legend in thermometer plot (to explain subrange colors)?

[gkatzusr]

hi all;
I would like to add an explanation (legend per my understanding displayed somewhere on the chart) to a thermometer chart in order to explain subrange colors. for example:
[red]=hot
[yellow]=cool
[blue]=cold
I was able to define the sub ranges and their color, but I cant seem to find the way to add the descriptive text to these colors.
your help is appreciated.,
thanks.

To add a legend with manually specified entries, you can do something like this:

Code: Select all

            LegendTitle legend = new LegendTitle(new LegendItemSource() {
                @Override
                public LegendItemCollection getLegendItems() {
                    LegendItemCollection items = new LegendItemCollection();
                    items.add(new LegendItem("Item A", Color.RED));
                    items.add(new LegendItem("Item B", Color.GREEN));
                    items.add(new LegendItem("Item C", Color.BLUE));
                    return items;
                }
            });
            legend.setPosition(RectangleEdge.RIGHT);
            chart.addLegend(legend);
