I had to put a JFreeChart in a PDF that used tables a couple of weeks ago and couldn't
find any good instructions or code examples. Here's a sketchy outline of what I did
that worked -- of course this can be improved upon, but it does show how I used a
ByteArrayOutputStream to get the image (which is what I think you were trying to
determine how to do):
Open a PdfWriter and open the document
Instantiate a table, cells and add cells to table
When you're ready for the chart, create the chart object:
//get the data for the chart
CategoryDataset data = geteBarChartData(bemsid);
//get a chart rendering object
ChartRenderingInfo info = new ChartRenderingInfo(new
StandardEntityCollection());
//Make the chart
JFreeChart chart = makeChart(data, bShowLegend);
//set up the image size for the chart
int width = 550;
int height = 250;
//open a byte array output stream (baos)
final ByteArrayOutputStream baos = new ByteArrayOutputStream();
//use a utility that writes the chart to a JPEG using the
ByteArrayOutputStream
ChartUtilities.writeChartAsJPEG(baos, chart, width, height, info);
//Instantiate an image using the ByteArrayOutputStream
Image barChartImage = Image.getInstance(baos.toByteArray());
//flush and close the stream
baos.flush();
baos.close();
//now I needed to add the Chart to a cell in a table
detailCell = new Cell();
detailCell.setColspan(5);
detailCell.setBorder(cellBorder_);
detailCell.setHorizontalAlignment(Element.ALIGN_LEFT);
detailCell.setVerticalAlignment(Element.ALIGN_TOP);
//add the chart to a table cell
detailCell.add(barChartImage);
//add the cell to the table -- or to the document if that's what you need to do
table4_.addCell(detailCell); //bar chart
Hope this helps!

I suppose you are doing it through Graphics2D. Write the chart to a = template and
wrap it in an Image.

Subject: [iText-questions] Graphic and table in PDF
I am trying to have both a graphic and table in a pdf, thus far I can = only get one
or the other. I am using JCharts to create the graphic and the iText Table for the
text. Has anyone done this successfully? If so I = would appreciate any help you can
provide. I have been working on this for a = few days and tried incorporating the
example from the tutorial (Ch 10) but I can't get it to work.
Thank you,
