new line in title - gives a substitution like \n?

[Rahan]

Hallo i need an idea

The Title of my chart should have a new line break.
And the second line should be in the centre (not left like a big title)
gives a substitution like \n ?

Thanks

There is a problem with drawing strings with a new line character in them. One workaraund at the moment is to add subtitles for each line you wish to display.

Subtitles have the Problem that they are not have a method "setFont()" and then the font is very smal. You know an other method?

They do. Try something like this:

Code: Select all

TextTitle t = new TextTitle("whatever");
t.setFont(new Font("Arial", Font.PLAIN, 14));
chart.addSubtitle(t);

Yes i try it, too.

Here my Code for update the header with linebreak substituon -n

Code: Select all

protected void generateTitle (String titles, JFreeChart chart) {

		int numberOfSubtitle = (int)chart.getSubtitleCount();
		String[] result = titles.split("-n");
		chart.setTitle( result[0]); 
		System.out.println(result.length);
		for (int a=0+numberOfSubtitle; a<result.length; ++a) {
			TextTitle subtitle = new TextTitle(result[a]); 
			chart.addSubtitle(subtitle);
			chart.getSubtitle(a).setPosition(RectangleEdge.TOP);
			TextTitle subi = (TextTitle) chart.getSubtitle(a);
			subi.setFont(chart.getTitle().getFont());
		}

The title/subtitle mechanism is supposed to make it easy to add new types of titles, so if someone wants to contribute a custom title class that can handle multiple lines, that would be welcome.
