[Nick C. <ni...@ch...>]

Great to hear you using JCharts.  Please ask your question on the list 
(which I have CC) so that everyone can help, and benefit from the answers.

R,
Nick
ps.  I personally have no JChart experience.

Re: [jCharts-users] Encoding types

[Nathaniel G. A. <nat...@ya...>]

encodeJPEG13 is for legacy apps running on jdks up to and including 1.3
encodeJPEG uses the newer encoding methods in jdk 1.4+
encodeServlet is a helper which sets the mime type based on the encoding and encodes the image.


take a look at the documentation + source for more info...

[jCharts-users] Encoding types

[Fredrik L. <fl...@tr...>]

Hi,

I'm a bit confused about the different types of encodings.
What's the difference between encodeJPEG13 and the regular encodeJPEG
And what is the encodeServlet? what is the purpose of that one?

Thanks!

Fredrik

Hello,

I solve my probleme of date time plot. 

Now it is an another problem

My X axis have 7 days (for example)
But ma String[]legend labels have more....with 7*24 date string... 

I want to only have seven day in the legend of the X axis... Not 12 day and someday are write twice

I try something with
 DataAxisProperties dataAxisProperties= (DataAxisProperties) axisProperties.getXAxisProperties();

and after scale the axis...
but i have a exception

Is there anyone who have the same probleme with an Xaxis

Thanks 

PS : Jcharts have many possibility thanks to the develloper

Re: [jCharts-users] Serialization problem.

[Nathaniel G. A. <nat...@ya...>]

there are two things you could do:
1) alter the source to make the BasicStroke transient
2) change your code to create the chart on the client side.  I would recommend this as it adheres
to MVC.  You should only gather the data on the server and let the client do the rendering.

I will update the source so that the BasicStroke constants are transient.

[jCharts-users] Serialization problem.

[Greg J. <gr...@dc...>]

Hi,

I have a problem with serialization or maybe I have wrong understanding 
of where Chart object should be instantiated. I saw a post on 2004-05-31 
06:05 (Re: java.io.NotSerializableException: 
org.jCharts.properties.util.ChartFont) which solved some of my problems 
but I still can't make it to work. Here is what I am doing. I have a 
java client-server application which is using RMI for networking. So 
what I am doing is creating a PieChart2D object on a server side and 
then I am trying to send it over the network to a client. Then on a 
client side I am converting it to an image and displaying it. Issue is 
that when I make a request from client to server I get 
java.io.NotSerializableException: java.awt.BasicStroke error. I looked 
through the code and I see that PieChart2DProperties have been fixed to 
use ChartStroke which is now serializable instead of BasicStroke but for 
example LegendProperties still use BasicStroke. So my question, is that 
a bug or I should create my charts on a client side.

Thanks

Re: [jCharts-users] Explicitly setting Y-axis range

[Nathaniel G. A. <nat...@ya...>]

There is a method on the DataAxisProperties Object which you can control the range by specifying a
minimum and increment.  You need to also change the rounding value to include smaller numbers.

[jCharts-users] Explicitly setting Y-axis range

[Chris H. <hof...@cs...>]

I know this must be simple to do, but I haven't been able to come up 
with the proper incantation yet. I want to set an explicit range for the 
  y-axis of my bar chart, say from 0.0 to 1.5, regardless of the range 
of the data values (assuming all values are within that range).

Although my data points are all either zero or around 1.0, the only 
ranges I've been able to get jChart to produce are 0..4 and 0..1, the 
latter truncating any bars that are above 1.0.

Thanks,
Chris

Re: [jCharts-users] how to embed Jchart on a web page

[Nathaniel G. A. <nat...@ya...>]

you could use an applet to display a chart. Take a look at:
http://jcharts.krysalis.org/userGuide/exportingImages.html#Charts+In+Swing+Apps

Or you could use a Servlet. Take a look at the .war file that comes with the download.

[jCharts-users] how to embed Jchart on a web page

[Mir M. M. <mh...@ri...>]

Hi,

I just downloaded Jcharts and was wondering how can i display a web page 
with a bar chart. I am using Oracle Application Server and pl/sql. In 
past i had used some Java classes with <applet ..> tag to display 
charts. can i do the same with Jcharts, if yes how, sample code will be 
very helpful. Since i am not a Java person i am not sure how to use it.

any help is appreciated.

thanks
Mir

[Lora L. <Lor...@sa...>]

I am trying to get one of my charts into a pdf file.  I am able to do so =
with the JPEGEncoder.encode method and setting the output stream =
appropriately; however, I am unable to have anything else in the pdf.  I =
am wondering if the chart can be rendered in another way.  Specifically =
I would need something that returns an image instead of outputting the =
chart directly.  Has anyone ever had this problem?  Any help would be =
appreciated!

Thank you,

[jCharts-users] I've probem with jCharts on Solaris 8.

[Di G. P. <PD...@ap...>]

Hi,
 
I've an application that uses jCharts-0.7.5; it works correctly on
Tomcat4.1.30 with j2sdk1.4.2_05 on Windows and Linux .
I've deployed this application on a SUN Sparc 64 bit with Solaris 8, but
the application doesn't start because I receive an error in the init of
jCharts.
 
This is the error:

    }
 
Is there a way to resolve this problem in order to make jCharts work
properly under Solaris?
If you could supply me with some information I would be more than
thankful...;-)
 
Thank you in advance
 
Yours sincerely

[jCharts-users] Improving 3D pie charts

[<kar...@bt...>]

Hi there,
I am trying to create a 3D pie chart=20
I was wondering if I could=20
1. reduce the amount of space in and around the actual pie chart , there
Seems to be a lot of space around the pie chart itself.

2. Also sometimes the pie chart gets saved as a bmp only , any ideas why
that is ...


Thanks
Karan

Re: [jCharts-users] Percentages on pie chart

[Nathaniel G. A. <nat...@ya...>]

This is not in the codebase as of yet.  It might make it into 1.0.

As a ework around, you could set the values to be the percentages. For example if your data set
had 5,5,10 you could change that to be the percentage values of: 25,25,50

[Nathaniel G. A. <nat...@ya...>]

Singha,

If you are looking for the quickest response, do not email me or any of the project committers
directly; you should email the Users mail list.  I will not answer emails directed at me
personally in the future.  What if i am on vacation or unreachable for a period of time?

I am not sure I understand your problem.

RE: [jCharts-users] Pie Chart

[Nathan F. <nf...@Wo...>]

I have often though it might be useful for the case of long names to turn
the legend off, and make some spiffy html to hold your own legend, that
looks like it is in the chart.  This gives you all the control of css or
whatever tabley structure one could want for a legend.

Subject: [jCharts-users] Pie Chart



Hi , 
I had another query !!!! 
I am making a Pie chart via a servlet, and wanted to ask if its possible to
overlap the labels to the next line . 
The problem I am having is the Pie chart doesn't display all the labels as
they are quite wordy 
Eg a label could be "sfs004.solutions.vbc.com" 

Any ideas? 

Thanks
