Version: HEAD (using KDE KDE 3.3.0) Installed from: Compiled From Sources OS: Linux PROBLEM: Any newly created histograms have all zero values in the corresponding vector, and so no histogram data is displayed in the plot. STEPS TO REPRODUCE: Create a new histogram using any variation of binning and data source EXPECTED RESULTS: Histogram is calculated and displayed RESULTS: The histogram is calculated as being zero for all bins, and no histogram is displayed.
There seems to be a similar problem with creation of matrices. Haven't tested similar objects: equations, events, etc.
