[Waterfall chart in Jasper]

Is there a way to draw water fall charts in Jasper soft studio v 5.6?

[Export Jasper Report to pptx -Jfreecharts look blurry]

I am using JasperSoft Studio v5.6 to develop reports. I need to export the reports to Powerpoint. I tried using JRPptxExporter but the jfreecharts appear blurry. Need to know if charts (Jfreecharts) can be exported as actual Power Point objects. If not is there was way to export them as sharp clear images.

Please let me know all the options available

[add more pages to jaspersoft studio]

Actually I did it by creating more detail bands within the main report.

[Place subreport just after the output of above subreport]

I have 2 similar subreports. The design of the subreport is as shown below. The detail band iterates depending on the number of rows returned from the database. I have specified the height of the subreport as 792 pixels. This could have 3 to 8 rows displayed.

 

Now I want to display the subreports one after another as shown below without any white space in between them. 

My question is how to place the 2nd subreport so that it appears just after the 1st subreport (keeping in mind that 1st subreport could have 3 or more rows )and without any spaces between them

[Return field value from dataset to main report]

I need to hide a element on the main report based upon a field (say X) defined in the new dataset created on the main report. But the problem is, I cannot hide this element as this field X is not appearing under print when expression. Only fields identified on the main report query are showing up here.

So how do I hide this element now? 

Note, I cannot add the query from the dataset (which retrives this field X) to the main report query as that query already returns some other data from the DB.

[Dynamically adjust the width of subreport based upon a parameter/field]

I have a subreport whose width needs to change based upon a parameter/field. (Example: if value of Parameter/Field= 1, then subreport display should be full width else half width of page). Please let me if this is possible. Thanks.
