Scheduling and gantt charts with Apex?

Hi,
Has anyone created Gantt charts using Apex?
Also, has anyone used Apex to create schedules?
From what I can tell, Javascript would be the language to use to add such code to an Apex app, correct?
Regards,
Daveio

Leo,
Thank you, I appreciate the help!
An example of what I would like to do with scheduling:
- Jobs will be entered into the application with priorities, durations, and required resources
- The application will determine when the jobs can be started based on priority and resource availability
- If a priority is changed the job start/finish dates should change accordingly
This is the information I would like to have displayed on a Gantt chart. I have a text explaining several scheduling algorithms that will help make this possible but I will need to learn how to write the code into Apex.

Gantt Charts with APEX

Hello
Has anybody managed to integrate Gantt Charts with APEX and got them working. I'm required to provide some similar reports.
I understand Gantt charts are available in AnyCharts 5 but I need the XML to convert or at least a How To Do document.
Any any other ideas would be appreciated.
Cheers
Ade

Hi Ade,
We have built an Anychart Integration Kit for APEX, if you take a look at -
http://anychart.apex-evangelists.com
and specifically -
http://anychart.apex-evangelists.com/pls/apex/f?p=454:14:0:
You'll see that anything is possible ;)
We've concentrated on the core Anychart Functionality in the Integration Kit and will be releasing more powerful versions shortly.
Hope this helps,
John.

Gantt chart with duration

Hi Experts
As a part of bidding, client need to produce Gantt chart to the customer.
However, since this is presale process, the exact dates are not indicated but the duration of project to be specified. It means the schedule to show the duration from zero date.
Is it possible to take print of Gantt chart with out dates but duration of individual activity or WBS?
Warm regards
ramSiva

Hi Ahmed
Thank you for your reply.
The time scales in Gantt chart specifically shows the year, month and weeks from the start date of project definition or basic start of WBS.
Since it is not a decided project, the Gantt chart need to show 0, 1st week, 2nd week, 3rd week etc.
The actual schedule from PD start date can be produced on actual initiation of project.
It means, i am looking for having Gantt chart for duration and not for specific start and finish dates.

Posible bug building gantt chart in apex 4

Hi fellows,
When building "Project gantt" chart in apex 4 enter the following query:
select 'null' ,
'Proyecto X' ,
1 ,
null,
sysdate ,
sysdate+10 ,
0
from dual
I picked up the parameters from the "Chart query example" and the following error displays:
*1 error has occurred*
** Invalid Gantt chart query: Wrong here:12*
Use the following syntax:
SELECT LINK, ID, TASK_NAME, START_DATE, END_DATE, STATUS FROM ...
LINK     Action Link
ID     Task ID
TASK_NAME     Text that displays along a chart task.
START_DATE     Date column that specifies the actual start date of the task.
END_DATE     Date column that specifies the actual end date of the task.
STATUS     Numeric column that specifies the percentage of progress made for the task.
or
SELECT LINK, ID, TASK_NAME, START_DATE, END_DATE, STATUS, PLANNED_START_DATE,
PLANNED_END_DATE FROM ...
LINK     Action Link
ID     Task ID
TASK_NAME     Text that displays along a chart task.

PLANNED_START_DATE     Date column that specifies the planned start date of the task.
PLANNED_END_DATE     Date column that specifies the planned end date of the task
As you can see the parameters are diferent ¿? !, I have tried both (lots of variations) but nothing appears to work.
Is this a bug or am I wrong?.
Can u post a simple query like mine that works please?
Thx 4 your help.

Hi Marco,
Just to clarify, tryapexnow.com is running Oracle APEX 4.0 EA3, and http://apex.oracle.com is running Oracle APEX 4.0 Pre-production.
You are correct, the syntax outlined in the error message is incorrect, and I've logged bug *9799373* to track this. As a workaround, you can view sample syntax for Gantt charts on the 'Query' page of the Create wizard, in the 'Chart Query Example for Gantt' Show/Hide region below the text area for entering your chart query, and also in the Oracle APEX 4.0 User's Guide that will be available with our new release. Just in case other users hit the same issue and are unsure of the expected format:
Chart Query Examples for Project Gantt Charts:

How to build a gantt chart with BI Publisher

Hi everybody, I need to create a gantt chart with BI Publisher. I had a look to the document "Getting Gantty" from the blog:
http://blogs.oracle.com/xmlpublisher/2008/01/getting_gantty.html
but I don't understand in which way:
1. build the data template in order to replicate the XML code in the article
2. build and link the yellow bar which dynamically increases its length according to the meeting duration
Anybody already tried to implement something similar ? I didn't still found a real example about how to do it......
I need a help, please
Thanks in Advance
Alex

Yes that is the only option which we can stop a running report in BI Publisher
I suspect you'll need to ask your DBA to kill the session.
However, if you have DBA privileges yourself, you can do this by a few methods, some of which are described here:

AnyChart Radar chart with APEX

Hi all,
I need to create Apex application that requires page to display radar chart, combined chart (bar & line). I understand that those charts are not come with APEX 4.1.0 (my APEX version). I look at AnyChart product since I see people talked in Oracle Forums. I would like to know if someone who has used AnyChart product creates radar / polar charts in APEX can give me any suggestion. My current environment is
Apex 4.1.0, oracle 11g and a browser is IE 8.
The company that I work for doesn’t have any plan to upgrade IE version. So I have limited tools to work with. On AnyChart web site, it shows radar chart in Flash, HTML5, and XML code. I can see the chart in Flash and XML code ok. I don’t know how radar chart will work in APEX and IE 8. Any helped explanation would be appreciated.

Hi jessi,
We can combine both line and bar chart in apex.
Try by doing the following,
1.Create the chart region with the chart type as 3D Column.
2.Then parse the query that you want to show in chart(it will select the series type as bar by default).
eg. select null link,ename, sal from emp; 3.Create the second series by editing the chart attributes.
4.select the series type as line. Then parse the query that you want to combine with the above bar chart.
eg. select null link,ename, avg(sal) over() avg_sal from emp; By this way we can combine the charts by adding the series,Check whether this is your requirement.

Resource Gantt Chart with Multiple Series (Apex 4.1.1)

Hi,
I am building a resource gantt and I want to show different types of entry in different colours.
My series query is:
select null,
time_record_id,
username,
null,
to_timestamp(to_char(event_date + (start_time/24),'YYYY-MM-DD HH24:MI'),'YYYY-MM-DD HH24:MI') start_date,
to_timestamp(to_char(event_date + (end_time /24),'YYYY-MM-DD HH24:MI'),'YYYY-MM-DD HH24:MI') end_date
from
oly_time_record
where
work_code = 'OFFICE'
order by 5, 3;which works well to show me the times when a user is going to be in the OFFICE.
I now want to add additional bars to the chart that shows me the times that a user is going to be 'WORKFROMHOME'.
The 'OFFICE' time should show Green bars and the 'WORKFROMHOME' should show Red Bars.
This is quite easy on normal charts, where you can add extra series but the Resource Gantt does not seem to allow more than one series.
Does anyone have any ideas about how I can get what I need?
Thanks,
Martin

Hi Martin,
there are a lot of examples of gantt charts in this forum.

Gantt chart with null dates

Hi,
Kylie discovered here that you couldn't have null dates in the project gantt query
APEX 4.0.2 Project Gantt Chart - Error Code: 2002 Message: Empty input
As Valentina suggested, 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.
As detailed in this screenshot, my red lines indicate missing from/to dates (actual data also shown underneath chart)

Steps to create Resource gantt chart with hourly ranges

Does anyone have an example of how to customize the default built APEX/Anychart resource gantt charts to handle a 12 hour range showing resources? I have tried going through a sample provided by anychart tech support, but the xml file seems to have different set of entries.
What I have is a set of rows for resources in a shop over a 12 hr shift that I need to show. I have a standard resource gannt working, but I need to customize some of the xml settings to see the date/time ranges..
Any help would be a blessing!!
Thank you,

I could post it up on Oracle's hosted site, but I am NOT seeing much help where ever it is located.. I also believe in helping up here because I can and It helps me....

Click-enable Gantt chart with Business Graphic

I know that it's possible to create a gantt char with Business Graphic. But can you tell me if it's possible to add events to the elements of the graphic?
Or maybe there are other types of object that allow this.

Creating black and white charts with patterns in Pages?

Hi. Does anyone know how to create black and white patterned charts in Pages (or other iWork application)? When making Charts in Pages (i have the most recent version), you can make all sorts of colored charts (bar charts, histograms, pie charts, etc.), but in preparing doumnets for publication i need all my charts in black & white. I can make histograms and bar charts using different shades of grey no problem, but i'd like to create histograms using black and white "patterns" like dots, horizontal lines, stripes, etc. Does anyone have any idea how to do this, or know where existing patterns can be downloaded for import into Pages?
Many thanks.

Don't export it as a .jpeg which is unsuitable for B&W images, blurring them as rgb files (not B&W).
Better is .tiff (compressed B&W tiff are tiny) or 1 bit .gif.
It is also possible that .pdf vector files might work but I haven't experimented with those.

APEX 4.0 - error building Gantt chart?

Hi everybody
When I build a Gantt chart in apex.oracle.com, start & end dates show no real dates, just the text 'dd.mm.rr'.
My query follows:
select
null as link,
description as task_name,
task_id as task_id,
null as parent_id,
start_date as actual_start,
end_date as actual_end,
progress as progress
from PENDING_TASKS;
Any ideas?
Oscar

Hi Oscar,
For Gantt charts, by default the Application Date Format will be used to format dates on your Gantt chart. If an application-level date format isn't specified and neither is a Gantt Date format, via the Chart Attributes page, then the NLS_DATE_FORMAT will be used to format dates on your Gantt chart. If you wish to define a date format via the Chart Attributes page, edit your Gantt chart, and update the "Date Format" item in the Gantt Settings region. For example, on this example on apex.oracle.com - http://apex.oracle.com/pls/apex/f?p=36648:4 - I've set the "Date Format" to *%dd.%MMM.%yy*, which uses the required AnyChart format specifiers, as outlined in AnyChart documentation, specifically in the Formatting Parameters List: http://www.anychart.com/products/anygantt/docs/users-guide/locale.html?fromtree#list.
Post-4.0 release, I did identify an issue with the popup associated with the "Date Format" item on the Chart Attributes page, and bug 9861439 can be used to track this issue. A fix for this issue will be available in our next release, but in the meantime you can enter dates into the "Date Format" text item, ensuring you use the AnyChart format specifiers outlined in the documentation I've included a link for above e.g. *%dd.%MMM.%yy*.
I hope this helps.

Hilary

SVG Multi Graph/Chart with line and bar

I have a request for a "Multi-Graph-Chart"
showing both - line chart and
- bar-chart with respective data.
Can you provide for the sourcecode, which is behind the SVG chart wizard enabling us to develop an own/individual SVG chart ?
pls kindly advise.
Bernhard
nb. I mailed u this request already - but thought this might be of interest to others as well.

Marc
I would support this addition to functionality. I currently have a client who has a requirement for complex charting in HTMLDB, and I am looking at the SVG packages in HTMLDB, ie: WWV_FLOW_SVG, but as you say they are not independent APIs and rely heaviliy on the application's metadata. This is a shame as I could quite easily handle a nice PL/SQL API that would let me create custom SVG, instead of generating the SVG manually and embedding that in the page.
Cheers
Ben
