The diagram `Squeal conditions´ shows correlations between noise events and any ambient conditions. The x- and y-axis can be defined freely to find interesting combinations. A zoom option allows to magnify any section of the diagram.

Based on the same principle like `Squeal conditions´, the diagram `Squeal probability´ estimates a probability density function for brake noise under certain conditions. The 3D-surface can be rotated freely to get the best view on the plot.
