Chebychev Polynomial fitting results show multi lines

I am using "nonliear curve fit.vi" with defined Chebychev Polynomial  function to fit XY data.  Strangely, if I enlarge the upturn part, I clearly see the fitting results show multi-lines (2-4) . Please the the attached snapshot.

Thanks.
 I found the reason: the data X values are not mononicaly, i. e.  there are local oscillations at some region.
After sorting the raw data, the fitting results show single line. 
Is the sorting of X values necessary before Chebychev Polynomial fitting?

  • Different general polynomial fit results

    Hello,
    I've encountered a strange problem using the general polynomial fit: It seems that the outcome of this vi is computer dependent...
    I'm using labview 8.2.1, and tried to use the vi to get a polynomial fit (with an order between 12 and 20) on about 450 datapoints, which seemed to work fine... until I shared my vi with another person, where different results for the polynomial coefficients were obtained with the same datapoints (and the same parameter settings). I noticed that the differences get bigger when the requested order increases.
     has anybody encountered a similar problem?
    greetings,
    Hans

    Well, taking a 20th order polynomial does not make a lot of sense anyway. What are you trying to achieve? There are probably better ways to do whatever you want to do here. You are dealing with extreme intermediary values (e.g. 1500^20=3.32e+63) so a slight reordering in operation could change the outcome.
    Can you explain the differences between the computers? Is the other a different OS (e.g. mac vs windows)? Just curious.

  • Multi line ballon tool tip

    I have used ballon toolip, it have multiple lines to show the tool tip, but it is not working.
    I have added Component in bolloon tool tip to show multi line text , but still not showing correctly.

    Please suggest me the way .
    THE WAY
    1) Tell us what "not works fine" is supposed to mean.
    2) Tell use what the hell balloon tip means. Where did you get this? How do you call it?
    3) Post your code. USE FORMATTING TAGS. At least some code to give anyone a clue of what you are doing.
    4) Next time post into the correct forum.
    It never fails to amaze me when asked for more useful details people respond as you did here. By repeating, ad nauseum, information that was already clear but doesn't actually tell anything. Yes. We got that "it" only displays one line. But you didn't answer any of the questions asked which relate to what the hell is "it" and how the hell are you calling "it". etc.

  • Printing all text in a multi-line text field??  Can it be done?

    I was wondering if there is a way to print out a multi-line field and have all text entered print as well.  Currently, anytime someone enters more information in a multi-line text field on our form than is set to show without scrolling, when a PDF is created for printing from the results page, only the text that fits within the specified size prints.  You can scroll within the PDF and read it all, but I can't seem to figure out how to get all of the text to show and have that field resize accordingly on the printed copy.
    Is there a way?  Thanks.

    Is there an easy way to determine the character count that is visible in a given multi-line text field when designing the form, so if I want to allow 500 characters, the text box I create is large enough for 500 characters?  Obviously I can just do a trial and error process using a cut and paste of 500 characters and testing it, but is there an easier way?

  • Polynomial fitting for scatter plot

    Hi all, 
    I was wondering if there is any way to generate a polynomial fit to a scatter plot just like in excel. The data I am trying to fit has several y values for each x value. 
    Thanks
    Krish
    Solved!
    Go to Solution.

    Well, my "solution" above is a bit misleading, because the polynomial fit of course does NOT depend on the x ordering. If the x-values are scranbled as in your case, a maybe better solution would be to simply create a linear x-ramp over the data range and use polynomial evaluation to calculate a smooth best fit line. This has also the advantage tha a smooth curve is generated even if the data points are sometimes far apart.
    Here is one possible modification to show the technique.

  • Showing new line in Data in reports

    Hi All,
    We are having one column in Database which have the message with multi line and having proper indentation.
    But when i try to display it in report it is showing in single line without any proper indentation.
    The datatype of the column is varchar in DB.
    Regards

    It's because you are in a web browser.
    If you set this in a formula :
    CHAR(13) || 'Geek' ||  CHAR(13) || 'Geek'You will have no carriage return
    Now with a replace in the formula :
    REPLACE(CHAR(13) || 'Geek' ||  CHAR(13) || 'Geek',  CHAR(13), '<BR>')And you have set the format as HTML in the properties of the column, you will see the proper result.
    I assume that in your database, it's a vertical tab : CHAR(13) but it can be also :
    - a back space CHAR(10)
    - or a carriage return CHAR(15)
    Try them one by one in replacement of CHAR(13)
    REPLACE(Table.Column,  CHAR(13), '<BR>')Success

  • Permanently save line spacing in a multi-line text field

    Me: Adobe Acrobat 8 Pro, Windows Vista
    (I think the people who will be using the form have Reader 7 on Windows)
    I work in a doctors' clinic, and we use phone message sheets to document conversations between the patients/us/nurses/doctors, and I scanned the form and made it into a fillable PDF for our secretaries to fill out more quickly. The "message" area has pre-printed lines on it, and the multi-line text field I placed there needs to match up to the lines. I used the Rich Text Formatting options to set it to "Exactly 24 Points," but I can't get it to KEEP the formatting permanently. The only way I could get it to save the formatting in that field was to put a space in it and then save it, and then give that to the 2 phone secretaries. It works perfectly the first time, but instead of just closing/re-opening the file to start a new message, one of the secretaries highlights everything in the "message" field and deletes it... which deletes the line spacing formatting. I've told her
    b numerous
    times to leave that starting space in the field, but she "forgets" so all of her messages look messed up. So is there a way to force that line spacing
    b PERMANENTLY
    ???? Here's a shrunken screenshot of the field -- I wish I could just erase the lines altogether so the spacing wouldn't matter, but the secretaries type/print the message out, then the nurses/docs write on the page with pen so the lines have to stay. http://img187.imageshack.us/my.php?image=notepreviewph8.jpg
    Thanks!

    You can set the font size of the text. Then play with the underlines in the original document to match the needs of the font that is used. Print to a new PDF and then use replace pages to put the new page into the form without changing the form fields. I was able to do this with a word processing document by adding underlining in the document with 12 pt and setting the font to 12 pt in the text field. You can play with the font, the border of the field, and the underlining in the original document to get the desired result. Is this optimal, probably not. However it does the job.

  • Multi Line Text Custom Field

    Multi line text custom field is not coming in ms project Professional

    Pradeep,
    You cannot access Multiline text fields from Project Professional and in Project Server Views. These fields are for use in Project Details pages and with workflow for demand management in Project Server. Please refer to the article shared in earlier post.
    I would recommend you to create a Excel/SSRS report if you would like to show data available in this fields to end users.
    Hope this helps.

  • Address Book: Importing Multi-Line Fields

    A common and often unavoidable import format for Mac Address Book is Comma Separated Value files (.csv). Address Book cannot import CSV files that have multi-line fields, such as might be included in Notes, because it cannot tolerate embedded newline characters (a.k.a., carriage returns, line breaks). (See http://docs.info.apple.com/article.html?path=AddressBook/4.0/en/ad808.html. The CSV spec (http://en.wikipedia.org/wiki/Comma-separated_values) addresses this need by requiring that fields which contain newlines be enclosed in quotes, but Address Book doesn't adhere to this part of the standard.)
    Here's a way to import CSV files and have multi-line fields preserved:
    Using an editor, replace +every embedded+ newline character in the CSV file with "\n". Take care to not alter the newline characters that end each record. Import the resulting file into Address Book using the CSV option. Selecting the 'Last Import' group, export those specific records using the vCard option. Then delete those records. Then import the vCards previously exported. Presto!
    Apparently, although Address Book is blind to "\n" when importing CSV files, and exporting vCard fields, it interprets this character sequence as newline when importing vCards.

    Hi Adam,
    Thanks, but the problem is not importing to AddressBook, it is exporting.  I did discover from another that I can export very easily to a Numbers spreedsheet.  It is exceptionally simple.  But it will not export custom fields.  Someone said that is because of a vcard standard.  My custom fields are just "name" fields that I have labeled differently.  But Numbers does not support the name (it only takes the name of the card).

    >> Unfortunately I really need to form a dynamic query in a table valued function on the SQL SERVER. I have another tabled valued function that needs something returned as a table in order to further join the data. I am not allowed to use Stored
    Procedures in that function. <<
    You do know that real SQL programmers hate the proprietary nightmare of tabled valued functions?  This is how you procedural programmers avoid learning set-oriented declarative and functional programming. 
    Your mindset wants to write to a scratch tape or disk file (aka “tabled valued function result table”) just like you did BASIC, FORTRAN or COBOL. QL programmers do not have to materialize their data. We can use VIEW or a drive table as well as a base table. 
    >> Plus, there are occasions where I don't want to pass in a field [sic: columns are not fields] parameter or need to change a parameter list such that I don't wish the table function to filter by a particular field [sic] or other setting. <<
    What you want is a magical “Automobiles, Squids and Lady Gaga” function. An SQL programmer might write a complex VIEW then do simpler SELECTs off it. 
    >> My application pushes the WHERE clause from EXCEL to SQL to do the hard work as EXCEL is not the application in which I want to process the SQL statement and pass it via ODBC. I cannot run macros in Excel on the web.<< 
    This is a crazy language system. Usually we fetch data in SQL and then pass it to a math package, report writer, etc. We never keep logic (aka WHERE clauses) outside the database. 
    >> I am bummed about the fact that this feature doesn't work. It will up my server management costs to maintain unique tabular based functions based on WHERE clause query <<
    So stop writing those “tabular based functions”, change your mindset and start learning SQL and do it right.

  • Multi-Line Display Item

    I need to populate a multi-line display item in Forms 6i.
    The problem that I am having is the actual assignment to the display item.
    For example:
    :DISPLAY_ITEM := '10';
    :DISPLAY_ITEM := '11';
    This makes the display item show the value '11' only.
    I need '10' on the first line and '11' on the second line, etc.
    Thanks in advance,
    Patrick

    well, you can write:
    go_block('BL_BLK');
    first_record;
    :display_item:=10;
    next_record;
    :display_item:=11;
    but for this- 1. block should have one navigable item. 2. display_item should not be the first item of the block.
    Otherwise you will need to create a non-databse text_item with width 0 on the canvas for that block.
    Hope this helps.

  • Hello All. I am working on a form, but I need to format the leading in a multi-line text-field.

    Hello All. I am working on a form, but I need to format the leading in a multi-line text-field. The options for the text-field only show a font size option, but no other styling options. Is there a way to format the leading? Thanks!

    Not within ID, and I'm not sure it can be done in Acrobat afterward either.

  • How do I create a multi-line text box?

    I have a PDF that was tradionally printed and filled out by hand, and am trying to convert to an e-version.
    Everything is working great but I can't figure out how to make this one thing work. For example I have a section like this:
    More Info: _______________
    How can I make it so when one starts typing in the "More Info" section, their response continues from the 1st line to the 2nd, to the 3rd, etc.?

    You can set a text field to be multi-line and tick off the option to scroll
    long text to have it automatically wrap, but you'll have a problem with the
    first partial line, since form fields can only be rectangular. Another
    problem might be the lines themselves, since you'll have to use a font size
    that will fit them exactly, or it will look odd. I would suggest getting
    rid of those lines altogether. They are not needed when filling in the form
    electronically. It's a relic from printed out forms where people had to
    hand-write their answers.

  • Multi line column JTable

    Hi,
    I am working on JTable and I am using DefaultTableModel.
    I have a requirement that in one of the cells I need to show a multi line text which may contain 10 to 50 lines of text.I need to show all the text even on resizing the table.
    Can anyone give me suggessions regarding this.
    Thanks,
    Bussa.

    Hi,
    Write your custom JTableCellEditor and Renderer to install a JTextArea on the cell you want.
    You can set the size of the larger row separately via
    JTable.setRowHeight(int row, int value); To display the full text you should set
    JTextArea.setLineWrap(true);
    JTextArea.setWrapStyleWord(true);and set the width of the JTextArea static.
    after this calculate the height of the JTextArea and set it to the table.
