Processing data from a bar graph

Hi,
I use JDeveloper 11.1.1.6.0
My VO contains 6 attributes. Two of them are displayed in a bar graph. I have created ClickListener bean, where I'm able to get X,Y values from selected bar (using methods getValue and getGroupAttributes from DataComponentHandle class).
Is it somehow possible to get also values from the rest 4 attributes, which are not displayed in the graph? I need to process these values programatically in my backing bean.
One way is to make a db query from my backing bean. Is there any other possible solution, without db access, just using data from ClickEvent?
Thanks a lot for ideas.
Daniel

I have solved this task in folowing way:
I have add ADF read only form to my page (which I need anyway). The form displays data selected in the graph (using another VO, which is linked to graph VO). Command button calls my managed bean, which handles the data via the bindings executables (view iterators).

  • Good for processing data from a web application?

    It seems like all the examples provided for ASA are about processing data streaming in from IoT or mobile apps. Is ASA appropriate for processing data from websites? For example, I have a multi-tenant web API and I need to roll up usage and calculate billing
    for my clients. My clients can upload resources with me which I store in blob storage. But blob storage gives me no way of knowing how many resources have been uploaded and how long I have stored them. Would ASA be a good fit for calculating these figures?

    I am using Reports 9i.
    I have created a Bar Graph in that It is showing the decimals bar. Actully in the query i hv used the inbuild function Round but while i run the report it is showing the decimals.
    It is showing if the value is under 10 then 3 decimals. Value is between 10 to 100 then 2 decimals. 100 to 1000 is 1 decimal.
    How can i remove the same.
    Also in the X axis how can I put the description of a field. While i take the description fiel it is showing some exception error.
    Description field width is 50 Now I am showing the code field only have 3 digits.
    Please check this also...

    Thanks in Advance

    Hi Simran
    1. You can get proper variable without decimal point.
    2. Use function "FLOOR" and get the output value assigned to variable defined in step 1.
    data : wv_wh_no type p decimals 0 .   -
    you take as per your requirement
    Let say,
    wv_dec_no = 1.0001.
    w_no = FLOOR(wv_dec_no).
    Hope it will help you.

  • 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.

  • Processing data from UI

    Hey,
    I'm writing a small program that takes user input from a client applet and sends it to the server where it is then processed and a response given. I set it up ok processing typed data at the command line but now I want to interpret clicks on UI components in an applet that I have created. How do I write directly to the client's output stream?
    For example if a user selects the left hand-side button on my client interface, this would create the sentence "left button clicked" like a protocol and then that sentence is passed to the server. Where upon the server receiving this sentence it is processed in some way. I know how to detect the click but it is the process of getting my client to inform the server of the event that I am struggling with.
    Thanks

    did you manage to set up a conn?Well when I start the server up it sits and waits for a connection, then I load the client and after the client has launched the listening server does correctly start up a server thread to handle the connection and this is confirmed with some output on the server's console. So it does know there is a connection. As to whether the server receives what I send I don't know, since my very question is how do I send :)
    When creating the command line version I had no problem, since the processing of text at the command line is automatically handled. I type something, press enter and the readLine() sees it and breaks the null while loop. However, now I am not typing anything, and I want to know how do I pass data. Can I send my data to an applet equivalent of the command line making it look like I have typed or do I do it some other way?
    How do I take care of the http tunelling?

    Hii,
           You can store the data as shown in the vi, just use the signal data by converting it into the numeric form and give it instead of random data.
    Hope this will help.

    Hi Sayaf
    It sounds like you need to use "Array Subset.vi" to split the 2000000 into 250000 element blocks.
    Set the index on Array Subset to 0 and then increment by 250000 after processing and displaying each block.
    Good luck

  • 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}"

    To determine id a point is inside of the red baloon it must satisfy the condition where the X,Y is less than any X,Y point and greater than any other X,Y point.   To filter them out remove outliers from the array or set their values to nan to not plot them
