    <p>I'd like to ask if it is possible to have a time series chart with dual x-axis (or y-axis but because it is a time series dataset I focus on dual x-axis). I have two data files in which the measurements were made during a minute or a whole day. As a result I can't have one x-axis. So, one solution is to transmorm one data file to the format of the other or to have two different x-axis. The second solution is it possible to be done?</p> <p>I found <a href="http://www.java2s.com/Code/Java/Chart/JFreeChartDualAxisDemo2.htm" rel="nofollow noreferrer">JFreeChartDualAxisDemo</a></p> <p>but it isn't what I want.</p> <p>Thanks in advance for any help!!!</p> <p>EDIT:</p> <p>I have the following code and I'm trying to create a Time Series Chart with two datasets which belong to a specific x-axes (As you can see I created two x-axes). I tried to execute this code but the chart that creates isn't right and in fact it has only the x-axes and y-axis. Can someone tell me where is the fault? </p> <pre><code>int year1 = 2004; int year2 = 2005; int year3 = 2006; int year4 = 2007; int month1 = 1; int month2 = 5; int month3 = 8; int month4 = 12; int day1 = 3; int day2 = 10; int day3 = 15; int day4 = 30; TimeSeries ts= new TimeSeries("Metrisi", Day.class); ts.add(new Day(day1, month1, year1), 100); ts.add(new Day(day2, month2, year2), 150); ts.add(new Day(day3, month3, year3), 250); ts.add(new Day(day4, month4, year4), 275); TimeSeriesCollection dataset = new TimeSeriesCollection(); dataset.addSeries(ts); int year1_2 = 2004; int year2_2 = 2005; int year3_2 = 2006; int year4_2 = 2007; int month1_2 = 2; int month2_2 = 7; int month3_2 = 9; int month4_2 = 11; int day1_2 = 23; int day2_2 = 14; int day3_2 = 19; int day4_2 = 22; TimeSeries ts2= new TimeSeries("Metrisi", Day.class); ts.add(new Day(day1_2, month1_2, year1_2), 100); ts.add(new Day(day2_2, month2_2, year2_2), 150); ts.add(new Day(day3_2, month3_2, year3_2), 250); ts.add(new Day(day4_2, month4_2, year4_2), 275); TimeSeriesCollection dataset2 = new TimeSeriesCollection(); dataset.addSeries(ts2); JFreeChart chart = ChartFactory.createTimeSeriesChart( "Measurement", "Date", "Measurement", dataset, true, true, false); final XYPlot plot = chart.getXYPlot(); plot.setBackgroundPaint(Color.lightGray); plot.setDomainGridlinePaint(Color.white); plot.setRangeGridlinePaint(Color.white); plot.setDomainCrosshairVisible(true); plot.setRangeCrosshairVisible(false); final DateAxis axis2 = new DateAxis("Secondary"); //xAxis2.setAutoRangeIncludesZero(false); //plot.setDomainAxis(1, axis ); plot.setRangeAxis(1, axis2); plot.setDataset(1, dataset2); plot.mapDatasetToRangeAxis(1, 1); final XYItemRenderer renderer = plot.getRenderer(); renderer.setToolTipGenerator(StandardXYToolTipGenerator.getTimeSeriesInstance()); if (renderer instanceof StandardXYItemRenderer) { final StandardXYItemRenderer rr = (StandardXYItemRenderer) renderer; //rr.setPlotShapes(true); rr.setShapesFilled(true); //renderer.setSeriesStroke(0, new BasicStroke(2.0f)); //renderer.setSeriesStroke(1, new BasicStroke(2.0f)); } final StandardXYItemRenderer renderer2 = new StandardXYItemRenderer(); renderer2.setSeriesPaint(0, Color.black); //renderer2.setPlotShapes(true); renderer.setToolTipGenerator(StandardXYToolTipGenerator.getTimeSeriesInstance()); plot.setRenderer(1, renderer2); final DateAxis axis = (DateAxis) plot.getDomainAxis(); </code></pre> <p>This is what I'am trying to do. As you can see I have two x-axes but only one dataset and that it's the problem. I have done the example that is shown in the image with the following code:</p> <pre><code> final XYPlot plot = chart.getXYPlot(); plot.setBackgroundPaint(Color.lightGray); plot.setDomainGridlinePaint(Color.white); plot.setRangeGridlinePaint(Color.white); plot.setDomainCrosshairVisible(true); plot.setRangeCrosshairVisible(false); final XYItemRenderer renderer = plot.getRenderer(); if (renderer instanceof StandardXYItemRenderer) { final StandardXYItemRenderer rr = (StandardXYItemRenderer) renderer; //rr.setPlotShapes(true); rr.setShapesFilled(true); renderer.setSeriesStroke(0, new BasicStroke(2.0f)); renderer.setSeriesStroke(1, new BasicStroke(2.0f)); } final DateAxis axis = (DateAxis) plot.getDomainAxis(); final DateAxis xAxis2 = (DateAxis) plot.getDomainAxis(); plot.setDomainAxis(1, xAxis2 ); plot.mapDatasetToDomainAxis(1, 1); </code></pre> <p><img src="https://i.stack.imgur.com/tarov.jpg" alt="Example of the output that I want"></p>

    1. COPlease edit your question to include an [sscce](http://sscce.org/) that exhibits the problem you describe. This [duplicate question](http://stackoverflow.com/q/13563997/230513) is _not_ complete.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
