not right now. This functionality will be in the 0.7 release, but it is not fully implemented just yet. A guy donated code to do this, which i attached. You should be able to lay this over the 0.6 source and have it work. Do you think i should post this on the website, under a user submission section? --- Mihael Knezevic <m.k...@po...> wrote: > hi, > > i'm new to this list and don't know if this has been discussed before. > > is it possible to place the value of each bar on top of it? > > thanx in advance. > > mk > > > ------------------------------------------------------- > This SF.NET email is sponsored by: > SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! > http://www.vasoftware.com > _______________________________________________ > jCharts-users mailing list > jCh...@li... > https://lists.sourceforge.net/lists/listinfo/jcharts-users ===== An easy read on your Digital Rights Disappearing [http://newsforge.com/newsforge/02/10/21/1449250.shtml?tid=19] Broadcast Protection Discussion Group [http://bpdg.blogs.eff.org/] Senator Hollings receives a pathetically piffling $278,534 to his coffers from the TV, movies and music businesses [http://www.theinquirer.net/?article=4689] __________________________________________________ Do you Yahoo!?

when you use the HttpSession, the server keeps track of you via a cookie on your browser. If you do not have cookies enabled the HttpSession will not work correctly.

sounds like you are not using different keys in the httpsession. If you are putting two Chart instances into the HttpSession you need to store them under different keys and to get them using those different keys. I have no idea why you other approach does not work, but it does not sound like you need to write to a file, as it is a huge performance liability. --- Srini <sr...@le...> wrote: > I have both the codes working.

this is a design bug with the encoders that was just caught recently. The problem is the encode
method is overloaded so the compiler does a type check on each signature to find the correct
method to invoke. So there is a dependency on the HttpServletResponse Object.
This should only be a compile time dependency and not a runntime dependency.
This has been fixed in the 0.7 release by changing the name of the encode method which takes the
HttpServletResponse Object.
You could alter the source of the JPEGEncoder13 and comment out that method or change its name as
a short term fix. I guess i could create a patch for this one thing if you really need it.
Sorry for the inconvenience.

did you look at the users guide? There is a whole section on how to create an image map for your charts. the demo uses three two Servlets and a jsp. One servlet creates the chart and calls the methods to encode for an image map. This stores the chart in the HttpSession so a generic Chart Servlet can later pull it out of the session and stream it back as a png. All chart types extend the Chart Object which is what the encode methods require so a single servlet can encode any chart type. the response from the first servlet sends the image map data back in the HttpServletRequest to the jsp. The jsp has an <img> element which calls the chart servlet to get the image from the session and stream it back. --- Srini <sr...@le...> wrote: > Assuming I have a servlet which creates a jpg file, How may servlets and jsp > file I have to write to make it work with imagemap. > > What are the functions of those servlets and jsp? > What modifications I have to make my servlet? > > Thanks in advance > > Since I am not able to figure about these things from your demo programs, I > am sending this email > ===== An easy read on your Digital Rights Disappearing [http://newsforge.com/newsforge/02/10/21/1449250.shtml?tid=19] __________________________________________________ Do you Yahoo!?

if you are doing your reports in html i see no reason why you cant use two requests to the server; there is no way to return an image and text in the same request; even in your approach, there is a request to the servlet to generate stuff, then a request to get the image. You dont have to loop the image map coordinates in a jsp, you could do that in a servlet. Also, why not embed the chart code in your report page? even if you want to include a jsp which contains the chart and image-mep, you should be able to use the same jsp to create all your charts just like i did in that demo code. You could use the HttpSession to map the imagemap name to the imagemap --- Srini <sr...@le...> wrote: > Hello!! > > I did not really understand the overall organization of the code in your > clientside view demo.

hey Srini
Is there a reason you want to write the image to a file? This is will be a liability when you try
to scale your app. Why do you want a single request to the server and not use two requests?
Also, looking at your code, i dont think it is thread-safe. There is a possibility for the
counter on the file name to not get incremented and have another thread use the same counter. you
would have to synchronize the creation of the file name and increment of the counter. This will
be a performance liability too.
just my two cents.

Yes that is true, i want my method to return the Chart object not the output
stream ( so that chart generation can be a separate method and streaming
it OR saving it can be done sepearately based on some conditions which should
be outside the chart generation methid.)<br>
How can i do this ?<br>
<br>
(p.s - I am not writing a applet.)<br>
<br>
Thanks for your inputs.<br>

However you get or create an OutputStream is totally independent of jCharts. It sounds like you
want your method to return the Chart Object not the OutputStream.
Are you trying to create an applet? There is example code for this in the org.jcharts.test
package.

Thanks for the info... in the forum.
but that is not what i am looking for.(Was not able to post
a reply - it says duplicate message- so sending this mail)
I want something like this (return some kind of
OutputStream, that can either be sent to the browser OR
saved to a file). How can i do something similar to this...
public OutputStream getChart()
{
.....//some code here....etc.
OutputStream os ;
JPEGEncoder13.encode( axisChart, 1.0f, os);//This statement
should not save chart to the file OR send output to browser,
I am interested in getting the OutputStream object from this
method.
return os;
}

I am not sure what you are asking.
The ChartServlet used in the demo code was just for that demo code and not intended to be part of
the core jcharts API. You certainly can copy it from the demo and modify it to do whatever you
need.
Each chart on a page needs a separate request to the Server. so you would need two or more <img>
tags.
Yes, the encode(...) methods return void. Would you prefer them to return something?

In UserGuide 0.2 all examples use dataSeries.addIAxisChartDataSet(axisChartDataSet); but it's marked as deprecated API, is there any direct replacement for this? regards marcin |

sorry but this is how the jCharts license works. You dont have to include the source of jcharts or open the source of your code since you are using jcharts in your product. Alls the license requires really is that you include a copy of the jcharts license with your documentation and include a footnote somewhere in your documentation giving credit to the jcharts project. ---nathaniel --- Brian Maguire <bma...@va...> wrote: > Thanks for the reply.
