Charts
I am trying to use the charting functionality, have looked at the
examples, and was wandering about showing a line in a category bar chart.
Is it possible to have a line (example an average value) in a bar chart,
if yes how do I do that.
If not can this be done in JFreeChart? (I understand this is not the
place to ask for this)
However, this leads me to a more architectural question:
Is all of the functionality from JFreeChart available in the Pivot chart
component, and is there a FAQ or guide (except the demo) about how to
use the jfree-provider.
Thanks in advance for your help.

OK, thanks anyway.

I suspect not, but I honestly don't remember. I wrote the charting API several years ago and haven't really looked at it since.

Greg,
thanks for your answers.
I've found on the JFreeChart website an example of a Dual Axis Chart:
is this possible through the provider?

Hello Bojan,
Sorry for the late answer but I was on a business trip and didn't have a
chance to work on that.
Anyway you could find in the attached zip file a sample application, the
interesting parts are
in biz.ixnay.pivot.charts.skin.jfree package, two new classes
GenericChartView and GenericChartViewSkin (that contains the JFreeChart) and
the modified provider JFreeChartProvider. The PivotChart is the Pivot
application in which the JFreeChart and the GenericChartView are set-up.
Cheers
Simon

If you use JFreeChart outside the context of the Pivot app (e.g. on a server) to generate static images, then you could do this.

I am completely ignorant on the subject, but is it not possible just to
provide a placeholder for a JFreeChart so that you don't need to include
it or the provider.
As you do with an image, you don't need a license to provide an
ImageView ... OK, maybe there will be no interaction on the elements
within the chart but the most common use case for the chart is to
display data and not the interaction.

We can't include JFreeChart or the provider in the platform due to license incompatibilities.

Hi,
interesting, could you share some of the code, as I would like to do the
same in Scala but don't exactly see where you're embedding the
JFreeChart, and why do you need the provider, could that not be just a
component of Pivot?
Thanks,
Bojan

Re: Charts

Hello,
I am also using JFreeChart in my Pivot application, and I needed to have
direct access to the JFreeChart inside the JFreeChartViewSkin. What I did is
to add a new ChartView class and the associated ChartViewSkin, I also had to
modified the JFreeChartProvider to take into account my new class.
And then in the ChartViewSkin a just added a "public void
setJFreeChart(JFreeChart chart)" method. So I am able in my application to
create the ChartView, put it in a Pivot container (Border, BoxPane or
whatever), create and set up the JFreeChart using any of the features of
JFreeChart and set it to the ChartViewSkin by using
chartView.getStyles.put("JFreeChart", chart).
Maybe not the cleanest way of doing this, must certainly less time consuming
than improving the wrapper to make all the JFreeChart features available.
Hope that help.
Cheers

Please disregard my last message (you were responding to the JFreeChart

So, how could markers be defined through Pivot if these are not in the
wrapper?

Thanks Philippe for your input, could you give me a hint how to define
