Hello,
=20
I have a combo box containing:
=20
- stacked bars
- lines
=20
The lines represent the total for each of the items contained in the
stacked bar
The X axis contains dates
=20
ex: the stacked bar contains X, Y, Z at dates d1, d2, d3.
The lines describes the sum of:
- X at d1, d2, d3
- Y at d1, d2, d3
- Z at d1, d2, d3
=20
So, the legends for the stacked bars and for the lines are the same.
=20
My problems is as I had two datasets, with the same legend, the legend
appears twice.
=20
Is there a way to avoid that?
=20
Many thanks
=20
Gilles=20

Hi all !. I have some questions. First, I've seen some 3D Pie Charts, how can I get one ? Is there some examples to get one ? Second, I need to create a chart with interval scale on "y axis", for example '15:12' ( 15 hours and 12 minutes ) , ... , '08:15' ... '00:10' . Is there a way to do that ?

sure, you can set the a-axis labels to be vertical. call the following method on the AxisProperties Object: axisProperties.setXAxisLabelsAreVertical( true ); You can control the pixel dimensions of the chart image via arguments to the Constructor. --- "Ducret, Gilles (MSCI)" <Gil...@ms...> wrote: > Hello, > > First of all I would like to say how impressed I am.

Sure. I would recommend using a Servlet to generate your chart as jsps are not meant, according to the JSP specification, to create binary data. When you use a Servlet, simply have the src attribute of an img tag reference your Servlet. such as: <img src="somePath/myLineChart"/> --- "Ducret, Gilles (MSCI)" <Gil...@ms...> wrote: > Hello, > > I am a new user of jchart. > > At the moment I am generating a single graph in a jsp page, using > the encoder. > > It seems that I cannot happend anything else in this page, only the > graph. > > Could you please tell me how I can: add my content plus the graph, > > and add several graphs in the same web page. > > Many thanks > > Gilles > -------------------------------------------------------- > > NOTICE: If received in error, please destroy and notify sender.

The complete source is not there, but some of it is; most of the samples use a Randomly generated Paint implementation. Take a look at the TestDataGenerator.getRandomPaint() method. You can do transparency by using: new Color( r, g, b, a ), where a = alpha Take a look at the javadocs for java.awt.Color for more info on that Constructor. --- "Campano, Troy" <Tro...@Li...> wrote: > Is there source code available for the samples at > http://jcharts.krysalis.org/samples/index.html ? > > I'm trying to get some nice looking colors and find out how the > transparency of colors is being done. > > > Thank you! > > ~ Troy Campano ~ > __________________________________ Do you Yahoo!?

Hi,
I did a Radar legend implementation myself (sent it to Nataniel off
list) :
"
I've had a look at the code, and made a legend implementation for the
Radar chart. The doesn't take the axis labels into consideration, so the
labels and legend may be on top of each other if the legend is LEFT or
RIGHT (this does not apply to TOP or BOTTOM).
Changes:=20
Legend.java: I had to do som additions to avoid classcast exceptions:
-calculateDrawingValues() : added else if (iData instanceof
IRadarChartDataSet ) {...} -Added method : private void processData(
IRadarChartDataSet iRadarChartDataSet ) {...} -Added method: private
void processLegendLabels( IRadarChartDataSet iRadarChartDataSet ) {...}
RadarChart.java:
-Added legend redering to : protected void renderChart() { ... }
I've attached the two files if you wan't to update the CVS repository.
"
I'm not able to compare my code and your code until monday, but I think
this is pretty much what you've done too...
Thanks for looking into problem!

Emne: [jCharts-users] radar chart legend patch
Hi Folks, Hi Nathaniel,
at least I got the problem with scaling the radar chart fixed as well.
Anyways this has more the character of a "hack" then a clean patch.
Sorry I'm to much in rush, but i wish that other can participate.
Here is a patch that anable legends in radar charts.
Just update a cvs jchart checkoput (e.g. apply patch in eclipse) and=20
rebuild your jchart.
This patch has following known problems:
1.) if your legend is much to big the may be the labels of your radar=20
chart is cutted on the side. (sorry dont know to fix)
2.) my ide had reformt some code that is not involvedin the radar legend
chart issue. Sorry was a mistake. (That why so much is marked as deleted
and added in the patch file)
Hope that helps you Mathias and Jarle.
Cheers
Stefan

What happens if you increase the width of the image? It sounds like it
might just be because the
label length is too wide to display for that image width.

Part of it. The Scale Calculators determines the value of each each segment on an axis. So yes,
you would want to create a new implementation of one for a Logarithmic scale. But then you also
would have to implement a new YAxis Object or enhance the existing one to plot the uneven amounts
on the y-axis.
I could help you with this part of it, if you need it; it would be a great addition to the
library.

Hi
I have looked through the JavaDocs and found the class ScaleCalculator (in the
org.jcharts.axischart.axis.scale package). I have not tried it yet (due to lack
of time), but will it be possible to implement a specialized version of this
class and use it to compute a logarithmic scale for me?
Has anyone done this?
Thanks
regards
Bent Are Melsom

Logarithmic scales are not yet possible. You can set the min and increment of the scale, but this
will not give you a logarithmic scale as I understand it. Take a look at the javadocs for the
AxisProperties Constructor.

Hi
Thanks that worked out just fine. time for another question;)
Have anybody used a logarithmic scale on one of the axis? I hava a need
for this. Is there some way in which I can set the values of the markings
on an axis? This way I can compute the scala and set the values to the
axis.
regards
Bent Are Melsom
