During my visit at TRIUMF we rewrote the history plotting functionality of midas. Instead of
static GIF images, we have now interactive JavaScript panels where we can scroll, zoom,
inspect values and much more (example is attached). We are now in a state where this is still

I like the new history system very much, but I stumbled over a couple of issues.
I used the version "Thu Aug 29 08:24:29 2019 +0200 -
midas-2019-06-b-244-gdd6585bb on branch develop":

That's clearly a bug, I will fix it.

Our typical use case is that a lot of people are connected to the experiment
having some history tabs open most of the time. Hence, I setup a test system and
connect to it from all kind of systems/browsers. What I see currently quite

This is a most amazing achievement. We wanted to do this "for years" and I think we have

That has been implemented in meantime. Just click on the download arrow and you can save the current window in CSV or PNG format.

A new ODB flag has been introduced. When the logger is configured for automatic
stop and restart (/Logger/Auto restart = y), the restart delay was hard-wired
to 20 sec., which might be too long or short for some experiments. Therefore a

For those unfamiliar, odbxx is the interface that looks like a C++ map, but automatically syncs with the ODB - https://midas.triumf.ca/MidasWiki/index.php/Odbxx.

experiment name and directory usually used in the exptab file. This fixes
