[Change range of y-axis]

Hi,

that works very fine.

 

For all a summary:

1.

create:

package tests;

 

import net.sf.jasperreports.engine.JRAbstractChartCustomizer;

import net.sf.jasperreports.engine.JRChart;

import net.sf.jasperreports.engine.JRChartCustomizer;

 

import org.jfree.chart.JFreeChart;

import org.jfree.chart.axis.NumberAxis;

import org.jfree.chart.plot.CategoryPlot;

import org.jfree.data.Range;

 

public class customizer extends JRAbstractChartCustomizer{

 

public void customize(JFreeChart jfreechart, JRChart arg1) {

// Get the plot

CategoryPlot plot = jfreechart.getCategoryPlot();

plot.getRangeAxis().setRange(10, 100);

}

 

}

 

2.: set it (see last post) in the chart the customizer class.

In my example you must write tests.customize

tests is the package name.

 

Thats all and you get a y-axis range from 10 to 100.

With the methods of plot (see above) you can change

different values of the chart

HI,

I have a custumizer extends JRAbstractChartCustomizer

and i try to use it with

JRDesignChart i = (JRDesignChart) (jdesgn.getSummary().getElements()[0]);

i.setCustomizerClass("customizer");

but i get

Exception in thread "main" net.sf.jasperreports.engine.JRRuntimeException: Could not create chart customizer instance.

 

i dont know i set the customizer class...

[Split a table with minimum 1 line content]

Hi all,

i have a Subreport. This includes in the columnheader the tableheader. In the detail band i have the table content.

Now i write JasperDesign.setsplitallowed(true);

 

If it works, i get sometimes in the bottom of the page ONLY the tableheader and in the next page i get again the tableheader with the content.

It is possible to avoid this.

If the tableheader is print in e.g. page 1 i will print minimum 1 line content...

 

Thanks

[problems to generate a subreport]

i try again:

e. g. i add in the detail band of my subreport the static text "detail" and in the page Header of my sub report the text "header". now i run the masterreport.

in the pdf file i see only the text "header". the information in the detail band are not print in pdf.

 

I think the reason is:

if i open in the masterreport the preferences of the subreport and see in the tab Subreport->connection/datasource i must add a connection. if it is empty the detail band are not print. what can i write?

 

Thanks and sorry about my perfect english

After i wrote "C:/Programme/JasperSoft/reports/a1.jasper" it works.

 

Now i have a new problem. i will display the detail datas of the subreport in the masterreport. But it shows all bands of the subreport without detail band. i need the detail band informations to print in the masterreport. what can i do?

 

Thanks
