OK -
Reading through the voluminous api of jfreechart I found a different
method... getImageMap
which thankfully returns a String.

I am using jfreeChart for my charts... great api... however, I am
trying to do
a clickable graphic.
Here is the sample code:
final File file1 = new File("piechart100.png");
ChartUtilities.saveChartAsPNG(file1, chart, 600, 400,
info);
// write an HTML page incorporating the image with an
image
map
final File file2 = new File("piechart100.html");
final OutputStream out = new BufferedOutputStream(new
FileOutputStream(file2));
final PrintWriter writer = new PrintWriter(out);
writer.println("<HTML>");
writer.println("<HEAD><TITLE>JFreeChart Image Map Demo
2</TITLE></HEAD>");
writer.println("<BODY>");
ChartUtilities.writeImageMap(writer, "chart", info);
writer.println("<IMG SRC=\"piechart100.png\" "
+ "WIDTH=\"600\" HEIGHT=\"400\"
BORDER=\"0\"
USEMAP=\"#chart\">");
writer.println("</BODY>");
writer.println("</HTML>");
My question is how do I do the writeImageMap so that it will instead
of
being written to
a file it will write to ??? NSData???
How about substituting the BufferedOutputStream with an
ByteArrayOutputStream? Then, after calling
ChartUtilities.writeImageMap(), call
ByteArrayOutputStream.toByteArray().
Getting to an NSData is as easy as `new NSData(
ByteArrayOutputStream.toByteArray() )`.
