 09 Feb 2010, Stefan Ritt, Forum, custom page - flashing filled area 
|
One possibility is to use small GIF images for each valve, which have several frames (called 'animated GIF'). Depending on the state you can use a static
GIF or the flashing GIF. An alternate approach is to use a static background image, and display a valve with different color on top of the background in
regular intervals using JavaScript. I tried that with the attached page. Just create a custom page
/Custom/Valve = valve.html
and put all three attachments |

04 Dec 2009, Stefan Ritt, Info, Custom page showing ROOT analyzer output
|
Many midas experiments work with ROOT based analyzers today. One problem there is that the graphical output of the root analyzer can only be seen through
the X server and not through the web. At the MEG experiment, we solved this problem in an elegant way: The ROOT analyzer runs in the background, using
a "virtual" X server called Xvfb. It plots its output (several panels) normally using this X server, then saves this panels every ten seconds into GIF |

barely used, I decided to drop it. Anyhow it does not make sense for all slow
control events. If this feature is required in some experiment, I propose to move it
