Calculating aggregate on data cube totals

April 24, 2013, 1:05 pm
$

Hey BIRT folks,

I have a report I'm working on, where I have a crosstab displaying 3 columns per column grouping. In the dataset feeding the data cube, I am dividing the first column by the second one, and outputting this in the 3rd column of the crosstab:



At the bottom of the crosstab, I have the totals of the first and second columns (Target and Actual). What I can't figure out is how to get that first column total divided by the second column, and to show it in the 3rd column in the summary row. I've tried to do an aggregation in that cell, but I only am able to access a single expression in the table (I can't write a custom expression to divide one column by the other one).

Thanks for the help!

I have one table in the report with the fixed width set to 250px. The HTML output has a main table with a width of 8 inches. How can I change the main table width to be the same size as the table in the report?

Note: The HTML page has a white space area to the right of the inner table.

Thanks for your help.

Multi column report

I'm running the latest version of BIRT (3.7.1). I've been trying to set up a multi-column report, but I cannot figure out how to do it. I've set the columns property on my master page to 2, but when viewing the report, I only see only column. I see that this version of BIRT is supposed to support columns. What do I need to do?

how to use com.itextpdf.text.image to generate pdf report

April 24, 2013, 4:55 pm

I have some dynamic JFreeChart charts which need to be inserted into pdf report
I used iText before. the code like the following:

private Image genJfreechartImage(PdfTemplate tp, JFreeChart chart, float width, float height)throws BadElementException, DocumentException{
Graphics2D g2d = tp.createGraphics(width / 40, height / 40, true, 0);
Rectangle2D r2d = new Rectangle2D.Double(0, 0, width, height);
AffineTransform affineTransform2 = AffineTransform.getTranslateInstance(0, 0);
affineTransform2.scale(0.025, 0.025);
g2d.transform(affineTransform2);
g2d.transform(AffineTransform.getTranslateInstance(0, 0));
chart.draw(g2d, r2d, null);
com.itextpdf.text.image img = Image.getInstance(tp);
g2d.dispose();
g2d = null;
float pageWidth = (float) (PageSize.A4.getWidth() * 0.9);
float percentage = (pageWidth / img.getWidth()) * 100;
img.scalePercent(percentage, percentage);
return img;
}

in this method, I got the vector image in pdf which will not be distorted after zoom in, the pdf file size is small and the generating report time is quick

Now I use birt-4.2, I use dynamic image which takes byte array as source, so my code is:

public byte[] getByteArray(List<ChartData> chartDataList, int width, int height, boolean isDualAxis) {
byte[] png=null;
BufferedImage objBufferedImage = new BufferedImage(480, 320, BufferedImage.TYPE_USHORT_555_RGB);
Graphics2D g2d = (Graphics2D) objBufferedImage.getGraphics();
Rectangle2D r2d = new Rectangle2D.Double(0, 0, 600, 400);
AffineTransform affineTransform2 = AffineTransform.getTranslateInstance(0, 0);
affineTransform2.scale(0.8, 0.8);
g2d.transform(affineTransform2);
g2d.transform(AffineTransform.getTranslateInstance(0, 0));
jfreechart.draw(g2d, r2d, null);
g2d.dispose();
g2d = null;
ByteArrayOutputStream bas = new ByteArrayOutputStream();
try {
ImageIO.write(objBufferedImage, "png", bas);
png=bas.toByteArray();
bas.close();
} catch (IOException e) {
e.printStackTrace();
}
return png;
}

in this method, the image in pdf is distorted after zoom in, the file size is bigger and the generating time is long

Is there a way to take com.itextpdf.text.image as the source for dynamic image in birt? or is there any other solution? If I want to edit the birt source code, can you give me some guide?

thanks very much.

Hi All,

Greetings of the day,

We are facing the following error(See the attached file) while deploying the report in our application.
Earlier we used the normal jdbc connection for creating the report and it worked fine from eclipse as well as from our application. Since we have several report we change the jdbc connection to Connection Profile. After changing the data source settings to connection profile it is not showing data while running from the application. how ever it is running properly from eclipse.

We are using Window 64 bit with Birt 4.2 with Cordys(BPM Tool) application.

Thanks in advance.

Is it possible with Birt reports to link a checkbox parameter to a java class that is triggered by checking or unchecking the box? I'm looking to have the ability to set some background properties based on this action before I submit the parameters to run the report.

Any examples or online instruction you can point me to?

Thanks for the help!

Hi,

We are using Birt Report Engine in our Java application to print reports to pdf.
But Task.run is very slow. it takes 30 seconds to build a report of 3 pages for the first time.for the second time it takes only 2 sec to generate the report.

Is there any way to minimise the report generation time when we print it for the first time?

Please let me know if there is any way to optimise the report engine.

I have attached birt engine.

We have used scripted data source and BIRT Designer Version 3.7.2.v20120213.

CrossTab cell formatting?

April 25, 2013, 2:47 am
$

Hi,

I have report with several graphs and one crosstab. The layout of the crosstab is as follows

ColumnName[colIndex]

DataFrom | DataType[rowIndex] || Data

It should look something like

Monday Tuesday ......

Paris Furniture 1200 2000
Candies 120 220

ROI 5.5% 7.0%


London Furniture 2200 2700
Candies 220 320

ROI 6.5% 8.0%

etc

The data is produced by a database query and all computation is done (in Java) before pushing the data to the
report.

A line of data to the report looks like:

{dataFrom:sales, dataType:candies, columnName:Monday, columnIndex:1, data:1200,.....}

Everything works okay, for the exception of the rows (and a specific columns) containing percentages. All data, including percentage is pushed in the double datatype from Java, i.e. 0.055 for 5.5%. The report design data type is decimal.

The requirement of the rows and columns containing percentages is that its shows the %-sign and if value is positive the color of the cell/number should be green, if negative then red.

I have managed to get the colors on the correct row and column cells containing the percentages. However I am unable to get the % sign into those same cells.

In the crosstab script I have 
function onCreateCell( cellInst, reportContext )
{
if( cellInst.getDataValue("columnName")=="ComparedToPreviousMonth" 	|| 
cellInst.getDataValue("dataType")=="ROI")
{	
	

// cellInst.getStyle().setNumberFormat("##.##%");
			
if(cellInst.getDataValue("data_TypeGroup/dataType_columns/columnName") < 0) 
cellInst.getStyle().setColor("RGB(253,120,120)");
	
if(cellInst.getDataValue("data_TypeGroup/dataType_columns/columnName") > 0) 
cellInst.getStyle().setColor("RGB(0,139,8)");


}

}

As I said the coloring works correctly for the given rows and columns. But if I remove the comment on the line with setNumberFormat, then every cell in the whole crosstab gets formatted with % and extra zeros.

It appears that setNumberFormat somehow affects every cell while the coloring works as expected, for the specified row and column cells.

How should I solve this problem?

Two questions about required parameters

Hi all,

I have two questions about required parameters.

1. Is it possible to have "either/or" required parameters? Eg. the user needs to specify parameterFoo OR parameterBar for the report to run.

2. When using cascaded parameters, is it possible to keep the top level parameter optional, but make the second level parameter required? So if your parameters are paraFoo -> paraBar, you don't have to specify a paraFoo, but if you do, paraBar is required.

Thanks so much!

Error with BirtDateTime

When using the BirtDateTime in our reports we sometimes get the following error.

Data (id = 363):
+ A BIRT exception occurred. See next exception for more information.
Error evaluating Javascript expression. Script engine error: ReferenceError: "BirtDateTime" is not defined.
Script source: null, line: 0, text:
BirtDateTime.now()



Here is what this looks like in the report designer.
<data id="363">
<property name="marginLeft">2pt</property>
<structure name="dateTimeFormat">
<property name="category">Long Date</property>
<property name="pattern">Long Date</property>
</structure>
<property name="display">inline</property>
<list-property name="boundDataColumns">
<structure>
<property name="name">Column Binding</property>
<text-property name="displayName">Date</text-property>
<expression name="expression" type="javascript">BirtDateTime.now()</expression>
<property name="dataType">date</property>
</structure>
</list-property>
<property name="resultSetColumn">Column Binding</property>
</data>



Any ideas as to why we are getting this error sometimes with the date? When we get this error all the other fields populate correctly except the date is left blank.

Thanks for any help!
