## Detailed Description

Panel widget using tulip data to compute statistical results.

This class is a widget which takes places in the main interface of tulip, in the tabwidget of properties. This panel has mainly 3 uses :

-Firstly : It changes the graph placement and order it under the form of an histogram or a scatter plot according to a defined number of metrics (up to 3). -Secondly : It computes and display some basic statistics results on the graph : average, variance, standard deviation, bounding box, linear regression and eigenvectors. -Thirdly : It clusterize the graph by a plane which is based upon statistic results calculated above.
