jfreechart

This is the situation: My 'metrics.jsp' page submits a couple variables that are needed to create the chart. The 'ProjectActionBean.java' calls down to a few other java classes that create the JFreeChart. I can display the chart in a pop-up but I want it to be displayed in the original browser window. JFreeChart placeChart = ChartFactory.createBarChart( "ChartName", "", //x-axis label "", //y-axis label dataset, PlotOrientation.VERTICAL, false, //legend true, //tooltype false); //generate urls ChartFrame frame = new ChartFrame(name, placeChart); frame.pack(); frame.setVisible(true); I've

Let's say I've generated a chart with the following code: private ChartPanel createChart(){ XYSeries series1 = new XYSeries("First"); XYSeries series2 = new XYSeries("Second"); XYSeries series3 = new XYSeries("Third"); series1.add(0.0, 5.5); series1.add(5, 10); series1.add(10, 5.5); series2.add(0.0, 2); series2.add(5, 2); series2.add(10, 7); series3.add(0.0, 10); series3.add(5, 5); series3.add(10, 6); XYSeriesCollection dataset = new XYSeriesCollection(); dataset.addSeries(series1); dataset.addSeries(series2); dataset.addSeries(series3); JFreeChart chart = ChartFactory.createXYLineChart("line

I'm using SpiderWebPlot from JFreeChart in order to generate a chart. But what I want to have, is tooltips with values. I've found that I should set StandardCategoryTooltipGenerator to the plot, but that doesn't seem to be the point. Here is my sample code: private JFreeChart prepareChart() { Random rnd = new java.util.Random(); DefaultCategoryDataset dataSet = new DefaultCategoryDataset(); String rowKey = "Osobnik"; dataSet.addValue(rnd.nextInt(20), rowKey, "BLUFF"); dataSet.addValue(rnd.nextInt(20), rowKey, "CALL"); dataSet.addValue(rnd.nextInt(20), rowKey, "CHECK"); dataSet.addValue(rnd

I'm trying to show the histogram of an image and show only some colors. I've already done that with JFreeChart and createXYLineChart and getting all the data by iterating over all pixels. To speed it up I'm trying to do it with "createHistogram". I've followed this code . To update the chart with the new values I've used this two methods: XYPlot plot = (XYPlot) chart.getPlot(); plot.setDataset(setHistogram(red, green, blue)); Being setHistogram a method which returns a HistogramDataset depending on which checkbox are activated (boolean red, green and blue). That works properly as intended. The

I want to make bar chart using jfreechart such that the bars which belong to the same category should be displayed adjacent without any gaps. The categories should be displayed with gaps. Also each category may have different number of bars. How it can be achived using Jfreechart library? Following image is the sample of what I require. Here all the bars of same category should be of same color and with no gap(or a very little gap). Thanks in advance, Abhinav I am aware of the age of this post. Anyway I am posting my solution, maybe someone else who will find himself here looking for the

I would like to disable zooming by mouse dragging(which paints that rectangle), but not disable zooming by MouseWheel. I found in another topic how to disable zoom reset while dragging mouse to left (restoreAutoBounds) and I'm interested in how to solve this problem. Is there a little shortcut to do that? Ok, I've done it, by overriding MouseWheelListener. After chartPannel.setMouseZoomable(false).: chartPanel.addMouseWheelListener(new MouseWheelListener() { public void mouseWheelMoved(MouseWheelEvent arg0) { if (arg0.getWheelRotation() > 0) { chartPanel.zoomOutDomain(0.5, 0.5); } else if
