Data from text file shown in line graph at once

can anyone show me how to read the data from a txt file and show it in a line graph at once? my data is in the form of decimal number such as 3;45;67;89; thank you

Probably not, based on the fact that you can't even word your problem in a sensible manner. So even if someone read your mind to fill in the blanks, you wouldn't understand the solution. And it's probably just stupid homework anyway, cheater.

Cant get data from text file to print into Jtable

Instead of doing JDBC i am using text file as database. I cant get data from text file to print into JTable when i click find button. Goal is to find a record and print that record only, but for now i am trying to print all the records. Once i get that i will change my code to search desired record and print it. when i click the find button nothing happens. Can you please take a look at my code, dbTest() method. thanks.
void dbTest() {
DataInputStream dis = null;
String dbRecord = null;
String hold;
try {
File f = new File("customer.txt");
FileInputStream fis = new FileInputStream(f);
BufferedInputStream bis = new BufferedInputStream(fis);
dis = new DataInputStream(bis);
Vector dataVector = new Vector();
Vector headVector = new Vector(2);
Vector row = new Vector();
// read the record of the text database
while ( (dbRecord = dis.readLine()) != null) {
StringTokenizer st = new StringTokenizer(dbRecord, ",");
while (st.hasMoreTokens()) {
row.addElement(st.nextToken());

headVector.addElement("Type");
dataTable = new JTable(dataVector, headVector);
dataTableScrollPane.setViewportView(dataTable);
} catch (IOException e) {
// catch io errors from FileInputStream or readLine()

Charting data from text file in LabVIEW 5.1 for Windows

I am having some difficulties trying to figure out how to plot a chart with
data from a file. I would like to be able to read data from a text file
into a chart using LabVIEW 5.1 for Windows. I have looked in the help
within the program and online. I have also looked in the user manual and
the book "LabVIEW for Everyone". Could you please give me specific
instructions on how I would construct the program to be able to do this.
Thank you.

Hi Ellie,
It depends on how data is stored in that txt file. Usually you load the data into an array either using or , the array if necessary and send it to the graph indicator in required form. If you want a more detailed answer, send me a sample data file ([email protected]).

How to extract data from text file to database table

Hi ,
I am trying to upload data in text file to database table using GUI_UPLOAD function .what would be the program for that.
thanks in advance.

Hi,
I don't think you have a standard sap program to upload data from file to database table...
Instead you can create a custom program like this..

DATA: T_ZTABLE LIKE ZTABLE OCCURS 0 WITH HEADER LINE.
CALL FUNCTION 'GUI_UPLOAD'

Unable to find file error while loading data from text file to Oracle

I am using get_filename to get the filename and it is fetching correct value as the this variable refreshes in previous step of this interface.
KM used for loading is File to SQL
What would be cause of this error?
Thanks,

Hi,
Did a testing and following are the result
I have

1. Declaration of variable v_filename.
2. Refreshing variable v_filename.
3. Execution of Interface which gets the file name from v_filename and load into target table
Package executes successfully.
B> created package having steps like

CO-PA load data from text file

Hello
At present, in our company, we load data from Excel files to CO-PA. Is there any way to load those data to CO-PA from text files ?
I will be grateful for any suggestions.

You can create a structure using KEFA, assign the Value fields in KEFB and then use KEFC to upload data against that structure.
You have various file format options, but I don't think Excel is one of them... you have have to save the file as txt and upload.
Play around with those transactions and come back if you need additional help.
Cheers.

Unable to Upload data from text file into BEx Analyzer selection screen

Hi,
No response from BEx Analyzer when I am trying to upload around 40,000 material from text file into BEx Analyzer selection screen using "Upload selections" options. But I am able to upload only 10,000 material from text file. I never faced same kind of issue when I am using BEx Analyzer 3.x. Please let me know I have to change any settings related to BEx or any other.
Thanks

Hello
It seems you are reaching the .NET memory limitation informed in note 1040454.
Because 3.5 does not use .NET it can work that.

Remove duplicates while loading data from text file

Hi,
Data in text file (some times has duplicates) is being loaded into Oracle 9i database using Informatica. To improve performance, we would like to remove duplicates at the time of each load using Oracle procedure. Could you please help me with this?
Thanks,

No, our table doesn't have that. Most of the functionality is managed at the informatica level. Is there any other way? Thanks,

Continual plotting of data from text file

I would like help with automated plotting of multiple sets of data on one axis. The file attached shows a sample of the data where the first number (eg 405) is the reference and the next two are the date and time. The data after that all needs to be plotted in a different color. The A.A.. (or .....) does not need to be plotted, the N/A's can be assumed to have either no reading or the same as the previous day. The data needs to be read from a text file and then graphed. The sample shows only a few variations and the reference number is incremented by 1 (I have shown random data) everytime the data is obtained from the source. Is this possible. If it is possible, the system will then need to be expandable to be able to updat
e the graphs daily as the new data is obtained (although this is not so important at the moment). Can anyone please help me with detailed instructions if possible. All help will be greatly appreciated.
Thanks

SAMPLE.txt ‏1 KB

I have written a rough vi for you in LV 6.0. Basically it shows how to open a file and write the string to an indicator. Then create an array from the numerical parts of the string which are plotted in a graph. I have assumed that the date/time and ref numbers will always be of the same format on each line of text.
I'm not sure if i have done exactly what you want, but should give you an idea of what to do. Let me know if you have any problems..

Read data from text file one by one using for loop

Dear Forum
I want to read data of single colum of text file inside the for loop one by one(for each iteration value must be replaced by another value of text file).This value is used by a formula inside for loop. also after completion of iterations the values must be plotted on xy graph. How to do it.? please help me.
profravi

It's not very efficient to read a file line by line. Much simpler to read it all at once and then auto-index the results inside a for loop. The image below shows a generic solution to your problem. This assumes that the data in the file is in a single column.
I would also recomend checking ou the learning LabVIEW resources here.
I would aslos suggest that since this type of question is not specific to either NI-Elvis or the LabVIEW SE, you should post similar questions to the LabVIEW board. If you have problems, attaching a sample of the text file would help.

Deleting data from text files

Hi there,
I am having a real battle trying to delete data from a text file I am using. There seems to be this giant cloud with Java, where there is no real easy way to delete text from a file??
I have a JFrame with two textfields on it where you enter the username and pcname. There is a OK button once you have entered those details.
On action event I would like those two details, to be removed from the text file that has been read in.
I have a text file like this:
bob
pc1
bill
pc2
The data above gets written no problem, one at at a time using the below.
File f = new File("\\c:\\filename.txt");
String strToWrite;
try
FileOutputStream fstr = new FileOutputStream(f);
strToWrite = username1+ '\r'+'\n' ;
byte[] bytes = strToWrite.getBytes(); fstr.write(bytes);
strToWrite = pcname1 + '\r'+'\n' ;
byte[] bytes2 = strToWrite.getBytes(); fstr.write(bytes2);
strToWrite = username2+ '\r' +'\n' ;
byte[] bytes3 = strToWrite.getBytes(); fstr.write(bytes3);
strToWrite = pcname2 + '\r'+'\n' ;
byte[] bytes4 = strToWrite.getBytes(); fstr.write(bytes4);
catch (IOException e)
System.out.println("Error -- " + e.toString());
To read them back in I have made the follwoing:
BufferedReader br= null;
Count = 0;
try
br = new BufferedReader(new InputStreamReader(new FileInputStream("\\c:\\filename.txt")));
String s = "";
while((s=br.readLine()) != null )
Count = 1;
     //System.out.println("Data is " + s);
     inboundtext = s;
     if ( Count == 1 )
break;
while((s=br.readLine()) != null )
//System.out.println("Data is " + s);
inboundtext = s;
Count = 2;
if ( Count == 2 )
break;
catch(IOException ie)
finally
try
     if(br!=null) br.close();
catch(Exception e)
Now the above I know, is reading each line of the text file one at a time.
Now what I would like is that when the text that we got from the textfields, using getText(), be removed from the file without destroying the rest of the records in there? Why is it so easy to add and replace files, but not do any deleting from them?
please help!!

sorry, FileOutputStream fstr = new FileOutputStream(f);
should be FileOutputStream fstr = new FileOutputStream(f, true);

Then I need to insert the all the value for this three column into a table which has the three column name ID, Name, Age
Anyone knows? I need to do this urgently...Thank in advanced

1. Use BufferedReader and read the file line by line.
2. Loop thru the file and do the following steps with in this loop.
3. Use StringTokenizer to seperate each line into three values (columns).
4. Now create a insert statement with these values and add the statement to the batch (using addBatch() method of PreparedStatement or Statement).
5. Finally (after exiting the loop), execute these batch of statements (using ps.executeBatch()).

Fetch data from text file to print

Dear All,
I am trying to fetch data from a text file in to Oracle database to print.
The problem I have is that I cannot gather data because this is a statement, generated by a report utility and the data consist of multiple dimensions.
First 3 fields of data are in the first 3 rows of a page and the rest is displayed column wise for the next 20 rows (5th row to 24th Row). Then there is a page break character ASCII (012) (Hex - 0C)then the next record starts.
Please give me a solution to fetch first 3 lines to one master table & the column of data to a detail table.
I konw I can fetch data using SQL Loader but the problem is how can I seperate multiple dimention data.
Sample
<page breake>
Code:123456
Name:1233445566
Address:aaaaaaaaaaaaa
Detail1 Detail2 Detail3
======= ======= =======
AAAAAAA BBBBBBB CCCCCCC
AAAAAAA BBBBBBB CCCCCCC
<page break>
Code:123457
Name:AAAAAAAA
Address:AAAAAAAA
Detail1 Detail2 Detail3
======= ======= =======
AAAAAAA BBBBBBB CCCCCCC
AAAAAAA BBBBBBB CCCCCCC
<page break>
Thank you in advance..
Regards, Shaamil.
