[jCharts-users] Pie Chart

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

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=20

Re: [jCharts-users] 3D pie chart in a JSP

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

JSP's are not a good way to generate charts.   You should use a Servlet.  Sounds like your problem
is that there is white space somewhere in your jsp.  Any 'white spaces', will be translated into
something like: 'out.write( " " );' by the jsp compiler.  These can be a major pain in the ass to
track down.

JSP's, according to the Servlet Specification are not meant to output binary data; they should
only be used to output text.

[jCharts-users] RE: [jCharts-developers] 3D pie chart in a JSP

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

I get a blank image , similar to one when you have the wrong image
path......
I have checked the code a few times but cant seem to figure out why....
Also I am using a BEA weblogic 8 portal server, don't think that should
make any difference though.....

you do not want to include the output of the Servlet in your page as you will get the encoded

Re: [jCharts-users] Legend icons / Labels

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

Value labels are not currently supported in the stacked bar charts; only the bar anc clustered
bars.

From the User Guide:
"It is now possible to display value labels on your Bar and Clustered Bar charts, but not Stacked
Bar Charts"


Take a look at the org.jCharts.Legend Class.  There are several calculations which would need to
be updated to deal with user defined icon sizes. These are all due to the sizing and positioning
of the Legend.

[jCharts-users] Legend icons / Labels

[<doo...@gm...>]

Hello!

I've been using Jcharts for some time now and I think it's pretty easy to
use and creates nice output. Recently I've run into a couple of problems:

1) I have created a stacked Barchart but cannot get JCharts to display the
labels. Specifically I'd like to place the labels within the bars - is that
possible? 
Here's my code:

ValueLabelRenderer valueLabelRenderer = new
ValueLabelRenderer(false,true,true, -1 );
valueLabelRenderer.setValueLabelPosition( ValueLabelPosition.ON_TOP );
valueLabelRenderer.useVerticalLabels( false );
stackedBarChartProperties.addPostRenderEventListener( valueLabelRenderer );



2) Is there a way to change the size of legend icons - these little boxes
which are positioned right in front of the label? If not, could anyone
please give me a hint as to where to find it in the source?

Thanks in advance,

Katrin

Nathan,

Those of use who are using IBM's Websphere will still be at jdk 1.3.x =
for awhile.  I haven't heard when 1.4 will be integrated into Websphere.

Thanks,

[jCharts-users] krysalis-jcharts 1.0.0 alpha 1

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

krysalis-jcharts 1.0.0 alpha 1 is now available for download.

You will have to adjust the package naming of the classes which are now: org.krysalis.jcharts.*

Remember, this is an Alpha release, meaning things are still going to be added and possible
changed before the 'final' 1.0.0.  While the code passes all the visual tests, there may be some
bugs lingering about. Don't let this scare you though...Have a go at her! 

For a list of the changes: http://jcharts.krysalis.org/changes.html

[jCharts-users] java.io.NotSerializableException: org.jCharts.properties.util.ChartFont

[Teodor D. <te...@us...>]

Hello,

In an attempt to serialize a org.jCharts.axisChart.AxisChart object
I received this exception:

 java.io.NotSerializableException: org.jCharts.properties.util.ChartFont

I need to serialize charts (the *org.jCharts.Chart* class implements 
java.io.Serializable)
in order to improve the quality of charts in the JasperReports library.
If everything goes as planned, I'll provide you with a new improved
version of the JasperReports and jCharts integration sample.

Thank you,
Teodor

Re: [jCharts-users] Problem in Image map generation

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

i checked in some changes for this under the krysalis-jcharts module.  I still need to do some
testing for user defined scales that do not show zero on the y-axis.

Re: [jCharts-users] Problem in Image map generation

[Travis R. <tra...@ec...>]

Probably easiest if you do it, but I looked and I think it's here in 
verticalPlot():

if( rectangle.height != 0 )
                {
                    g2d.fill( rectangle );

                    if( barChartProperties.getShowOutlinesFlag() )
                    {
                        barChartProperties.getBarOutlineStroke().draw( 
g2d, rectangle );
                        g2d.setPaint( iAxisChartDataSet.getPaint( 0 ) );
                    }

                    //---if we are generating an ImageMap, store the 
image coordinates
                    if( axisChart.getGenerateImageMapFlag() )
                    {
                        String label;
                        if( axisChart.getXAxis().getAxisLabelsGroup() != 
null )
                        {
                            label = 
axisChart.getXAxis().getAxisLabelsGroup().getTextTag( i ).getText();
                        }
                        else
                        {
                            label = null;
                        }

                       * axisChart.getImageMap().addImageMapArea( new 
RectMapArea( rectangle,
                                                                        
                             iAxisChartDataSet.getValue( 0, i ),
                                                                        
                             label,
                                                                        
                             iAxisChartDataSet.getLegendLabel( 0 ) ) );*
                    }
                }

Should move that addImageMapArea out of the:   if( rectangle.height != 0 
) { block so it adds regardless.

Re: [jCharts-users] Problem in Image map generation

[Travis R. <tra...@ec...>]

Well nothing, it's not really that it needs to be clicked on, but the 
iterator no longer matches the graph.  It would be nice to have it at 
least return something and you could check the imageMapArea.getValue or 
something to know whether to output that portion of the map html or some 
way at least to know that it skipped a column.
ex:

ImageMapArea imageMapArea= (ImageMapArea) iterator.next();
    if(imageMapArea.getValue() > 0){
	...  do the rest here
	imageMapArea.toHTML()....
   }


Maybe your idea of clicking on the x-axis is a perfect idea, then you don't even have to check and it would be backwards compatible.

what would you click on if there is nothing drawn? The axis?

[jCharts-users] Problem in Image map generation

[Travis R. <tra...@ec...>]

If a bar is 0 value, then it seems like no ImageMapArea is is returned 
for that bar.  This is problematic when the bars link to dynamic values 
for example:

 ImageMapArea imageMapArea= (ImageMapArea) iterator.next();
    html.append( "href=\"processList.jsf?status=" );
    html.append( matchingStatusCodes[mapCount] );
    html.append( "\"" );


Any ideas to get around that?

Re: [jCharts-users] Refresh_problem

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

I think you should override the "update( Graphics )" method so that it does not clear the
Components background when the window is resized.
