Need help in pointing 2 Y values for a single date(X-axis) in JFreeChart

[Kushi Gadiparthi]

Hello Experts,

Can somebody help me for drawing a Line Graph in which Y-axis has time in Hours and the X-axis has Date.
I was able to draw the graph for the values which has one to one relationship.

But now I wanted to draw line for 2 Y values for the same date on the X value

I am placing my code here, Can anybody give some ideas for how to succeed it. This code is not pointing to the 2 Y values, It is taking only one value into account.

BasicTimeSeries InputTimeSeries = new BasicTimeSeries("INPUT", Day.class);
					
//Getting Date from EJB into Input Graph Fields
graphdataInput.first();
for (int j = 0; j < graphdataInput.getRowCount(); j++) {
Date Inputday = new Date(graphdataInput.getString("IPCreatedDate"),"yyyy-MM-dd");
double Inputtimeinsec = graphdataInput.getInt("IPCreatedTimeInSeconds");
											
//Calculations for displaying the time in Hours
double Inputtimeinhours = (Inputtimeinsec/3600);
BigDecimal bdTest = new BigDecimal(Inputtimeinhours); 
bdTest = bdTest.setScale(2, BigDecimal.ROUND_HALF_UP); 
double InputTimeval  = bdTest.doubleValue(); 

InputTimeSeries.addOrUpdate(new Day(Inputday.get(Calendar.DAY_OF_YEAR),
Inputday.get(Calendar.MONTH) + 1, Inputday.get(Calendar.YEAR)), InputTimeval);
graphdataInput.next();
}

TimeSeriesCollection InputTimeCollection = new TimeSeriesCollection();
InputTimeCollection.addSeries(InputTimeSeries);

final JFreeChart Inputchart = ChartFactory.createTimeSeriesChart(inputstepnamevalue, "Date", "INPUT",
			InputTimeCollection, true);
//Customizing the Chart Area
final XYPlot Inputplot = Inputchart.getXYPlot();
Inputplot.setSeriesPaint(0, new Color(176,48,96));
					
final NumberAxis Inputaxis = new VerticalNumberAxis("INPUT");
Inputaxis.setAutoRangeIncludesZero(true);
 Inputaxis.setAutoRangeMinimumSize(0);
final StandardXYItemRenderer renderer1 = new StandardXYItemRenderer();
renderer1.setToolTipGenerator(new TimeSeriesToolTipGenerator("dd-MM-yyyy", "##.## Hours"));
renderer1.setPlotShapes(true);
renderer1.setDefaultShapeFilled(true);
renderer1.setDefaultShapeScale(5.0);
Inputplot.setRenderer(renderer1);
//Setting Background Color to Graph
Inputchart.setBackgroundPaint(UIManager.getColor("Color.default"));
InputchartPanel = new ChartPanel(Inputchart);
// Adding ChartPanel to the ChartScrollPane
getChartScrollPaneInput().getViewport().add(this.InputchartPanel);
InputchartPanel.setVisible(true);

Thanks in Advance
