jfreechart

I would like to know, if it is possible to set the both parameter as date, which in this example it take the first parameter as comparable and the second as double. But i want the double to be displayed as date. Is there a class that can be used. If not Is there other way to display both as date. For instance i need both the x-axis and y-axis as date. For the data.addValue("8/4/2012" ,7.0) I want it like this ("8/4/2012 20:06:02" ,"8/5/2012") --> Is it possible with the graph below. Thank you in advanced. public class Example1 { public static void main(String args[]){ DefaultKeyedValues data =

Can we implement the pan functionality as a mouse drag event in JfreeChart? Right now I press CTRL and drag my mouse to pan a chart. I want to implement the pan functionality just by dragging the mouse. Is that possible ? It is apparently impossible to change the modifier key with the current JFreeChart API, as discussed here (but it is in the pipeline). However, everything is there to pan a chart programmatically, so you could try the following: Add a MouseMotionListener to your ChartPanel to track mouseDragged() events. From these events, compute the requested movement of the chart. Call

As shown in image the graph is from line y=0, here i want to plot a graph from y=50, how can i specify this in JFreeChart ? Here is Some Code: public class Profile { double last=0; public void generateProfile(int[] pointValue,double[] distance){ ArrayList pv=new ArrayList(); ArrayList dist=new ArrayList(); pv.add(pointValue); dist.add(distance); for(int i=0;i<pv.size();i++){ System.out.print(pointValue[i]); } for(int i=0;i<dist.size();i++){ System.out.print(distance[i]); } XYSeries series = new XYSeries("Average Weight"); for(int i=0;i<pointValue.length;i++){ if(pointValue[i]!=0){ series.add

I have one a jfree chart which I can generate everytime I run the code. Now i want to override few more spider graphs on the same chart. please help me how to do that Above this i need to add one more spider chart using jfree. Here is my code for doing this chart. package com.rectrix.exide.pdfbox; import java.awt.BasicStroke; import java.awt.Color; import java.awt.Dimension; import java.awt.Font; import java.awt.GradientPaint; import java.awt.Paint; import java.awt.PaintContext; import java.awt.Rectangle; import java.awt.RenderingHints; import java.awt.geom.AffineTransform; import java.awt

I have a StackedXYAreaChart similar to the one below: On the Y-axis, instead of the tick units shown ( 2.5 , 5.0 , 7.5 , 10.0 , etc.), I have the following: 100,000 , 200,000 , 300,000 , 400,000 , etc. These represent Bytes, just like the one above. My question is: is there a way I could format these tick units such that they represent Kilobytes, i.e. 100 , 200 , 300 , 400 , etc. or even Megabytes, i.e. 0.1 , 0.2 , 0.3 , 0.4 , etc.? I don't want to display 10 MB as 10,000,000 on the Y-axis. Thanks! trashgod The static factory createStackedAreaChart() instatiates a NumberAxis for the range. The

I have a question about JFreeChart : Is it possible to change the PlotOrientation of a BoxAndWhiskerChart to horizontal? I have a histogram, and I want to add a BoxAndWhiskerChart below. I need it horizontal so I can use the same axis scale. I tried to change the orientation in the Plot and ChartPanel . trashgod @Catalina Island shows the correct way to change the PlotOrientation here , but you may run into a bug in the BoxAndWhiskerRenderer shown below for PlotOrientation.HORIZONTAL . Note the truncated line on the lower whisker. The problem is here in drawHorizontalItem() : g2.draw(new

I have a traditional Java swing application (extends JFrame and has a main class) that uses JFreeCharts for some charting functionality. I have recently seen JavaFX and think these charts look alot refresher and will give my users a better experience. I wish to embed a JavaFX chart scene into a jInternalFrame (which in turn is called from my jDesktopPane). I have followed a simple tutorial on how to create both a javafx application and a javafx chart but I am stuck on to how I get the scene inside my existing code. One example I have been through shows me how to achieve this but means
