<br><font size=2 face="sans-serif">Hi everybody!</font>
<br>
<br><font size=2 face="sans-serif">I have set up a little demo for something
I have hacked together since yesterday: RRD - Web 2.0 style. I can only
show you a flash video I produced. Its quality is questionable, as the
RRD graph output is a little blurry (because the recording software used
vnc to access the screen + video compression), but you'll get the idea.</font>
<br>
<br><font size=2 face="sans-serif">What's it doing, you ask. Well: It allows
to zoom in and out of any rrd graph using the mouse wheel and it allows
google-maps style panning of the graph using the mouse. See for yourself:

<br><font size=2 face="sans-serif">The link uses the wrong mime-type for
the file, but I'm too lazy to fix this, so you might have to d/l the file
and view it locally.</font>
<br>
<br><font size=2 face="sans-serif">It is implemented using my java-rrd
implementation for the server side (used via a java servlet) and about
200 lines of java script using jQuery and some services exposed using DWR
for AJAX between java script and the java server side.</font>
<br>
<br><font size=2 face="sans-serif">Tobi: What I was missing most when implementing
this was some indication of the absolute date/time a graph refers to. Note
the use of the right axis label for this. </font>
<br>
<br><font size=2 face="sans-serif">In theory, I could provide a standalone
servlet (+add'l stuff for DWR) for this, but it would require some rewrite
of the machinery to make it more self contained and I wonder if there is
a "market" for this.</font>
<br>
<br><font size=2 face="sans-serif">The movie shows the interaction between
my laptop as the server and an Atom-based desktop machine on a LAN. Its
responsiveness is not perfect (mostly depending on the server side CPU
performance), but it was never easier to view RRD data for me.</font>
<br>
<br><font size=2 face="sans-serif">Has this been done before?</font>
