Custom data labels for Line Plot

[spidru]

I'm aware that recently, data labels have been added to XChart. However, I believe it is still not possible to label markers with custom strings. What I have in mind is something as shown below:

double[] xData = new double[10];
double[] yData = new double[10];
String[] labels = new String[10];
XYChart chart = new XYChartBuilder().build();
...
XYSeries series = chart.addSeries("demo", xData, yData, labels)

To set custom tooltips use series.setToolTips().

Thanks @hakantkn !

To make tooltips always visible use

chart.getStyler().setToolTipsEnabled(true);
chart.getStyler().setToolTipsAlwaysVisible(true);

To disable tooltips for single series, I use setToolTips() passing an array of null Strings.
