Abstract :
LHCb is one of the four major experiments under completion at the Large Hadron Collider (LHC). One crucial aspect of the experiment is the online data quality monitoring, part of which project is the LHCb Histogram Presenter, a flexible tool dedicated to the visualisation of online histograms. Data quality monitoring is important, because it allows the verification of the detector performance: anomalies, such as missing values or unexpected distributions of summary statistical data can be indicators of a malfunctioning detector.
