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

Indeed there was a bug in some JavaScript code, which I fixed here: https://bitbucket.org/tmidas/midas/commits/d2b1a783240e252820c622001e15c09c5d7798c0
Note that your code will bring you the "old style" history panels (with GIF images). If you want the new style (interactive canvas panels), you need the |

Dear Stefan,
thank you very much for the prompt reply. Your suggestions worked wonderfully. Now I can display all the plots that I want where I want.
The new JavaScript history plots are really a huge improvement over the old ones.

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 little advertised feature of the modifications needed support the msysmon program is
that MIDAS equipment names can support the injecting of the hostname of the system
running the frontend at runtime (register_equipment(void)).

Hello!
As you know, the generic MIDAS frontend has a class driver, device driver, bus driver
structure. Assuming a slow device frontend, its class driver should have a routine of type

Dear Konstantin,
thank you very much for the explanation. I already have an idea of how to solve my problem by bypassing the class driver altogether or by slightly modifying
the mfe.cxx frontend.

It is important to note that slow control readout and sending of midas events are two separate things. Readout is done as fast as possible, even multi-threaded
if selected. On fast devices this can be 100 Hz readout rate and even more. This data is stored in an internal buffer. When one of the values changes by
more than the update threshold, then the ODB gets updated. The midas events are composed from this internal buffer when a new event has to be sent. This |
