Displaying Parameter in Graph Builder

Hi
I am passing parameter to graphic builder. How i caA display this parameter at run time. Trying to create text item seems creating something like a label not a text filed to which i want to set the value= p_parameter1
Thanks

Asim
in your select statement you can check if the employee has not its picture or picture field is null then return logo. for this you have to assign some default value to the field Like 'N' is default value for picture field so when there is not picture or field is null then 'N' will be its default value and you can check in your query like
SELECT DECODE(pict, 'N',Logo,pict) FROM emp

Passing parameter to Graph Builder

Hi
If somebody has experience with Graph Builder- how i can show(at run time) the value of parameter wich i am passing to my chart item in Graph Builder?
I am trying to assign a value to a text item in my Display(in Graph Builder).
In Open trigger i am using :text_item1 := :param1
and i got error bad bind variable"Text_item1"
How i have to refer to e text item in Graph Builder?
And also - how i can create a chart wich query is based on stored procedure?
Thanks

Hi Galia,
Assuming you are working with Forms 6 or above, you have to create a block with a display_item object.
Using the button on Layout Editor you will be prompted for going with Graphics Wizard or manual building.
If your grapho is not so complex, I think the first one it's the best way to include a grapho inside a block of your form...
Opening/displaying/updating your grapho will be automatic (but you can set differently few properties of this item too).
Refer to Forms Help for improving your graphics, even I think they are not Forms' best feature...especially on web envinronment.
Hope this will help you,
Marco

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

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...

How to display on the graph three or more waveforms where time scale is not an index of array but a real time

How to display on the graph three or more waveforms where time scale is not an index of array but a real time:
I measure three voltages Va, Vb, and Vc on my Test stands every 3sec. So I’m building four arrays (Va, Vb, Vc, Time) and combine all in one.
Time
Va
Vb
Vc
0
5
3.5
2.8
3
4.9
3.6
2.9
6
4.8
3.8
2.1
Now I need to show on the graph in which scale X is “Voltage” and scale Y is “Time”.
How can I do it?
Thanks a lot,
Boris

Hi, thanks all your reply.
You may find "points_to_bar_graph.vi" from this website, I find it by this way.
I will ask a stupid question: I don't have any photo processing software, how can I save the vi into a picture format?
So here I just paste it into word document.

My performance is very slow when I run graphs. How do I increase the speed at which I can do other things while the data is being updated and displayed on the graphs?

I am doing an an aquisition and displaying the data on graphs. When I run the program it is slow. I think because I have the number of scans to read associated with my scan rate. It takes the number of seconds I want to display on the chart times the scan rate and feeds that into the number of samples to read at a time from the AI read. The problem is that it stalls until the data points are aquired and displayed so I cannot click or change values on the front panel until the updates occur on the graph. What can I do to be able to help this?

How to display a 'Directed Graph Structure' in ADF

Hi
I have a requirement where I have to display a 'Directed Graph Structure' (one with multiple nodes and links ). http://flylib.com/books/en/2.264.1.159/1/
As of now there is no dvt component to support it.
So I used a third party JS lib to draw the graph in HTML.
Now I want to open this HTML page as pop in my adf application using JS.
Please suggest me how to do that or any alternative way to display the graph structure.
Thanks

is there another way? or is it just not possible?

DISPLAYING PARAMETER LAYOUT WHILE EXECUTING REPORTS THROUGH WEB

Good Day all,
With reference to the above subject i would like to ask for help that how can i get the parameter screen when a user/clients runs reports through browser web ?.
i hardcoded in the source and deployed on the server,its working perfectly.
I need to define the parameters,is there n e way/s please assist.
second is there any method/s or example by which i can call report through form server,
the form server is working ok.. need to call a report through this form ,
please assist with your earliest
awaiting for your earliest and positiver response regards

Mohd,
(1). To display parameter form in web, you can either pass parameter "paramform=yes" in url, or specify %P in corresponding key of the cgicmd.dat file.
(2). To call Reports from Forms, you can either call reports 9i server directly (via run_report_object), or via web.show_document() to call the cgi/servlet.

Display multiple Waveform-Graphs on a separate Frontpanel

Hi there,
I'm looking for a solution to display multiple waveform-graphs on a separate frontpanel.
In my application I measure a number of channels (number is a user-input). The signals I want to display each in a separate waveform-graph, because they have different scales. They shall be arranged that way, that the user can switch them on and off or arranges them on the screen, while the application is running (measuring). He shall also be able to maximize all graphs or a graph window to have a closer look at the signals.
I already tried several things.
1. I placed the maximum number of graphs in a separate vi, which I start in my application and then switch the frontpanel on and off via a property-node. The values I also write via the references of the waveform-array, which I place in an array. This way I can also change the propertys of each plot (scale, xmin xmax, etc), but I always have all graphs on the screen (also the unused).
2. I then tried to change the visible-property of the unused graphs, but I cannot scale and rearrange the remaining graphs to the full frontpanel-size, because this property is read-only.
3. I placed just one waveform-graph in the vi and then start as many vis, as I need. This is cool, because I also can program the position and size of each frontpanel, so that they are arranged in a grid on the display, but all the graphs are separate and it is uncomfortable if the user had to arrange them separate. The windows need to be docked ore something like that.
4. I tried to place the graph-vis in subpanels, but then I cannot change the position and size of the vis programmatically.
Has anyone an idea, how to solve this?
I am using LabView2009Sp1 Professional Development System
Thanks Norman

Thanks so far,
I attached some examples of what I tried already.
1. MaximumNumberOf Graphs - I show 6 graphs although only two are needed. I cannot rescale the used ones to the full screen size, because the property is read-only
2. RescaledFrontpanel - I switch the unused graphs to invisible, resize the frontpanel to hide the unused graphs, but now the window is not zoomable
3. GridOfWindows displays the desired grid of graphs in separate windows, but they don't stick together
I hope this explains the situation better.

Need Help: Dynamically displaying parameter values for a procedure.

Problem Statement: Generic Code should display the parameter values dynamically by taking "package name" and "procedure name" as inputs and the values needs to be obtained from the parameters of the wrapper procedure.
Example:
a) Let us assume that there is an application package called customer.
create or replace package spec customer
as
begin
TYPE cust_in_rec_type IS RECORD
cust_id NUMBER,
,cust_name VARCHAR2(25) );
TYPE cust_role_rec_type IS RECORD
(cust_id NUMBER,
role_type VARCHAR2(20)
TYPE role_tbl_type IS TABLE OF cust_role_rec_type INDEX BY BINARY_INTEGER;
Procedure create_customer
p_code in varchar2
,p_cust_rec cust_in_rec_type
,p_cust_roles role_tbl_type
end;
b) Let us assume that we need to test the create customer procedure in the package.For that various test cases needs to be executed.
c) We have created a testing package as mentioned below.
create or replace package body customer_test
as
begin
-- signature of this wrapper is exactly same as create_customer procedure.
procedure create_customer_wrapper
p_code in varchar2
,p_cust_rec customer.cust_in_rec_type
,p_cust_roles customer.role_tbl_type
as
begin
//<<<<<---Need to display parameter values dynamically for each test case-->>>>>
Since the signature of this wrapper procedure is similar to actual app procedure, we can get all the parameter definition for this procedure using ALL_ARGUMENTS table as mentioned below.
//<<
select * from ALL_ARGUMENTS where package_name = CUSTOMER' and object_name = 'CREATE_CUSTOMER'
but the problem is there are other procedures exists inside customer package like update_customer, add_address so need to have generalized code that is independent of each procedure inside the package.
Is there any way to achieve this.
Any help is appreciated.
// >>>>
create_customer
p_code => p_code
,p_cust_rec => p_cust_rec
,p_cust_roles => p_cust_roles
end;
procedure testcase1
as
l_cust_rec customer.cust_in_rec_type ;
l_cust_roles customer.role_tbl_type;
begin
l_cust_rec.cust_id := 1;
l_cust_rec.cust_name := 'ABC';
l_cust_roles(1).cust_id := 1;
l_cust_roles(1).role_type := 'Role1';
create_customer_wrapper
p_code => 'code1'
,p_cust_rec => l_cust_rec
,p_cust_roles => l_cust_role
end;
procedure testcase2
as
l_cust_rec customer.cust_in_rec_type ;
l_cust_roles customer.role_tbl_type;
begin
l_cust_rec.cust_id := 2;
l_cust_rec.cust_name := 'DEF';
l_cust_roles(1).cust_id := 2;
l_cust_roles(1).role_type := 'Role2';
create_customer_wrapper
p_code => 'code2'
,p_cust_rec => l_cust_rec
,p_cust_roles => l_cust_role
end;
end;

Not possible to dynamically in a procedure, deal with the parameter values passed by a caller. There is no struct or interface that a procedure can use to ask the run-time to give it the value of the 1st or 2nd or n parameter.
There could perhaps be some undocumented/unsupported method - as debugging code (<i>DBMS_DEBUG</i>) is able to dynamically reference a variable (see Get_Value() function). But debugging requires a primary session (the debug session) and the target session (session being debugged).
So easy answer is no - the complex answer is.. well, complex as the basic functionality for this do exists in Oracle in its DBMS_DEBUG feature, but only from a special debug session.
The easiest way would be to generate the wrapper itself, dynamically. This allows your to generate code that displays the parameter values and add whatever other code needed into the wrapper. The following example demonstrates the basics of this approach:
SQL> -- // our application proc called FooProc
SQL> create or replace procedure FooProc( d date, n number, s varchar2 ) is

Saving waveform to retrieve it back to display on waveform graph

I want to save a waveform that I acquire through my hardware and display it on a sweep chart. Its a time based voltage acquisition. I tried using write to spread sheet or save waveform options in LabVIEW 2009. But when I tried to read it, it only shows me 1 cycle of data(I will be suing a graph here because I want to add cursors to it). I want the exact same whole waveform to be displayed on a graph as I had acquired it. I want to avoid using express vi's since I will be acquiring 10 channels simultaneously so I dont want to slow down the execution speed.
I am attaching the base vi that i made to read and write the waveform to a file(I am using simulate signal in this attached vi just to simulate a square wave and check my logic functionality).
Can anyone help, please!
Thanks in advance.

First of all, the "Append" should only be True when i does not equal 0.
Secondly, you are only dealing with 1 signal, so have the dynamic data converter output a 1D array of scalers. I then found that I had to transpose the spreadsheet on both sides (read and write).
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Help needed with passing data between classes, graph building application?

Good afternoon please could you help me with a problem with my application, my head is starting to hurt?
I have run into some difficulties when trying to build an application that generates a linegraph?
Firstly i have a gui that the client will enter the data into a text area call jta; this data is tokenised and placed into a format the application can use, and past to a seperate class that draws the graph?
I think the problem lies with the way i am trying to put the data into co-ordinate form (x,y) as no line is being generated.
The following code is from the GUI:
+public void actionPerformed(ActionEvent e) {+
+// Takes data and provides program with CoOrdinates+
int[][]data = createData();
+// Set the data data to graph for display+
grph.showGrph(data);
+// Show the frame+
grphFrame.setVisible(true);
+}+
+/** set the data given to the application */+
+private int[][] createData() {+
+     //return data;+
+     String rawData = jta.getText();+
+     StringTokenizer tokens = new StringTokenizer(rawData);+
+     List list = new LinkedList();+
+     while (tokens.hasMoreElements()){+
+          String number = "";+
+          String token = tokens.nextToken();+
+          for (int i=0; i<token.length(); i++){+
+               if (Character.isDigit(token.charAt(i))){+
+                    number += token.substring(i, i+1);+
+               }+
+          }     +
+     }+
+     int [][]data = new int[list.size()/2][2];+
+     int index = -2;+
+     for (int i=0; i<data.length;i++){+
+               index += 2;+
+               data[0] = Integer.parseInt(+
+                         (list.get(index).toString()));+
+               data[i][1] = Integer.parseInt(+
+                         (list.get(index +1).toString()));+
+          }+
+     return data;+
The follwing is the coding for drawing the graph?
+public void showGrph(int[][] data) {+
this.data = data;
repaint();
+}     +
+/** Paint the graph */+
+protected void paintComponent(Graphics g) {+
+//if (data == null)+
+     //return; // No display if data is null+
super.paintComponent(g);
+// x is the start position for the first point+
int x = 30;

Displaying parameter form in Portal

we have reports created using 9i reports builder and are running them using 9ias portal version 9.0.2.2.22
can we get the parameter form displaying before the report is run, as at the moment it either gives an error because parameters have not been entered, or it runs with the last used parameters which may not be the ones required for this time ( and so reports take awhile to run)

hi
You could look at http://www.oracle.com/technology/products/discoverer/files/viewlets/1012_dashboard.html
I don´t remember if here you create the simple parameter form. But there is a portlet called "Simple Parameter Form", you can find it at Portlet Builders. You can reach this link in your Oracle portal in the Edit link, in the add portlet link.
then you can follow the wizard to create your parameter portlet
After this step you should link the parameters you send through this portlet with the page and the other portlets.
I hope this help
