Examples of weka.gui.AttributeVisualizationPanel$HistCalc

weka.gui.AttributeVisualizationPanel
Internal class that calculates the histogram to display, in a separate thread. In particular it initializes some of the crucial internal fields required by paintComponent() to display the histogram for the current attribute. These include: m_histBarCounts or m_histBarClassCounts, m_maxValue and m_colorList.

      JPanel temp = new JPanel();
      temp.setLayout(new BorderLayout());
      temp.setBorder(BorderFactory.createTitledBorder(m_visualizeDataSet.
                  attribute(i).name()));


      AttributeVisualizationPanel ap = new AttributeVisualizationPanel();
      m_plots.add(ap);
      ap.setInstances(m_visualizeDataSet);
      if (m_coloringIndex < 0 && m_visualizeDataSet.classIndex() >= 0) {
        ap.setColoringIndex(m_visualizeDataSet.classIndex());
      } else {
        ap.setColoringIndex(m_coloringIndex);
      }
      temp.add(ap, BorderLayout.CENTER);
      ap.setAttribute(i);
      hp.add(temp);
    }
    
    Dimension d = new Dimension(830, gridHeight * 100);
    hp.setMinimumSize(d);
