I have added some additional features to the example webdisplay that we have for
ROOTANA data (where we are displaying rootana data through ROOT THttpServer).  

The main improvement to the display is that I added the ability to plot the data
using the JSROOT package [1].  Previously I had used different packages (dygraphs
and plot-ly) for plotting.  The JSROOT plots are not obviously superior, though they
do present data in a more familiar way (at least for me).  The rootana webdisplay
currently  allows you to switch between the two different styles.

You can see a working example of the webdisplay here:

All details on setting up that example are here:

I'm interested in any feedback on which plotting style people prefer (or any other
aspects of the rootana webdisplay).
