General changes
OHP is the new Online Histogram Presenter that should be used instead of PMPpresenter.
The GUI remains unchanged but the underlying system has changed to allow
more stability and scalability.
OHP is the default Histogram Presenter from TDAQ release 01-06-00, but it is compatilble with
both tdaq-01-04-01 and tdaq-01-05-00 and it is provided to this releases as a patch. If you are
using PMPpresenter please switch to OHP since support to PMPpresenter is no more foreseen.
The configuration file syntax has changed in some points. Read the PMP2ohp file in the doc
directory on how to import a configuration file for PMPpresenter to the new format.
The OHP now fully supports the notification mechanism, this means that when a provider publishes
a histogram in OHS only a notification is propagated to OHP, the presenter will get the histogram
only if it has to be displayed in the active window. Since this is done automatically no user action
is required.
Command line parameters has been changed too. For more details, please refer to the "REDME" file (in the ohp installation directory).
New drawing options are supported. In share directory a commented example (example.conf) is provided
with instructions on how to write a configuration file for OHP.
OHP now supports receiving of reference histograms from OHS and from local ROOT files, more information
in the example.conf file.
To be implemented
- Support for configuration files in XML format;
