Need EXPERT's suggestion for APEX CHART SERIES

Hello Everyone,
I have been trying to solve an issue with my apex line chart. The scenario is as follows:
I 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.
I hope I make sense and anybody can suggest something.
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. ... ?

Samooray,
Let's work with this question since there is more detail here than in the other one. {thread:id=2543702}
First it's always help to know:
Full APEX version
Full DB/version/edition/host OS
Web server architecture (EPG, OHS or APEX listener/host OS)
Browser(s) and version(s) used
And sometimes this information as well.
Theme
Template(s)
Region/item type(s)
When a question goes unanswered for a while, there is no need to reply to it or to start a new question. You can edit the original question and just add "Bump" at the bottom and save the changes. This will bump it back to the top of the question list. And by that time, you might think of additional information you can add to the question.
Say, why would a question go unanswered? Well, easy questions and frequently asked questions with well-known answers can be answered right away. Your question seems more complicated and I don't think we have all the information we need to understand exactly what the question is.
You are doing a "series" chart. What kind of series chart: bar, column, line? What is each series? For example, components of revenue might be 1) sales, 2) licensing revenue and 3) other. Then you might have one series for sales, a second for licensing revenue and a third for other.
Could you mock up a trivial example on apex.oracle.com http://apex.oracle.com/pls/apex/f?p=4700:1:0::::: ?
Regards,
Howard

How to set the (specific) color for a Chart Series in a Flash Diagramm

Hello all,
I wonder how I can set the color (of a bar) for a Chart Series in a Flash Diagramm.
So far I found now set-screw for this.
Can someone give me a hint please.
Thanks in advance.
Andre

Hi,
On the Chart Attributes page for the region, change the "Color Scheme" setting to Custom. Then, in the "Custom Colors" setting, enter the colours you want for all series, separated by a comma. For example:
red,yellow,greenAndy

How do I set default colors for XY chart series (lines and legend)

I am implementing a line chart and need to override the default (caspian style) colors for the line colors and the legend symbols. I'm not displaying the chart symbols themselves as that would make the chart look bad. I've been able to successfully set the default colors for the lines via the CSS below, but cannot find a way to do the same for the series symbols that appear in the chart legend. How do I do this? Thanks.
.default-color0.chart-series-line {
-fx-stroke: rgb(0, 102, 255);
.default-color1.chart-series-line {
-fx-stroke: rgb(0, 255, 102);
...Update:
Figured it out. Need to do the following:
.default-color0.chart-line-symbol {
-fx-background-color: rgb(R, G, B);
}Edited by: 998038 on May 16, 2013 4:09 PM

Here is some css to customize the line and legend colors in a line chart.
/** file: chart.css
    place in same directory as LineChartWithCustomColors.java */
.default-color0.chart-series-line {
-fx-stroke: rgb(0, 102, 255);
.default-color1.chart-series-line {
-fx-stroke: rgb(0, 255, 102);
.default-color0.chart-line-symbol {
-fx-background-color: rgb(0, 102, 255), white;
.default-color1.chart-line-symbol {
-fx-background-color: rgb(0, 255, 102), white;

Needed Varible ND Suggestions For 7d EFS 17-55mm Lens

Hi, I'm looking for suggestions for a varible ND filter for my 7D EFS 17-55mm lens. Wanting to shoot video on the high end towards the f/2.8 range of this lens. Currently, my sweet spot without a ND is anywhere from f/14 to f/18 bright/cloudy outdoors. I normally shoot at 1920x1080 at 24fps with my shutter speed at 1/50. As you know, the higher the aperture the brighter things get. At f/2.8 I'm totally washed out. I have a B+W UV XS-Pro filter that currently lives on the lens https://www.schneideroptics.com/Ecommerce/CatalogItemDetail.aspx?CID=1554&IID=8160
I see Light Craft Workshop has come out with a Rapid Variable ND lately that looks interesting. http://www.bhphotovideo.com/bnh/controller/home?O=&sku=1015993&Q=&is=REG&A=details
If you have any suggestions that would give me great results, I would sincerely appreciate it. Thanks, Ray

Personally I'd get a standard ND filter instead of a variable. Looks like 5 stop is what you need. I know B+W makes a 6 stop, you might be able to get that to work.
Perhaps variable NDs work well with video. When I looked into getting one for stills it seemed to me it just wasn't worth it if you're picky about your quality. Anything less than the SR was of dubious quality and even the SR had problems with the X banding at higher opacities. With stills you usually have some wiggle room over settings so having a 3 stop and a 6 stop, and stacked for 9 stop, was enough for my needs.

Suggestion for the chart

Hi,
Can anyone suggest a relevant chart for this in ADF
http://s7.postimage.org/wzb85f3xn/chart.png
Thanks,
Vinod

Hi Timo,
Thanks for sharing the info. Great information there. but not helpful in this case. :(
Actually the customer is not happy with the Guage or status bar or anything that is normally provided with dvt components.
They have come up with the screenshot which is hard to find in ADF DVT.
Couldn't find similar charts in opensourcecharts or other javascript charts, which made me to post it here to get some inputs from others.
Thanks,
Vinod

Need new PC - Suggestions for system requirements needed!

Hello!
I am taking a class in CS4 Design Premium and will be purchasing the software as soon as I buy a new computer. I've been looking into an Acer or HP Desktop PC (<$700) with the following minimum requirements:
4GB RAM
2.0GHz processing speed
500GB hard drive
I've read the Sticky posted on this site regarding graphics cards compatible with CS4, but I'd really appreciate suggestions from the users. What do you feel is the best system to purchase for a new web designer? Are there other components I should be concerned about?
I truly appreciate any and all input

Need Expert's Suggestion

I am working in IT concern for past 2 years. I have the knowledge in Core JAVA,J2EE(Jsp,Servlet), SQL and UNIX. I feel this knowledge is not enough to become Technically strong guy. My objective is to become an Technical Architect. I need advice from the experts that, What are the technologies in Java should be known to enhance our career as well as Design perspective. kindly suggest me some thing which need to be learn to acheive my objective. Also forward some useful materials to my email id if like to share it with me.
My email id is : [email protected]

The role of Technical Architect differs from company to company, I'm not sure there is a definative description of the role.
In general, I would say a Technical Archtect must have the following critical experience;
- At least 7 years developer experience, including 2 years as lead developer. This experience should cover several languages.
- A strong understanding of associated technologies relevant to their role, eg web servers, application servers, databases etc.
- The ability to keep up to date with new developments in technology, and to critically analyse products and technology and report to their peers, superiors and other interested parties.
- A strong understanding of theory, best/accepted practice and standards relevant to their role.
- The discipline to give advice and take advice and objective criticism, and to not overstep the remit of an architect (for example telling developers how to do their job).
I think it takes a certain kind of character to become an architect, with 2 years dev experience you probably shouldn't be making career plans like that just yet. The fact that you don't know what you need to know to be a Tech Architect means that you shouldn't be planning on being one.

Need help with SQL for Pie Chart

I am trying to create a pie charge which would have 3 slices.
Following sql gives me the expected values when I run the sql command:
select
round(avg(CATEGORY_1 + CATEGORY_2 + CATEGORY_3 + CATEGORY_4 + CATEGORY_5),0) "OD Engagements",
round(avg(CATEGORY_6 + CATEGORY_7 + CATEGORY_13),0) "Talent Engagements",
round(avg(CATEGORY_8 + CATEGORY_9 + CATEGORY_10 + CATEGORY_11 + CATEGORY_12),0) "Other Engagements"
from OTD_PROJECT
where STATUS in ('Open','Hold')
I get 3 columns labeled: OD Engagements, Talent Engagements and Other Engagements with the correct averages based on the the data.
I have tried several ways to try to get this to work in the SQL for a pie chart, but keep getting the invalid sql message and it won't save. I also tried saving without validation, but no data is shown on the chart at all.
I want to have a pie, with 3 slices, one labeled OD Engagements with a value of 27, one labeled Talent Engagements with a value of 43 and one labeled Other Engagements with a value of 30. Then I want to be able to click on each pie slice to drill down to a secondary pie chart that shows the breakdown based on the categories included in that type.
Since I am not grouping based on an existing field I an unsure what the link and label values should be in the chart sql.

You'll need something like the below. I have no idea what the URL for the drilldown needs to be. It should create an appropriate link in your app for the particular slice. Mainly the code below breaks the SQL results into three rows rather than three columns. It may well have a syntax error since I can't test.
select linkval AS LINK,
       title    AS LABEL,
       calc_val AS VALUE
FROM   (SELECT 'OD Engagements' AS title,
               round(avg(CATEGORY_1 + CATEGORY_2 + CATEGORY_3 + CATEGORY_4 + CATEGORY_5),0) AS calc_val,
               'f?p=???:???:' || v('APP_SESSION') || '::NO:?' AS LINKVAL
        from   OTD_PROJECT
        where STATUS in ('Open','Hold')
        UNION ALL
        SELECT 'Talent Engagements' AS title,
               round(avg(CATEGORY_6 + CATEGORY_7 + CATEGORY_13),0) AS calc_val,
               'f?p=???:???:' || v('APP_SESSION') || '::NO:?' AS LINKVAL
        from   OTD_PROJECT
        where STATUS in ('Open','Hold')
        UNION ALL
        SELECT 'Other Engagements' AS title,
               round(avg(CATEGORY_8 + CATEGORY_9 + CATEGORY_10 + CATEGORY_11 + CATEGORY_12),0) AS calc_val,
               'f?p=???:???:' || v('APP_SESSION') || '::NO:?' AS LINKVAL
        from   OTD_PROJECT
        where STATUS in ('Open','Hold')
       );

Suggestion for APEX/HTMLDB FAQ

Hi!
Have/would you consider searching this forum for the posts that are most referenced from other posts and pulling out the answers and examples and putting them into the FAQ? Of course you should give the credit to the folks who posted the answers! I have noticed that same questions get asked alot and often the answer is a reference to another forum posting or thread. These seem to be the best practice and most usefull answers. Also alot of very good technical info is found in these referenced threads.
Just an idea. What do the rest of you think about this?
Dave Venus

Hello,
I think it's a great idea. There is a FAQ section on the APEX wiki hosted on shellprompt.net.
http://wiki.shellprompt.net/bin/view/Apex/FaqCategory
It might be a bit nicer to have it hosted there as it's a bit easier for the community to keep the information updated.

New suggestion for APEX Poll

I wondered what type of people are using APEX?
- DBA
- Developer
- Between the two; DBA4DEV
- End-user
- Manager
- Other
Maybe this is a good question for the next poll?
I see myself as a DBA4DEV.

I would clearly consider myself a professional Oracle developer, with a strong focus on web applications. I did a lot of Oracle Portal stuff, too.

Need 3D data / dimensions for Curve 8300 series

I am a product designer working on a new Curve 8300-series case for a client. I have been trying to track down the technical dimensions of this model, but so far, no luck!
Can anyone help me with either the 3D-data, 2D-scaled dimensioned drawings, or good place to go look? I've tried everywhere.
Thanks, Dave

I'm not sure if this information is readily available. The best place to start is by contacting RIM to see if they will release this information to you: http://www.rim.com/company/contact/index.shtml
Alternatively you could do your own measurements if you have a model available (not easy measuring all the intricate dimensions, but that depends on the tolerances and fit you are aiming to achieve.

Need the career suggestion for Java developer

Dear all,
I am a programmer with four years experience in webMethods integration. I am also good at Oracle PL/SQL, XML and Java.
So, here is my question, shall I study for an ABAP certification and begin to look for an ABAP job? or, based on my background, I should try to get a Netweaver Java Certification and try to move to portal development or SAP XI?
Regards,
Mike

hi mike,
Its good u have such a good experience in webmethods and oracle/pl-sql and also java. i feel abap would be much better option to move on to.
ABAP is sap custom language, and it would always be preferred more over everthing else, and apart from that certified abapers are still very few, while compare that with java, which is at peak in the job market,and flodded with java proffesionals.
And as u have previous experience getting through abap certification wont be tough.Happy abap programing.......!!!!
Best of luck
