Need to change colors of lines in an Omniportlet Line Chart

I am running Oracle Portal on a 10g Web server. I have created an Omniportlet and I am displaying data in a line chart. Is it possible for me to define the colours of the lines in the linechart?

Hi I didn't changed colors in line chart but I managed to redesign lot of omniportlets.
What you can do is to re-define CSS.
Add an HTML portlet in your page with some CSS embedded.
To catch wich class are to be re defined, I recommand you to use firefox with the extension Webdevelopper.
Use the "Informations - display element information" functionnality to catch wich class are used for your chart.
Then redefine those classes in your custom CSS.
Hope that will help

CS4: Change color of line indicator/outline tool (not line itself)

I couldn't find an answer in any of the resources - possibly because I don't know the right term.
I am talking about the line that is displayed during the period that you draw a line - from the time you click the mouse, until you release it. There's a thin greyscale line indicating the outline of the item you are drawing.
I'm working on ultrasound images, full of greyscale spots. In order to draw lines as precisely as possible, I would prefer that the outline that is displayed while I'm trying to draw my line as correctly as possible, has another color.
I know how to change the color of lines that I have drawn, that are part of the image. What I need is to change the color of the line indicator/helper tool that ONLY shows WHEN I'm drawing a line, and is not really a part of the image.
Hope you can help!

It's a well-known shortcoming that the path that's drawn with the pen is hard to see under some circumstances.
One thing: Its appearance is a little different with OpenGL Drawing disabled vs. enabled. What's your setting (Edit - Preferences - Performance)?
If you're not in need of the OpenGL features, disabling OpenGL Drawing could be helpful in making your paths somewhat more visible. Such a change is not without downsides, but perhaps it could serve as a workaround for you.

Need to change color of template

I directed a client to a template site and they picked a template that was a PSD (attached) and I turned it into a working website. Now they tell me they want it to be blue instead of the green that it is. I am not sure where to start. I guess I need go to each layer and change the color to a variation of blue. Is there a quick way to do this? I am not even sure how to change colors. Any help would be greatly appreciated.
Thanks!

You do not need to do this for each layer. Just the ones with the color elements of the webpage,and only those that are visible. (eyeball on in layers panel)
When you select the layer,then you go to the Image menu,Adjustments,and select Variations. You can interactively experiment until you find what's best.
My layer thumbnails are large so I can see at a glance what element I'm looking at. Use the Layers Panel menu to get to Panel Options and select Large Thumbnails.
Of course back up that template before loading into PS in case you need to do it over.
That should get you started.

Autopacman.
Maak via overerving van de klasse Packman uit week 4 een nieuwe klasse 'AutoPackman'.
Deze klasse moet de volgende extra functionaliteit bevatten.
De kleur van de Packman moet kunnen worden ingesteld.
Er moet een methode komen die een willekeurige opdracht aan de Packman geeft.
(naarLinks, naarRechts, gaSneller, gaTrager, etc.)
Maak vervolgens een applet met vier Packmannetjes en ��n knop 'Beweeg'.
Als je op deze knop drukt, moeten alle Packmannetjes ��n stap in een willekeurige
richting doen.
Programmeer dit efficient met arrays en loops.
Als je na afloop nog moed hebt kun je de klasse en de applet zo aanpassen dat een
spel ontstaat, waarbij een Packman die op de positie van een andere komt, de andere
Packman opeet. Degene die overblijft heeft gewonnen.

Need help changing colors in a photo.

I am trying to help some artists in mexico with their weaving. We are using elements 11 on vista 7. We would like to change colors in a piece to see if they are pleasing to the eye. Is it possible to change colors thoughout the whole piece at once? Using a brush to paint over each and every area would be so time consuming as their work is quite intricate. If this is not possible on Elements does Adobe have another sotware that would accomplish this task. Thank you for your time.

I did not know I had to go to expert as i have never used this type of program before.The help was just telling me the tools were on the left side. I thank you for pointing me in the right direction. I have a feeling it will be easier for me to learn Chinese.

Chart backdrop showing exceptions with colors with line chart on top of it.

Hi, I have the follwoing to create a query and the associated chart.
good 90-100, fair 70-90, poor 0-70
While I can get the chart without any issue, the customer demands the backdrop of the chart has to be
painted with red, yellow and green colors as above ratings and a line chart then be drawn over it showing all other data, 90.2 75.1, 60.9, 82.5.....you guys get what I am saying.
Is that possible in any of the SAP query BI tools, can you all suggest something, any other ideas.
Thanks.

hi,
you can create exceptions which automatically shows result in 3 colors

How do I change legends in line charts when you change line type

I have created a line chart with two lines. I only have a black and white printer. If I change the two lines to black, the legends change to match. To distinquish the two lines I change the line type making one dots and the other dashes. The lines change but the lengends don't. This makes the graph useless.
Any suggestions on how to get the lines in the legends to change to match the lines in the graph?
Thanks for any help.
Paul

I could not get the line legends to differ either. You can add a marker to only 1 of the plots though:

*2. It is grouped*
+Menu > Arrange > Ungroup ( option shift command g)+
*3. It is a scan or pdf*

Need to change color of a symbol with a custom slider

I'm pretty new to Flash and am not sure if it is the right app to try to do the following:
I need to create an interactive piece. It's much more involved than this but fundamentally I need to create a slider on the left side of a window that is the color spectrum. I'll put a small triangular pointer beside it that can be moved up and down beside the spectrum. I want whatever color the slider is next to to show up in a symbol on the right. I've attached a simple image that illustrates it.
So to restate it again, I'd slide the triangular symbol up and down beside the spectrum gradient on the left and whatever color it is pointing to would just show up in the symbol on the right, real time.
Is this possible in Flash and if so I'd appreciate some guidance about how to start coding it? I'm not a programmer but do know and understand how code works fundamentally. I understand that Flash uses Action Script and I assume that with Action Script it's most likely possible to do this.
Thanks,
Rob

Changing color of lines that identify selected objects

Some of my artboards use the color yellow to highlight selected objects. Can I change that?

that would be your layer color. in the layers panel double click on the layer to get the options window and change the color there.

Change color and line weight

Hi,
I am trying to create a script who could act as an Autocad plot (ie convert each color to black, with a different lineweight). I did some research, and tried to mix some scripts found here to create my own, but there is a lot of things I don't understand yet… If anyone could give an eye at these, it would be great!
Here is the first script I melted, who create my Black swatch
if ( app.documents.length > 0 ) {
var myDoc = app.activeDocument;
//add Black swatch
var newSwatch = app.activeDocument.swatches.add()
var newColor = new GrayColor();
newColor.gray = 100;
newSwatch.name = "Black"
newSwatch.color = newColor
//Sélectionner les lignes par spot color
var findColor = swatch.getByName("AutoCAD Color 2").color;
var replaceColor = swatch.getByName("Black").color;
//pathItem.strokeColor
var idoc = app.activeDocument;
var itext = idoc.textFrames[0];
//alert(itext.textRange.characterAttributes.fillColor);
var fillColor = itext.textRange.characterAttributes.fillColor;
var strokeColor = itext.textRange.characterAttributes.strokeColor;
filled = stroked = "yes";
if (fillColor=="[NoColor]")
        filled = "No";
if (strokeColor=="[NoColor]")
        stroked = "No";
alert("Filled: " + filled + "\n" + "Stroked: " + stroked);
And here is the second one, who replace one color by Black (it don't change the text, nor the lineweight yet…
if ( app.documents.length > 0 ) {
//test de dialogue
function csDialog() {
     var fabGroup = app.activeDocument.swatchGroups.getByName('Fabrics');
     var allFabs = fabGroup.getAllSwatches();

When I change the color though the new tables added do not take the new color of the initialize event.

Photoshop CS 5 need help changing color from yellow to red

Trying to change the background image of a webpage in photoshop CS 5.
Can someone tutor me on the proper way to change the yellow on this graphic to the following RGB
R153
G11
B25
Thanks!

Many options …
In this case I would recommend to
• select green channel (command-click it)
• create a Solod Color Layer of the intended color
• go into the Layer Mask (alt-click it in the Layers Panel) and use Image > Adjustments > Curves and hit Auto to get the brightest Pixels to white
• use the Burn Tool set to Shadows to get the lower part to black (which corresponds to transparent)
• create a black Solid Color Layer underneath that
Other options would be a Hue Saturation Layer set to Yellows, a Solid Color Layer set to Blend Mode Color and with a Layer Mask etc.

Need to change colors of lines in an Omniportlet Line Chart
