Hi folks, 

In this tip, you would see how to convert sql rows into report columns. 
By default when you put text fields in detail band, you could see the report prints the query output in vertical order(row by row). There are some situations when your query results definite number of rows in output and need them to be displayed as horizontal view. 

In this case, usually one might think of cross tab implementation. This is fine upto some extent but working with cross tab is not always developer friendly hence instead of using it one can split the report into N number columns in reports properties and provide desired width for columns and then pull your fields one below to other. In the report advanced properties change Print Order property from Vertical to Horizontal and this would result converting rows output into columns that would look like a cross tab implementation. 

Design:

Query format/Sample query output

Hi folks, 

A table component in Jaspersoft requires a data set to be created and it can be done as usual but what if you want to display the calculations from table component outside of it's area on the same report or may be in some other report. 

We use "Return variables" concept on data sets that are being used by the components. For instance, below image is an example to display the avg shelf height and total shelf depth columns of table component outside of its(table) area. i.e, display the avg and total, say in "Title" band or say at some specific portion in Summary band. 

(Click on image to get best view of the content written over it)

To accomplish it, create variables in Dataset of the table component. 

For instance, Calculating Avg Shelf 

1) Create a variable in table data set, say "tableVarShelfHeight" of type Double in my case and the Calculation is Average and the Expression is $F{shelf_height} and IncrementType as None and Reset Type as Report.

2) Create a another variable in report variables, say "reportVarShelfHeight", of type Double and with Calculation as "No Calculation Function" and IncrementType as None and Reset Type as Report


3) Now, click on the Table component, and in its properties be on "Dataset" section and then click on the button called "Return Variables". In the pop-up window opened click on "Add" button to add then give the values for "From Variable" as "tableVarShelfHeight" and "To Variable" as "reportVarShelfHeight".

4) Now, from the report outline, and from the variables drag on drop the "reportVarShelfHeight" to the "Title" band and change its "Evaluation Time" as "Report" (by default it would be "None")

5) Follow, the same steps to create tableVarShelfDepth variable for total. 

This way, a calculation created in data sets of table component can be utilized on Title band of the same report. 

Want to look at the explained example instantly, copy and paste below JRXML in your test JRXML and observe the implementation.!

Hope it would be some help to you.!

Hi folks,

To merge the column headers in jasper reports table component, select the columns from "Column Header" section of "Table Outline"  and right click on them and then click on "Group columns".

It would add empty space on top of existing column labels and now you can keep an additional text field on top of the grouped columns which would look like a merged cell.

The outline of grouped column will be as follows.

Sample

Hi folks, 

In this page, you would see how to work with Horizontal bullet widget that should look like as shown in below sample output. 
Bullet widget takes two values.
1) Bullet Value
2) Target Value

Using this visualization one can plot a value against a target having different ranges.

Sample query for this visualization is : 
SELECT  47 AS value, 78 AS target FROM customer limit 1

In the widget properties provide these values as shown in below image.

For color range, provide min and max values as follows

red --> min=0 max=30
yellow --> min=31 max=45
green --> min =46 max=85
blue --> min=86 max=100

To get the exact look and feel as shown in top of the post, play with Widget properties
For instance, below image would give an idea


Save your report and preview the visualization. This way, the desired output can be visualized in jasper reports using Horizontal bullet widget.

Hi folks,

Did you ever had a need of displaying column chart without having category from database ?
Did you ever want to have 4 fields of query output to be plotted as bars ?

Here we go.!
Let's say the query output format to be plotted as bars as follows

Query:
SELECT 100 AS Measure1, 200 AS Measure2, 300 AS Measure3, 400 AS Measure4 FROM customer limit 1

Output:
Measure1   Measure2   Measure3   Measure4
100               200              300              400


Usually, in jasper column graphs to get bars we write query in such a way that the output should come as below

field1      field2
category 100
category 200
category 300
category 400
and it gets the same color (by default blue incase of highcharts bars) as it has category field. 

Incase of only measures, we add them as individual measures in the chart Measures section as shown in below image. 

and when we preview the graph it would get different colors for each of the bar as the graph would plotted based on series although we don't have any series or for empty series.

In this cases, if we want to apply conditional colors on Measures, it can be done in the Advanced properties of each of the measures.

for instance, to apply conditional color on Measure1,
1) Double click on Measure1
2) In the popped up window select "Advanced properties".
3) Click on "Add" button
4) Select "SeriesItemProperty" in the dropdown of "Contributer".
5)  Give "color" as name in "Property Name"
6) Now, observe there are 4 ways like "Use constant Value", "Use bucket value", "Use Measure Value" and "Use Expression".
  As we don't have to deal with categories, we ignore "Use Bucket Value" property section. In usual cases of conditional colors we work with it. And the constant value and Use Measure is not the scope. Ultimately we need to use "Use Expression" property. Let's click on it to open it's expression editor and write below code of "Measure1"

($F{measure1}>=00  && $F{measure1} <=100 )? "red": ($F{measure1}>=101 &&  $F{measure1} <=200 ) ? "yellow":($F{measure1}>=201 &&  $F{measure1} <=300 ) ?"green":"blue"

Repeat the same steps of rest of the measures i.e., for Measure2, Measure3, Measure4. 

Based on the values range we provide different colors as shown in above image. In this case, I used 4 columns to plot and whenever the values meets the range provided each of the bar display either "red", "yellow", "green" or "blue". 

Note that in the sample output below I made the query to get 4 different colors for 4 bars but if you have the same value for any other measures it would get the same color. (look at case2 or case3 sample outputs below)

Sample output: case 1
SELECT 100 AS Measure1, 200 AS Measure2, 300 AS Measure3, 400 AS Measure4 FROM customer limit 1


Sample output : case 2 
SELECT 100 AS Measure1, 200 AS Measure2, 300 AS Measure3, 100 AS Measure4 FROM customer limit 1
Sample output : case 3
SELECT 300 AS Measure1, 200 AS Measure2, 300 AS Measure3, 300 AS Measure4 FROM customer limit 1
I hope this helps someone in community.!

Hi folks, 

In this post, you would see how to work with SparkLine widget in Jaspersoft reports. I'd be explaining core points as steps in this article. 

The aim of the post is to develop a report which would have below look and feel with sparkline widget.


1) Write below query in Query editor of the JRXML

Sample query:
(SELECT 'text' AS text1, 'text' AS text2, 10 AS value1, 20 AS value2, 30 AS value3, 40 AS value4,  1234 AS value FROM customer limit 1)
UNION ALL
(SELECT 'text' AS text1, 'text' AS text2, 34 AS value1, 54 AS value2, 12 AS value3, 78 AS value4,  1234 AS value FROM customer limit 1)
UNION ALL
(SELECT 'text' AS text1, 'text' AS text2, 43 AS value1, 76 AS value2, 21 AS value3, 40 AS value4,  1234 AS value FROM customer limit 1)
UNION ALL
(SELECT 'text' AS text1, 'text' AS text2, 40 AS value1, 20 AS value2, 12 AS value3, 43 AS value4, 1234 AS value FROM customer limit 1)
UNION ALL
(SELECT 'text' AS text1, 'text' AS text2, 65 AS value1, 21 AS value2, 87 AS value3, 45 AS value4,  1234 AS value FROM customer limit 1)

Sample output of the above query:

2) Drag and drop SparkLine widget from the "Widget Pro" section of the Palette. 

3) Our goal to get the spark lines in details of the report, so the report design should look like below 
i.e., keep spark line widget graph in detail band

4) Edit widget properties to provide the values for lines plotting on visualization. Usually, in a normal line chart we take category and values to plot lines but in case of spark lines we take directly the numeric columns say  value1, value2, value3 and value4 from the sample query. 

IMP NOTE : Ensure that Reset Type = None in "Widget Data" section of "Dataset"

IMP NOTE: Take a look at the Basic and Advanced properties of Widget graph to get the exact look and feel as shown in this article in the top image. 

5) Save the report and publish it to jasperserver and you would be able to see the report output as shown in very first image of the post.

Hi,

Problem Statement : 
How to remove yAxis values from  a highcharts column or bar graph ?
Solution: 
1) Navigate to the Advanced properties of the column graph.
2) From the list of folders in the advanced properties choose "yAxis" and expand it.
3) Scroll down till you find again a folder called "lables".
4) In the labels folder select "format" property (by default it would have default value as {value}) and double click or click on modify button.
5) Change the value of it from {value} to {}
6) Save your report and preview the the visualization
 


Output should look like as below


I hope this helps someone.

Hi,

Group count calculation can be done as follows in jasper reports.

Scenario : 
Report Design:
<GroupNumber>  <GroupBand>
                             <detailband>

Example: 
   IamGroupValue1
         row1_value
         row2_value
         row3_value
2    IamGroupValue2
       row1_value
       row2_value
  IamGroupValue2
      row1_value
      row2_value
      row3_value
      row4_value
...
...
...

Steps:
1) Create your group (lets say Group1 , give the field value by which you want to group by)
2) Observe variables - there it creates a variable called "Group1_Count"
3) Create a new variable of Integer type , let say : groupCount
4) Give below expression for the groupCount variable
      $V{Group1_COUNT} == 1 ? ($V{groupCount} + 1) : $V{groupCount}
5) Put Increment Type= [Group]Group1 and Reset Type =Report and Initial Value=1
6) Pull this variable onto the group header where you want to get it.
7) Run the report observe the group count in output.
