Standard error of mean for column/bar graphs

Hi,
Is it possible for me to have different standard errors in a column graph? (i.e. in a graph with 2 or more columns/bar to have their individual error bars drawn out?) So far I have only been able to have a single number for both columns in the graph.

V,
Numbers does the best it can with the information you give it. If you ask for Error Bars, Numbers will calculate the standard deviation for the series and assign that calculation result to each of the bars in the series.
If each of your values represents some statistic that in itself is accompanied by a standard error, that's another thing, but Numbers doesn't know what the error values are unless you tell it. The way to tell Numbers what the error bar values should be in these special cases is to use Custom values.
Here's an example:
I like to use the Scatter Chart, but you will find similar controls for the bar chart.

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.

What does system error 3409 mean for an hp officejet 720?(appears after power on)

Officejet 720(all-in-one
Pretty straight forward:
Printer powers on, seems to go through normal power-up, including noise moving cartridges back & forth, asks for date & time (skipped by hitting stop button) then this error appears (system error 3409) & unit becomes totally unresponsive.

This looks like a Paper Jam issue.
You can refer to this post which had a false paper jam issue which has similar symptoms as yours:

Group Stacked Bar Graph

Hi,
In our project we need to implement grouping of stacked bar graph, but with dvt graphs we are not able to achieve this.
We want similar graph in below link but using dvt graphs:
http://www.highcharts.com/demo/column-stacked-and-grouped
Please help me with grouping of stacked bar graphs.
we are using JDeveloper 11.1.2.3.0 for development.
Thanks,
Jasbeer

Hi lo,
I think all you need to do is implement the code found below. What you need is instead of using the random numbers (like in my example), you would just give it the values for you bar graphs. You can then build an array where you append the values for the second color above the first color by using the add function. If you then go into the plot legend (left click and go into bar plots), you can change the presentation of the data on the graph. You will also have to change the common plots display in the legend as well (left-click and go into common plots). I hope this helps!

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
Edited by: 973742 on Nov 28, 2012 8:12 AM

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}"

3d bar graph in CVI

Hi,
I am trying to determine if there is a 3D Bar Graph capability in CVI. I see that it is possible to create 3D surface plots and contour plots under the
AxtiveX libraries but I do not see one for 3D bar graphs. Is this possible?
I would like to basically create a 3 dimensional histogram whereby each 3d bar is equally spaced from it's neighbors, not continuous like a surface or mesh plot.
Thank you,
Phil Mulhall

Hello Phil,
As you mentioned, CVI provides a control for 3D graphs in the CWGraph 3D control. This control does not allow for 3D bar type graphs.
There is also the OpenGL instrument driver, but that does not seem to be able to create 3D bar graphs either. More information about the ActiveX control can be found here:
http://digital.ni.com/public.nsf/allkb/C6DD5A699FDD5EA5862570A100719B8E?OpenDocument
As for a 3D bar graph, I'm not aware of a way to do this. Sorry I could not be more help.
I'm aware that you have already had this answer via email, I am simply posting it here for other forum users who may have the same question.
Kind Regards,

Is there a property for mixed signal graphs to control Y scrollbar visibility?

Anyone know if it's possible? I can control the X-scale scrollbar visibility with a property but can't find one for Y-scale and have to do it from the front panel 'Visible Items > Y Scrollbar' context menu. I'd like to be able to configure it at runtime ... clues?

Hi Mike,
I read the property node for the bar plots (after having setting it by hand to the one you like) and it appears that the value of that bar plot is 8. I also set it to a different bar plot by and hand then wrote "8" to the property node and that does seem to change it to the last (left to right) vertical bar graph. I am running LV 7.1. If you look at the context help it does seem to indicate that the only values for vertical bar graphs are 1-3 but try writing "8" and see what happens.
Cheers,

CFCHART Interpolating Bar Graphs

CFCHART is interpolating when plotting bar charts. I can see
where interpolation would make sense for line charts, but not for
bar charts. I am plotting stacked bar chart series, and am getting
non-existant data appearing in the bar charts because of this
interpolation.
Can this be turned off? The default for a bar graph should be
to not interpolate.
I have been manipulating my dataset to explicitly add 0
values for the non-existant points, but that is a royal
pain.

You can alter the default chart style (or create a new chart
style) by editing the default.xml file in the
CFROOT\charting\styles folder.
I copied and changed the default.xml file and saved it as a
new xml style file. I then invoke the new style using the
<cfchart style="newstyle"... parameter where newstyle is
the name of the new file.
In the xml file itself, all you have to do is change the
isInterpolated parameter in the <frameChart tag> from
isInterpolated="true" to
isInterpolated="false"

Drag & Drop a Bar between two Bar Graphs

Hi,
I'm trying to move a Bar from barGraph1 to barGraph2.
Because dragSource operation is not valid for a Bar graph, I'm trying to use componentDragSource:
barGraph1:
<af:componentDragSource discriminant="ACDiscr"/>
barGraph2:
<af:dropTarget dropListener="#{DnDBean.adToWorkCenter}">
<af:dataFlavor flavorClass="oracle.adf.view.faces.bi.component.graph.GraphSelectionSet"
discriminant="ACDiscr"/>
, but method adToWorkCenter is not even called during the D&D operation.
I played also with attributeDragSource (if a single bar is object), but I cannot find what would be the corresponding attribute in this case.
Is it even allowed/possible to perform such operation on bar graphs? How?
Thanks a lot for support

JDeveloper 11.1.1.6.0

Hi Frank,
thanks a lot for the feedback.
I use JDeveloper 11.1.1.6 .... i think Drag & Drop between graphs shall be supported in this version?
http://www.oracle.com/technetwork/developer-tools/jdev/index-088099.html
"Drag and Drop: Graphs now support drag and drop within the graph, from one graph to another, or from a graph into another ADF Faces component such as ADF Table."
==
Since bar graph doesn't support dragSource operation, there is no way how to Drag bar from it?

Stacked BAR Graph

Hi Gurus,
Can somebody give me an idea, how do i use the GRAPH2d/ GRAPH3D function modules, to get a Stacked bar graph?
I have seen the GRAL transaction for examples, but i don't see any example for Stacked Bar Graph.
I would appreciate some help in this regard.
Thanks and Regards,
Ravi kanth

Hi Swathi,
I guess you don't get it in staked bar graph. because how can you identify A, B when C(0-300) is completely overlapped A, B ? use normal bar graph instead.
Thanks
Jay.

Solution for Messed (Error) Bar Graph of iPod Session in iTunes

I have encounter the error of iPod Session Bar Graph in iTunes like this:
http://img160.imageshack.us/img160/4527/capacitybarha6.png
and I find out the solution that can fix this problem!
Go to DEVICES > Your iPod > Music > Right click a group of file, and then [Get Info] > Options > Tick the box of [Gapless Album] and choose [Yes], wait for awhile for iTunes processing, and the Bar Graph restore to ordinary status!

Sounds like it has a drive collision with another device, would you happen to have an external drive or are you on a network, or do you have a printer with memory slots?
