Application Express :: Gantt Chart With Null Dates
Mar 28, 2013
APEX 4.0.2 Project Gantt Chart - Error Code: 2002 Message: Empty input
I found the actual dates are mandatory, while the chart tolerates missing planned dates - which is a complete reversal of what actual project data would have.baseline project gantt with parent-child relationship
What I found though is if some planned dates are missing, the generated XML seems to default with data from previous rows.my red lines indicate missing from/to dates (actual data also shown underneath chart) URL.....

why a Gantt chart would show only the first 15 rows of the query?! I validated id to be unique , parent_id properly pointing to the parent. When I artifically create another level, the chart still subborny shows only 15 rows. The actual query returns 1590 rows.

I have a 2D pie chart. The chart takes the column names as label and shows the results(3) like passed--4, failed--3, on hold ---6. Now I want to have tooltip , if I point on passed--4, it should show "number of students passed last year"similarlyIf I point on failed--3, it should show "number of students failed last year"

i need a chart with 4 lines and 2 y axis. 2 lines on the first y axis, 2 lines on the other y axis.First i tried to create 4 series and "multiple y axis", then i get the first line at one y axis, and all the other lines at the second y axis.
After that i have seen that it is possible to return more than one value within one series, so i create 2 series with 2 values each - i thought that then i will get the first 2 values at one y axis and the other 2 lines of the second serie at the second y axis... but sadly it is not like i expected - i get the same result as with 4 series.is it really necessary to create a custom xml for that?
here is my example: [URL] as you can see the blue and the red line are on different axis.the query of one serie looks like that (it gives the values of a day and the day before), the queries are ok.
select null link, to_char(a.ts,'DD.MM HH24:MI') label, sum(a.kw*100/12) over (
partition by trunc(a.ts) order by a.ts rows between
unbounded preceding and current row
) "KWh",
sum(b.kw*100/12) over (
partition by trunc(b.ts) order by b.ts rows between
[code]....

We have a pie chart which has select like
select null, '0-10' Days , count(*) from tableunionselect null, '11-20' Days, count(*) from tableunionselect null, '21-30' Days, count(*) from tableunionselect null, '>30' Days, count(*) from table
The 3d pie chart was showing the slices is the correct order 0-10, 11-20, 21-30, >30 but now shows it in random order. how to get the order by working. I suspect since the Days column in the select is a Character column this issue is occurring, however, with the restrictions in the number of select items we can have in the Apex charts, was wondering how do you get the order by working?

I am using the build-in flash Apex chart which I understand to be a subset of the Anychart.
I have the following problem, I have two series, which I am displaying in a 3D Bar Chart on a horizontal view with two Y-Axis. This works well, the problem is that each Y -Axis has a different scale. I am not setting the min or max value range for either of the y-axis as I do not know what this value range may be at the time of rendering the chart to the application user.
So as it turns out, the left y-axis has a value range from zero to 100 and the right y-axis has a value range from zero to 50 and the application users are finding this difficult and confusing as they are only looking at the bars represented in the chart and assuming that as the two bars, i.e. one form each series look similar in size, they have the same value and this can not be further from the true, as one y-axis is showing a value range twice as big as the other y-axis.
So my question is how do you customise the chart so that the value range on both y-axis is the same. i.e., the largest of the two?

I just noticed on apex.oracle.com (4.2) that I couldn't find the region source for flash charts. I expected to find it under the Region Definition tab.
Has this moved or will it be included in a later release?

I have created a few flash charts using APEX4.2. Is there a way for the user to view the chart and then email it as an inline image to someone? I know that the user can save the chart as PDF file, then send it as an attachment via Outlook ( or similar system), but can I integrate these manual steps to one ( template), similar to the IR report's download feature ?

I'm trying to create a histogram based on time range using a bar chart. I made the query correctly and the bar chart displays the histogram.
However I want to make the axes labels on the x-axis go under the tick marks of the axis. Right now they are under the corresponding bar. This doesn't convey the notion of a range. For e.g. if I have 23 observations between 10 and 20 seconds, I need to show 10 on the left of the bar and 20 on the right. In other words the bar is between two tick marks. I want to show 10 under the left tick mark and 20 under the right tick mark.
How do I do this? I tried using the attributes of the label tag under x_axis in the chart xml, but couldn't get it to work.

i I am using APEX4.2 and created
(1) a drop down list item called P38_DESK which contains a list of desks such as A, B, C
(2) a Chart region with region title: Chart Mvt by &P38_DESK.
(3) a dynamic action to "refresh" the Chart region if the value of P38_DESK is changed.
I can see that everytime the desk is changed from the drop down list, the chart section/region gets refreshed accordingly but NOT the Chart's region title.
It only showed the first value I chose. e.g. Chart Mvt by A So in APEX4.2, how can the CHART's region title be changed dynamically ( without submitting the entire page ) to reflect the value from the drop down list P38_DESK ?

The following query is used to generate a flash chart:
select null link
'Available' as "Available",
to_number(max_licenses - consumed_licenses)
from software_detail
where capture_date = trim(GET_CAPTURE_DATE)
and software_product = :p1
and software version = :p2
[code].....
But the 2d doughnut flash chart shows:
Available = 39
Consumed = 1
How is this possible?

I have an application which contains a chart of type Dial.In order to set the major interval dynamically I have switched to using custom xml and replaced the #SCALE_DATA# with:
<scale minimum='&P2_CHART_MIN.' maximum='&P2_CHART_MAX.' major_interval='&P2_CHART1_INTERVAL.'/>
However, I would also like to label the value with a Units Label (e.g. '%'). I was previously doing this using the Value: Postfix setting under Axes Settings, but after switching to Custom Settings removes this box and I no longer get the units displayed.
Is there some xml I can add which will set and display the units.I am using Application Express 4.0.2.00.09

issue with my apex line chart. The scenario is as follows: have a table called revenue. revenues per year are saved in it. and revenues are generated from three sources which are also saved in the same table. I have made a line chart on it. works well.
Now I have to show that if the value of one of the sources had fallen, how must have it affected the total. I made a number field that takes an estimated change value, and build my sql query with it. it works but the problem is that it changes the non-affected source too. it must change the value of the affected source only and hence the total value.
bold or I will put it this way, how can I write a select statement for a chart series so that one of the rows value does not change and the other two change.

I am using apex 4.1, i created a chart with 4 series in each series i am calculating sum of the no.of students joining in different classes of a institute for every year.
example my table is like this
date_of_join class student_id
'07/22/2012' 8 1
'07/22/2011' 8 2
'07/22/2009' 8 3
'07/22/2012' 7 4
'07/22/2010' 7 5
'07/22/2011' 6 6i wrote query like
series1
select null as link,UNISTR('�0A0') || to_char(date_of_join,'YYYY'),count(student_id) "class 8" from stdent_record where class=8 group by to_char(date_of_join,'YYYY') order by to_char(date_of_join,'YYYY')
series2
select null as link,UNISTR('�0A0') || to_char(date_of_join,'YYYY'),count(student_id) "class 7" from stdent_record where class=8 group by to_char(date_of_join,'YYYY') order by to_char(date_of_join,'YYYY')but what happened is the x-axis is coming in order like
2009 2011 2012 2010because the series1 no student is joined in 2010 so its taking the series1 order but i need the years in normal order.

I've edited the XML on the Chart Attributes page but I don't find atrtributes to rotate the y-axis title (<text>TITLE</text>) nor the letters themselves in the title. What I'd like is something very close to
T
I
T
L
E
But what I get is a horizontal title rotated -90 degrees. I've looked at lots of Anychart documentation but don't find anything that seems to fit with the XML already given on the Chart Attributes page. I've seen the "rotate" attribute but I don't know where it would go and even then, I'm sure it only rotates the title as a unit and not the individual letters.

We have generated a fancy custom interactive report, in which the columns of string type, but can hold string, numeric or date values. However the type of values are uniform for a particular column. The end users wants to use the numerical values for generating charts, but, being a string column (though the data is numeric), it throws an error and they could not generate the chart. Is there any way to make use of this string column type numerical data for generating chart?
The current version of apex is 4.1.

I have a query that selects multiple series for a bar chart (I have defined only one chart series, and have 3 columns selected to represent 3 series). The series display on Bar Chart is fine. Now I want to create a separate link target depending on which series is clicked on the chart. I am not able to do this.

I have a HTML region with two select lists and one button. The select lists are P103_SPORT and P103_YEAR. I want the user to make choices from the select lists and click the button to pass their choices as parameters in a URL. I set the button to redirect to a URL. In that URL I am using the notation &P103_SPORT. and &P103_YEAR. to include the user values. Currently when a user clicks the button, a new window opens with the URL, but nulls are being passed for the 2 items (sport and year). When I click the DEBUG button for the page, these items have nulls for values, even though the user selects values from the select list.
what I'm missing here? Why does DEBUG show null for the items when I can see values in these items?

Had some issues with a page on which i changed the value of an item using javascript and added a dynamic action (dummy pl-sql) that submitted the item. The problem was that if i also used $x_disableItem to disable the item in the function that set the value , the value submitted was always null. However if i used the "Disabled" attribute from the item Settings and remove the calling $x_disableItem in the function, the value submitted is correct.
To reproduce , create these objects on a page (default everything not specified):
<li>P1_VALUE - textfield
<li>P1_SET_VALUE - button calls "javascript:setValue();"
<li>P1_SUBMIT - submits the page
<li>Dynamic action:
- Event - Before Page Submit
- Execute PL-SQL (begin null; end;) - Page item to submit P1_VALUE
[code]....
So i have two questions:
1) Why is the implementation different (would have expected to behave in the same way)?
2) When using the javascript API function $x_disableItem , why is the value submitted null?
P.S: For the workaround i removed the $x_disableItem call with calling a custom function that toggles the read-only attribute of a given item.

I have a BI Suite implementation on one server. And a database with ApEx on another server.
I want to call a BIP report from within my ApEx application using the webservices (runReport) available in BIP 11g.
I used soapUI to test my webservice. Result : OK
When called from within ApEx, ApEx gives me a succes message but the report isn't generated. Instead the console on the BIP server shows the following error:
<Sep 12, 2012 10:28:37 PM BST> <Error> <org.apache.axis.encoding.ser.BeanPropert
yTarget> <BEA-000000> <Could not convert null to bean field 'sizeOfDataChunkDown
load', type int>
'sizeOfDataChunkDownload' is a field of the webservice that is left empty. That indeed is the only difference between my soapUI test and the ApEx situation. In soapUI I removed all empty fields. In ApEx this does not seem possible...
Some extra information:
- the webservice is created on this WSDL : /xmlpserver/services v2/ReportService?wsdl
- it's defined as a SOAP v2
- no basic authentication
- the reports are defined in the BIP environment; not in ApEx

Apex 4.1
Theme 21
I have select list which has null and other values. I have created a blank HTML region with the following text
Report for the year &P2_YEAR. and for geography &P2_GEOG.
Now P2_YEAR works fine because, it is always populated with a year. However, &P2_GEOG has 'All' as null value since we can see the report for all geographies. However, if the all option is selected, the above &P2_GEOG. shows as null. Since its not a PL/SQL proc, I cannot put in a NVL. I am guessing one possible way is to write a PL/SQL code before region and then check if its null and then try to populate a new hidden field and show, something like that. Wondering if there is a way to do it directly in the HTML region?
