jfreechart

I am using JFreeChart to plot a timeseries chart. The chart is working fine, but the gridline alignment is becoming a problem. My requirement is to show the horizontal gridlines through the peak values (i.e for the max and min value). Could you please let me know if there is any property for this, as I am getting grids randomly. Have you considered using a Marker to highlight the min and max values? As trashgod sugested you use the Dataset to get the minimum and maximum values and then add a Marker to the Plot Range range = dataset.getRangeBounds(true); plot.addRangeMarker(new ValueMarker

I have below mentioned 4 xml files in which i have state & key & BuildDate. I need to represent the "state" information of "key" in a graph based on BuildDate. The x-axis should have past 6 days (w.r.t current date. suppose today is 7th Sept then the entry should be from 1st to 6th Sept). If there is an entry for the corresponding date in BuildDate feild then the state should be displayed as red or green (Failed - red, Success - green). Otherwise black should be displayed. I am mainly struggling in adding the value & displaying according to date. How can i do this via jfreechart?

I want to display a jfreechart chart in a jsp page. I have written code as follows - ... <% ChartCreator chart = new ChartCreator(); chart.createCategoryChart(); %> <img src = "chart.jpg"/> where the createCategoryChart() method creates the required jpg. It is stored in the eclipse folder(i have not put any path in my filename). I am not able to view the chart in the jsp page, but the file is created. What am I doing wrong? I would suggest to use Servlet to create Chart. JSP is mainly used for presentation (View). Create a servlet which creates the chart and send back it as response. import

Currently, my TimeSeries graph shows the temperature of a location every 2 seconds. Now, if I want to show the rainfall index along with the temperature every 2 seconds, how can I achieve it? Here is my code: import testWeatherService.TestWeatherTimeLapseService; public class graph extends JFrame implements ActionListener { private static TimeSeries series; static final int COUNT = 200; /** The Constant WINDOW. */ public static final int WINDOW = 25; TestWeatherTimeLapseService getLocData = new TestWeatherTimeLapseService(); public graph(final String title) { super(title); this.series = new

I am getting counter values in one class using a thread and writing JFreeChart in another thread. While executing, it works alternatively, but only shows the graph at the end. It also displays the y axis label value as a Float but the actual retrieval value is int. How can I solve these issues? XYDataset Dataset; TimeSeries Series = new TimeSeries("Random Data"); Second sec = new Second(); ChartPanel CPanel; Value = Integer.parseInt(MySQLClass.Map_MySql.get(""+MainWindow.SelectedNode+"")); String CounterName = MainWindow.SelectedNode.toString(); Series.add(sec, Value); Dataset = new

I am using JFreeChart for the first time and I am using a TimeSeriesCollection() to create a TimeSeriesChart. My reslutset from the DB query is app. aroung 1000 records. I am using org.jfree.date.time.Minute.Minute(int min.....) object to add it to a TimeSeries object. I have a JFrame on which I add the ChartPanel directly. The user will provide new input parameters and reload the chart data with new dataset. So I clean up before every reload by calling the following in a method dataset.removeAllSeries(); chart.removeLegend(); chart.getRenderingHints().clear(); cp.getChartRenderingInfo()
