Cluster Visualization View cannot handle one dimensional data points

Reported by: mkommend Owned by: abeham
Priority: medium Milestone: HeuristicLab 3.3.12
Component: Problems.DataAnalysis.Views Version: 3.3.10
Keywords: Cc:

Description

The ClusterVisualizationView assumes that the points for visualization have two dimensions (line 84). However, if one dimensional data is clustered the data points are as well one dimensional and should played as a horizontal line in the used ScatterPlot. Currently an index out of range exception is thrown and nothing is displayed.

Reviewed r12614 and I have no idea what the calculate min / max bounds method do (especially the cascaded ifs). Furthermore, I got an exception while testing the cluster visualization (create new k-means, deselect one input variable, display visualization).
