Data smooth XY of a closed curve

Hello. I'm looking for suggestions on how to smooth the XY data that resembles the Attaché, a closed curve. The filter screw I looked all use X but not of X and Y.

Thank you.

Have you tried either:

(a) using B-Spline Fit?, or

(b) smoothing X and Y separately and recombine to give your smooth curve?

You can duplicate your data in the adjustment so that you get a more continuous curve at the ends.  Here's a quick, rough example:

  • Form data is not clear after closing

    Hi all

    I have fortunately developed these forms to 8.2 LCD until I got a call from customers say that there is a problem when they put the forms on a web page. If they meet one of these forms directly via IE6 (Acrobat 7) and then close IE upon arrival, the form is opened through the IE6 from the same computer all previous information remains on the form.

    This problem happens not to computers running Acrobat 9. So, it looks like some a compatibility issue with Acrobat 7 but cannot find a way to fix it. No, the upgrade is not an option and is not in my control.

    Thanks a lot for any help or suggestion!

  • smoothing by pieces

    Hi, I need to smooth out a curve, but the problem is, there are peaks which must not be smoothed.

    Currently, I select the area that needs to be smoothed and then I remove the data points and interpolate the values.

    the problem here is that is not specific enough or it will cost you a lot too long.

    is there another way to smooth only parts of a curve, or put a filter on the parts of a curve?

    Thank you.

    Hi Normann,

    If you have DIAdem 2010 (11.2) or later, then you should try the "Savitzky-Golay" filter in the palette "Curve Fitting" ANALYSIS - cela se smooth curve all by keeping the cutting edge information.

    Another option would be to try the "digital filters" in the palette 'Signal' ANALYSIS - if your noise is a frequency higher than your pics one works well enough low-pass filter (check the box 'Force the zero phase' in the tab 'Settings of the IIR').

    If none of this works, then the only way to apply the smoothing by pieces is to cut out the sections you want to smooth the new channels in new channels, smooth, then put the sections of return as well as the sections without smoothing.  There is no ANALYSIS dialog box to do, but it can be automated with a VBScript.

  • Closing a tab gives the same security that close a browser?

    Before the arrival of the tabs, we have been invited to close the browser and open a new after being on a site that has involved sensitive information.

    Closing a tab in Firefox gives the same level of security, or should I continue to close the entire browser?

    No, who does not have the same protection. Some data may be revoked by closing and restarting Firefox, but even so, you still have the data stored on the disk in the cache or cookies even if you closed all tabs open before closing Firefox.

    You can switch to private browsing to prevent storage of the data at all, or you can use clear history recent to clear the last hour or more if necessary.

    Firefox 4 and later versions Save the previous session automatically, so it is no longer need for the dialog box asking if you want to save the current session.

    Use ' file > leave ' or ' Firefox > Exit ' (Mac: ' Firefox > quit Firefox ") If you want to restore multiple windows or have problems with the restoration of the tabs.

    You can use ' history > restore previous Session ' to get the previous session at any time.

    There is also a button 'Restore previous Session' on the default on: Home home page.

  • Collect and display data from several workstations

    Currently, the data in the CSV format locally on several workstations running Labview and the format of the recorded data is the same for each workstation. Data are recorded roughly every 2 minutes at each station and at different times.

    Computers of these stations are connected network but no saves a copy of their files CSV to the server that I know is not ideal, but a part of memory original.  What is now there that a computer on the network brings together these data by workstations and then the poster showing trends in workstations etc. in graphic format and possibly Excel.

    What I'm looking for is some advice on the best way forward.

    I looked at shared variables as a possible solution, but it is work stations send their respective data to the 'central' PC or this PC "questions" workstations that seems inefficient.

    Another thought was using Active X workstations to write in an Excel file running on the "central" PC

    Finally thought that workstations have record their findings to a server and then 'central' PC to access that data, it brings together and then displays the results combined.

    There are several things that remains to be clarified.

    • All LabVIEW programs, individual data record data in the same format and the same number of data points?
    • Record all programs of LabVIEW at exactly the samerate?
    • Are all data on a be saved in a single file of the Machine, or each reading (at intervals of 2 minutes) in a separate file?
    • You are trying to combine data from different machines such that it is collected or after the entire collection was done, and all files have been written?
    • Another that the timestamp of the data file, is there a "time stamp" in (all) the individual data files?
    • If you assume that the data of different machines are more synchronized, you have in mind a way to combine the different readings of the time?  What happens if they are sufficiently different that, say, the Machine has 20 readings more (because it started much earlier) than other PCs?
    • If the machines are not saving at the same rate, how will handle you that?

    A single method, you might consider is to write a program that works on any network connected PC, including a no participate in the recording of data.  For simplicity, assume that each machine "participatant" starts at around the same time, saves exactly at the same rate, written a single data file and has already closed.  If the program "Combining" knows where all data files (because he knows the name of each machine and the location of the file on each machine), it can open all the files, collect all the data and treat it but want to (including a 'combined Excel workbook"writing with a spreadsheet separate for each PC, or combining them all on one sheet).  Just decide what you want to do in the context of the issues raised above.

  • Placing several sets of data on a graph (LabVIEW for Excel)

    I read in a 2D array (first rank values of the x axis, 2 values for the value axis in line, 30 columns) of a number of excel files. With each iteration of my loop for example, I read in 1 all of these 2D table data, and I'm tracing the curve (using Excel Insert graphic) before I close this file and move to the following.

    I want, however, must be able to generate 1 chart at the end with all sets of data together. So far, whenever I'm iterating, new data erased the old, and in the end I only get 1 set of data (the last game) on the 1 graph.

    I searched through the Forum similar topics, but 1) I have all my data read or typed into a nice big table, they come in the iterations instead, 2) my data values do not share the same values for the x axis, while the beach is almost the same (from 0 to 1) and the number of data points is always 30 (3) I don't think I can use shift registers because all my data is obtained in my loop, when I open Excel (also in the loop) files and read them, so I did not 'Original data' to initialize the shift register.

    Any suggestions on how I was able to read the data, graphics, read the new data, then graph on the same graph without losing my old data?

    Thank you!!

    Kalyie,

    You may need to force your data to have the same category axis.

    Another option would be to insert data in excel instead of a graph. From within excel you could have a set graph in place who knows where the X values and are there for each data set and it will draw it automatically.

    You can also try messing around with the Graph.vi of update to Excel.

    I had limited success with the Excel update Graph.vi, but worth a visit.

    Thank you

  • "425 can't open data connection" that mean?

    Having a problem with downloading the drivers for my printer and installing software

    Cannot open data connection error.

    Problem

    425 can't open data connection error

    Cause

    The 425 error means that the data channel is blocked or closed between you and the server you are trying to connect to.

    Solution

    • For active connections open ports 20 and 21
    • For passive connections open ports 21 and 1024 + (and higher)

    If it is impossible to establish a successful connection, check all devices that are between the client and the server to ensure that the appropriate ports are open (for example, routers).

    You are welcome. are ask you if you have disabled your mobile network and you connect to the wifi but the wifi service is unavailable, you will always be able to browser? don't I have that right?

    If that is what you ask, the answer is no. If your disconnected from your operator, but you are connected to your wifi, but wifi is not internet service, then basically you are always disconnected to the internet.

    If you are using PL/SQL, to get the results in the exact format you need should be easy.

    Using only SQL, you can get the acc_no on a separate line using GROUP BY GROUPING SETS.  You can use CASES and the GROUPING function to show only the acc_no on some lines and all, but acc_no on others.  May also get the acc_no and the trn_dt in the same column.  (You will need to explicitly call TO_CHAR for this).

    GROUP BY GROUPING SETS can also get a header line after the first acc_no.  If the VARCHAR2 headers are part of the result set, you will need to convert to strings, the total NUMBER of columns using TO_CHAR.

    Maybe some of you have done proof of formatting is not important to you.

  • How to validate the date

    Hi all

    I have the Create page two fields are there, that this is the date data type

    If the closing date should less than the opening date I raises the exception 'closing date should not less than the opening date.

    Suppose that if the user didn't enter the opening date and directly enter the closing date in my case, it goes with the exception of null pointer

    I have the partial action of fire on the closing date

    ' public void xxqtndatevalidate (String qtnvalidate, String qtndate) {}
