Multiple Series Cluster Barchart locks up HTMLDB_PUBLIC_USER DB sessions

I am trying out cluster barcharts. I had a cluster barchart with two series. If I have no ORDER BY clause on the SELECT statements, the chart displays, but the bars are not clustered together correctly. I want all the bars from series #1 together and the bars from series #2 together ...
When I put an ORDER BY clause on the SELECTs in the two series, no chart is rendered. The chart region is blank. The problem is that the session connected to the database locks up/freezes. I refresh the page and now I have two sessions connected to the database stuck. When I refresh enough times we are unable to run HTML DB. The sessions run until they fill up TEMP tablespace. (I do not know why. The table they are running against only has 9 rows.) I had to go into the database with SQL*Plus and kill the sessions. Once these HTML DB session were killed, I was able to connect to HTML DB.
Questions
1) Is this a known problem with cluster barcharts?
2) How do I cluster the bars for each series together?

Hi,
if you remove "encryption mode ciphers aes-ccm tkip" from the radio interface does it help?
it should remain like this:
interface Dot11Radio0
no ip address
no ip route-cache
encryption vlan 1 mode ciphers aes-ccm tkip

  • Multiple series chart with differing dates

    Is there a way to display multiple series on a chart when the
    data for the horizontal axis doesn't match up? For example:
    if data1 (val, date) is (10, 01/05/2008) (15, 02/08/2008)
    (20, 03/01/2008)
    and data2 (val, date) is (8, 01/12/2008) (25, 02/10/2008)
    (30, 03/14/2008)
    how would I get the data to display on a multiple series
    chart. Right now, I am using a CategoryAxis for the horizontal
    axis. If I do something like this:
    hAxis.dataProvider = data1;
    hAxis.categoryField = "date";
    it will show only the series for data1, but not data2.

    Thanks for the reply.
    That link tells you how to add multiple axis to a chart which
    is what I'm doing, but unless you want to have two horizontal axis
    on the bottom (which looks terrible) or put one on the top and one
    on the bottom (which looks awkward), this solution is not very
    good.
    The problem is that the data ranges for the horizontal are
    the same, but the individual timestamps are slightly different,
    sometimes off by only a few hundredths of a second.
    To attempt to work around this, I merged the two arrays, but
    that seemed to mess up the display of the data.
    Is there not a way to just draw the second series on top of
    the first without having to lock it to the axis? It seems like the
    answer is no when using the standard packages. But is there a way
    to override this and get it to draw properly?

  • Increase Bar width in Cluster Barchart?

    When I decrease the chart width the width of the bars decrease as well. How do I increase the width of the bars in a cluster barchart while decreasing the width of chart?
    I am trying to draw three bars. There is a lot of wasted white space on the chart, so I decrease the chart width. It automatically shrinks the width of the bars. I want the bars to stay big. I do not want them to scale down.
    Mike

    I will answer my own question.
    For the chart series I had set the "Maximum Rows" artificially high to 100 when the query would only be querying 21 rows of data. When the chart is generated, HTML DB scales the width of the bars automatically to reserve enough horizontal space for 100 bars worth of data even if there is only 21.
    So all I did was set the "Maximum Rows" to 21 and the width of the bars set correctly.

  • Drill Down for Multiple Series in a Line Chart

    Hello,
    I seem to have a problem with the drill-down functionality in a line chart that has multiple series.
    I have a line chart that displays the readings of a patient over a period of 1 month. For each day, there is the glucose level reading, blood pressure reading, etc... So, each reading is a different series in my line chart graph.
    The basic requirement is: With a mouse over event on the chart, I am willing to display all the data that belongs to that day. The data will be displayed at the bottom of the screen in a small panel. It is very simple to do it when the line chart has only 1 series:
    i) Enable drill down.
    ii) Choose 'Row' as insertion type.
    iii) Fill out the destination field.
    iv) Make sure your labels (at the bottom of the screen) get the data from the destination cell.
    When there is more than one series, it becomes very difficult. XCelsius will not let me use the same destination cells for different series. So, I will have to use other destination cells. In that case, I will not know on which day is the user on. Is there any way to achieve this functionality?
    Let me know if you need further information.

    This is certainly possible, but there's a bit of a trick to it (and really hard to explain without screenshots!). There's two halves to it:
    1. Write the date that has been selected to a cell (for each series).
    2. Write the name of the series that was clicked to some cell (this is the property 'Series Name Destination').
    So let's say your three series are Glucose, Blood Pressure and Temp. Have those series names in B1,C1,D1 (with your dates down in column A). Insert a row below the series names (2:2), and then set up your insertion type for the chart as 'row'. The source data (for all three series) should be your list of dates in column a. The insertion cells for the three series will be, in order, B2,C2,D2. Now, depending on which point is clicked in the chart, the selected day will be inserted into one of those three cells. Completely useless unless you know which series was clicked.
    So you need to insert the name of the series that was clicked ('Series Name Destination') into the spreadsheet, let's say in F1. The rest is just Excel formulas. The logic is, you can now tell what series was clicked, and go and look up the date that was inserted for that series, then go and look up the row that corresponds to that date. So to get the date that was just clicked, your formula (in F2) would be =HLOOKUP(F1,B1:D2,2,0).
    Then a VLOOKUP will get the results from that row of data. For example, if I inserted another row at row 3 (to show my 'result' values) the formula in B3 would be =VLOOKUP($F$2,$A$4:$D$13,2,0).
    I hope that makes sense.

  • Candlestick chart problem with multiple series

    Hello,
    I added one mx:CandlestickSeries object and couple additional
    mx:LineSeries objects to the chart. All series are represented but
    still I have one problem. More series I add - less candles are
    becoming of CandlestickSeries data. It seems that there should be
    any scaling option for all series in the chart or something like
    this, but I cannot find it. I'm still new in Flex Can anyone halp
    me with this?
    Thanx in advance
    marukas

    I've added screenshots to get better view of the problem.
    Here is chart with addtional series:
    Chart
    with multiple series
    And here nothing is changed except that additional line
    series were removed:
    Chart
    with only one CandlestickSeries
    Is it possible to get the same candles as in 2nd view with
    addiotnal series added?

  • Stacked Bar Chart with Multiple Series Sort Question

    Hi,
    Apex version 4.1.1
    I have a stacked bar chart with three separate series, one showing customer effort, another showing project effort and the third showing other effort, summarized by calendar week. The x-axis of the chart is the calendar "week of" date, and the y-axis has a bar for each of the three series. Not every type of effort occurs every week.
    When AnyChart renders the chart, the order of entries on the x-axis seems to be dependent both on which series are present in a given week as well as the "week of" date. Weeks with all three series sort in order by calendar date, followed by weeks where just the 2nd & 3rd series are present, followed by weeks where just the 3rd series is present. See this [url http://tinypic.com/r/b9zdt/6] picture of the chart  noting the "week of" dates. Note that the months go Sep-Oct-Nov-Aug-Oct.
    Is there a way to force AnyChart to sort the x-axis in chronological order regardless of whether there is data for all three series for a given week? I have looked through the AnyChart XML reference but cannot find a way to do this.
    Incidentally, I can solve the sorting problem by combining all three series into a single query:
    select
      null as link,
      week_of as label,
      sum(customer_effort) as "Customer Effort",
      sum(project_effort) as "Project Effort",
      sum(other_effort) as "Training, Admin and Other Effort"
    from ...But if I do this, I cannot figure out how to have each bar on a given week link to a different detail page, e.g., if I click on a bar representing customer effort I want to link to one page, but if I click on a bar representing project effort, I want to link to a different page. I have had a look at the [url http://apex.oracle.com/pls/apex/f?p=36648:59:1570983160946101::NO:::] chart examples  posted on apex.oracle.com, but cannot figure out how to apply to multiple series in a single query.
    Thanks,
    Mike

    Thanks, Jeff. I did try this but for whatever reason it doesn't make a difference. I think it is because if there's no data for a given series for a certain week, there is no entry in the data set that is sent to AnyChart.
    I was able to get around the issue by "filling in" the missing weeks from each data series. To generate the list of "Week Of" dates for a given date range, I used this code:
    select
         trunc (each_day) as week_of,
         0 as effort
    from (
         select
              (to_date(:p920_start_date,:app_date_format) + 2 - to_char(to_date(:p920_start_date,:app_date_format),'D') - 1) + level each_day
         from dual
         connect by level <= to_date(:p920_end_date,:app_date_format) - to_date(:p920_start_date,:app_date_format) + 1
    where
         to_char (each_day, 'D') = '2'This creates an effort entry of 0 for each week within the date range; I use the Monday date of a week as the "Week Of" date. I then union this with my actual data and summarize by week and viola, I get the weeks in order. This also has the benefit of showing a week for which there are no entries in any of the three series.
    Thanks for taking a look at this.

    I've run into this, too:
    Remove the fills property from each ColumnSeries and it'll work.
    If you want to use the fills property, you'll have to add your own custom legend code.
    From the Flex API:
    "If you specify the fills property and you want to have a Legend  control, you must manually create a Legend control and add LegendItems to it."

  • Annotating ColumnChart using CartesianDataCanvas - multiple series

    I am trying to annotate a column chart with confidence
    interval bars using the CartesianDataCanvas. The chart has multiple
    series, so for each x value there may be four or five columns. The
    chart itself offsets these columns nicely, but the x value used in
    the CartesianDataCanvas only relates to the middle of the middle
    bar. Is there any way of working out what offset to use to match an
    annotation to each individual bar when there are multiple grouped
    bars? I can't seem to find a property that has this
    information.

    This seems to work, how cool!

  • Multiple series in a chart

    Hi
    I want to create a chart with multiple series, each serie referring to a specific country.
    The query below is not accepted:
    SELECT null url,s.date_from,s.country,sum(s.unique_players) unique_players
    FROM   my_table s ...As a workaround I changed the query to:
    SELECT null url, s.date_from,
    sum(decode(s.country, 'se', s.unique_players, 0)) sweden,
    sum(decode(s.country, 'fi', s.unique_players, 0)) finland,
    sum(decode(s.country, 'no', s.unique_players, 0)) norway ...
    FROM   my_table s ...It works well but it is not very flexible, in the case a new country has to be added.
    Is there a better way to achieve this in Apex 3?
    Thanks
    Luis

    Luis,
    You can chart a variable number of series with a query like the second one you listed, except use "Function returning query" instead of "SQL query". Then generate the column list clause dynamically, one for each series.
    There's an enhancement request logged to make this easier.

  • Issue with min/max when vertical axis assigned to multiple series

    Hi.
    I have some simple charting code that is dynamically adding LineSeries to a chart as the user requests them from the gui. As each series is added the vertical axis is assigned to the series and then data is requested and assigned to the dataProvider on the series. This is all working fine however I have found that if I add a sceond series after the first series is displayed and assign the same vertical axis to the second series then the vertical axis seems to set teh min/max based only on the second series added and ignores the first series. It doesnt set to the max of both series and so I get an incorrect max set. If I add a 3rd series the same happens again and the first and second series values seem to be ignored and the axis is set based on the last series to be added.
    Is this expected? Ive tried different variations of invalidating the data/series/styles to force it to refresh but I always get the same. It does refresh but based on only the values in the last added series.
    What is odd is that if I add 2 series at the same time, and assign the axis to both of them and then request data for both and update the dataProvider on both of them the axis is configured correctly based on the max value of both series.
    Any workarounds to make it do the right thing if they are added dynamically? Is this a bug or a known "feature"?
    Any light anyone can shed would be appreciated.
    I need to have the axis assigned to the series directly as I want to be able to use multiple axes. I have found that if I set the verticalaxis on the chart rather than the series then it works fine and sets the min/max based on the combined values of both series.
    The vertical axis is just a simple LinearAxis.
    Any help or suggestions would be appreciated.

    Adobe Flex LiveDocs seemed to indicate "Using multiple series in the same chart works best when the data points are in a similar range (such as a stock price and its moving average). When the data points are in numerically very different ranges, the chart can be difficult to understand because the data is shown on a single axis. The solution to this problem is to use multiple axes, each with its own range. You can plot each data series on its own axis within the same chart using the techniques described in Using multiple axes" and that link is here:
    http://livedocs.adobe.com/flex/3/html/help.html?content=charts_types_11.html
    I was going to tae a look at this myself, but the code posted here is quite complex, and I suspect incomplete.
    If you refer to that link and still cannot solve the issue, I would try your best to boil down your code to a more simple example still exhibiting the issue, and then post that, along with any data and the simplified main app.

  • Multiple series on anychart line graph?

    I want to set up an anychart line graph from a query which returns a result set something like:
    PART DATE QTY
    abc 01/01 10
    abc 02/01 20
    abc 03/01 10
    cde 05/01 10
    cde 06/01 20
    So, in the above I want a series for part abc and part cde. I know I can add another series but that has two problems:
    1) The number of distict parts can vary - there might be 2, or might be 20 depending on the parameters used.
    2) Adding a new series means duplicating pretty much the same query manu times (with a restriction on part number) - this is very inefficient!
    Is it possible to add multiple series "programatically"?

    Ah, I never saw the number 10 anywhere.
    You don't need to process the NaN with mathscript. It is sufficient to add the NaN to the data going to the graph terminal. Even if mathscript gets an NaN, you can probably test how it is handled.
    What does the mathscript node actually do? If it is just doing some scaling, it probably will not matter, but if it would do e.g. a linear regression, it would probably give unexpected results.

  • SVG Linecharts with Multiple Series

    I've been trying to get multiple lines/series on a linechart. I have a query which works okay to get the first series. A slightly different query (or the same query, even) makes it barf and give me an error. I'm using HTMLDB 1.6
    What's especially irritating is that there's next to no documentation for this thing. The manual and the how-tos give a couple small examples for various types of charts. It's never revealed anywhere what kind of query it's looking for in every type of chart, and the vague error messages and the neat-nonexistant documentation don't help in the slightest. Does anybody here really use this thing for actual development?
    Sorry. Frustration aside, is there anybody who has managed to get this to work? I've been trying to get it to work for a few days now, as has a co-worker, and I'm getting nowhere. I might go and try it on my HTMLDB 2.0 demo account and see if maybe this kind of thing is fixed or at least better explained.

    Dan,
    I used line charts to show trends in report usage in an application I support. Basically the line chart can have multiple series (lines) on it. Each series has a unique query. All series queries are of the form:
    SELECT link, label, value FROM table
    - 'link' is an URL used for drill down. This could be another page in your application with a details report. When the user clicks on the line for the series, HTML DB takes a branch to this link.
    - 'label' is the value for the x-axis. In my case this was a month of the year.
    - 'value' is a numeric value to be plotted on the y-axis.
    For example if you had a STOCK_QUOTES table the series query to track how Oracle's stock is doing would be:
    SELECT NULL link, closing_date label, price value
    FROM stocks
    WHERE symbol = 'ORCL'
    If you wanted to track other software companies stock on the same chart, just add another series changing the literal 'ORCL' to some other value.
    Note: if you have more than 15 rows in your series query, make sure you increase the 'Maximum Rows' for the series to an appropriate value.
    I hope this helps,
    Mike

  • Plotting multiple series on an SVG Chart

    Hi,
    I am trying to plot multiple series on an SVG Chart. The moment I add a second series, I get the following error:
    "SVG Chart error: ORA-20001: line_chart error: ORA-20001: get_data error: ORA-20001: Parse error: ORA-0093".
    The graph fails to plot multiple series even for the same queries. The query I use is something like the following:
    select null "link", substr(name,7) "Label",value "Value"
    from <table>
    where
    <conditions>
    and name in (<sub-query>)
    order by name desc
    I have previously used an SVG chart to plot multiple series and have never had such problems. Any help would be greatly appreciated.
    I tried deleting and recreating the chart - doesn't help.
    Thanks,
    Aswath

    If you want to order the data do it via an in-line view:
    SELECT *
    FROM (
    select null "link", substr(name,7) "Label",value "Value"
    from <table>
    where
    <conditions>
    and name in (<sub-query>)

  • Query - Sharing single Input/output  FRS  across multiple CMS Cluster

    Hi,
    I have two BOE XI R2 SP3 servers on windows 2003r2 x64 which are with one BOE clustered, sharing file repository (FRS) on common NAS storage folders. Objective is to vertically scale BOE servers by adding more clusters on these two BOE servers. I wish to add few more clusters by adding CMS through CCM wizard option pointing to separate CMS db sachems.
    Can multiple CMS cluster share same FRS component with separate folder structure OR do I have to duplicate each BOE component per cluster basis.
    Regards,
    G.

    Hi
    Thanks for your response.
    Hardware allocated for BOE is only 2 servers, and design is to maintain 3 separate environments( One change should not affect other). We wish to share Production, Testing and support BOE environments on same hardware.
    Only objective of maintaining multiple BOE cluster on same hardware is to provide non inter dependent BOE service to various user groups.
    Suggest needful
    Regards,
