Hello, I am working on a report that I would like to have include a Barchart. An approximate example of the data I am reporting on is: Clinc,VisitID,Decline,Improvement 1 , 1, , 1 , 2, -0.08, 0.11 1 , 3, -0.09, 0.12 1 , 4, -0.05, 0.10 1 , 5, -0.03, 0.06 1 , 6, -0.05, 0.10 I am setting the series expression to Clinc. The Category expression is the VisitID. What I want to have in the value expression is both the Decline and the improvement values. However when I try to put both of these values in as value expression I am getting an error evaluating the expression. The expression I am trying to ues is shown in the code. I have included a sample that shows what I am looking for. How would I write the value expression to get the results I am looking for? Thanks in advance Eric Lommatsch Code:$F(Decline)$F(Improvement)

Never mind, I just found the setting I needed to change. It was the Dataset reset type.

Hello, I am trying to create a report with a chart that will show the scores for patients in a time series. What I want to do is have a report where each page will represent one patient over the visits that represent an individual episode. I want to display the data at the top and have a chart at the bottom of the page that shows only the data for an individual patient. I tried creating a report where information is grouped first on the patient ID and then on the Episode ID. I then placed a line chart in the group footer for the report to have the chart show the results only for the patient that is shown on the page. However when I preview the report what I am seeing in the chart is that chart is attempting to show all 800 + records at one time. I have attached a sample of what I am getting when I preview the report What settings do I have to change so that the chart will only evaluate data from the current Group?

Hello Matt, I am also looking at wanting to set theb Min and Max values on the range axis. I am using iReports version 3.5.3 and when I try to enter the expressions I want as my min and Max values I am getting a compile error when the expressions is evaluated. What would be the correct expression for a min value of 0 and a max value of 150? Eric Lommatsch

Hello, I am working on a project where I am creating a line chart that will show patient self evaluation scores over a period of visits to a doctor. One of the things the client would like to have is for each datapoint in the chart that shows the value of the score at each datapoint. I have set the Label expression to the column from my query that holds this value. However when I run a preview of the report I am not seeing the labels. Is there some other setting that I need to set to have the labels show up on a line chart? Or can I not use labels in a line chart? Eric Lommatsch Post Edited by ericlomm at 10/01/2009 21:04

I figured out how to get things to work, but when I ran the ant scripts that did not work.

Hello, Between having to deal with paying work and other internal priorities I have finally been able to get to the point where I have jasperreports setup to start learning how to use it. However when I started going through the instructions on the page http://jasperforge.org/website/jasperreportswebsite/trunk/getting.started.html?group_id=252 to run the Barbecue application when I get to the command 'ant compile' I am getting the following error. ( Have only added the line of information from the error) java.lang.NoClassDefFoundError: org/eclipse/jdt/internal/compiler/ICompilerRequester I have found what appears to be the .jar file that this error message is pointing to, but when I try and add this to my CLASSPATH I am running into a length limit on my class path and I can add 'C:jasperr" to my classpath. it won't let me add anything else to my classpath. is 2048 chars really the limit on the classpath? How can I fix this? Where would I find the file that the program is looking for in this case? Eric Lommatsch Post Edited by ericlomm at 08/28/2009 21:38

teodord Wrote: Hi, For JAXP and JDBC, newer versions should be fine. For JAXP, if you take the Xerces JARs from the /lib directory of the JR project distribution package, you won't have to worry about anything. In a Java classpath, JAR files have to be specified individually, and not by root folder. So you can put them anywhere, as long as you have to specify each file individually. Folders in classpath are only for introducing folder hyerachies containing unpackaged *.class files. I hope this helps. Teodor On the JAXP and JDBC, that was what I had figured, but I wanted to make sure. I will make sure that all of the JAR files are specified individually when setting things up. I don't normally work with Java programs so a lot of this Java stuff is new to me. Thanks for your help.

Hello all, I am trying to setup Jasper reports for the first time and in looking at the requirements Page I have had a few questions come up that from my reading I can't find the answer to. First, for the JRXML it mentions that I need the "JAXP 1.1 XML Parser" However when I do a search for the package I am only able to find the "JAXP 1.3 XML Parser" which is a newer version. I see that on all the other packages it says that I can use version "x.x or Newer" but it doesn't say that for the "JAXP 1.1 XML Parser" Can I use a newer version? Also the version of the JDBC that it mentions there is also an old version, Can I use newer version of this? if so might be helpful if the requirements page said this. Finally, and maybe this is more of a java question then a Jasper Reports question. I am installing Jasper Reports on windows. Do I need to add classpath information for each of the componets that is listed in the requirements for Jasper reports to find them? Or if I create a directory C:\Jakarta and put each componet in a seperate directory Under that, can I just have a classpath of C:\Jakarta? I know these are probably simple questions for people who work with Jave all the time, But I am not a Java Programmer. Eric Lommatsch
