=15> </td><br>
<td><br>
<img src="[leg_icon width=15 height=15]" width=15 height=15><br>
</td><br>
<td><br>
[leg_class_name]<br>
</td><br>
</tr><br>
[/leg_class_html]<br>
<br>
<br>
However, it does not work as you say (and as the documentation on the
web page says!). Layers that are "off" do not show up (that's as expected
and what I want), that's fine, but layers that are out of SCALE DO show
up, and that's not as expected and that's not as the documentation states
and that's NOT what I want. For example, I have a layer called Ethiopia_Rivers...here's
what it looks like:<br>
<br>
LAYER<br>
NAME "Ethiopia_Rivers"<br>
TYPE LINE<br>
STATUS off<br>
GROUP Ethiopia<br>
DATA "ethiopia_rivers"<br>
HEADER 'ethiopia_rivers.shp_header.html'<br>
CLASS<br>
MAXSCALE 8710165<br>
Name 'Ethiopia Rivers'<br>
COLOR 102 204 255<br>
TEMPLATE ethiopia_rivers.shp_query.html<br>
END # CLASS<br>
END # LAYER<br>
<br>
Now, when I'm viewing my map at full extent, my scale factor is 1:<font size="3"><b>
20136789</b></font>, therefore if I click on the Ethiopia_Rivers layer
at that zoom level, nothing shows up in the map. This is the exact behavior
that I would expect...I'm out of scale for that layer, so it doesn't show
up in the map until I zoom in. The PROBLEM, however, is that the "Ethiopia
Rivers" icon and label pop up in my legend...this is counter-intuitive,
contrary to the documented behavior of Mapserver, and just flat-out frustrating!
If the layer is not showing up in my map (because it's out of scale),
then it should NOT be in my legend either. Grrrr!!! Pardon me for sounding
bitter...I'm not lashing out at you, I'm very grateful for your help,
I'm just frustrated at Mapserver.<br>
<br>
Thanks!<br>
