Actionscript Pie Chart?!?

Hey everyone,
I have a VBox to which I've added 3 individual PieCharts
through Actionscript. The PieCharts that i'm defining are being
added like this:
pieChartBox.addChild(pieChart) where pieChartBox is a VBox
and pieChart is a pieChart that I've styled and pushed a series
into.
In addition to this, the pieChart has an event listener like
this:
pieChart.addEventListener(ChartItemEvent.ITEM_CLICK,
regionChange);
I'm trying to implement the perWedgeExplodingRadius thing
where once the user clicks on a certain slice of the pie, that
slice is exploded from the chart. Right now, I'm able to identify
the set of possible values that are in the pieChart and the slice
that the user has selected.
Now. In order to get this effect to occur, I have to bind a
custom array that specifies the slice I want exploded to the series
that is defined in the pieChart. (via
series.perWedgeExplodingRadius = explodeArray) where explodeArray
is an array that indexes all the slices in my pieChart and
specifies the explodeRadius for the slice that I want.
The problem is, I don't know how to access the series of the
pieChart that I want in my listener function. I have everything
else implemented (everything that I think I need, anyway), and just
need this step to bind my code together.
Any Ideas?!?!
Thanks!!

You can't do this using the in built graph tool. The only method of graph items is duplicate an existing one. There is NO graph item creation. You can have a template file with a graph that uses data driven graphics but this means writing and importing .xml

Pie chart wedge itemRollOver

I need help with creating a custom pie chart class that will allow a function call on pie wedge rollOver.
Right now I can get a function call on rollover using itemRollOver using;
import mx.charts.events.ChartItemEvent;
-in the <mx:PieChart>;
itemRollOver="pieChart_itemRoll(event);"
-which calls this function
private function pieChart_itemRoll(evt:ChartItemEvent):void {
var psi:PieSeriesItem = evt.hitData.chartItem as PieSeriesItem;
trace(psi.item.target);
Please advise on how can I put this into a custom PieChart .as that extends PieChart?
Currently itemRollOver in my custom class throws an undefined property error.
Thanks.

OK, now I get it. So you would need to place your two PieCharts in a s:Group or mx:Canvas. On top of the pie charts, lay another s:Group on which you will do some drawing on its graphics:Graphics object.
In your case, you need to use dataToLocal() (will give you pixel coordinates in your chart) then localToGlobal() (convert to Application coordinates) then globalToLocal() (convert to the Top Group or Canvas coordinates you want to draw in) :
Using the dataToLocal() method
The dataToLocal() method converts a set of values to x and y coordinates on the screen. The values you give the method are in the "data space" of the chart; this method converts these values to coordinates. The data space is the collection of all possible combinations of data values that a chart can represent.
The number and meaning of arguments passed to the dataToLocal() method depend on the chart type. For CartesianChart controls, such as the BarChart and ColumnChart controls, the first value is used to map along the x axis, and the second value is used to map along the y axis.
For PolarChart controls, such as the PieChart control, the first value maps to the angle around the center of the chart, and the second value maps to the distance from the center of the chart along the radius.
The coordinates returned are based on 0,0 being the upper-left corner of the chart. For a ColumnChart control, for example, the height of the column is inversely related to the x coordinate that is returned.

Pie chart highlight selected wedge.

I am trying to highlight the current clicked wedge in a pie
chart by changing the property "outerRadius" of the item
(PieSeriesItem). But it has no effect... My idea is to expand the
wedge a bit above the others. Is there any other method? Where
should I go in the doc to find this?

Reporting Services in 2005 Secondary Pie Chart?

Hi,
In 2008 and 20012, secondary pie charts with a percentage threshold from a main pie chart can be easily created. Is it possible to do in 2005?
*CustomAttributes
Thanks.

Hi Robb,
It seems that you are using Dundas Chart Control for SQL Server 2008 R2 Reporting Services not the Dundas Chart Control 2005 that Microsoft has purchased.
Microsoft purchased the license to use Dundas Chart Control 2005 in Reporting Services 2008 and above. Therefore the supported upgrade is from Reporting Services 2005 Dundas Charts to SSRS 2008 (R2) and SSRS 2012 Charts.
If you are using a particular component released by Dundas for SSRS 2008 R2, you won’t be able to upgrade Reporting Services 2008 R2 Reports with Dundas Charts to Reporting Services 2012 Charts.
To confirm this, please check the details of this assembly “DundasRSChart.dll” located under the /Report Server/bin directory.
If the Product Name is “Dundas Chart for Reporting Services 2008 R2”, it indicates that this is a new version of Dundas Chart for SSRS 2008 R2 (i.e. a third party control). If the Product Name is “Microsoft SQL Server”, it indicates that this is the version
that Microsoft has purchased.
In this condition, you have to migrate the DundasRSChart.dll to the SSRS 2012 instance and reference it as the custom assembly in the reports. Please make sure to rename the DLL file so that it won’t replace the native DundasRSChart.dll installed by SQL
Server 2012.
For more information about referencing custom assembly in a report, please see:

Need help to make a Pie Chart

I am trying to draw a pie chart for the Uptime Report.
I have the Following table definition.
create table downtime_detail ( env_code number, down_start date, down_end date );
insert into downtime_detail values (1,to_date('26-JAN-2008 02:00:00','DD-MON-YYYY HH24:MI:SS'),to_date('26-JAN-2008 03:00:00','DD-MON-YYYY HH24:MI:SS') );
insert into downtime_detail values (2,to_date('26-JAN-2008 02:00:00','DD-MON-YYYY HH24:MI:SS'),to_date('26-JAN-2008 03:00:00','DD-MON-YYYY HH24:MI:SS') );
insert into downtime_detail values (2,to_date('01-FEB-2008 02:00:00','DD-MON-YYYY HH24:MI:SS'),to_date('03-FEB-2008 03:00:00','DD-MON-YYYY HH24:MI:SS') );
insert into downtime_detail values (2,to_date('15-FEB-2008 02:00:00','DD-MON-YYYY HH24:MI:SS'),to_date('15-FEB-2008 03:00:00','DD-MON-YYYY HH24:MI:SS') );
insert into downtime_detail values (2,to_date('26-FEB-2008 02:00:00','DD-MON-YYYY HH24:MI:SS'),to_date('28-FEB-2008 03:00:00','DD-MON-YYYY HH24:MI:SS') );
Now the Below Query returns me the values val1 and val2 on the basis of which I need to draw a Pie Chart.
==========================================================
select round((DOWN/TOTAL)*100,2) val1 , round(100-((DOWN/TOTAL)*100),2) val2
from
(select sum((DOWN_END - DOWN_START)*24) DOWN from DOWNTIME_DETAIL where ENV_CODE=2 ) a ,
(select ((sysdate - to_date('01-JAN-2008','DD-MON-YYYY')) * 24) TOTAL from dual ) b
VAL1 VAL2
3.64 96.36
==========================================================
Can someone help me try do this ?
Actually I tried but I couldnt put my custom query to get this Pie chart. Or if there is any other better approach please let me know.

nikhilskamik,
I believe all that you are missing in your sql is a NULL. Below is the help text for creating a Flash pie chart.
Specify the SQL query that will populate your chart, for example:
select null, ename, sal
from emp
Alternatively you can write a PL/SQL function return a SQL query, for example:
begin
return 'select null, ename, sal from emp';
end;
Your query should then read:
select null,round((DOWN/TOTAL)*100,2) val1 , round(100-((DOWN/TOTAL)*100),2) val2
from
(select sum((DOWN_END - DOWN_START)*24) DOWN from DOWNTIME_DETAIL where ENV_CODE=2 ) a ,
(select ((sysdate - to_date('01-JAN-2008','DD-MON-YYYY')) * 24) TOTAL from dual ) b

No data in Active sessions pie-chart and availability is 0%

Hi All,
Does anyone know why my Enterprise Manager cosole in Oracle 10g installed on windows xp professional is not showing any data? Availabilty is always 0% for the instance ORCL and the active sessions pie-chart is always showing 0.01 since May 17,2005.
Can anyone tell me how to configure EM so that instance ORCL and the active sessions start showing data again?
Thanks

Hi,
Kindly activate the data request. Post that, Under "request available for reporting" a symbol will appear which means that the data has been moved to Active table and is available for reporting at further levels.
And you can then check for contents in the active table of the DSo, you should get the records.
Change log: Contains the change history for the delta update from the DataStore object into other data targets, such as DataStore objects or InfoCubes. It makes sense in case of delta uploads.

ActiveX and pie chart problem

I am trying to create a bar of pie chart in Excel 2003. I am able to insert my data and create the chart, but I need to set the "SplitValue" to 6. I was able to find the property for doing this but I get an error when I run the vi (see attached). Any thoughts?
Solved!

I think your problem is that you don't have "Index" wired for the ChartGroups property. Thus, it may be returning a collection of chart groups, but you are typecasting it to a single chart group.

SSRS Report Builder 3.0 - Pie Chart

Hi,
I have Pie chart that displays Number of items by Country,
My data set is pulling the correct values.
The 3D effect is true for the pie chart and the Series Labels are set to diplay out of the Slice.
I used the collected style to be SingleSlice and not using percentages but just the values less than or = 5 to be collected to other countries slice.
for labels format I am using a column value from the query where I Concatenate the Value and Name of the country as string as I am not showing the legend on the chart for more space
All the values are showing up right except for one value for one slice which is added extra numbers at the beginning of the number part of the string.
For Example , if for USA there are 320 items it should should show up as USA - 320 as that is the value that the query bring and I double checked that. But that value dipslays USA - 12320 for some reason and this is happening only with one
label.
I might be missing somethign silly but if someone can save my time and help me it would be appreciated.
Please let me know if you have any questions.
Thanks,
Chaitanya

Hi Chaitanya,
Sorry for the delay.
I am unable to reproduce the issue in my test environment. The issue seems rather odd. Here, I suggest that you create a new report and design the Pie Chart from scratch, and then check the issue again.
If the issue persists, please post the expression of the label data as well as the CustomAttributes settings of the target series of the Pie Chart.

I have no idea how to set up a pie chart for tracking spending with categories

This is what I want to do to help me track my credit card spending.
I want to make a Numbers sheet where i can jot down how much money i spent on a item, and what category that item would go with (example, food, electronics, gas, so on).
and then i want to have a pie chart that will show much how much money i'm spending in each category and how much of a percentage of the total each category takes up of the whole.
I have no idea how to set this up in a sheet. I tried typing it in a few times and every time i go to make a pie chart, it never shows me any of the results i want to see.
can someone please help me set up a sheet to be able to get this information to display correctly in a pie chart?

Brad,
Create a table with the categories and the data (for now you can make up the data):
Now add a chart from the Charts menu in the toolbar:
Now click the "Add Chart Data" button just below the chart.
Now select data (from column B) in the table. Last trick is to click the menu at the bottom-left corner of the window and change the selection to "Plot rows as series" :
Now add formulas to the table to properly summarize the data from your data entry table using the sumif() function.

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.
