Mysterious subtitle

I am writing a custom chart customization panel that people can use to change the appearance of charts created with JFreeChart. None of the charts should have any subtitles by default so I expected that the code inside the if statement would be skipped.

Code: Select all

if (chart.getSubtitleCount() > 0)
{
        this.txtSubTitle.setText(((TextTitle) chart.getSubtitle(0)).getText());
        this.txtSubtitleFont.setText(((TextTitle) chart.getSubtitle(0)).getFont().toString());
}

It isn't skipped, and instead I get a ClassCastException. Apparently, the call to getSubtitle is returning a LegendTitle instance. I have looked at the code for JFreeChart, and can't find where this mysterious subtitle is being created. Can someone shed some light on this please.

In the latest release, a new LegendTitle class is used to display the legend. It is now a regular chart title (or subtitle) so you can place it anywhere a chart title can go, and you can have more than one legend. The legend is created in the JFreeChart constructor.

Great! Thanks for shedding some light on that.
