Hi, I am using JFreeChart to display a dynamic TimeSeries chart in an applet. I want the user to be able to choose a time window for the data displayed. ie. Show the last Hour, Day, Month, or Year As data gets dynamically added I want to push any old data off the axis (at this point I don't know whe...

have you looked at the XYLineAndShapeRenderer? it has setShapesVisible(boolean) and setLinesVisible(boolean) methods.

my fault. I didn't realize that the month index started at 0

correction, Calendar is working for time periods larger than two weeks (approx?)... not sure why data disappears if time period is smaller than this...

yes I did. I also tried getting double values for the dates and using the setUpper/LowerBound methods. neither worked.

using Calendar instead of Date appears to be working though.

thanks for your suggestions!

hi, I have a chart in an applet which is obtaining data from our database. I am querying a time period of 7 days, 5 of which have data. If I let the chart auto range the data then it plots the 5 days along the x axis and the chart looks normal. However, if I specifically set the maximum and minimum ...

I was careful to reference the same version of the jfreechart jars (jfreechart 1.0.6, jcommon 1.0.10) from the applet as the ones available to the servlet (Originally the servlet had access to older versions) but this didn't help the problem. We have come up with a workaround but it's fairly messy (...

Hi, I have embedded a jfreechart applet in an html page. The applet is passed a serialized object from a servlet (connected to our database) which contains a TimeSeries. I am getting the following error: java.io.InvalidClassException: org.jfree.data.time.Second; incompatible types for field second a...

My apologies. That way was recommended to me. I am new to working with open source projects so I am not familiar with protocol or best practices. And yes, I need to access some of the private fields and modify methods in the ChartPanel class so copying the source seemed the easiest way to access the...

I am deploying my program in an applet and I have run into problems with overriding the ChartPanel class by placing a copied/modified version in an org.jfree.chart package within my project. Applets (in browsers) search the archive .jar files before searching files in your codebase, therefore openin...

I think I figured it out. I specified the location path for the java source attachment of the jar file and now I am able to open up the .class file and edit it. Is this what you meant?

I am using eclipse. so you are saying that if I change the source ChartPanel.java file the jar file will automatically update the ChartPanel.class file? do I need to import the ChartPanel.java file somewhere special in my eclipse project to work on it? sorry for all the questions. I am new to this o...

did you make these changes within the actual ChartPanel class or did you subclass ChartPanel to override the methods?...

again, thank you!

I am definitely going to take a look at this

just what I was looking for! thank you for sharing your code with us :) just one question. why did you choose to restore the original bounds and then zoom in n-1 times? did you encounter a problem in simply setting the axes bounds to the previous values? I have also been looking for a way to capture...
