Label on Bar Graph

Dear Champs ,
I am using one Function Module that is GRAPH_MATRIX_3D.
In this i am getting the data correct and object is working fine.
I want to label the graph by putting the value on the tower like ( 300 kg, 400 kg ).
Please help me out .
I will be highly thankful to you.
Thanks and Regards

Adding data labels to column graph

I work in the financial industry and I have to add data labels to all bars that appear in my ten year performance graphs (see http://fundinvestor.calamos.com/ClosedEndFunds/CEFund.aspx?name=CHI under the "Performance" tab as an example). Is there a script that can do this? I saw there's this technique that Adobe offers for column totals: http://livedocs.adobe.com/en_US/Illustrator/13.0/help.html?content=WS714a382cdf7d304e7e07d 0100196cbc5f-619e.html but that's not working. What am I doing wrong? Adding data labels to bars is ridiculously simple in Excel, why can't I find the way to do it easily in Illustrator?

http://help.adobe.com/en_US/Illustrator/14.0/WS714a382cdf7d304e7e07d0100196cbc5f-619ea.htm l
That should do the trick.

Using stored parameter from data control class with stacked bar-graph

Hi folks,
I'm relatively new to ADF & EJB so I want to apologise in advance if this question seems rudimentary to many of you.
Edit: I should have mentioned that I'm using JDeveloper 11.1.1.5
I'm having a hard time determining how to retrieve the value from a variable to be assigned to a property of the bar graph I'm trying to display on my JSF page.
I have tried to briefly summarise the logic below for reference.
I have a data control class (ActivityChart) that includes a method "getActivityDetail" returns a List of custom Objects (ActivityDTO) that are the underlying data for my bar graph.
public class ActivityChart {
    private Double axisScale;
    public ActivityChart() {
        super();
        axisScale = 0.0;
    public List<ActivityDTO> getActivityDetail(List<String> businessUnits) {
        List<ActivityDTO> returnNewList = new ArrayList<ActivityDTO>();
        List<TransactionDTO> dataList = new ArrayList<TransactionDTO>();
        TransactionSessionBean transBean = lookupTransactionSessionBean();
        if (businessUnits != null && !businessUnits.isEmpty()){
            dataList = transBean.getActivityData(SystemUtil.getCurrentUser(), businessUnits);
            returnNewList = processTransactions(dataList);
            axisScale = calcAxisScale(returnNewList);
        return returnNewList;
...The TransactionDTO object is basically a mirror of the entity object to store the fields from the queried db transactions.
The ActivityDTO object contains a String value (x-axis label) and 3 Double values for the values required for the bar graph.
What I'm trying to do is dynamically set the scale for the 2 y-axes (I'm using a dual-axis stacked bar graph) because the auto calculated values are not aligned.
Right now I've got the two relevant elements of the bar graph hard-coded with a specific axis value:
<dvt:y1Axis axisMaxAutoScaled="false" axisMaxValue="100.0"/>
<dvt:y2Axis axisMaxAutoScaled="false" axisMaxValue="100.0"/>.
The value I want to use for the Y-axis is calculated and stored in the "axisScale" variable in the above class.
Really at a loss of how to move forward from here.
Would very much appreciate any guidance/direction offered.
Thanks,
Karim

Looks like I may have found the answer!
I had to set up the variable in the bindings for the page and then reference the variable from the binding and add the property inputValue.
ie. value="#{bindings.axisScale.inputValue}"

Stacked bar graph requirement in OBIEE 11g

Hi,
I have stacked bar graph. I want to display units on the middle of each stack. I can display units, but by default these units are displayed on top of each stack. I checked properties of data markers, but I did not get any option to display data in the middle of stack.
I am using OBIEE 11g.
Is there any way to accomplish this?
Thanks.

We recently logged an Enhancement Request for the same with Oracle: Bug 15928667 : ENH DISPLAY DATA LABELS IN STACKED BAR CHART WITHIN THE BAR GRAPH ITSELF
There is no way out-of-box to do this as of right now.
Please assign points if helpful/correct.

Can't show data labels in pie graphs as decimal number if the crosstab data

I want to show my data labels in diagrams, as percent values, with three decimals.
It occurs (in version Oracle Business Intelligence Discoverer Plus 10g (10.1.2.55.26)) it is only possible if the data format of the crosstab data also shows data with decimals. If the data are in integer format, the graphs data labels can only be shown in integer as well.
Does anyone know how to fix the problem?
In version Oracle Business Intelligence Discoverer Plus 10g (10.1.2.48.18) we can have a crosstab showing integers and a pie graph showing labels of pie slices where the labels are in percent with three decimals. It seems it does not work in the newer version Oracle Business Intelligence Discoverer Plus 10g (10.1.2.55.26)
Thanks in advance

It seems I have another similar problem in version Oracle Business Intelligence Discoverer Plus 10g (10.1.2.55.26):
I have a Bar (Percent) graph based on a crosstab where the data is formatted as number with two decimals.
The labels in the graph shows as number (0,76 instead of 76% and 0,13 instead of 13%). I want them to be shown in percent format.
The Data Label format is set to “Number” with two decimals. I can change the Data Labels to Percent with two decimals and then it shows the data labels in the graph exactly as I want it. But after I have saved the workbook and then opened it again the changes has been “revoked” and is once again set to number with two decimals instead of percent.
thanks (again) in advance

Problem with Bar Graph

Hi Experts,
i am using obiee 11g and i build a report using bar graph view.
here problem is in horizontal axis some of my values are missing alternative values are only showing in.
Bars are showing but labels for that corresponding bars are not displaying .
pls help me

Increase the width of the graph something 1000 or so.

Stacked + adjacent bar graph

Can Discoverer do something like this:

ELOCATION_MERCATOR.WORLD_MAP errors for pie/bar graph theme below zoom 5

Hi,
I am trying to create a map using ADF DVT map component in my jspx page. I am using 'elocation_mercator.world_map'. I am creating a pie graph theme over the base world map. For some reason whenever I zoom below 5, i get following javascript error
[MVThemeBasedFOIControl.foiLoaded] MAPVIEWER-05523: Cannot process response from MapViewer server. (<?xml version="1.0" encoding="UTF-8" ?> <oms_error> MAPVIEWER-06009: Error processing an FOI request.
Root cause:FOIServlet:null</oms_error>)
The Pie graphs displays fine at or above zoom level 5. I tried the same thing using my local map viewer instance which has mvdemo.demo_map as the base map. The pie graph displays fine at all zoom levels using my local map. Can anybody tell me what may be the problem when I use the elocator world_map. I can't even look at the logs as it's a hosted service.

Here are the steps to reproduce the problem
1) Create a jspx page.
2) From the component palette on the right hand side, select ADF Data Visualizations and then click on Map in the Geographical Map section. This will open an ADF Map configuration window.
3) Create a new Map Configuration by providing an id and a URL connection. If you have not created a URL Connection to elocation service, create a new connection to "http://elocation.oracle.com/mapviewer" and select that connection.
4) You will see data source as ELOCATION_MERCATOR and Base map as WORLD_MAP selected. Enter startingY="38.648911" startingX="-98.349609" , select mapZoom="5" and Click on OK.
5) Now create an entity object and a view object based on the STATES table in the MVDEMO database and add it to an application module.
6) Refresh the application module data control. You should a new StatesView1 data control.
7) Drop it on the map and select Bar graph theme. This will open a Bar Graph theme configuration window for the Map.
8) In the Name select MAP_STATES_ABBRV. In the location column select STATE_ABRV.
9) In the Data Location Select Location as StateAbrv and Location Label as State.
10) Enter Series Attribute as Totpop and Label as Total Population. Enter series attribute as Female and Label as Female Population. Click OK.
11) Now Run this page.
12) The page runs fine displaying the Bar chart. Now zoom out. You will get error
'[MVThemeBasedFOIControl.foiLoaded] MAPVIEWER-05523: Cannot process response from MapViewer server. (<?xml version="1.0" encoding="UTF-8" ?> <oms_error> MAPVIEWER-06009: Error processing an FOI request.
Root cause:FOIServlet:null</oms_error>)'
When you say that we should use elocation for map tiles not for FOI rendering, does that mean that I should not use the themes provided by elocation. When I enter the base URL to a mapviewer instance in my map client, the base map and the themes are displayed from the database used by the mapviewer instance. So, how can I use my own mapviewer for FOI rendering? Can you please explain a little more. Thanks.

A bar graph problem

hi all,
sorry if my question is not clear, try my best to describe.
i currently creating a bar graph applet, where this applet take different "group" of data / value, e.g. (68, 268,2680, 28 and 8). and here the maximum value is 2680, other group may NOT so. so for being the bar graph display, i have an applet that has a "fixed" maximum width of 700, i need my bar graph to have only 10 columns and also i need to minus out 10 from each column for other purposes, so i take (700 / 10) - 10 = 60, but here come the real problem, if i take 268 * 60 = 16080, that is incorrect! That is i know that i had to divide the 700 with 1000, because (700 / 1000) - (10 / 1000) = 0.69, then 268 * 0.69 = 184.92, that seem OK! but, but it still ran out of the expected result, the bar width will be much more shorter than expected (only those higher data value), why? my code will be as follow:
   if (highestWidth >= 1001)
      maxDetector = 10000;
   else if (highestWidth >= 101)
       maxDetector = 1000;
   else if (highestWidth >= 11)
       maxDetector = 100;
   else
       maxDetector = 10;
   maxSingleWidth = (axisPanel.getWidth() / maxDetector) - (10 / (maxDetector / 10));so, at for loop:
for (i=0; i <= 9; i++){
   barPanel.setBounds(x, y, (dataValue * maxSingleWidth), height);
any help will be very very much appreciated!!!

Using bar graph

Hello,
Using obiee 11g,
I have a bar graph where i have put default height and weight.
Now the problem is i have my x axis based on a prompt because of which i can have my width bit dynamic.
My x axis is username
Whenever it takes more values i have seen that the some of the names are missing.
graph will be drawn but no names for some bars.
When i inc the width it becomes visible.
Is there a solution other then inc the width of the graph because everytime i cannot change the wdth of the graph and also i cannot predict how many users will be?
Thanks

Hello,
Thanks for the reply.
Then ill inc the width of the graph if there is no other solution.
One more thing wanted to know related to stacked bar graph the numbers on the graphs comes as overridden when i show them always i.e. Data labels,
if the stacked bar one above another is too close.
Is this way 11g behaves or is there any workaround.
Thanks

Legends on any bar graph

Hi
Please guide/ suggest how to get legends permanently displayed on the any bar graphs in the SOD Analytics dashboard. As of now the legends are visible only when the curser is on that bar.
regards
NSC

It's not clear if you are referring to Values or Legend, so I'll address both. You can find the options mentioned below in the chart Edit View (same applies for Pivot Table charts).
By default, the value of a bar will appear when you roll your mouse over it. If you want the value to appear permanently, then click the "Chart Properties" (pointy finger icon) and choose "Show Data Labels: Always".
Some chart types will not, by default, show a legend (indicating what each color stands for). To show a legend, you click on "Additional Charting Options" (arrow pointing right icon), choose the "Legend" tab and select the location for the legend to appear.

To draw bar graph

hi i am doing a portal there i want show the selected row in a bar graph format. is there any format or third party tool so that i can icorporate for drawing graph. nor should i alter my servlets code for it.

hello vijay,
i got one code from google about the drawing of the graph. after seeing that code , i think it will not take the data automatically it should manually.

Now we will create a html region to display the graph.
9. Create a new region of type HTML on the same page and select the region template as no template.
10. Enter the following code in the region source
<div id="DynamicaBarGraph"></div>
<script type="text/javascript" language="javascript">
function DynamicaBarGraph()
var DynamicaBarGraph = new AnyChart('/i/flashchart/swf/AnyChart.swf');
//    DynamicaBarGraph.width = "400";
//    DynamicaBarGraph.height = "400";
DynamicaBarGraph.addEventListener('pointClick', onDynamicaBarGraphClick);
    var DynamicaBarGraphData = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=DYNAMIC_BAR_GRAPH_CHART',0);
    gReturn = DynamicaBarGraphData.get();
    DynamicaBarGraph.setData(gReturn);
    DynamicaBarGraph.write("DynamicaBarGraph");
function onDynamicaBarGraphClick(e)
// Read point name
     name=e.data.Name;
// Read point value
     value=e.data.YValue;
// You can add onclick even here using the values name and value
DynamicaBarGraph();
</script> Hope it helps. Thanks.

Data display on Bar graphs - Needs help

Hi,
I am facing a problem with discoverer's bar graphs.
There is a 2D Bar Graph, which is required to display the respective strength for all the classes on the axis(e.g regionwise sales for North, West, East, South). In Oracle discoverer the sales is shown only when the mouse is pointed over the respective bar but that too at the bottom. The fixed values of the sales is not being displayed above each bar permanently.
But the client requirement is to display the strength for each class above each bar numerically so that a print out can be taken along with values.
Please suggest how can this be done.
Goga

On the Plot Area tab, check the "Show Data Labels for bars". To the right of that, clicking the "Options" button will let you place the labels above or in the bars.
Also, check that the graph background color is not the same as the font color.
