From source file:de.bfs.radon.omsimulation.gui.data.OMCharts.java

/**
 * Creates a chart displaying the distribution of certain selected statistical
 * values. Uses red for normal rooms and blue for cellar rooms.
 * //w  w w  . j  ava 2 s.  co  m
 * @param title
 *          The headline of the chart. Will be hidden if set to null.
 * @param statistics
 *          The selected statistics of a campaign containing all needed
 *          values.
 * @param roomType
 *          The room type to determine the colour of the chart.
 * @param preview
 *          Will hide annotations, labels and headlines if true.
