Graphical/Visual representation of semantic network in webcenter

Hi Experts
As part of a solution we are developing, we require to have a graphical or link analysis view (web based) of the semantic data stored in an Oracle Database.
Ideally, we are looking for a tool/component that we can use to invoke from a portal screen.
Alternatively, are there any APIs available that we could use to develop the web based user interface/graphical viewer of the semantic data.
Would appreciate a reply at the earliest.
Thanks & Regards

Hi,
Graphical presentation of link may not realy give you whole a lot of information as to why the link is slow, graphical just provides for utilization stats and perhaps errors stats depending on the graphical software used just as prtg provided by previous poster.
One thing you may want to consider is to implementing in your router netflow and get a freeware netflow collector to see how is your link being utilized , you may need to watch the physical interface stats of your broadband link for errors to rule out physical issues in the link.

Implement Visual Representation (Stars) of user rating

I have a customer trying to implement the following visual representation of user rating.
Example
rating 1 :- *
rating 2 :- **
rating 3 :- ***
etc.
To represent the star we are using a small gif. To repeat the star as per the rating following code is attached with it under web tab
----Code--------
<?for-each@shape:xdoxslt:foreach_number($_XDOCTX,0,RATING,1)?><?shape-offset-x:(position()-1)*25?>
<?end for-each?>
This is as detialed in the
Oracle XML Publisher Report Designer's Guide
Oracle® XML Publisher
Report Designer's Guide
Release 12
Part No. B31410-01
I have checked the output and only one star is displayed regardless of the rating level.
If anybody has any further suggestions on what may be the issue here, I would be most grateful.

Hi JOhn,
thanks for the reply.
I realized IRU was useless for this, but maybe Match EQ on the before and after recorded reponses will tell us anything.
If I could dump the raw sine sweep to file (for example with wiretap pro), MatLab could also do the math. But Matlab is not free, either
I guess I'll just go for Match EQ. I'm just curious, and want some indication, don't need a thorough analysis for this.
Cheers!

Using Flash to create visual representation of Active Directory

Hi, I would like to know if anyone know how to do this? Basically, I have floorplans of the various sites that our company uses. i have made these floorplans vectors, and can be used in flash. the floor plans are quite detailed, with desks included. What I would like is some integration with Active directory, where i can have a visual picture of computers populating the various floorplans, but the population of this is driven by the active directory. so computer names and user names would be visable in this dynamic visual representation. I saw an article on the microsoft site, how to do just this with viso 2007, but wondering if i can do this with flash. any ideas?

Hi,
Yes it is possible. Basically just few things are required to go ahead
1. need to understand Flash LoadVars
2. In ASP, you need to know how to connect to and run SQL against the database
There is a thread that talks about how flash can load variables from an ASP script may help you

Thanks!
ps: please mark this thread as Answered if this is of help to you.

Creating visual representations of data

Hello World!
This is my first Java project and I'm a little bit scared. I'm hoping someone can give me a general pointer or advice on how to approach the structure and setup of this project.
I want to create a Java tool that will allow a user to input a query to a MySQL database with the result being transformed into a visual representation when returned.
An example would be a user selecting a house from a drop-down list, whereby an icon w/label representing the top 3 houses from the database would be displayed.
My questions are:
- How would I best go about setting up packages, classes and objects for this project? Just the basics, not after anyone doing the project for me!
- I would like to leave scope for scaling the icon based on relative size/weight of the results. Is this possible?
- If a user types a query instead of a drop-down list, does this have any implications from a Java perspective?
- Finally, is there any freely available code that does something similar to this already that I could refer to? Or any tutorial recommendations?
Cheers
Leon

I don't know any good resources on the web about OOD basics and software usability/ergonomy. But you might want to look at the following:
[http://en.wikipedia.org/wiki/Three_tier]
[http://en.wikipedia.org/wiki/Model-view-controller]
And use pencil and paper before writing code. Collect use cases - find out what your software is supposed to do -, and make sketches of your future GUI.

IR - reponse curves, visual representation

Hi guys,
I'd like to try out the IR utility in our video studio, before and after some acoustic dampening of the room.
What I'd like to see, is some visual representation of the room response.
Is this possible/any good with IR utility? Will the deconvolved return signal suffice as a frequency response curve for the room? What about phase response?
I have never used the utility, but just printed the user guide (42p).
Browsing it, I find no info in this regard.
Cheers + thanks for any (constructive) feedback

JDAPI: export the visual representation of Canvas to picture

I'm working on JDAPI (Forms2Java API):
and want to implementing a function to export the visual representation of Canvas to picture. Does anyone know how to do it? Please share some sample Java code or guideline of API should be used? Thanks in advance!

There is no "Render"-component in the JDAPI, so you will have to develop that "from scratch"

Hot Corners have visual representation on the screen

I don't know how I did it, but for any hot corner I have active, there is a visual representation that a corner is a hot corner. I see 1/4 of a circle in a light blue colour. If I turn hot corners off, the little 1/4 circle disappears.
Any ideas how to get rid of the 1/4 circles from the active hot corners. They never used to be there.
Thanks, B

Hi,
Thanks for your suggestions, but I don't have any of those type of programs installed. I have just got my MBP so have not installed very much at all.
Only tweak I have applied was to stop the computer waking from sleep when you open the lid, and that was done through terminal.
I am not too fussed about it, just feel like I have training wheels on

W520 graphics/visual corruption

Hi folks
So I have visual error/corruption and I'm assuming its something to do with the graphics card/s on the machine.
It appears across various applications, word, powerpoint, thunderbird, spotify, photoshop, acid pro and some others...
see these images for an example.

i seem to get random drop out on the interface of the respective piece of software at the time it is running,
it doesnt always happen and perhaps a day may go by with no problems.... but then it comes back
chunks of the interface will double-up or disappear and scrolling over often makes invisible bits reappear.
Minimizing then re-maximizing the app often refreshes it and it goes back to normal or in thundirbird saving the open email composition will bring the text back into alignment and make it all legible again....
i have updated my drivers on both the onboard graphics and the Nvidia Quadro 2000M
with no joy or luck.
i cant seem to pinpoint what it may be
any ideas anyone
or is/has anyone experienced the same problems?

Adlib:
I think you might want to do a bit more troubleshooting, to narrow down the cause of the problem, before attempting to take action to solve the problem.
Unless someone else has had prior experience with exactly this problem and can provide a 'magic bullet' solution, I think you should go into the BIOS and set the machine to run exclusively on the discrete graphics, and then see if the problem persists. Then, after sufficient experience with that modality, try setting the machine to run exclusively on integrated graphics and see if the problem persists.
If nothing else, that will allow you to narrow the problem down to one of the two graphics modes.
You might also want to consider going into the 'Power Manager' and setting the machine up as 'High Performance' to ensure that no energy-saving initiatives are muddying the waters.

Visual representations of color spaces

I copied these diagrams from the program called Color Space ...
Can be downloaded from here: COULEUR.ORG
I think that it draws spectral locus on xyY by just plotting matching x, y and Y values for every interval of monochromatic lights on the spectrum ... just like we draw the locus line in XYZ by plotting matching tristimulus values X, Y and Z.
Because the underlying data for the most saturated colors human can see is CIE XYZ color matching functions, I think that we can draw the line of spectral locus in every model originated from CIE XYZ by just making necessary transformations to the XYZ tristimulus values for the intended model.
3D representation of the entire human gamut is more tricky, I think. I will ask about it, after getting your confirmation about the spectrum locus.

A set of three numbers in xyY or XYZ defines a color.
How does it look? How can it be reproduced?
A good occasion to go back to the roots.
The CIE color system is essentially based on the work of Hermann Graßmann,
one of the greatest scientists in the 19th century [1].
Mostly his four laws are quoted [2], but it boils down to this [3]:
"The whole set of color stimuli constitutes a linear vector space,
named tristimulus space."
Colors behave like vectors in a three-dimensional space. A color is
characterized by three numbers. A fourth number would be redundant
(linearly dependent). A color is not characterized by just one spectrum. For
one color exists an arbitrary number of different spectra, called metamers.
The explanation of Graßmann's laws via spectra [4] is wrong.
Nobody knows what a color 'really' is. Acccording to the philosopher Kant,
we don't know what any object in the space 'really' is. We have just an
impression by our senses, eventually enhanced by instruments.
Colors are described by comparison with reference colors. For length and
weight we need references as well: the meter, the kilogramm.
Reference colors are (for instance) the three CIE primaries, spectral colors
with well defined wavelengths (it's not important, that the first experiments
were executed with a different set). Let's say R,G,B.
According to Graßmann one needs exactly three 'primaries'. This should
have ended a long dispute: three or four?, but it didn't.
Now we can use these spectral colors as base vectors of a coordinate system.
According to Kant, humans have an a-priori idea of space (without any proof),
where we can position objects. By intuition the axes are orthogonal.
Any other color can be described by a linear combination of the three primaries,
according to Graßmann exactly in a vector space. Color matching means:
find the three weights for the primaries to match a given (numerically unknown)
color.
Unfortunately, one needs for the matching of some colors negative weight factors,
which is possible by the concept of vector space, but somewhat disturbing for
real color mixing.
In RGB we can describe a new vector space by base vectors X,Y,Z, which form
a non-orthogonal coordinate system. All colors have non-negative coordinates X,Y,Z
and this construct has the funny feature, that luminance is identical with Y,
whereas the 'imaginary primaries' X and Z don't have luminance. Mathematically
this is not a problem.
The relation between the two spaces is given by a matrix Cxr and its Inverse:
X=(X,Y,Z)' (column vectors)
R=(R,G,B)'
X=Cxr R
R=Crx X =Cxr^-1 X
Conventionally we draw XYZ as a cartesian coordinate system (with orthogonal axes),
and R,G,B is the set of non-orthogonal base vectors – the arrangement has been swapped.
There is no natural law, which of the coordinate systems has to be shown as a cartesian.
XYZ is universal. Other RGB-systems with new primaries can be added, either as
working spaces like sRGB, aRGB or pRGB (ProPhotoRGB, which uses two non-physical
primaries, which doesn't surprise, because we got used to entirely non-physical primaries
X,Y,Z), or device RGB systems like monitor spaces. Each RGB system is related to XYZ
using a matrix, thus we can transform as well from one RGB-system to another.
Now it's possible to render a threedimensional visualization of a color space by appropriate
colors, for instance aRGB. But for a monitor these colors would be clipped almost at the
sRGB boundary.
Of course it's not possible to render pRGB correctly, because the blue and green primary
are outside the human gamut, and the red primary would be too dark. Therefore it's wise,
to use pRGB only for regions or real world colors.
There might be still an objection: the reference system contains only spectral colors.
How are the little saturated colors looking? This had been clarified by Graßmann: the vector
addition of any two colors is valid mathematically and by appearance.
These explanations may also help to end the dispute about the 'basic colors', especially
for painting. Many artists have invented their own system. The answer is simple: basic
colors are like primaries. Their location in the XYZ-space defines, which colors can be
created with positive weight factors or mixing ratios. By the way: one shouldn't worry here
about the difference between additive and subtractive color mixing.
One may have serious doubts, whether Graßmann's laws and the whole CIE colorimetry
is really valid, especially considering numerous optical illusions [5] and all these special
effects in color appearance, like Helmholtz-Kohlrausch and other nonlinearities.
It's perhaps surprising, that CIE colorimetry works so very well for image processing and
device calibration for monitors, printers and cameras.
Finally I would like to mention another scientist, which is not as popular as others,
probably because his work is mathematically difficult: Jozef B.Cohen [6].
His work has been continued by William Thornton, Michael Brill and James Worthey
(for a further search).

Graphical/Visual Input option

I know this is a long shot but... I am building an application where the user needs to indicate various parts of the body where an injury occurred. I could put the various sections into a select list (or even a series of select lists) but I was thinking it would be easier if I were to show the outline of a body and they were to click on the various sections.
Has anyone done something like this before? If so, how can it be done? Could you share the code and/or an example of a display where the user clicks on part of a graphic and a database field is updated?
Thank you in advance.

Graphical date representation

I did not find any idea how to create a component which allows to select date graphically (a kind of dialog). Is there any tutorial, component which can help me?
It would be great if this could be solved using spinner (datemodel).

I have created a few of these types of components. I always just use the Calendar class to get the date information. I use a JComboBox for the month and year and a GridLayout of JButtons for the days. It's really pretty simple.
Hope this helps,

UTF characters render automatically to their visual representation even if there is a region-specific or international rep of them. Why?

As said in the question, international characters tend to download themselves and be shown in the main text. This might be unwanted for some international users who are rather used to be shown a question mark or unknown character instead, as maybe font downloading may not be wished at all for safety reasons. This is a minor problem, and I only encountered this by seeing the "Indian Rupees" sign replaced by the hindi symbol of it, instead of the familiar "Rs." abbreviation I was used to, but still a reminder to be careful with implementing Unicode.

If you have a font that covers a specific character then you will always see the character and not a possible box with the hex code or the html entity code.

    private javax.swing.JSpinner spinnerHour;
    private javax.swing.JSpinner spinnerMinute;
    // End of variables declaration
          public static void main(String[] args)
     JOptionPane.showMessageDialog(null, new JTime(),"SpinnerDemo", JOptionPane.INFORMATION_MESSAGE);
}

I have an example of a JSpinner here which definitely works on Windows 2000, and the only difference is the amount of code.
public class MyPanel extends JPanel {
    private JSpinner spinner;
    public MyPanel() {
        super(new BorderLayout());
        spinner = new JSpinner(new SpinnerNumberModel(0,0,10,1));
        add(spinner, BorderLayout.CENTER);
}Does that work as expected? If so, then you'll have to gradually add stuff back until it does work.
