Use Case : Usage of two or more different data sources in Single Report

Hi Folks,

 (Theory will update here later tomorrow or so, meanwhile use the JRXML to view the output)

Data bases used : 
1) MySQL , sakila db
2) PostgreSQL foodmart db.

Sample output



Copy paste this code in your JRXML source code and observe the "Dataset1" data source parameters and connections as well the main report query and its connection.

How to get the same output in the Jasper Server ? 
By creating Virtual Data source defined in Jasper Server and pointing out the report to use this data source.

NOTE : Virtual Data source concept is an enterprise feature in Jaspersoft BI.

Tip : Set RoundingMode.DOWN for Double/Big Decimal types in Jasper Reports 6.x


This post will give you the inputs on how to get the non rounded(exact values) after decimal points for Double or Big Decimal types in Jasper Reports/(Java).

There are situations in reporting to display the exact values after decimal point for some purpose.

For example : 
4.53455 should get printed as 4.53
0.234 should get printed as 0.23,
0.057 should get printed as 0.05 (but not 0.06 by rounding)
0.389 should get printed as 0.38 (but not 0.39 by rounding)

The above implementation in  JAVA is pretty easy but in jasper it would be a tricky as shown in below examples.

Examples : 
new BigDecimal(new Double(0.05592538471251264)).setScale(1, RoundingMode.DOWN)

new BigDecimal(new Double(1.9596988841721044)).setScale(1, RoundingMode.DOWN)

new BigDecimal(new Double(91.0)).setScale(1, RoundingMode.DOWN)

new BigDecimal(new Double(.0)).setScale(1, RoundingMode.DOWN)

Sample output :

100% horizontal stacked percentage bar chart example in Jasper Reports 6.x (or) How to get %'s on stacks, color for data values

Hi Folks,

This post will teach you how to work with 100% horizontal stacked highcharts bar chart in Jasper reports and how to work with Advanced properties of it.

I hope this would help some one in saving their(s) time.

Software used to test this example : 
1) Jasper Design Studio 6.1
2) foodmart database of postgresql
3) Jasper Server 6.0.1 professional & Mozilla firefox web browser.

Sample output of the report : 
I hope you have already knew how to create a new report hence skipping some basic steps and concentrating in explaining core parts.
1) Sample Query Design
SELECT
    occupation,
    state_province,
    SUM(num_cars_owned) cars
FROM customer c
WHERE state_province IN('CA','WA','OR')
GROUP BY
    occupation ,
    state_province
ORDER BY
    occupation,
    state_province

2) Sample output of the query 

3) Drag and drop "StackedPercBar" chart from HTML-5 charts component from Palette section.

4)  Right click on it get the chart properties.
   In chart data section & under configuration tab give below.
Category : $F{occupation} (of java.lang.String type)
Series : $F{state_province} (of java.lang.String type)
Measures : $F{cars} (of java.lang.Integer type)

5) Come back to the chart properties and click on Advanced Properties and click on "Add" button to add below properties.

plotOptions.series.dataLabels.enabled = ture
(Tick the check box) - to enable the values
plotOptions.series.dataLabels.format =" {point.percentage:.0f} % "
(tick the check box) - to get the %'s
plotOptions.series.dataLabels.color = #FF0000
(do not check the tick box) - to get the colors for values

See below image for accuracy 


6) Save the report, publish it the server and have preview. Output should look as shown in first image to this post.

JRXML code : (copy paste the code to get the same copy in your JRXML source , note that it will only work in professional studio or iReport).

Tip : Highcharts advanced properties for bar chart - Display vertical labels on bar

Hi folks,
Here is the small workout. Hope you may find it useful.

Requirement is subjected to this post. :-)

Steps : 
1) Right click on the bar chart ( Column vertical bar chart).
2) Click on "Show Advanced Properties"
3) Click on "Add" button to add below 3 properties.
plotOptions.series.dataLabels.enabled = true
NOTE :
# no double quotes for true & check tick mark of Use an expression
# This property enables the data values to show on bar(values would be outside of bar).

plotOptions.series.dataLabels.rotation= new Integer(90) 
NOTE:
# check the tick mark of Use an expression
# This property rotates the data values vertically on bar.

plotOptions.series.dataLabels.y= new Integer(-20) 
NOTE:
# check the tick mark of Use an expression
# This property is used to give the distance to the value vertically from the bar top. 

Sample output :
