Hiding and displaying cfcharts

I use cfchart a lot - flash charts from queries - and think
it's great. The problem is that it is so great I want to display
more charts for users.
I don't want my web pages to get too long and I don't want
users to have to click links to other pages to see additional
charts. I've seen websites that let you click on links (or better
yet, tabs) and other charts pop up replacing the chart that was
there.
Is there a way to do this in coldfusion wth cfcharts?
Thanks,
Mike

TestStand I am still learning, but LabVIEW I know. There are several things that you could do. One thing would be a splash screen. I don't think that this is what you are after, though.
Each control has a terminal on the block diagram. If you right click on the terminal, you can create a property node. There are lots of properties that you can set on a control, including whether it is visible or greyed out. I think you want to hide the controls and SAVE the VI that way. Then, when the VI is run, where the control/indicator gets its data, set it to visible with the property node as well. If this is in a subVI, you might need to create a reference to the control/indicator and pass that into the VI as well. You can then wire it to a property node in the subVI.
There are several examples on using property nodes that ship with LabVIEW that should be able to get you started.
Hope that this helps,

Hiding and Displaying TS UI Controls from LabView

We have a custom TestStand User Interface, written in LabView, that is a modified 'Simple' User Interface as installed with TestStand.
When our UI is initialising the TestStand UI controls are immediately displayed with nothing displayed inside them, this looks very untidy. Is there a way of hiding and displaying TS UI controls on demand?
Regards
Steve

There are 10 types of people in the world that understand binary, those that do and those that don't.

Hiding and displaying the tab

Hi Every body :
In my application I have 4 tabs and I want to know how I can hide the tab according to the user previllige, if he has the privillage then the tab will be visible and if he doesn't it shold be hided...
Thanx in advance

JTabbedPane itself uses the visibility of the children to control which one is shown and, of course, draws the tabs itself. There is no way to hide a tab, just don't add the child in the first place.

Supress Subtotal rows and display overall result of keyfigure

Hello there,
Is there a procedure to hide result of a keyfigure at subtotal level and display result at overall result level?
Please let me know.
Points assured.
regards
Joga

Hi Daya,
Thanks for the reply. in the report i have other keyfigures also for which i need to show subtotals.
its only for 3 keyfigures i need to hide the subtotal result and show overall result.
when iam hiding the result rows of the key figure iam not getting the result in the overall result column as well.
i only want a result for overall result while supressing the subtotals for 3 keyfigures out of 10 keyfigures.

Calculating and displaying the Length of the side of a triangle

Hi everyone. I am currently working on Dragging and Stretching a triangle on screen. Ive got it working to a certain extent but the only problem is that whenever I go to the point from which i have to drag my triangle i.e. the Left hand Corner of the BAse at exactly 300,300 it redraws a new triangle below the existing one and then when i stretch it from the top and the right it leaves a trail of triangles everytime. But when i resize my window it clears the trail only to start agian when I drag or stretch it...
All my code for wahtever I have done is displayed below. I would appreciate all the help that any one can offer.
Secondly , as I stretch my triangle I would like to calculate My Length of the hypotenuse and the other 2 sides as they change and display it in System.out.println for now...
PLEASE HELP

Hey sorry mate.. ive got a nother problem.
I need to add loads of theorems to this tool. so i need a JMenu Bar called File with all the normal things. then another Menu called Theorems where i can have a list of JMenuItems with the theorem names --- Like when they click on Pythagoras Theorem it opens up all the triangle and the traingle data that u helped me with.
The thing is im using netbeans and in netbeans i can do it coz its there and all you got to do is put the components together.
Please Help

Help, how to open and display blobs from tables

Dear all,
I am trying to store ms-word files on a table using a blob column.
Does anyone how to open the files and display them from a form using 9iAS?
Thank you.
Carlos.

And there may be, but you won't likely find that here. Do some time searching Google and maybe you'll find code that someone was nice enough to make freely available, although I wouldn't count on it. Were i a programmer and took the time to read those docs and write the code, I'd want to be paid for my time. But there are a lot of programmers who swear by freeware! You may get lucky.

Hello!
I cant figure out how I shall do this in an MVC layout:
The program request user to open an image file that are then displayed in a JLabel
My setup at the moment resolve in a nullpointerexeption because it dont get any actual image file, but I dont understand what I have missed.
I can not post the whole code fo you to run because it is to big, so I post the part that are the most important. please have a look.

Dear Friends,
Please provide the solution for the following scenario:
In the first view(xml) I have a table with the fields QuotationNo,plant name, material no...etc, where I am displaying the data fetched using Odata model. The table is enable with Single line selection mode. My requirement is to Carry the selected row data to another view(xml) and display there.
Please give your valuable inputs.

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

Refresh table and display the records after insertion of data from back end

Hi Experts,
JDEV 11.1.2.1
I have a useacase which needs data to be inserted from oracle back end procedure and displayed in a ADF Table Component, when a button is pressed.
is this possible?..if yes , how?
Is view object will automatically refreshed and fetches newly created(from back end) rows?
thankz in advance
PMS

Hi user707,
thankz for ur reply....
i think after executing a procedure you want to call commit operation. better you can perform this.getDbtransaction().commit In Application Module;yes i want to commit transaction after executing back end procedure using preparedStatement.Procedure is for inserting data into same table , which used for creating VO and Read only ADF Table.Procedure is executed fine, but newly created records are not getting into ADF table.Once i did commit opeartion inside back end procedure, whole records are getting into ADF Table.
Is there any way to get whole records without doing Commit operation inside Back end procedure?

Reading XML file into Dynamic Node and Display its output as Table.

Hi All,
Following is the output of XML file:
   <Company>
     <Employee>
          <Name>John</Name>
          <Age>23</Age>
          <***>Male</***>
          <Location>Frankfurt</Location>
     </Employee>
     <Employee>
          <Name>Tina</Name>
          <Age>21</Age>
          <***>Female</***>
          <Location>Boston</Location>
     </Employee>
     <Department>
          <Name>Sales</Name>
          <HQ>Chicago</HQ>
          <Emplyoees>2300</Employees>
     </Department>
I'm able to read the output through DOM parser. But How do I convert this into dynamic node and display this in Web dynpro as Table?
Any pointers in this regard will be great help?
Thanks

Hi Maksim,
I've used your example and its now helping as there is kind of agreement on that I'll be knowing the structure of Xml and I can fill the nodes.
But suppose if you have Xml has following structure :
<?xml version="1.0" encoding="utf-8"?><DATA>
<item><MAILERID TYPE="C" SIZE="000030">21</MAILERID><ORG_CODE TYPE="C" SIZE="000004">1232</ORG_CODE><EVENTID TYPE="C" SIZE="000015">CONTRACT</EVENTID><SUBSCR_VALUE TYPE="C" SIZE="000001">0</SUBSCR_VALUE></item>
<item><MAILERID TYPE="C" SIZE="000030">21</MAILERID><ORG_CODE TYPE="C" SIZE="000004">1232</ORG_CODE><EVENTID TYPE="C" SIZE="000015">CREDIT</EVENTID><SUBSCR_VALUE TYPE="C" SIZE="000001">0</SUBSCR_VALUE></item>
<item><MAILERID TYPE="C" SIZE="000030">21</MAILERID><ORG_CODE TYPE="C" SIZE="000004">1232</ORG_CODE><EVENTID TYPE="C" SIZE="000015">EMPRESS</EVENTID><SUBSCR_VALUE TYPE="C" SIZE="000001">0</SUBSCR_VALUE></item>
<item><MAILERID TYPE="C" SIZE="000030">21</MAILERID><ORG_CODE TYPE="C" SIZE="000004">1232</ORG_CODE><EVENTID TYPE="C" SIZE="000015">PAYMENT</EVENTID><SUBSCR_VALUE TYPE="C" SIZE="000001">0</SUBSCR_VALUE></item>
<item><MAILERID TYPE="C" SIZE="000030">21</MAILERID><ORG_CODE TYPE="C" SIZE="000004">1232</ORG_CODE><EVENTID TYPE="C" SIZE="000015">PRICE</EVENTID><SUBSCR_VALUE TYPE="C" SIZE="000001">0</SUBSCR_VALUE></item>
</DATA>
How we will do in this case?
Can we have something similar using DOM? Also what is the best method for displaying data being sent in form of XML. And generalize it for cases like this.
Thanks

How to wrap text in two columns and display as one in WAD

Hi ,
I have the following columns in my ODS , they are not KF's
c1        c2    c3
100      AA      BB
200      CC      DD
I need this display format
100   AA
      BB
200   CC
      DD
I need to wrap the text in columns c2 and c3 and display them under one column.
Is it possible in webtemplate by using java scripting.

IN the Query , you could diplay Characteristics as a Hierarchy. Just above the Columns Box in Bex, do a write click.
Hope this helps

Memory problem with loading a csv file and displaying 2 xy graphs

Hi there, i'm having some memory issues with this little program.
What i'm trying to do is reading a .csv file of 215 mb (6 million lines more or less), extracting the x-y values as 1d array and displaying them in 2 xy graphs (vi attacked).
I've noticed that this process eats from 1.6 to 2 gb of ram and the 2 x-y graphs, as soon as they are loaded (2 minutes more or less) are really realy slow to move with the scrollbar.
My question is: Is there a way for use less memory resources and make the graphs move smoother ?
Thanks in advance,
Ierman Gert

read from file test.vi ‏106 KB

Hi lerman,
how many datapoints do you need to handle? How many do you display on the graphs?
Some notes:
- Each graph has its own data buffer. So all data wired to the graph will be buffered again in memory. When wiring a (big) 1d array to the graph a copy will be made in memory. And you mentioned 2 graphs...
- load the array in parts: read a number of lines, parse them to arrays as before (maybe using "spreadsheet string to array"?), finally append the parts to build the big array (may lead to memory problems too).
- avoid datacopies when handling big arrays. You can show buffer creation using menu->tools->advanced->show buffer allocation
- use SGL instead of DBL when possible...
