[Is there any way to rorate/flip an AnnotationText object?]

 The API (http://support.softwarefx.com/jChartFX/api#web_htmls/annotationtext_orientation.htm) says that there is an method setOrientation() but if i try something like this

        var annText = new cfx.annotation.AnnotationText();
        ...
        annText.setOrientation(1);

 the annotation is not shown anymore. I guess a script error.
