[Mapserver-users] Legend templates, classes and lines...

[Steve Lime]

J.F. - I verified that the 3 files are indeed the same. I'll paste the
layer definition below but it's pretty straight forward. Only thing I
can think of is a stuck loop counter someplace. I'll try using a STYLE
instead of just a COLOR and see if that helps.

Steve,

Hmmm, as you know we use HTML legends extensively, and as of yet I've
never
heard of anybody running into this kind of problem in our shop.

It's a pretty simple legend template too, not much room for error.

Also the page output suggests MapServer DID indeed render 3 different
icons
for each of the classes.

I would try looking at the caching features of MapServer ... Maybe it's
not
overwriting previous icons? Clear the temp directory or something like
that?

Maybe you could send the mapfile along to see if there's anything weird
in
there? Otherwise, I'm afraid you'll have to look in the code!

Good luck!

J.F.

Hi Folks: I'm using 4.0 and wondered if anyone else has run into
problems with legend templates with LINE layers and multiple classes.
Check out the following URL:

 
http://maps.dnr.state.mn.us/cgi-bin/mapserv40?mapserv=http%3A//maps.dnr.stat

e.mn.us/cgi-bin/mapserv40&map_status=on&mapsize=800+750&map=LANDVIEW_HERITAG
E_MAPFILE&template=/usr/local/www/docs/landview/heritage/templates/print.htm
l&mapext=316287.17433148284+4891207.862044461+342298.221100423+4910705.97065
5294&layers=mnrrpln3+mnnpcpy3+mnsbspy3+lakes+ctybdln2+doq03im4

It's a "print" layout and uses the legend template functionality. The
problem is that the line legend for the "Railroad Rights-of-Way
Praries"
ain't right. The 3 classes should be red, yellow and orange (as in the
map) and not all red. The polygon layer below it ("Sites of
Biodiversity
Significance") works as expected. Before I run to the source code I
want
to make sure I'm not doing anything stupid. The legend template is
included below.
