I can send you a pdplot input if you want to see what I'm up against.
I got it to work, and the results are somewhat more usable that
gnuplot in some ways, but less in other ways.  Some first impressions:

1. The Time axis should have an option for time(2) format, converting
   to day/hours/sec etc.  Currently, it shows the ten digit values in
   scientific format, which overlap.

2. It doesn't label the individual graphs, so you can't tell which
   graph is which.

3. The zooming is different than everyone else - should be click-drag
   rectangle (with outline), release to zoom.  The second point should
   be allowed to be just outside the plot so you can reliably grab the
   zero axis.

4. Dude, scrollbars :-)

5. The git clone command fails.

6. The "homepage" link opens the homepage within a frame, need to
   re-target the top window.

7. If it had the ability to enable/disable the various graphs through
   the GUI, it'd be nearly prefect for me, caveat the above.

Thanks!
