Using conditional formatting in iReport

由 断了今生、忘了曾经 提交于 2019-12-07 14:58:59
问题 I have a report providing a table of data. The report works great so far. Now I need to colourise some cells according to their content value. I used to include the colour scheme in the Text Field Expression, for instance: ($F{MyBooleanValue}==true)?"<style backcolor='green'>PASS</style>":"<style backcolor='red'>FAIL</style>" That works but it is quite dirty and a hell to manage and re-use. So I turned to the Conditional formatting feature. I defined a based style called Colourised . Then two

Use a variable calculated average of a specific field in the Title band

由 放肆的年华 提交于 2019-12-07 14:47:59
问题 I have a variable which stores the calculated average of a specific field. Is there any way to use this variable in the Title band? When I try to do it, I just get null in the Title but the correct value in the Column Footer . The only other possibility for this I see is, to precalculate it in Java and pass it as an argument, but I'm trying to avoid that. I'm using JasperReports and iReport in version 3.7.4. 回答1: The Variable and the Text Field both have the property Evaluation Time . Set it

Chart with multiple series on each row

由 偶尔善良 提交于 2019-12-07 13:28:54
问题 I'm trying to do an iReport chart with this table name|totalcalls|handled|abandoned|rejected customerservice|300|100|100|100 itsupport|500|300|100|100 The idea is that there should be 2 charts in this case, that was easily solved by putting the chart into the details row. But I cannot figure out how to make iReport treat the 3 last columns (handled, abandoned, rejected) as different series. Ideally I want to do a stacked barchart that looks like this: customerservice|-100-|-100-|-100-

Trend analysis using iterative value increments

由 坚强是说给别人听的谎言 提交于 2019-12-07 07:29:06
问题 We have configured iReport to generate the following graph: The real data points are in blue, the trend line is green. The problems include: Too many data points for the trend line Trend line does not follow a Bezier curve (spline) The source of the problem is with the incrementer class. The incrementer is provided with the data points iteratively. There does not appear to be a way to get the set of data. The code that calculates the trend line looks as follows: import java.math.BigDecimal;

Displaying tables below each other in JasperReports

由 雨燕双飞 提交于 2019-12-07 05:08:50
问题 I have to create a report where several tables are diplayed below each other. Each table gets its data from a SubDataset and contains none, one or more rows. For the first version of the report, I've simply ignored the possibility of a table having no rows and put all tables below each other, each with the height of 1 row. The idea was, that if there is more than one row, the table will grow in height, which seems to work fine. I've given the first table a fixed position and set all

I want to include the .jrxml file in my NetBeans swing project. I use NetBeans 7.0.1 . I created a package inside source package called "rep" and created a simple .jrxml file called "rp.jrxml".

Jasper Reports datasource for JSON data

由 孤者浪人 提交于 2019-12-06 19:33:29
问题 Anyone know of an open source Jasper Reports DataSource implementation that can handle JSON data? I'd like to utilize JSON data from a RESTful API in some custom reports. Before I build it myself, I figured I'd check if something already exists. 回答1: There is a JSON Datasource in Jasper 5.0.1. I think it is new with V5. http://jasperreports.sourceforge.net/api/net/sf/jasperreports/engine/data/JsonDataSource.html The API doesn't tell you much. Haven't found documentation for it yet. The

Modularization of Jasper reports: Pass data source to subreport without unnecessary db roundtrips?

由 我的梦境 提交于 2019-12-06 15:54:14
问题 In this thread how-to-pass-main-report-data-source-to-subreport-jasperreports it is stated that there may be problems with subreports on reusing an existing master reports data source . It says the subreport may close the datasource prematurely (before other iterations calling the subreports may be processed). It seems that this may be my problem because the report is always generated (without an error) ... ok: using the connection from the master report (thus each time executing the query
