There is an action to click a legend element and highlight the bar/slice
but not the other way. It works is SVG, but SWT has a bug in it currently.

How do I link to a table from a slice of a pie chart?
My project manager is after me to add a feature to a pie chart built on one of my tables. The code that selects from the table for the pie chart is this:
select 'http://apexdevapp1.ci.raleigh.nc.us:7777',activity_type,count(ID) total FROM eba_ver2_cust_activity
where ACTIVITY_DATE BETWEEN NVL(TRIM(:P23_START_DATE), '01-JAN-2001') AND NVL(TRIM(:P23_END_DATE),
'31-DEC-2099')
group by activity_type,'http://apexdevapp1.ci.raleigh.nc.us:7777';
She wants to be able to click on a slice of the pie ("activity_type") and link to another page showing a report limited to that activity_type, selected from the same table. I know how to link from one interactive report to another, but I don't know how to do it from a slice of a pie chart. Does anybody know how?
I'd appreciate some guidance on this.

Have you compared that link with any of your apex application links in the browser? ;) :)

Pie Chart: How to capture data pertianing to the section whereUser clicked
In the UI there is a 1) Pie chart and a 2) table with search fields below the pie chart both displaying related information.
we have a requirement to allow the user to click on various sections of the pie chart lets say it has two sections 1) one showing number of people with insurance as 75% and 2) another people without insurance as 25%. when the user clicks on the area representing 75% then the search fields related to the table should be automatically populated with the data related to that region of the pie chart (75%) lets say if there is drop down that allows the user to search for people "with" and "without" insurance then it should be set to "with insurance" since the user had clicked the area in the pie chart that pertains to percentage of people with insurance. basically, looking for some examples that would help us find out how to implement this feature since new to ADF?Use clickListener in Pie Chart.
For details, check the documentation:

Histogram works, Pie Chart doesn't :(
I have a simple form, which has 1 block, a block level "when-new-block-instance" trigger and 2 bean_area under the block (beans don't have any trigger code). This simple form is called from within another form when a button is pressed. The histogram (bar chart) works, but the simple pie chart doesn't work (only displays a single circle - not the slices on the pie). The related trigger code is below. Can anybody see what is wrong with the pie chart code ?
Appreciated.

This uses the FormsGraph.jar file implementation as you can see. I know Frank Nimphius is the only expert when it comes to FormsGraph.jar at Oracle, but currently he is on vacation - so no official support to an unofficial (unsupported) charting implementation - but I thought there might be others who have done this before.
Can someone who implemented a pie chart share his/her code here - a simple pie chart, nothing fancy (like the one that comes with the graph90.fmb file, which I followed but did not figure out why my implementation is not working). Something with the vData string or number of vData strings requirement? no explanation in the FormsGraph.jar doc and I am not a java programmer to figure it out from the java source code. I am looking for a simple trigger code for the pie chart - not like "look at the forms90.fmb that comes with the demo package" kinda answer.
Thanx

I have develop a pie chart for Category Sales. If i click on one of the pie (Category) it should open a tabular report where it shows the sale of products in that category. How can i implement this in OBIEE dashboard?
Hi,
For your senario you can use Master Detail event feture to implement your solutions.
Master-detail linking of views allows you to establish a relationship between two or more views such that one view, called the master view, will drive data changes in one or more other views, called detail views.
More detail refer below linke;
http://gerardnico.com/wiki/dat/obiee/master_detail
Mark Helpful/Correct as applicable.

Top 10 Pie Chart in Webi 3.1 with "Others"
Hi,
I need to implement a Pie Chart in Web Intelligence 3.1., which must show the sales values only for the Top 10 countries with the highest number of sales.
However there is an extra requirement: I must include the option "Others" including the other countries (from 11th to the last).
I've been searching but I have not found any solution. Does anyone know the way to achieve this requirement? Using a Pie Chart is mandatory.
Thank you in advance!!Hi,
you may refer to the following links:

Pdf generated through API's does not display pie chart
I'm using BIP 10.1.3.4, running on Oracle Linux 5 connecting to a 11g database.
I developed an RTF using the word template builder and included a pie chart. Previewing from within Word works fine, running the report directly from BIP works fine. I then used the API's to generate the pdf programmatically to have more control.
I use RTFProcessor to convert my RTF into a XSL, DataProcessor to generate the xml data and FOProcessor to generate the final PDF. This works fine running from local JDeveloper, connecting through to the remote database.
I've now loaded the java class with the API's into the database, and as per http://download.oracle.com/docs/cd/E12844_01/doc/bip.1013/e12188/T421739T517850.htm#T520954, loaded up the following jar's
xdocore.jar - the core BI Publisher library
aolj.jar - although this is an Oracle E-Business Suite library, it is required for standalone implementations as well
i18nAPI_v3.jar - the i18n library used for localization functions
xdoparser.jar - the scalable XML parser and XSLT 2.0 engine
xmlparserv2-904.jar - the main XML parser/XSLT engine
bipres.jar - a charting library
bicmn.jar - a charting library
jewt4.jar - a charting support library
share.jar - a charting support library
collections.jar - you only need this if you are working with the delivery APIs or bursting engine.
The report works fine, all data tabels are shown but the pie chart is missing. I originally got the jar files from the TemplateBuilder/jlib directory. I also tried using the jar files from the BIP/xmlpserver\WEB-INF\lib directory as well. Problem remains - everything works fine except for the lack of the pie chart !
Any help would be greatly appreciated :)
Cheers,
Brentbump .... anyone had similar problems ?

How to show top 20 values in a Pie Chart
Hi
We have a requirement to develop a Pie chart for top 20 Order value locations.but i am not able to plug in top 20 logic in a pie chart.This functionality (TOP N) is avilable in bar chart , but it is not avilable in Pie chart. Could some help me to implement this logic in a Pie chart.
Your help in this regard is highly appreciated.
Thanks
LajNot sure what you are saying here. Obviously you have to have a place to place the distinct values, whether in another column or in the same column. That's not really a drawback, just a fact of life.
I'm curious about what you mean by "multiple columns to dynamically select some records with specific criteria from different columns." If you can give a specific example of what you are trying to do, I there may be a solution. Are you trying to do something like Excel's filtering on multiple columns?
If you are you can click the disclosure triangle by the column letter to get a dropdown like this:
Similar to Excel.

I cannot get my pie chart to show in my JPanel. I am not sure why that is or how to get it to display. Everything compiles fine...I feel like an idiot. Anyway, could you look at this and let me know what I could be doing wrong. My piechart starts on line 302.

Pie chart in combintion with a Slider control in Dashboards 4.0
Hi,
Following the my requirement for creating a dashboard.
1) i have to display employee count for different regions in a pie char for a particular month.
2) This month needs to be selected from a slider control(Horizontal).
3) The slider control needs to show Month and year (MON-YYYY format) for the last 13 months.6 months above the slider and 7 months below the slider.
4) So when a user selects a particular month by dragging to the particular month in slider, then the pie chart should display employee count for the selected month.
5) And Also the slider control by default should show last month employee count in pie chart when the dashboard is opened every time.
So Any body knows how to implement this requirement please send me the solution in a step by step approch.
Thanks in Advance,
Regards,
Nanda Kishore.Hi,
Set up your data like this
For the months we just use 0 for the selected month and we mark our min & max.
(I just took a few months, just as test, in real, you have to have all your months, off course)
Link the slider component, data to B2, min to B3 and max to B7
Create combobox, link labels to cell B3:B7
setup of data insertion, see screenshot below. (destination: j4:J7)
for behaviour column do as follows...
Your pie chart component
results in
now you have to put some makup on your dashboard, (hide the combobox - hide the values -6,0and 7), create some textcomponents to show the correct months (create a key row (-6 >0>7) and a month-text row), you can use vlookup or via a combobox to fetch the correct month-text
Have fun with it -
Insert Pie Chart to Excel Using OpenXml
I managed to implement the code(I got from MSDN) to create a bar graph in excel, I am however facing challenges in creating a piechart, I had thought that I can manipulate the code a little bit and produce a pie chart-but I have spent nights and
nights still can't find my way to create a pie chart. I need help on this, I would appreciate if you can help me through this.
F.ShumbaHi F.Shuba,
From the description, you want to create a piechart using Open XML.
A recommend way is that create a pie chart manually and use Open XML SDK 2.5 Productivity Tool to open this workbook. Then you can get the code for creaing the chart for reference.
If you still have issue, please feel free to let me know.

Hi!
In My application i want to create few bar and pie chart.
If is there any code for generating bar and pie chart,
pl send me.
If third party software is available tell me the details of it.Sure, this functionality would be nice to have right
out of the box, but when you think about it: should
Sun be distributing a reporting SDK and promoting bad
practices anyhow? Implementing your reporting in
disparate and distributed manners is just plain messy
and definitely translates to a bad practice. Turning
to a centralized reporting mechanism, driven by a
reporting server that can handle the needs for 80% of
your requirements is a helluva lot more thoughtful and
mindful than implementing separate mini reporting
engines encapsulated within each and every application
that you deploy.Elegantly stated! On a practical point, my company built an Enterprised based reporting solution on top of Java technology within the windows environment (please be kind). Specifically we used Java, ASP and Javascript (no VBScript), and delivered the information using the Microsoft IE 4 and 5.
However, since Microsoft chose to elminate Java from it's current browser (IE6), we have to throw two years of coding away. We are now in the process of moving backward (technically speaking) to a desktop reporting model using Java (no browser technology) that accesses an Enterprise database, or embedded Java database. None of our customers are using Netscape, so that was never an option. Microsoft's and Sun's inablity to cooperate almost decimated our company's product line (and it still may).
So I agree with you that an Enterprise server based reporting solution is the best architecture, and yet here I am running away from it after a two year struggle with competing standards. Sometimes the best solution loses for reasons that are simply not technical in nature. -
In a ADG is it possible to have a pie chart in a summary row?
In a ADG is it possible to have a pie chart in a summary row?
The segments would be worked out from a funtion applied to the data
in that grouping.
Thanks :)The JTable is a tabular component. So it will always have enough columns to display the maximum row length. you don't have to pur a value in every cell.
There are methods in JTable to remove horizontal and vertical lines and you could implement a renderer to make empty cells look like the background.
