I have xyline chart created using jfreechart inside netbeans swing.
I have two files one is for getting values for x and y coordinates continuously and other is for display of them now I am creating the chart from constructor of the display file and it displays the chart using hard coded values but when I pass my incoming the chart is not updating accordingly.
Please find below code for display file :
public Display_Unit_Mod() {
JPanel jPanel1 = createChartPanel();
}
public JPanel createChartPanel() {
String chartTitle = "";
String xAxisLabel = "x_value";
String yAxisLabel = "y_value";
XYDataset dataset = createDataset();
JFreeChart chart = ChartFactory.createXYLineChart(chartTitle,
xAxisLabel, yAxisLabel, dataset);
customizeChart(chart);
return new ChartPanel(chart);
}
public XYDataset createDataset() {
XYSeriesCollection dataset = new XYSeriesCollection();
XYSeries series1 = new XYSeries("");
System.out.println(String.valueOf(test.x_value));
System.out.println(String.valueOf(test.y_value));
series1.add(test.x_value,test.y_value); ->test is the object of other file and using it I am taking values from there
//series1.add(7.0,8.0);
//series1.add(3.0,4.0); -> displays values and prints chart
//series1.add(1.0,2.0);
dataset.addSeries(series1);
return dataset;
}
private void customizeChart(JFreeChart chart) {
XYPlot plot = chart.getXYPlot();
XYLineAndShapeRenderer renderer = new XYLineAndShapeRenderer();
// sets paint color for each series
renderer.setSeriesPaint(0, Color.RED);
// sets thickness for series (using strokes)
renderer.setSeriesStroke(0, new BasicStroke(4.0f));
renderer.setSeriesStroke(1, new BasicStroke(3.0f));
renderer.setSeriesStroke(2, new BasicStroke(2.0f));
// sets paint color for plot outlines
plot.setOutlinePaint(Color.BLUE);
plot.setOutlineStroke(new BasicStroke(2.0f));
// sets renderer for lines
plot.setRenderer(renderer);
// sets plot background
plot.setBackgroundPaint(Color.DARK_GRAY);
// sets paint color for the grid lines
plot.setRangeGridlinesVisible(true);
plot.setRangeGridlinePaint(Color.BLACK);
plot.setDomainGridlinesVisible(true);
plot.setDomainGridlinePaint(Color.BLACK);
}
I can see the values coming by system.out.println but not getting reflected on UI.
Please help me updating the same.
