Add dinamically series to a chart

Hi all,
Is there any way to dinamically add series to a chart? I.e. based on the results of a query by using pl/sql or api or similar.
Many thanks

Hi Javier,
why don't you use the Query Source Type="Function Returning SQL Query" feature of the series?
Create 1 series with the above type and depending how many columns you return in your chart query that many series you have. Or do I miss something?
eg.
DECLARE
    vQuery VARCHAR2(32767);
BEGIN
    vQuery := 'select null, to_char(o.order_timestamp, ''MON RRRR'') label, ';
    IF :P1_OPTION = 'NO CLUE'
    THEN
        vQuery := vQuery || 'sum (decode(p.category,''Computer'',oi.quantity * oi.unit_price,0)) "Computer",
                             sum (decode(p.category,''Video'',oi.quantity * oi.unit_price,0)) "Video" ';
    ELSE
        vQuery := vQuery || 'sum (decode(p.category,''Computer'',oi.quantity * oi.unit_price,0)) "Computer",
                             sum (decode(p.category,''Audio'',oi.quantity * oi.unit_price,0)) "Audio",
                             sum (decode(p.category,''Phones'',oi.quantity * oi.unit_price,0)) "Phones" ';
    END IF;
    RETURN vQuery ||
           'from demo_product_info p, demo_order_items oi, demo_orders o
           where oi.product_id = p.product_id
           and o.order_id = oi.order_id
           group by to_char(o.order_timestamp, ''MON RRRR''), to_char(o.order_timestamp, ''RRRR MM'')
           order by to_char(o.order_timestamp, ''RRRR MM'')';

Programitically creating column series to flex chart not showing the chart

I want to create n number of series dynamically when i run my
application.
where n can be any value it depends on the data which i
retrieve from database. below i pasted the example
( in this example i have taken n = 4 i.e., CountMax=4 if i
change the CountMax=6 then it should generate 6series dynamically
after calculating the values. ). just copy the below code and paste
it in Flex builder and run the application.
in this example i am facing problem, chart series are not
showing. i dont know the reason why its not showing, if anyone got
the solutions for the problem please let me know. my actual
requirement is to retrieve data from Salesforce account and want to
populate the arraylist then display the chart.

How to add line series dynamically to a line chart in flex?

hi..i need to add line series dynamically to a line chart..depending on an array..the application is this..i have an array which stores the details of the users connected to an fmi server..the chart should display the bandwidth of each client..so the users should be added and removed from the chart dynamically...

Hi
1.I am giving you solution for dynamically adding values to the dropdown
public void addValue( ) //Method Name in Component controller
    //@@begin addValue()
          IWDNodeInfo nodeinfo = wdContext.nodeNodeTestData().getNodeInfo();// Node should be map to the view's Node
          IWDAttributeInfo att = nodeinfo.getAttribute("VechileTypes");// Attribute by which dropdown in bound//
          IModifiableSimpleValueSet svSet = att.getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();
          svSet.put(wdContext.currentNodeTestDataElement().getInpAtt(),wdContext.currentNodeTestDataElement().getInpAtt());
    //@@end
2.   wdThis.wdGetLangCompController().addValue(); // call this method in the point where u want to add values to the dropdown.

Add series to existing chart

I have a chart in its own sheet. The chart has one series from another sheet. I'd like to add a series from yet another sheet, but can't figure out how. I can't drag the new series to the chart... thoughts?

From the user's manual:
To add a chart based on data in more than one table, first select a single table or
contiguous range of cells and create a chart, then click Charts in the toolbar, and
choose a chart type. Select the chart and hold down the Command key while clicking
or dragging cells in another table to add their data to the chart.
Whoops, that won't let you choose from different sheets, just different tables on the same sheet.
Maybe there's an easier way but what I found would work is to create the chart in the first sheet then cut and paste it into the other one so you can select the second set of data.

Series Implementation in chart components

Hi Everybody,
I want to design a custom line chart component for xcelsius. Unfortunately I could not add series to my chart component as it implemented in xcelsius line chart. I am new to xcelsius and I am not getting idea, when I will modify a property in component, how it will reflect in the property sheet. I don't know how the series part works in xcelsius components and each series holds its respective data.
Please help me.
Thanks.

Let me explain you with a simple example:
Data:
         Product 1, Product 2
2007, 10          , 20
2008, 30          , 50
2009, 40          , 60
Drag and drop line chart on canvas, and go to properties of the chart.
Select radio button By Series and click +
Name: Product 1
Values(Y): select the cells under product 1 i.e. 10, 30 and 40
Category Labels(X): Select cells that contains year i.e. 2007, 2008, 2009
Click + to add another series
Name: Product 2
Values(Y): select the cells under product 1 i.e. 20, 50 and 60
That's it...save and preview...you will understand how the series in this chart works.

Function returning SQL query for mutiple series in a chart

Hi,
I would like to know if there is a way to specify a single PL/SQL function returning the queries for multiple series in a 2D Line Flash Chart. I have multiple series in my chart that has different values in the where clause. I can write a PL/SQL function that can return all these queries in one shot. Is there anyway that I can specify this function as returning the queries for all the series in the chart?
As an example, assume that I am using the following three queries for the series in my chart:
select deptno, count(*) from emp where deptno = 10 group by deptno
select deptno, count(*) from emp where deptno = 20 group by deptno
select deptno, count(*) from emp where deptno = 30 group by deptno
I can't write a PL/SQL function that returns a query in the multiple series syntax (SELECT link, label, series_1_value [, series_2_value [, ...]]FROM ...) as I am using an aggregate function and my where clause is different for each series.
Thanks,
Rupesh

Hi Roel,
Thanks for your reply. I am already using an analytical function (RATIO_TO_REPORT(COUNT(*)) OVER () ) in my actual report. My problem is that the query for one series differs from the other only in one where clause. I will be able to dynamically able to generate all the queries for all the series in one pl/sql function. But the chart definition screen does not allow us to define a single function that returns queries for the all the series - possibly seperated by some seperator like S1: select.... S2:select and so on.
Regards,
Rupesh

Scatter plot using time series function - Flash charting

Apex 3 + XE + XP
I am trying to build a time series scatter plot chart using flash chart component.
Situation :
On each scout date counts are taken within each crop. I want to order them by scout dates and display them in a time series chart. Each series represents different crop.
I am posting the two series queries I used
Queries:
Series 1
select     null LINK, "SCOUTDATES"."SCOUTDATE" LABEL, INSECTDISEASESCOUT.AVERAGECOUNT as "AVERAGE COUNT" from     "COUNTY" "COUNTY",
     "FIELD" "FIELD",
     "VARIETYLIST" "VARIETYLIST",
     "INSECTDISEASESCOUT" "INSECTDISEASESCOUT",
     "SCOUTDATES" "SCOUTDATES",
     "CROP" "CROP"
where "SCOUTDATES"."CROPID"="CROP"."CROPID"
and     "SCOUTDATES"."SCOUTID"="INSECTDISEASESCOUT"."SCOUTID"
and     "CROP"."VARIETYID"="VARIETYLIST"."VARIETYLISTID"
and     "CROP"."FIELDID"="FIELD"."FIELDID"
and     "FIELD"."COUNTYID"="COUNTY"."COUNTYID"
and      "INSECTDISEASESCOUT"."PESTNAME" ='APHIDS'
and     "VARIETYLIST"."VARIETYNAME" ='SUGARSNAX'
and     "COUNTY"."COUNTNAME" ='Kings' AND CROP.CROPID=1
order by SCOUTDATES.SCOUTDATE' ASC
Series 2:
select     null LINK, "SCOUTDATES"."SCOUTDATE" LABEL, INSECTDISEASESCOUT.AVERAGECOUNT as "AVERAGE COUNT" from     "COUNTY" "COUNTY",
     "FIELD" "FIELD",
     "VARIETYLIST" "VARIETYLIST",
     "INSECTDISEASESCOUT" "INSECTDISEASESCOUT",
     "SCOUTDATES" "SCOUTDATES",
     "CROP" "CROP"
where "SCOUTDATES"."CROPID"="CROP"."CROPID"
and     "SCOUTDATES"."SCOUTID"="INSECTDISEASESCOUT"."SCOUTID"
and     "CROP"."VARIETYID"="VARIETYLIST"."VARIETYLISTID"
and     "CROP"."FIELDID"="FIELD"."FIELDID"
and     "FIELD"."COUNTYID"="COUNTY"."COUNTYID"
and      "INSECTDISEASESCOUT"."PESTNAME" ='APHIDS'
and     "VARIETYLIST"."VARIETYNAME" ='SUGARSNAX'
and     "COUNTY"."COUNTNAME" ='Kings' AND CROP.CROPID=4
order by SCOUTDATES.SCOUTDATE' ASC
Problem
As you can see the observations are ordered by scout date. However when the chart appears, the dates dont appear in order. The chart displays the data from crop 1 and then followed by crop 4 data, which is not exactly a time series chart. Does flash chart support time series or they have no clue that the data type is date and it should be progressive in charting ? I tried to use to_char(date,'j') to converting them and apply the same principle however it did not help either.
Any suggestions ?

Arumugam,
All labels are treated as strings, so APEX will not compare them as dates.
There are two workarounds to get all your data in the right order:
1) Combine the SQL statements into single-query multi-series format, something like this:
select null LINK,
"SCOUTDATES"."SCOUTDATE" LABEL,
decode(CROP.CROPID,1,INSECTDISEASESCOUT.AVERAGECOUNT) as "Crop 1",
decode(CROP.CROPID,4,INSECTDISEASESCOUT.AVERAGECOUNT) as "Crop 4"
from "COUNTY" "COUNTY",
"FIELD" "FIELD",
"VARIETYLIST" "VARIETYLIST",
"INSECTDISEASESCOUT" "INSECTDISEASESCOUT",
"SCOUTDATES" "SCOUTDATES",
"CROP" "CROP"
where "SCOUTDATES"."CROPID"="CROP"."CROPID"
and "SCOUTDATES"."SCOUTID"="INSECTDISEASESCOUT"."SCOUTID"
and "CROP"."VARIETYID"="VARIETYLIST"."VARIETYLISTID"
and "CROP"."FIELDID"="FIELD"."FIELDID"
and "FIELD"."COUNTYID"="COUNTY"."COUNTYID"
and "INSECTDISEASESCOUT"."PESTNAME" ='APHIDS'
and "VARIETYLIST"."VARIETYNAME" ='SUGARSNAX'
and "COUNTY"."COUNTNAME" ='Kings'
AND CROP.CROPID in (1,4)
order by SCOUTDATES.SCOUTDATE ASC2) Union the full domain of labels into your first query. Then the sorting will be applied to the full list, and the values of the second series will be associated with the matching labels from the first.

How to remove series from a chart?

Hi,
I want to remove a serie from a chart with 2 series. I've tried app.columnChart.removeChild(app.columnChart.series[1]);
to remove the second serie, but it doesn't work. The error it writes is:
The supplied DisplayObject must be a child of the caller. Please help.

Thanx for reply.But this is not what i am looking for.I need
to apply different colors for each bars.I am generating charts
dynamically.The item renderer is working fine.But at specific
condition the item renderer shold ne removed from the chart series

Hiding series in a chart

Title says it all. I don't know how I can hide certain series
in a linechart. Searched the docs and different sites, but I just
can't find a method to do it. Setting the alpha of a serie to 0 is
no option because the datatips will still popup.
To make it more clear, watch
[url=http://www.wowhealers.com/healbot1.40.html]this
application[/url]. Clicking the black dots there also hides a
certain serie.
Thanks in advance :)

I think you only have two options: use the alpha as you have
done and use your own function or class to handle the dataTips,
preventing the ones you don't want to show up from appearing. Or
remove the series from the chart (you don't have to destroy it,
just remove it and it can be added back).
The problem with the latter is that, say you have 3 clustered
series so there are 3 bars showing up. If you remove a series, the
other 2 bars spread out to occupy the remaining space.
If you still want to go with the alpha solution, try setting
enabled="false" on the series. I have no idea if that will work,
but if it does and you have set the alpha to 0, then it should
prevent the data tips from appearing and you won't have to write
some function or class to handle it.

4 series in a chart setup

I have 4 series in a chart and I want to have 3 using the left axis and 1 using the right, how can I set this up?
thanks

Select the chart then the series to delete by clicking on the series' header. It should look like this:
Then use the delete key. You're right, the "Edit"/"Delete" is not enable. This is probably a bug.
Message was edited by: 5|=vv... clicking on the series in the chart, while it selects the series does not then allow deletion (probably another bug).

How to provide different plor series for plot chart

How to provide different plot series for a Plot Chart.
The IDs of the series are given in a ComboBox control

Series are stored in an array. If there is only one series, then you can change it simply by "pushing" a series into a new array, and then assigning that series array to the chart. If you are replacing one series in the chart series array, then you have to figure out which to remove and put the new one in.

How to add two series data in singal xy graphs in excel through labview

Hi,
I am trying to generate excel report and needs to plot XY graph in excel sheet. Using excel insert graph VI I am able to pass the data to excel and generate the XY graph (one x axis and many y axis), but I am not able to add a series in the graph that means not able to plot two XY plot in same graph (for example two plot X1Y1 and X2Y2 on same Graph). I know the other options like passing the image of graph control to excel sheet and by passing the data to specified cells and generating the xy plot.But my requirement is plotting xy plots in singal xy graph without displaying the data in tabular form in excel sheet. (Like when we call the insert graph VI, it will only inserts the OLE object and data is hidden in that) Please let me know if you need more clarification and let me know how to do this..

I have got answer from another post. Thanks.
