Examples of simtools.ui.ColorMapper

simtools.ui.ColorMapper
This class maps data sources and index to colors. The mapping is user defined, and based for example on the value of the data source For example, green value < 10, red above. Useful for making plots with "alarm" colors The data source shall not be saved into the object. Rather, this class goal is to implement a mapping independent of the data source given.

        dst.setDataSourceCollection((DataSourceCollection)o); 
        chart.setTitle(dst.getName());
        for (int i=0; i<mappers.size(); ++i) {
          DataSource ds = (DataSource)mapperSources.get(i);
          if (ds!=null) ds.removeListener(this);
          ColorMapper cm = (ColorMapper)mappers.get(i);
          if (cm!=null) cm.removeListener(this);
        }
        for (int i=0; i<((DataSourceCollection)o).size(); ++i) {
          mappers.add(null); mapperSources.add(null); // no mapper by default
