jfreechart

I need to hide every second/third/forth item from the legend. IS there a way to achieve this in jFreeChart? thanks! Jason I have tried the above suggestion but it didn't seem to work for me. If you just want to remove series from the legend you can do it with the setSeriesVisibleInLegend() method. My scenario was that some of my series do not have a legend key. If they don't have a legend key then the series shouldn't be visible in the legend. I implemented this with the following code: for(int i = 0; i < seriesList.size(); i++){ if(seriesList.get(i).getKey() == null || seriesList.get(i)

My goal is to increase the size of "Revenue ($) " and "Years" . But I do not know how. I am able to increase the "Apples, Durians,Oranges" and "2012, 2013". Below are my codes. JFreeChart chart = ChartFactory.createBarChart3D("", // chart title "Years", // domain axis label "Revenue ($)", // range axis label dataset, // data PlotOrientation.VERTICAL, // orientation false, // include legend false, // tooltips false); CategoryPlot plot = chart.getCategoryPlot(); CategoryAxis axis = plot.getDomainAxis(); CategoryPlot p = chart.getCategoryPlot(); ValueAxis axis2 = p.getRangeAxis(); Font font = new

I was able to implement real-time mouse tracing as follow : The source code is as follow : http://jstock.cvs.sourceforge.net/viewvc/jstock/jstock/src/org/yccheok/jstock/charting/CrossHairUI.java?revision=1.5&view=markup http://jstock.cvs.sourceforge.net/viewvc/jstock/jstock/src/org/yccheok/jstock/gui/ChartJDialog.java?revision=1.9&view=markup However, I unable to obtained the correct y screen coordinate, when an subplot being added. (broken image) I suspect I didn't get the correct screen data area. When there is only one plot in the screen, I get a screen data area with height 300++ When a

I have a JFreeChart line plot that is updated dynamically with one data point for every iteration of my algorithm. Because the number of data points can quickly become very large, I have used the setFixedAutoRange(double) method on the domain axis. This restricts the graph to displaying the n most recent iterations (200 in my case). This works well, except during the first 200 iterations. The problem is that, until there have been 200 iterations, the axis includes negative values (for example, after 50 iterations, the range is from -150 to 50). Negative iterations make no sense. I would like

i am creating line chart using JFreeChart . Line chart draw properly but i want to start at point 0. how can i do that? public void lineChart() { CategoryDataset ds=createDataset2(); chart2=ChartFactory.createLineChart("Bar Chart", "OPD Number", "Weight", ds,PlotOrientation.VERTICAL,true,true,false); ChartPanel cp = new ChartPanel(chart2); jp.add(cp); //jp is JPanel } public CategoryDataset createDataset2() { final DefaultCategoryDataset dataset= new DefaultCategoryDataset(); final String series1 = "Type1"; OPDDetailBean ob=new OPDDetailBean(); ArrayList<OPDDetailBean> aob=new ArrayList

I am trying to create chart like below: While I've almost achieved everything by simply creating a line chart and customizing shape/paint for Renderer, I can't seem to find a way to fill the areas under the series line. Any clues, how can I do this? You could create your chart with a StackedXYAreaRenderer . Specify AREA_AND_SHAPES in the constructor and enable outlines. See the ChartFactory code for createStackedXYAreaChart() as an example. StackedXYAreaRenderer r = new StackedXYAreaRenderer(XYAreaRenderer.AREA_AND_SHAPES); r.setOutline(true); Given a renderer, you can set the outline paint

Recently I get a requirement to create a bar chart that show data for each project. Here's an example : As you can see, the Category is the name of the project, and Series are different types of data in that project. However, since system dose not guarantee the uniqueness of project name, using it as categories can cause problem, and I will not able to use project name to generate URL for different projects. On the other hand, If I use unique id as category, I won't able to display the project name. This put me into a difficult situation. So my problem is : Is there a way to generate customize

I'm going to plot a line chart that will change from solid line to dashed line to to indicate real data and forecasting data. I'm not sure if i need to extend some of the classes like XYLineAndShapeRenderer or something else, or maybe there is some convenient way to achieve this? Here is a demostration graph i plotted using Excel. I am talking about the gray lines in the graph. That is what i want. I don't know if there is a renderer that allow me to indicate which range dashed or solid There are two ways I can think of for doing this. Neither of them are elegant, but that may be the reality
