Hey Matt,
Thanks for the quick response;
weather_graph_dir = <nothing>
weather_data_rrd = $Pgm_Root/data/rrd
html_alias_rrd = <mh.ini default>
However, I think this is OK as the mh.ini default is
$config_parms{data_dir}/rrd and the weather_graph_dir defaults to
$config_parms{data_dir}/rrd as well.
weather_data_rrd / $Pgm_Root/data/rrd exists as a directory, I'm thinking
that based on your comment, I think this is my problem as it should exist as
a file.
So I've changed the weather_data_rrd to point to
$Pgm_Root/data/rrd/weather.rrd. It has been created and is now of size
4924000. Now server/bin/weather_graph_zoom.pl works!
Png files are around 36k to 44k -- good size.
Graphs available through URL: Check!
Rrdtransfer.pl contains:

I have no weather_graph_sensor_names config param in either mh.private.ini

What are your settings for weather_graph_dir, weather_data_rrd and
html_alias_rrd? Note that weather_graph_dir is where the graphs are
generated and html_alias_rrd is where the web interface looks for them.
They must point to the same directory.
Does the file pointed to by weather_data_rrd exist?
How big is it? Mine is 4923996 bytes. Yours should be close to this.
Are the .png and .gif files a reasonable size?
Can you view a graph by manually composing a URL?
http://server:port/rrd/filename.png
Paste a copy of your {data_dir}/rrd_transfer.pl file. It contains all of
the relevant parameters used to generate the weather graphs.
To get the indoor/supplemental temperatures to graph, you must define a name
for the sensors. By default, these sensor names are defined on line 192 of
mh/code/common/weather_rrd_update.pl and "activate" all of the sensors.
Perhaps you have overridden the weather_graph_sensor_names parameter
incorrectly. I only have a few sensors, so in my mh.private.ini I have this
line:
weather_graph_sensor_names=intemp => Indoor Temperature,indew => Indoor
Dewpoint,inhumid => Indoor Humidity
