printing from a ListView Javafx

I hava a javafx application where the user enters some details in test fields and it is shown on a listview. I now have a button to print using the printjob but everytime I hit the print button the printer prints garbage data like jhsjs6sh3#uhbsbkahi instead of the real values from the ListView. below is my codes for the print functon
public void print (final Node node) {
Printer printer = Printer.getDefaultPrinter();
PageLayout pageLayout = printer.createPageLayout(Paper.A4, PageOrientation.PORTRAIT, Printer.MarginType.HARDWARE_MINIMUM);
final double scaleX = pageLayout.getPrintableWidth() / node.getBoundsInParent().getWidth();
final double scaleY = pageLayout.getPrintableHeight() / node.getBoundsInParent().getHeight();
node.getTransforms().add(new Scale(scaleX, scaleY));
PrinterJob job =PrinterJob.createPrinterJob();
if (job != null ){
boolean success = job.printPage(node);
System.out.println("printed");
if (success){
System.out.println(success);
job.endJob();
}
}
}
#FXML

 private void printOps(ActionEvent event){

}
I use a MacBook for my development and HP printer.

You will have to figure out the scaling. This prints using SnapShot and awt. Using code from here.

Why is the slider for this Java program is not working?

This is a fan program where use a slider to increase and decrease the speed of the fan. I do not need the increase and decrease button, I only have them as a guide to help the slider figure out what happens when you scroll left or right. I will delete those later. My slider is not showing and I can't test it out. Where did I go wrong here?

Sorting XYChart Series Data

Hello I have added data to a XYSeries and am trying to get that data sorted from shortest length to largest. I don't know how to manipulate this data, Can anyone help me out. This is my code:
xLabel = "Link Id";
yLabel = "Length (Km)";
bc = new BarChart<>(xAxis,yAxis);
bc.setTitle(gTitle);
//Set x/y Axis Label
//xAxis.setLabel(xLabel);
yAxis.setLabel(yLabel);
//double[] lengthArray = new double[linkIds.length];
XYChart.Series series1 = new XYChart.Series();
series1.setName(xLabel);
for (Integer m = 0; m < linkIdsOTS.length; m++) {
double length = netPlan.getLinkLengthInKm(otsLayerId, m);
//lengthArray[i] = length;
series1.getData().add(new XYChart.Data(m.toString(), length));
}
bc.getData().addAll(series1);

Assuming your Series and Data are properly typed, you should be able to do
series1.getData().sort(Comparator.comparingDouble(d -> d.getYValue().doubleValue()));

Thank u in advance for helping and taking efforts to see this.

I want to override few more spider graphs on the same chart.
It may help to examine how a spider web plot is used to display multivariate data. The simplified example below compares just two OBSERVATIONS, each having five VARIABLES named A .. E, with random values in the range 1 .. 3. By chance, the values for variable B coincide; the rest differ. You can adjust the value of OBSERVATIONS to see the effect, but the result becomes progressively more muddled as the number of observations grows. You may want to alter series visibility, as suggested here, or consider these alternatives.

You can enable the trace feature to follow the mouse, as shown here. You can add a ChartMouseListener to see the ChartEntity under the mouse, as shown here.
Addendum: Given a these instatiations,
JFreeChart chart = new JFreeChart(…);
chartPanel = new ChartPanel(chart);
This complete example enables trace:
chartPanel.setHorizontalAxisTrace(true);
chartPanel.setVerticalAxisTrace(true);
This complete example adds a ChartMouseListener:
chartPanel.addChartMouseListener(new ChartMouseListener() {
#Override
public void chartMouseClicked(ChartMouseEvent e) {
final ChartEntity entity = e.getEntity();
System.out.println(entity + " " + entity.getArea());
}
#Override
public void chartMouseMoved(ChartMouseEvent e) {
}
});

Hey guys i found the answer to this ..Thanks trashgod for helping me out..The following code helps to draw a barchart with a moving cross hair and the y coordinate is displayed on a JLabel.The CL.txt file contains nothing but date,open,close,high,low (all are double values).
