Controlling numerical precision on lineChart axis

Question

Hi folks -
A simple thing I cannot seem to get to happen. I have an application that plots two numerical axes in a lineChart. I need to control the displayed precision of the values on the axes; ie if the value is floating point, for instance, I only want to display two decimal places as in '%2.2f' if this were C or some such. I can't seem to figure out how to do this in JavaFX (I am using 2.2). I saw the 'setTickLabelFormatter' but I do not understand how to use it. It wants an instance of a 'stringConverter' and I don't understand how to use that. can anyone give me a detailed example of how to use setTicklabelFormatter to set, say, 2.2f precision?
thank you.

Something like this should work:
        yAxis.setTickLabelFormatter(new StringConverter<Number>() {
               @Override
               public Number fromString(String string) {
                    return Double.parseDouble(string);
               @Override
               public String toString(Number value) {
                    return String.format("%2.2f", value.doubleValue());
        });
