How to keep an icon in one side of a chart in JFreeChart Java

I have the following chart:
The chart is dynamic and has the capability of make zoom in and zoom out.
I want to put an icon that is created as:
BufferedImage triangleIcon = null;
try {
triangleIcon = ImageIO.read(getClass().getClassLoader().getResource("Resources/Imagenes/triangulo.png"));
} catch (IOException e) {
}
And can be placed in any point as:
xyannotation = new XYImageAnnotation(XValue, YValue, triangleIcon);
this.xyplot.addAnnotation(xyannotation);
I want to put this icon at any Y value but always next to the left side of the chart, without taking into account the zoom. Something like:
Is it possible?

I looks like you want to annotate "one side of the…chart, ignoring the value of the X axis". Ordinarily, such annotations specify both coordinates in data space. One approach is a custom annotation that extends the abstract parent, AbstractXYAnnotation. Override draw() to transform the vertical data coordinate to the corresponding screen coordinate, while pinning the horizontal screen coordinate to the dataArea of the plot. Pan and zoom to see the effect.
AffineTransform at = new AffineTransform();
…
#Override
public void draw(…) {
RectangleEdge rangeEdge = plot.getRangeAxisEdge();
double y = rangeAxis.valueToJava2D(yValue, dataArea, rangeEdge);
at.setToIdentity();
at.translate(dataArea.getX() + 1, y);
…
}

JFreeChart is plotting data but not drawing linear regression

I have used JFreeChart to represent my array of x and y. These arrays get plotted just fine, however theregression line is broken and never gets drawn. All the functions work such as plotting values except drawinputpoint and drawregressionline function. Somehow these two never work. I don't mind drawwinginputpoint a lot, but I like to be able to drawregressionline. My array has correct data, so not sure what is the issue. I am importing my arrays data into dataset in createDateSetFromFile function. My Home_JFrame has targetx and targety array. These have arraylist and has Double data type.

It looks like you want a trend line though a scatter plot, but you may be creating unnecessary renderers in addition to the one instantiated by your chosen ChartFactory. To study the problem in isolation, modify this complete example to create a scatter plot and change the existing renderer to condition the trend line's display as desired.
JFreeChart chart = ChartFactory.createScatterPlot(…);
XYPlot plot = chart.getXYPlot();
XYLineAndShapeRenderer r = (XYLineAndShapeRenderer) plot.getRenderer();
r.setSeriesLinesVisible(1, Boolean.TRUE);

How to draw moving and Running sine wave chart using JFree chart in java?

I m using JFreeChart to draw Running or Moving Sine Wave in java with netbeans. I write code for it , but it does not like moving or running sine wave graph. So if you have any idea regarding that then suggest me.
My code is below
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JPanel;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.chart.plot.XYPlot;
import org.jfree.data.xy.XYDataset;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;
import org.jfree.ui.ApplicationFrame;
public class DrawChart extends ApplicationFrame implements ActionListener {
public XYSeries series;
public DrawChart(final String title) {
super(title);
series = new XYSeries("Sine", true, true);
XYSeriesCollection dataset = new XYSeriesCollection(series);
final JFreeChart chart = createChart(dataset);
final ChartPanel chartPanel = new ChartPanel(chart);
final JButton button = new JButton("Add New Data Item");
button.setActionCommand("ADD_DATA");
button.addActionListener(this);
final JPanel content = new JPanel(new BorderLayout());
content.add(chartPanel);
content.add(button, BorderLayout.SOUTH);
chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));
setContentPane(content);
}
private JFreeChart createChart(final XYDataset dataset) {
JFreeChart jfreechart = ChartFactory.createXYLineChart("Sin Curve", "Angle (Deg)", "Value", dataset, PlotOrientation.VERTICAL, true, true, true);
jfreechart.setBackgroundPaint(Color.white);
XYPlot xyplot = (XYPlot) jfreechart.getPlot();
xyplot.setBackgroundPaint(Color.lightGray);
xyplot.setDomainGridlinePaint(Color.white);
xyplot.setRangeGridlinePaint(Color.white);
return jfreechart;
}
public void actionPerformed(final ActionEvent e) {
if (e.getActionCommand().equals("ADD_DATA")) {
for (int i = 0; i < 100; i++) {
final double x = (i)/10.0 ;
final double y = Math.sin(x);
this.series.addOrUpdate(x, y);
}
}
}
public static void main(final String[] args) {
final DrawChart demo = new DrawChart("Dynamic Data view");
demo.pack();
RefineryUtilities.centerFrameOnScreen(demo);
demo.setVisible(true);
}
}

Starting from this example, substituting Math.sin() for nextGaussian() produced the illustration below. A javax.swing.Timer paces the animation at 1 Hz.
private ChartPanel createPane() {
final XYSeries series = new XYSeries("Data");
for (int i = 0; i < random.nextInt(N) + N / 2; i++) {
series.add(i, Math.sin(i));
}
XYSeriesCollection dataset = new XYSeriesCollection(series);
new Timer(1000, new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
series.add(series.getItemCount(), Math.sin(series.getItemCount()));
}
}).start();
…
}

Update graph with JFreeChart and slider

I have a time history for arrays describing the pressure along a pipe. So I have an array of pressure values along the length of the pipe for each delta t. I want to plot the pressures along the length of the pipe with JFreeChart and chose which delta t to plot with a slider, so that whenever the user moves the slider the graphic is updates with values from a different delta t. I'm also resetting the tile to be the pressure at the last portion of the pipe. What happens is that the title is updates, meaning the data is being properly updates, but the curve remains the same. I have read every possible topic on forums and tried everything I could think of but it's not working! Here's the code of my class that extends JPanel, in which the method jSlider1StateChanged hears the change in the slider position, createChart creaters a new chart when the program is started, and dataSetGen(int ndt) generates the graph's new dataset based on the slider position:
public class MyMainPanel extends JPanel {
private JFreeChart jc;
private OutputPipe op;
private DefaultXYDataset ds;
private javax.swing.JFrame jFrame1;
private javax.swing.JSlider jSlider1;
private pipevisualizer.MyChartPanel pnlChartPanel;
private void jSlider1StateChanged(javax.swing.event.ChangeEvent evt) {
int ndt = ((JSlider) evt.
getSource()).
getValue();
System.out.println("Slider1: " + ((JSlider) evt.
getSource()).
getValue());
dataSetGen(ndt);
int a = 0;
jc.fireChartChanged();
}
private void dataSetGen(int ndt) {
ArrayList<OutputPipeDt> opDtArray = op.getOpLit();
OutputPipeDt opDt = opDtArray.get(ndt);
double[] H = opDt.getH();
double[] l = new double[H.length];
double[] p = new double[H.length];
double dX = op.getPipeLength() / H.length;
double slope = op.getPipeSlope();
double el = op.getPipeUSElev();
for (int i = 0; i < H.length; i++) {
l[i] = dX * i;
p[i] = el - dX * slope * i;
}
double[][] dataH = new double[2][H.length];
dataH[0] = l;
dataH[1] = H;
double[][] dataP = new double[2][H.length];
dataP[0] = l;
dataP[1] = p;
ds = new DefaultXYDataset();
ds.addSeries("pipe head", dataH);
ds.addSeries("pipe profile", dataP);
jc.setTitle("H[end] = " + Double.toString(dataH[1][l.length - 1]));
jc.fireChartChanged();
}
private JFreeChart createChart(OutputPipe op, int ndt) {
ArrayList<OutputPipeDt> opDtArray = op.getOpLit();
OutputPipeDt opDt = opDtArray.get(ndt);
double[] H = opDt.getH();
double[] l = new double[H.length];
double[] p = new double[H.length];
double dX = op.getPipeLength() / H.length;
double slope = op.getPipeSlope();
double el = op.getPipeUSElev();
for (int i = 0; i < H.length; i++) {
l[i] = dX * i;
p[i] = el - dX * slope * i;
}
double[][] dataH = new double[2][H.length];
dataH[0] = l;
dataH[1] = H;
double[][] dataP = new double[2][H.length];
dataP[0] = l;
dataP[1] = p;
DefaultXYDataset ds = new DefaultXYDataset();
ds.addSeries("pipe head", dataH);
ds.addSeries("pipe profile", dataP);
JFreeChart chart = ChartFactory.createXYLineChart(
"t = " + Double.toString(op.getOpLit().get(ndt).getT()),
// chart title
"X",
// x axis label
"Y",
// y axis label
ds,
// data
PlotOrientation.VERTICAL,
true,
// include legend
true,
// tooltips
false // urls
);
return chart;
}
}
I thought that any changes to the datasets would make the graph redraw itself.
Sorry if the code might be to big to be on the post, but I don't know exactly which parts should I paste to be more or less clear.

Absent a complete example, you may be able to use the approach shown here; it uses plot.setDataset() to replace the dataset on receiving each event.
Addendum: This example that shows temperature versus length over time may get you started.

Setting Range for X,Y Axis-JfreeChart

Any suggestions over how to set Range for X-Axis and Y-Axis.
My "X-Axis" Range is from "0.00 to 1.00" with difference of "0.05". I mean 0.00 0.05 0.10 0.15.....0.90 0.95 1.00
My "Y-Axis" Range is from "0.0 to 1.0" with difference of "0.1". I mean 0.0 0.1 0.2 0.3 0.4.........0.9 1.0
I tried doing this Way, but it's not reflecting on the Graph; I don't know how to apply it to ChartFactory.createScatterPlot().
final NumberAxis domainAxis = new NumberAxis("X-Axis");
domainAxis.setRange(0.00,1.00);
domainAxis.setTickUnit(new NumberTickUnit(0.1));
final NumberAxis rangeAxis = new NumberAxis("Y-Axis");
rangeAxis.setRange(0.0,1.0);
rangeAxis.setTickUnit(new NumberTickUnit(0.05));
public JPanel createDemoPanel() {
XYDataset dataset1 = samplexydataset2();
JFreeChart jfreechart = ChartFactory.createScatterPlot("Scatter Plot Demo",
"X", "Y",dataset1, PlotOrientation.VERTICAL, true, true, false);
}
Any help regarding this would be great.

I'm guessing your new NumberAxis instances aren't being used by the plot; it may be easier to use the existing ones from the factory.

Unless the code that you pasted is incomplete, it looks like your problem is that you didn't associate the NumberAxis objects that you created with your plot.
Instead of creating new NumberAxis objects manually, try getting the default ValueAxis objects that are associated with your plot, then modifying their properties:
XYPlot xyPlot = jfreechart.getXYPlot();
ValueAxis domainAxis = xyPlot.getDomainAxis();
ValueAxis rangeAxis = xyPlot.getRangeAxis();
domainAxis.setRange(0.0, 1.0);
domainAxis.setTickUnit(new NumberTickUnit(0.1));
rangeAxis.setRange(0.0, 1.0);
rangeAxis.setTickUnit(new NumberTickUnit(0.05));
