Good idea to add the end date/time to graphs larger than default (like when you 
zoom an individual graph to save it).  I think we can do this in graph.php.  It 
is not needed on default graphs since you see the time on the HTML page and 
don't need this duplicated on all the graphs.

>graph was produced :-). But if clutter doesn't matter, why not do both? I

Where do you draw the line?  I want to know average value of all metrics 
plotted, not just CPU or load.  Why is memory less important?

If we put all the numbers in text on the left, then they have to be labeled, 
duplicating the labels already in the graph legends.  Since the graphs already 
have color-coded legend labels, it seems logical to add the mean values right 
there where the user is already looking.  In some cases, this adds one text 
line (14 pixels?) to the image.  In other cases it adds none.

Either way, the fact that I can instantly see the average value of all the 
colored squiggly lines and areas, instead of having to eyeball a guess against 
the Y axis, makes up for the 14 pixels lost in the plotting area.  We could 
even add 14 pixels to default graphs if that is a concern.  It would be harder 
to go looking for the corresponding number in the text to the left of all the 
graphs.

>do not believe that the additional overhead is such a problem.

True.  But it seems there has been some questions as to whether the 
calculations are being done correctly, and where the data comes from (load or 
CPU).  That's why I think it is cleaner to leave only the current load data in 
the text, and add all average numbers to the graph images where the source is 
obvious.
