Charts: Excel vs. HTML DB

Looking at material like
http://pubs.logicalexpressions.com/Pub0009/LPMArticle.asp?ID=390
and in general http://peltiertech.com/Excel/Charts/
one realizes that Excel's charting feature are light years ahead of anything else out there in the market. The amount of flexibility, real time feedback (previews), customization, etc Excel provides for charting is just unbelievable.
One of HTML DB's strengths is replacing the various Excel spreadsheets floating around around the enterprise by consolidating the information, it has to provide charting functionality that is at least close to what Excel provides. Unfortunately, that is not yet possible.
Reading http://www.oracle.com/technology/products/database/application_express/2006_sod.html
what are some of the "Improved charting capabilities, focusing on multi-series charts" specifically?
Wish list for pie charts:
1. Specify legend labels next to each slice with/without the associated data point
2. Fully exploded pie chart or just few slices separated.
Thanks

Thanks for responding.
I started off my wishlist in my original post.
But basically, just review the links I posted, see for yourself how Excel does it and take it from there. Excel is the (IMHO) undisputed leader as far as interactive charting is concerned, so you can't go wrong by following Excel's lead.
See, charting involves a lot of configurable options that are highly subjective and personal. People have different likes/dislikes about colors, legend positions, slices, etc, etc.
Ideally, all these should be run-time options that each user can tweak as they want. For example, the 'Show Legend' checkbox is a design-time option, that should be made a run-time option.
I realize that some things would involve a page refresh, but the goal should be to do as many of these tweaks using DHTML/CSS magic. For example
1. Show/hide legend
2. Show data labels next to each slice
3. Show data point value next to each slice
4. Change chart type (This would definitely need a page refresh!)
etc
Thanks

that chart reports to html form.

whatever the part of chart is unclean, it's totally in block colour.
what to do to present that chart part in RGB colour format on
the web. please some one help me as it is urgently required.

Here 'part of chart is unclean' means: that a report contained
two parts one is normal )in the form of data) , 2nd one is graphical
representation(pie or bar graph which is imported from graphics
builder) of that dat.
The above quoted statement means that graphical representation
part is not clear.

Please help...excel to html

Dear,
I have a assignment about java. My platform is red hat linux, jsp, tomcat server. I don't know how to upload a excel file and display this in browser. The main problem is that how to convert excel file into html format or anyother method?
that is i want to display the excel file in jsp....Can anyone help me.
Please help me as it is very urgent. please!!
Thanks very much

Work assignment or homework for school?
joycejoyce, you're swallowing a lot here if you really are fresh to Java. Have you written any Java before taking on this assignment?
You sound like you're in a panic. Get a good book on servlets, like Jason Hunter's O'Reilly book or Marty Hall's "Core Servlets and JSPs" and start reading a little before you jump into a POI black hole.
No matter how desperate you are, you can't expect anybody watching this forum to just hand you a solution. You're going to have to do some work, and it's going to take time. Start reading, coding, and learning. Try to do something easy before you do something hard. Can you run Tomcat at all? Can you do a simple servlet and JSP and get them to work? That's a start. Do that before you tackle anything else.

Save Iview as excel/word/html

Is there a neat way of exporting an iview to xls/doc/html format? It could be server side too.
So far I have explored possibilities with javascript (
shellExec
command) but this seems to work for IE only. Also when I do a SaveAs for the iview the saved file has a warning message that says 'Iview content expired....etc'.
Saving it as HTML doesnt work and it give all sorts of javascript object no defined errors.
How do I save the iview ( prefreably the same way as it looks in the browser ) to a file with the data entered.
Thanks
Sid

You could do all of this through java. You should use HSSF apis which is part of open source POI project. It is very easy to use. For more documentation and to download the jar , go to http://jakarta.apache.org
I am also planning to write a weblog on how to use HSSF api to create an excel. If you can wait couple more days, you will have a pretty good source code.
This is what code would look like.
HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    // Create a row and put some cells in it. Rows are 0 based.
    HSSFRow row = sheet.createRow((short)0);
    // Create a cell and put a value in it.
    HSSFCell cell = row.createCell((short)0);
    cell.setCellValue(1);
    // Or do it on one line.
    row.createCell((short)1).setCellValue(1.2);
    row.createCell((short)2).setCellValue("This is a string");
    row.createCell((short)3).setCellValue(true);
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();

Excel and HTML printing format in APEX 3.0 question

Hi all,
I've followed the thread Problems with PDF printing, using Apache FOP! and Carl Backstrom's instruction in this link
http://carlback.blogspot.com/ to setup print server. Just only 2 "PDF and Word" format is working and the other 2 "html and excel" don't work. When i try to use the "Excel" format to print the report, all i see is %PDF-1.3
%ª«¬
4 0 obj
<< /Type /Info
/Producer (FOP 0.20.5) >>
endobj
5 0 obj
<< /Length 795 /Filter [ /ASCII85Decode /FlateDecode ]
>>
and when i witch to "html" format and click on the link, nothing to response. Do you have any idea about it? what should i set up to use the full print features?
Thanks,
Kevin

Kevin,
Your options are to print the report as CSV and opening it in Excel (by enabling this under report attributes) or to install BI Publisher as the rendering engine. By rendering engine I mean the system that runs in the background to render your documents. So when you’re saying to print directly from the report, that’s what’s happening in the background: you report data gets posted along with a style sheet to that rendering engine, and you document gets returned so that you can download it as PDF, Word, Excel etc. Please see the following document for more details:

Interactive Report with html tags --- Data saved in Excel with html tags

Hello,
I am using APEX 4.0. I have an interactive report that displays some of the columns bold and / or colors using html tags. As an example,
SELECT
'''<font color="green"><b>'' || SERIAL_NUMBER || ''</b></font>'' SERIAL_NUMBER,'||chr(10)||
'PRODUCT_NAME,'||chr(10)||
'''<font color="teal"><b>'' || PRODUCT_DESC || ''</b></font>'' DESC,'||chr(10)||
'QUANTITY,'||chr(10)||
FROM
<Table name>
At runtime, the Interactive Report displays the fonts, colors correctly; however, when I save the data of the Interactive Report in an Excel format, it saves the Html tags along in the EXCEL spreadsheet. For example, the column serial number from the above SELECT statement is extracted in an Excel column as ---
<font color="green"><b>123456789</b></font>
Is there another way to render the column data so that extracted data will not display the HTML tags or is removing the html font color tags from the SELECT statement the only option?
Thanks in advance.
Ed

Problem viewing in Excel from HTML browser through HTTPS

Hi Everyone,
I have a small web based application, where I am displaying the data on the browser through secured connection (SSL). I have also provided the capability for the user to click on a button and view the data in an Excel spreadsheet. Basically, I am using - aResponse.setContentType("application/vnd.ms-excel") to change the content type and regenerating the html code for Excel.
Now, this works perfect when I am within the network. But when I am outside of the network, login and browse to the specific page and click on the button to view in Excel, Internet Explorer pops up a small authentication window prompting me to enter the User Id/Password again. Entering the "Id/Password" or hitting "Cancel" does not work and gives me an Excel error.
Has anyone experience this before or know of a way to resolve this? Thanks in advance for your help.
Regards,
Sadeq

Excel 2007 HTML issue losing pictures on saving.

We have an excel document that we download from a website and then save to the desktop. We then open the document and make changes then save we lose the pictures that were there previously. The strange thing is this was not an issue until we moved to office
2007 excel. We have installed the latest service packs to office and windows XP and cannot find the problem. We have tried saving in all different formats and the logos will not appear after we save the changes. Another interesting note is that if we install
office 2010 the problem goes away. Has anyone experienced an issue like this?

Hi,
Based on my research, the image may not be in a format that can be displayed in Excel. I would like to confirm the type of the image.
You can try to save the image in other types, such as JPG, and then copy it to Excel. Check again if the problem occurs.
If anything is unclear or if there is anything I can do for you, please feel free to let me know.

How to embed Labview-style charts objects into html pages?

Hello all,
I am building a C# (.Net) application that publishes html web pages. Certain pages must contain graphs that I refresh dynamically using select statement that query data from SQL SERVER databases. I like the look-and-feel of the Labview graphs and would like to know in details by which means I could embed them in my C# application. I have looked on the NI web site but aside of certain old articles about Components Works (CW) in Labview 8, have not found any other information on the subject.
Also are there alternate objects that you know on the market that would be more easily embeddable into html pages and still have the same functions as the Labview graphing objects?
Thanks a lot
Christophe

Hello Crist0phe,
Like tst mentioned it might be a good idea to have a look at Measurement Studio and evaluate it.
You can just download the trial version over here:
http://sine.ni.com/np/app/main/p/docid/nav-99/lang/nl/
FYI: You can consider Measurement Studio as the newer set of tools that replaced Component Works.
You could kind of consider it as a "next step" in evolution after Component Works.
Most .NET developers that use Measurement Studio also really like the WPF UI Controls, so for sure have a look at them while evaluating Measurement Studio.

SAP BO XCelsius : Drilldown from pie chart to raw data ( Excel Spread Sheet) in Xcelsius

Hi,
I am working on a dashboard where my requirement says, Drill down data from Pie-Chart to Raw data ( Excel Spread sheet).
Clicking on one pie should show me the required data in Excel format
May I know if this is possible to create from Dashboard design tool SAP R4
Thanks
Javeed

Hi Javeed,
Drilling data from pie charts is very much possible. The data drilled down can be shown either in spread sheet format via components called "Scorecard" "List View". But if its specified that you need the current data drilled down to a separate excel spread sheet only then, you may need to use the third party components for it.
There are many such components available for free. There are components available which are paid as well. You will have to find out which ones are free. Check out the threads below.
