How to generate Flow Chart from Program Source Code easily and automatically.

It is very crucial to have a clear mind when faced with abstract codes for software engineers and program developers. As always, the programmers have had an overall structure in your mind and then process the design with source code. The structure can somehow be so complex that it becomes hard to cope with gradually. More often than not, you will get stuck when you process to some extent. However, codes can’t speak and present themselves in a straightforward way. You are eager to find out a straightforward layout to transfer those abstract codes to visible flowchart, aren’t you? Do you know there's code to flowchart software tools online?

Dear Chuck,
I have used Google and other search engines intensively since years. What I need (and this is why I've opened this thread actually) is a suggestion for a product from someone that has already used it. That could also save me time instead of searching, installing, trying, and eventually deinstalling at random. After all, the forum should allow to exchange knowledge and experience with people having similar interests.

How to generate line chart (e.g. stock market) in midlet?

how to write such a line chart in midlet? any tutorial recommended?
thanks a lot.

Well, I would draw it myself. I think that's your only option. If you are not familiar with MIDP, then you should start with a beginner tutorial - it will not have anything to do with graphics, but more importantly it will introduce you to the programming model. You'll need the experience when you grapple with graphics. Not a big deal, but I haven't seen any samples for it, so you'll have to work off of the API docs. A nice page with sample programs:
http://wireless.java.sun.com/midp/samples/
If you are familiar with MIDP programming, or when you are, then hop over to the API and you'll find what you need there. Some simple math and some custom graphic routines/classes and you'll be well on your way. Here's the API location for the graphics class in the MIDP API:
java.lang.Object
|
--javax.microedition.lcdui.Graphics
Good luck. Hope this helped.

How to generate control limits in control chart

I want to generate a X bar chart with control limits, sample size is Fix- 1.
SPC criterion I selected is 020 ie Task List characteristics/ Material.
1)Sampling Procedure I used- Fixed-1
2)Valuation mode I used- Attrib non conforming units/ manual.
3)Control chart I am using is 110- Shewart chart for X bar.
But when I click for control limits in chart it is saying control limits for track 1 could not be calculated.
Could anyone guide me, how to generate control limits for this graph. Sammple size will alwyas be 1.
Please let me know should I change control chart type in this case.

Hi Jaison,
You should use valuation mode - SPC valuation in sampling procedure.
Also you have to use sampling procedure with inspection points.
as practically every hour or depending on the frequency decided we collect the measurements and calculate the SPC.
now after correction in the sampling procedure create new inspection lot and check SPC.
try out and revert.

Anil

How to Generate Statistic Graph in Report??

Hi, i am developing an questionnaire program together with 19 question... i am able to get value for each value..
Now my problem is how to generate a statistic graph whenever user can check their report ??
Can anyone help?? Thank you very much......
from bscs

The easy way is to use your values to set the width or height of an image dynamically in HTML, but you can only do bar charts using this method.
For real reports and measures have a look at

Is there any way to generate Gantt chart by using oracle 9iDS?

Is there any way to generate Gantt chart by using oracle 9i reports builder
Can you please send me the link or more information on oracle 9iDS.
Thanks

Hi,
Oracle9iDS itself doesn't support creating Gantt charts. The option oyu have is to use Oracle Graphics 6i, because there is no Graphics in 9i, and configure it to run with Oracle9i Forms. There exist a whitepaper at otn.oracle.com/products/forms that explains how to make Graphics 6i work with Forms 9i.

How to Generate and Display SVG Graphics in ABAP

Hi everybody,
I tried to complete the Tutorial "How to Generate and Display SVG Graphics in ABAP, Part 1" by Siarhei Ulasenka (https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/ad83a990-0201-0010-d680-a189f8bc20fa).
Unfortunately when I tried the example to display an SVG Drawing in an ABAP Report I get the error message "Es ist ein Laufzeitfehler aufgetreten, ungültiges Zeichen" (english should be something like "Runtime Error, unkown character"). But it works when I open the svgfile in a new IE Window (parameter in_place from cl_gui_html_viewer->show_url). Also when I open a svg file from the local disc it works fine.
The code:
    CALL METHOD html_control->load_data
      EXPORTING
        url            = 'chart.svg'
        type         = 'image'
        subtype    = 'svg+xml'
      CHANGING
        data_table = lt_svg
      EXCEPTIONS
        OTHERS     = 1.
    CALL METHOD html_control->show_url
      EXPORTING
        url        = 'chart.svg'
        in_place   = 'X'
      EXCEPTIONS
        cntl_error = 1.
Has anyone a solution? Thanks in advance for your help!

Hello Alex,
The Corel SVG viewer has problems loading and displaying the examples (see the list of limitations at their site). Try to use the Adobe viewer instead.

CHART BUILDER ERROR WHEN TRYING TO GENERATE DYNAMIC CHARTS ON A JSP PAGE

I'm working with J Develop 9.03 on Windows 2000 Professional Edition.
I'm using the JSP demo files provided with Oracle Chart Builder to generate
dynamic charts. The user specifies the query parameters, including the date
range and the query results are returned by means of a line chart (with date on
the x axis and values on the y axis).
When trying to compile the project I get the following error messages:
Error(165,2): class FileOutputStream not found in class _graph
Error(170,5): class File not found in class _graph
Error(176,4): exception java.io.IOException is never thrown in the
corresponding try block
I checked to see that the chartbuilder library (chartbuilder.jar) files are
loaded into the project library. It's unusual that the class is not being
found. I don't understand why. I developed my project using the following steps:
1. Unzipped Chart Builder installation files into c:\Oraclechartbuilder
2. Loaded chartbuilder class library
c:\Oraclechartbuilder\chartbuilder\lib\chartbuilder.jar into J Developer class
path (by selecting <Project Settings> <Paths> and browsing to the
chartbuilder.jar file).
3. Created a new JSP page in J Developer (graph.jsp)
4. Copied JSP code syntax from the Word Pad demo file and pasted into graph.jsp
5. Changed the DB connection parameters and static directory location on the
JSP page.
6. Compiled the project and received the above errors.
I would like to know why the classes are not being found and how to fix the problem. Thanks, Jaafar

Hi mshah101,
This can happen if the applet is compiled using an higher version of java and the browser is pointing to an older version (even if minor version number is higher)

JFreeChart - You can generate the charts then convert them to image formats (PNG and JPEG) all using the JFreeChart API
http://www.jfree.org/jfreechart/

Generate report chart files.

Hi All:
Will AE do automated generation of charts (bar) into GIF or JPEG? Is there any Oracle product that will do this, besides Chart Builder?
I would like to use Chart Builder but it is not a supported tool any more, it was a beta. Please advise.
Regards,
antonnon

if I should not modify the query, how to generate the graph many times? If you are using the following query, you can pass the parameter to run for one customer or for all customers:
select name,location,sal,departement from table1 t1 and table2 t2 where Number1 = Number2 and sal < 20000 and Number1 = '100'; So modified query will look like this (see the part in bold):
select name,location,sal,department from table1 t1 and table2 t2 where Number1 = Number2 and sal < 20000 and *(:p_customer_no is null or Number1 = :p_customer_no)*
Hope this helps.

Oracle form 6.0, how to do 3D chart, calender,mouser over changing....

The cpu resources are only limited once the cpu's are 100% utilized. It is highly unlikely that dom0 will try to use 100% of a cpu, let alone all cpus. Only when there are no idle physical cpus would you run into issues.
You may want to try reducing the number of vcpus in the windows guest. I have seen reports from users claiming that having more vcpus in a windows guest causes it to run slower.

Any help would be highly appreciated. Thanks in advance

Hi ,
One 'simple' way is by using the DBMS_SCHEDULER db package and the procedure CREATE_JOB(....) using as job_type the value 'EXECUTABLE'...
Read for further info in 'PL/SQL Packages and Types Reference'.
If you have access to OEM ... you can configure this there using wizard.....
Other way is to use the External Procedure call capabiblity of Oracle DB Server...:
