No, what version of librenms on the one that working with the graphs
The intresting thing is , if I move the png ,html and conf file from old server to new server
In a new server the floating graph is working for this specific graph
I fixed the floating graph, there is a value on the Map properties , called default width, set it to 4, and it should give the floating graph
Awesome!! 
I will try it on mine too -
If you can truly make this happen more than once, please report it as a bug here: https://github.com/howardjones/network-weathermap/issues
(this sounds like it it really isn’t what fixed your problem - HTMLSTYLE overlib is the solution)
You can also search for the WMWARN error codes and in most cases get an idea of the solution - that’s why they were added

I am using ./IPaddress/ as the source in my conf files and I am getting errors that the file does not exist.
conf line
LINK 10.0.25.2:GigabitEthernet3/1/2-10.0.18.1:GigabitEthernet1/1
INFOURL /graphs/type=port_bits/id=3363/

TARGET ./10.0.25.2/port-id3363.rrd:INOCTETS:OUTOCTETS

The file is located in weathermap/rrd
-rw-rw-r-- 1 librenms librenms 1849688 Mar 26 15:41 port-id3363.rrd
My rrdtool is located in /usr/bin/
My error is
Target ./10.0.25.2/port-id3482.rrd doesn’t exist. Is it a file? [WMRRD06]
Any ideas??
[root@netcore Weathermap]# ./weathermap.php --config configs/cg.conf --output output/cg.png --htmloutput output/cg.html
PHP Notice: Undefined property: WeatherMap::$basehref in /opt/librenms/html/plugins/Weathermap/weathermap.php on line 287
It tells you have an error on line 287.
Hit same issue. Fixed it by adding to the .conf file the following:
HTMLSTYLE overlib
In the map properties it had been set too, but only duplicating it inside the config file helped.
Hope it might be helpful
This helped me.
./weathermap.php --config configs/prod_mpls.conf --output output/mymap.png --htmloutput output/mymap.html --base-href /opt/librenms/html/plugins/Weathermap/
notice I put in the --base-href /opt/librenms/html/plugins/Weathermap/
That got rid of my line 287 error.
