Hi,

 

How do you add the chart? Using an image element?

Or using a chart element from JR?

You should post here the JRXML fragment that introduces the chart in the summary.

 

In the meantime, maybe you want to take a look at the samples provided with the JR project distribution.

There are two that might interest you inside /demo/samples/charts and /demo/samples/jfreechart.

 

I hope this helps.

Teodor

Hi,

 

If you have other questions, please post them o separate message threads. Do not use the same thread for all your questions because the thread would become a mess and others cannot make use of it.

 

Now, going back to your chart quality questions. It is blur because you generate the chart as image and then include the image in the report. And if you zoom, the image does not scale very well. This is normal.

The solution has already mentioned to you. Look at the /demo/samples/jfreechart sample provided with the project and you will see that we are wrapping the JFreeChart object into a special JRRenderable implementation that makes sure JFreeChart will draw the chart directly on the graphic device at runtime as a SVG, thus preserving chart quality.

 

I hope this helps.

Teodor
