Plot editor in LabVIEW.

Hello,
In MATLAB there is an option to save the plot as *.png or other formats and also somethink like *.fig. Later when the user wants to check the plot he can load the *.fig file into the figure editor and can be edited which makes easy for the user to recheck the data.
Is there any such functionality or driver or application even in LabVIEW?

@ CMW: I am aware of this export option but it is used for saving data in excel, as a graphics(*.png,*.bmp*.eps,...). This was not my question. Even if you save the data in excel you still to write another program to import the data and plot. if you compare the option with matlab first you plot the data and then save as *.fig. Later some time later may be after 100 years or so.... if you open *.fig file you can even recolor, change the label of the x and y axis and so on... Is labview has such a compatability??

Old Icon Editor in LabVIEW 2012

I'm observing a 'weird' behavior with the icon editor in LabVIEW 2012, suddenly I'm starting to see the 'old' editor on my VIs
Anyone seen this before?
Thanks,
<<-N->>

I've been seeing a similar problem. First I get error shown in the attached, then the icon editor version shown in the attached. I have tried reinstalling the LabVIEW2012 as well as doing a repair.
I am using Windows7. I have a lab computer with the same software which works fine so there is something funny about my laptop.

Waveform graph plot legend in labview 8.5 won't respond to arrow keys?

I heard labview 8.5 fixes most of the problems that plague 8.2, so I recently installed it to try it out and see if it is worth the effort of another upgrade. Messing around today, I found an issue that wasn't related to the installer itself.
The plot legend on a waveform graph doesn't appear to respond to arrow keys for precise placement. It doesn't matter whether auto-size plot legend is turned on or off. When I want to place a plot legend very precisely, just like with any other labview control I like to use the arrow keys to get things perfectly aligned. I want to make the plot legend perfectly in the corner of the graph but its very hard to get it placed right with just the mouse.  In labview 8.5 it seems like plot legends no longer respond to arrow keys.
Can anyone confirm this or know of a way to precisely place the plot legend in labview 8.5?
-Devin
I got 99 problems but 8.6 ain't one.

Ben,
I checked the snap to grid hypothesis. Even when activated the arrow keys still allow an accurate positionning of the objects at pixel level.
That's so nice that I changed my setup. I now have a reasonnably large spaced grid (50 pixels) with an invisible grid (contrast adjusted to zero). That should make object positionning and dimensionning much faster than before.

Reading Waveform (.hws) files from Analog Waveform Editor into LabVIEW causes read errors

Hi Gang,
In my application, I want to create files Using the Analog Waveform Editor and then, through LavVIEW, play them out through an D/A.
I've not been able to read the .hws file into LV. I've tried two methods:
Using the Read Waveform VI in the Waveform palette, yields Error -1821.
I looked in the knowledgebase and found the article "Using the Analog Waveform Editor and HWS Files with Multifunction DAQ Devices" That recommended using the HWS VIs that are a part of the FGEN driver. I tried that and get an Error -21515.
The file I want to read is quite small, only 20 samples. Is there some limitation on .hws files or the Waveform Editor I'm not aware of?
I've attached the file if anyone is willing to experiment. I had to change the extension from .hws to .txt to be able to attach it.
All responses will be appreciated.
Thanks,
Roger

Interesting. I tried to look at your file with the low level read .hws file vi's and I too got error -21515. So I tried the NI-HWS express load.vi and it looks like it worked. I'm not familiar with the analog waveform editor...does it store using the dynamic data type? Oh I converted the dynamic data to 1d array of waveforms using the convert from dynamic data.vi.

Call Template Editor in LabVIEW

Is it possible to call template editor in LV? I searched around and found using command prompt is asolution, but is there any VIs or a combination of VIs that can realize this function in new version Labview?
Following is the link that calling template editor using command prompt:

Thanks for your kind help!

Hello,
you can open the tempate editor via the command prompt.
Save the templates on disk and read them in your Labview program.

Plotting graph in LabVIEW from MySQL data table

Is there any possibility to plot the data from MySQL data table in LabVIEW graph/chart??
can somebody help me??
thanks...

I am new with LabVIEW and I am also with the same problem.
No problems to write data into MySQL, but when trying to read data neither "fetch element data" or "get properties" answer !
It is not possible to get a simple recordcount using the "get properties". The same script give the right answers with MS Access, only changing the DB reference from "connection string" to a "UDL". Does somebody can post an example retriving data (that runs ok even with a WHERE clause in the recordset) using MySQL ?
The connection string I am using is:
Driver={MySQL ODBC 5.1 Driver};Server=127.0.0.1;Database=DBname;User=root;Password=xxx;Option=785;

Controlling Menu Bars of Windows Applications like IE and Editor with LabVIEW 6

Hi everybody !
I'm trying to develop a vi (LabVIEW 6) which controls menu bars in
Windows Applications (IE, Editor, etc.) like "File-Save As..." or
"View-Source...". I'm pretty sure I've got to use the ActiveX
possibilities in LabVIEW, but I haven't been succesful. Any comments
will help.
Thanks

You can use Win32 API to simulate a key-press (e.g. ctrl-S for Save)
for IE or any window applications, as long as the application has
short cut for menu items, and active.
You can use external code (VC, VB, dephi, etc..) to build DLL, CIN, or
ActiveX, call them in LabVIEW.
I made "Send Keys.vi" in G Toolbox.
If the menu item doesn't has a shortcut, you can send a message (use
spy tool to find out) to the application.

Equivalent de la fonction plot (Matlab) sur Labview

Bonjour,
Je suis débutante un Labview et j'ai un petit problème :
Dans mon VI il y a une partie Matlab qui trace 4 cercle :
for m=1:4
xe(m,: ) = R(m)+cos(alpha)*xc(m);
ye(m,: ) = R(m)+sin(alpha)*yc(m);
end
Si j'écris : plot (xe(m,: ),ye(m,: )) dans la partie Matlab, quand je lance mon VI il me trace bien 4 cercles dans une nouvelle fenêtre.
Maintenant, j'aimerais que mes xe et mes ye (mes cercles) apparaissent sur ma face-avant et non dans une nouvelle fenêtre. Pour ça j'ai essayé d'utiliser Graph XY mais ça ne fonctionne pas (je pense que c'est parce que xe et ye sont tous les 2 en 2D).
J'aimerais donc trouver l'équivalent de la fonction plot de Matlab mais sur Labview. Quelqu'un peut m'aider ?

Voilà ce que j'ai tenté de faire dans un premier temps pour afficher mes cercles dans un graph ( en PJ):
(le but final étant de relier mes cercles à la place de sub_ed2)
en PJ, il y a aussi l'affichage de mes cercles avec la fonction plot de Matlab

Matlab plot figure in Labview

Is there a way to directly display a Matlab plot figure within the front panel of a VI? I know one option is to save the plot as a .jpg or a 2D image array. Is there a way I can have the created plot figure be displayed in an image box within the vi front panel instead of as a separate matlab figure.
Hoping to avoid re-engineering the figures using the Labview plot options.

Art,
If you are reading data returned from matlab, why not use some of the LabVIEW plots to display that data on its front panel? Do you necesarly want to see matlab's plot?
The ways to display actual matlab plot on a front panel, would be either as an image (which seems you are trying to avoid) or if matlab has an activeX control for plot, then in the activeX container.

Why does LabVIEW 2009 revert to the old icon editor?

Hi,
I have noticed that sometimes when I am trying to edit the icon in LabVIEW 2009, I get the old style icon editor from LabVIEW 8.5 days instead of the more advanced new one with layers, gliphys, etc. Once the old style editor shows up, there doesn't seem to be a way to go back to the advanced editor. Has anyone seen this behaviour? I have version 8.5 of LabVIEW still installed, should I remove it? Do I need to restart my computer?
Thanks.
Bob

"Small Font" in LabVIEW 2013/2012 Icon Editor

Dear All:
I have encountered a strange thing recently while using icon editor in LabVIEW 2012 and 2013. I am accustomed to using "Small Font" when editting VI's icon in the Icon editor(LabVIEW 8.0,8.2,8.6,2011), but i found this font in LabVIEW 2012/2013 is different from the one in LabVIEW2011(or 8.6..), the details are as attached images. My question is how can I do to use "Small Font" as I did in LabVIEW 2011, and how to remove the color layers while editting text. any help will be great appreciated. Thanks very much. Hope your reply……

Then do the settings, choose right FONT (Small) and Font size (8 or 9)...!! By doing any changes in the settings, it will not modify any existing text..!!
But after making the changes in the Font setting, next time when you'll try to write any text, either on any of the four lines or by using the text tool, you'll see the text with changed font settings.
I am not allergic to Kudos, in fact I love Kudos.

How can I increase line width on polar plot?

The lines plotted on a LabVIEW 6 polar plot (picture control) are very thin and do not show up well when printed. I would like to increase the line thickness (as can be done easily on the graph controls), but looking through the polar plot VIs, I cannot find any obvious way of doing this.

The polar plots basically use the picture control to draw the lines on a plot. To increase the thickness of the lines you would have to draw another line right next to the line. I'm sure this could be done, but would require alot of messing about with the drawing subVI's to draw all lines in duplicate.
Alternatively you could plot the graph twice, but the second plot has an origin 1 pixel out. This will double the thickness on the screen, but i dont know what it will print out like. See attached example in LV 6.0.
Another thing to try is change the plot colours. You can make the gridlines black (instead of grey), and paint the background white. This makes the lines show up much better. I will also include this in the same example.
I hop
e this helps you..

How do you add a third party sensor to LabVIEW for Lego Mindstorms?

I recently purchased an IR Sensor from Mindsensors (DIST-Nx-Long-v3) which I need for a SLAM (Simultaneous Localization and Mapping Application) that I am developing using the LabVIEW for Lego Mindstorms software. I installed the Mindsonsors IR Sensor, and it works under NXT-G and RobotC, but am having trouble finding a way to get LabVIEW for Lego Mindstorms to install the sensor.
The Mindsensors website gives the following instructions for installing the IR Sensor:
1.Unzip the folder mindsensors.com LVEE
2.Open a blank vi in LVEE
3.On the Block Diagram Go to Tools->Advanced->Edit Palette Set...
Unfortunately, on the Block Diagram of the LabVIEW for Lego Mindstorms, there is no "Advanced->Edict Palette Set" under Tools.
As an alternative, I consulted the documentation that came with LabVIEW for Lego Mindstorms. The Schematic Editor of LabVIEW for Lego Mindstorms lists several sensors, i.e. the Lego Mindstorms sensors and several Hi-Teach (HT) sensors, but there are no procedures listed in the documentation for adding other third party sensors to the Functions Palette.
So, how does one go about adding a third party sensor to LabVIEW for Lego Mindstorms?

Hi Ethan,
As you can see from my Word document, I am a little light on the proper terminology. That's because LVLM comes with inadequate documentation.
I have already followed your recommended protocol for installing a 3rd party sensor (in fact, its the protocol recommended by Mindsensors) with the application set in the Remote Mode (.lvrbt), and it does create a sub-palette with all the Mindsensors functions on it. But when I drag the Mindsensors icon to the Block Diagram and select "Distance Sensor," the Distance Sensor (an IR sensor) doesn't work (even though the Mindsensor's Distance Sensor does work with NXT-G, RobotC and LVLM under other circumstances (see below)).
If I repeat the above process with the application set in the Direct Mode (.vi), I also get the sub-palette with all the Mindsensors functions on it. When I drag the Mindsensors icon to the Block Diagram and select "Distance Sensor," the Distance Sensor does work.
What I need for my mapping application is for the Distance Sensor to work in the Remote Mode. I called NI tech support and the first engineer told me to simple drag the Mindsensors Functions (.vi) onto the Block Diagram. I did this, but when I selected the Distance Sensor, the icon appeared, but the sensor did not work. Since I have no idea what's under the hood of the vi or a function, I assumed that simply dragging the vi/function onto the desktop didn't install the vi/function properly. I went back to the Applications Engineer, and he confessed that he did not understand the LVLM product.
My frustration is being punted to new people, none of whom so far (other than you, of course) understand LVLM.
