Hi, I have noticed that as the number of points increases, the dashing line effect gets lost completely (I am using the latest JFreeChart). The reason for this problem is that dashing effect occcurs only between points not throughout the whole line. Thus, as the number of points increase, the effect...

Thanks skunk for your reply. Basically, what I did was that I implemented my renderer that extends XYLineAndShapeRenderer. I overrode drawSecondPass ( a protected method which is responsibly for drawing shapes) and I put my logic in that method. The code is: package com.telus.insight.graph; import j...

Hi, I am using the latest JFreeChart. In my line graph, I want each line to start and end with some shape. I did some research in the news group and I found that I have to implement my own renderer to do this. So, My questions are: 1) How would I start about doing this? 2)I already noticed that Jfre...

Look at the web samples in jfreechar website. There is a war file and source code there.

Hi, I have JFreeChart 1.0.1. I want to customize the drawing of legend items. I did the research in the news group, but all the postings talk about re-implementing the draw method in Standard Legend class. I can't find that class in JFreeChart 1.0.1. I know that I have to re-implement some draw meth...

Here is the code for this problem. I had to re-implement drawLabel method to fit my requirements. I wrote a sample demo for it. The code is below package demo; import java.awt.*; import java.awt.geom.*; import java.text.*; import java.util.*; import java.util.ArrayList; import java.util.List; import...

1) I have a number axis. I am using the latest jfree chart. Basically, my axis label is two long and I would like to split into three lines. I did the research in the newsgroup and I found that it is not implemened in the older versions. I tried playing with the latest version to no success. Could a...

For people who may have a similar problem, I have posted my solution to this problem. Basically, the tooltip hotspot is collected from the entities, which are retrieved int the method body of a drawItem, which is located in a renderer class. The piece of code that does this retrieval is: // add an i...

Pretty much every renderer has setToolTipGenerator (generator) method. Basically, you would implement your own class that overrides a generator and call setToolTipGenerator on your class. For example, XYItemRenderer has setToolTipGenerator (XYToolTipGenerator generator) So you would implement your c...

Hi,

I have implemented a stacked bar chart with very thin bars. Since the bars are very thin, the tooltip hotspot is very thin. I would like to increase it. Is there any way to this nicely?

Thanks,

Hi, I have noticed that (sun.dc.pr.PRException: endPath: bad path) exception gets thrown every time you zoom (5-6 times at least) in on the chart. This is a java defect. Supposedly, it is fixed in 5.0 version. In any case, I wrote my customrenderer that fixes this issue. I have noticed that some peo...
