Examples with Partition org.gephi.appearance.api.Partition used on opensource projects

Example 1 with Partition

use of org.gephi.appearance.api.Partition in project gephi by gephi.

the class PartitionColorTransformerPanel method setup.

public void setup(PartitionFunction function) {
    this.function = function;
    NumberFormat formatter = NumberFormat.getPercentInstance();
    formatter.setMaximumFractionDigits(2);
    Partition partition = function.getPartition();
    values = partition.getSortedValues();
    List<Object> nullColors = new ArrayList<>();
    Color defaultColor = Color.LIGHT_GRAY;
    for (Object val : values) {
        Color c = partition.getColor(val);
        if (c == null) {
            nullColors.add(val);
            partition.setColor(val, defaultColor);
        }
    }
    int valuesWithColors = values.size() - nullColors.size();
    if (!nullColors.isEmpty() && valuesWithColors < 8) {
        Color[] cls = PaletteGenerator.generatePalette(Math.min(8, values.size()), 5, new Random(42l));
        int i = 0;
        for (Object val : nullColors) {
            int index = valuesWithColors + i++;
            if (index < cls.length) {
                partition.setColor(val, cls[index]);
            }
        }
    }
    //Model
    String[] columnNames = new String[] { "Color", "Partition", "Percentage" };
    DefaultTableModel model = new DefaultTableModel(columnNames, values.size()) {

        @Override
        public boolean isCellEditable(int row, int column) {
            return column == 0;
        }
    };
    table.setModel(model);
    String countMsg = NbBundle.getMessage(PartitionColorTransformerPanel.class, "PartitionColorTransformerPanel.tooltip.elementsCount");
    TableColumn partCol = table.getColumnModel().getColumn(1);
    partCol.setCellRenderer(new TextRenderer(null));
    TableColumn percCol = table.getColumnModel().getColumn(2);
    percCol.setCellRenderer(new TextRenderer(countMsg));
    percCol.setPreferredWidth(60);
    percCol.setMaxWidth(60);
    TableColumn colorCol = table.getColumnModel().getColumn(0);
    colorCol.setCellEditor(new ColorChooserEditor());
    colorCol.setCellRenderer(new ColorChooserRenderer());
    colorCol.setPreferredWidth(16);
    colorCol.setMaxWidth(16);
    int j = 0;
    for (Object value : values) {
        String displayName = value == null ? "null" : value.getClass().isArray() ? AttributeUtils.printArray(value) : value.toString();
        int count = function.getPartition().count(value);
        float percentage = function.getPartition().percentage(value) / 100f;
        model.setValueAt(value, j, 0);
        model.setValueAt(displayName, j, 1);
        String percCount = count + "_(" + formatter.format(percentage) + ")";
        model.setValueAt(percCount, j, 2);
        j++;
    }
}

Example 2 with Partition

use of org.gephi.appearance.api.Partition in project gephi by gephi.

the class PartitionPanel method setup.

public void setup(final PartitionFilter filter) {
    this.filter = filter;
    final Partition partition = filter.getPartition();
    if (partition != null) {
        refresh(partition, filter.getParts());
    }
