Hi
This patch does add the MAX graph (AREA) for the Service graphs. And the Max numerical value is as well taken from the MAX RRD value instead of AVERAGE.
When scaling to larger amount of time, displaying like today the average only makes all spikes disappear, and the Max value does not make much sense.
I also added a color choice to *pinkify* the "Loss" graphs.
Exemple with HTTP graphs polling google:

* Added check_load.inc.php.
* Combined load graphs. Removed extra backslashes from all graphs. Escaped backslash in mysql file.
* Added a note about local only service checks to the docs.
Graphs that were using `file_exists()` to check for the presence of RRD
files now use `rrdtool_check_rrd_exists()` instead. This is a fix for
distributed poller configurations that are running `rrdcached` on a
different host.
Use data_update instead of rrd_update/rrd_create and influx_update
Centralize rrd file check so we can check against a remote rrdcached server too
Use rrd_name() to generate rrd file names
