Re: Image genration using jcchart & passing it to HTML client.
I used a server-side graphing/charting tool from Visual Engineering (www.ve.com). It worked very well for this requirement.

Re: Image genration using jcchart & passing it to HTML client.
Keep in mind, GIF is a proprietary format, so you can't "legally" create a gif image for use. You would have to license it to use it, and from what I understand its not cheap. === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Image genration using jcchart & passing it to HTML client.
Hi, To generate a chart to client, you need to write a Servlet to generate the chart image (say, gif). 1. create a non visible Frame (i.e., call setVisible(false) or just don't call setVisible(true)) 2. add a chart to the frame and give the chart data to draw 3. get an ServletOutputStream 4. set the response content (say "image/gif" for gif). Optionally, you may want to tell the browser not to cache the image 5. get the raw image by calling the chart's snapshot() 6. use image encoder (like the one from Acme) to convert the raw image to other image format (like gif) 7. write the encoded image to the output stream You can now add an IMG tag to get the image from the Servlet.

Re: Image genration using jcchart & passing it to HTML client.
I build server-side .jpg images of charts, but instead of using the built-in image export code from my chart package, I use Sun's image export library 'cus it's faster. That's the com.sun.image.codec.* package, available on their site. _3 M === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
