How do i save a graph for a specific length of time

Dear All,
I am using a magnetic field sensor on a mine detector. Lets say the minedetector sweeps the sector for 10 secs. i want your help on the following
1) how do i save the waveform chart for the whole ten sec. All i know is that i came across an example where i can save the chart at a specific point as a jpg. But that example is also for a graph. for the chart i suppose we need to change the array in some way.
2) If i save the value of magnetic field obtained at every sample in an array, can i save it as an excel file. how do i do that.
Best regards
Regards

Using LabVIEW 8.2
Solved!
Go to Solution.

Whenever I'm asked to reproduce chart data, I use Excel. In other words, your #2. The charts are graphical items floating along on the screen. Once they are gone, they are gone. You could save the chart to jpg everytime the chart gets full, then string it together later, but why? The data are the data, not the chart.
The easiest way to save an array for Excel is to simply write the data to a text file, and have LabVIEW save the file as a *.csv file. This file can then be directly opened in Excel, and then plotted.
The other method would be to have LabVIEW save directly to an Excel worksheet. There are lots of examples of that on the forum.

Display "global" text caption for a certain length of time

I hope I can explain what I'm trying to do...
I have a text caption that I want to conditionally display for a fixed length of time at the start of most of slides in my project.
The caption is placed on an introductory slide in the project, in a hidden state.
Then I have created a Conditional Action to Show the caption. This Advanced Action is then called On Enter for the slides where I want to display the caption. However, I need to be able to hide the caption again after a couple of seconds.
So essentially I want the following logic:
On slide entry, if displaying caption, then Show Caption, Wait 2 seconds, Hide Caption.
But I can't see how to do this using a single text caption that is available project-wide.
Any suggestions would be greatly appreciated!

In case you are using "Clear history when Firefox closes":
*do not clear the Site Preferences
*Tools > Options > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
If you have software like Advanced SystemCare (Surfing Protection feature) that might reset some files to older versions to protect these files against changes then check the settings or uninstall this software.

After i designed a website for desk top how do i save the site for cell phone

after i designed a website for desk top how do i save the site for cell phone use

I don't think you can simply save a desktop design as a cell phone design. While in Muse and in the site plan view for you website you should see three tabs near the top of the page. If you click the "Phone" tab, you will get a pop-up dialog box asking which element you would like to copy over from your desktop site (if any). You must then design the site for cell phone use. You can use the same objects, pictures, etc. from your desktop site and Muse should automatically optimize those elements for phone use. However, Muse does not automatically take a desktop design and create a cell phone design from it.
As I understand it, Muse uses user-agent detection to decide which site it wants to display to the user. You however, need to create the different versions of your site so that Muse can apply a specific design for the intended use.

How do I save my setup for Photoshop Elements 11 that I created for category - sub-category - Keyword Tags

how do I save my setup for Photoshop Elements 11 that I created for category - sub-category - Keyword Tags I would like to use the setup for other Photoshop Elements

First are you going to use the same keyword/categories hierarchy in the same Elements version (or newer)? If so, using the backup/restore process will also restore your hierarchy.
If you want to create the same hierarchy in an older Elements version, it's possible to save that hierarchy in a special text file and to restore it in the new catalog in the destination computer. It's also possible to restore it in another catalog in the same computer.
Look at the title bar of the keywords panel. Next to the '+' sign on the right, you see a small icon which opens a menu offering the option to save or to restore the text file.

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.

How to stop Firefox from checking for add-on compatibility every time it opens?

How to stop Firefox from checking for add-on compatibility every time it opens?

That can be a problem with the compatibility.ini file in the Firefox profile folder.
Try to rename (or delete) the compatibility.ini file in the Firefox profile folder to see if that helps.
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*http://kb.mozillazine.org/Profile_folder_-_Firefox
You can also check for problems with preferences.
Delete possible user.js and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.

HI
the RBS maintainer was run from one of web front end server And for one content database , that fine
but I now know this information only this did by other administrators.

How to write data to the DAQ for a specified length of time while still reading the input data?

Hello,
I'm using labview 2012 and am trying to turn on a signal for a specified length of time in labview at the press of a button. The signal goes into an AO (PXI 6723) through my system, where the voltage gets divided by 2, the read in through the AI (PXI 6225). I want to write and read voltage constantly and then have a spike of voltage after pressing a button in LabView while still reading the voltage value for the specified amount of time.
Parameters:
constant voltage of 1 volt to Analog output (reading and writing) seen through a waveform chart.
for 1 second, turn on 3 volts and see the response on the waveform chart.
My specified delay time does not match the elapsed time. I am having difficulties doing this. I have attached the VI.
( I can't upload a functional VI since it shows "the contents of the attachment doesn't match its file type") How can I attach the VI?.
Thanks!
Eduardo

Mike,
Thank you for your reply! I greatly appreciate it. I currently don't have any DAQmx timing in my application. I tried using it and, without really understanding how it works nor how to manipulate it, the whole test end up taking a long time to change the values i.e. too slow.
The DAQmx timing I used was the sample clock since it was for analog signals, but I don't really understand the buffer, what that means nor how to use it. inputting a rate time for it also made my test slower. The rate time is the samples per channel per second, but I'm not sure how to determine a number so that I am collecting the data I need and take into account aliasing.
I know the PXI 6225 has the capability to read 250kS/s (which I am assuming it's kilosamples per second or 250,000 samples per second). I am using 32 differential channels. I have read that I have to divide the maximum sample rate by the number of channels, (250kS/s / channels) but I don't know if I should count the number of total channels (64) or differential channels(32). In other words, is the per-channel maximum rate:
250,000/32 = 7,812.5 samples per channel per second, or
250,000/64 =3,906.25 samples per channel per second
Furthermore, If I know the number of samples per channel per second, how can I implement that knowledge to the DAQmx sample clock so that my sampling is as fast and as accurate as it can be?
I attached an image of my DAQmx functions in my code, I merged all the stacked sequence structures in paint so you can see them.
thanks for your help!
Eduardo

How can I save zoom setting for a DOCUMENT so it opens at that setting?

I find an optimal zoom setting for a document I'd like to use (say 42%) and want the document to open at that setting. I save the document with File>Save Copy. However when I open the document, it opens at the DEFAULT zoom setting set in the Preferences for program. If I change the zoom level here to what I desire for that document, obviously all documents will open at that default setting.
How can I save my desired zoom level for a document, which will most likely be different for EACH document, and have the saved document open at that setting?
This seems like a trivial exercise / feature that should be easy to implement BOTH by the programmers of the software and the user setting the zoom level.
Also, I want to suppress the bookmarks sidebar. I save without the bookmarks but the documents opens with the side bar. Can't THIS be set for each document?
Why is it so difficult to tailor the viewing of a document to exactly what the viewer wants?

OK. Sorry for the mistake in posting the question here.
Again it seems like it should be trivial to save a document in the Reader with a viewer's desired zoom setting. I find this very helpful as I like to use a zoom setting that when scrolling down the document only one full page of the document is viewed (like turning the pages of a book). Without this feature, partial pages are displayed when scrolling unless one experiments to find the correct zoom setting (often it is 60%). One must do this every time one opens the same document, unless one remembers the zoom setting.
Oh well ....

How can i save my annotations for future use?

Hi,
I have several ePub files in iBooks that I annotated, with the highliter as well as the post-it feature.
Now how can I save those for fututre use? I'm not talking about iTunes sync/restore. I'm talking about removing the book from the iPad and use it back in, say, 4 years, or even pass it to someone else along WITH the highlighted sections.
In a word: keep the book with the annotations on the side OR keep the book embeding the annotations.
This is for ePub of course, not purchased in iTunes, but free books or purchsed ePub from external sources (like O'Reilly).
After playing with DiskAid, I got a copy of the internal annotation database (my iPad is not jailbroken) and was able to see all the notes in it. But any existing tool to actually extract and link those notes to a specific book would be exactly what I would need...
Possible? Hopefully yes...
Thanks for any help.

How do I save password info for a site when Firefox does not offer to?

Certain sites that require a password I do not remember ever being offered the opportunity to save a password for that site, so it doesn't show up in rejected, and I can find no option to get Firefox to offer to save password info for me...aside from this I have been very pleased with Firefox since i made the switch in Sept...Thank you, a technically challenged grandmother...

If a website doesn't offer to store the password then chances are that it doesn't fill that password either if you use the "Saved Passwords Editor" extension. You can only use that extension in such a case as a reminder in case you forget the password.

How do I save a password for a site if I am not prompted by Firefox?

I am trying to save a password for a site that I previously chose not to save one for.
I have tried:
Going into my exceptions list - it's not listed
Going into my saved password list - there's no option to manually add a site
Checking the forums but there is no solution that has worked
In one forum I followed one solution. I opened a new tab, typed in about:permissions and searched for the site. It was remembered and set to 'Allow' password storage but 0 passwords were stored so I could not use the 'Manage Passwords' button. I even tried the 'Forget About This Site' button to see if navigating back to the page would reactivate the password prompt but it did not.
Little help?
Thanks,
Megan

I am having this problem with logging in to my Craigslist account. The autocomplete will enter my user name after typing the first letter, but the password does not, and I'm not prompted allow it to be saved. It used to autocomplete the password, but after I changed the password and deleted the old one in Saved Passwords, it won't save the new one. The bookmarklet doesn't seem to change anything. If this a CL issue, is there a way to circumvent it?
