Front panel graph with selectable points

I don't if this can be done, but I was wondering if I can have a graph in the front panel that would graph only the points I select. This is the situation: I'm taking measurements in the program and I want to make a graph with them. The thing is that a don't want a graph with lots of points, I just want to select a point and graph it. When I want to, I select to take a point and graph it, then I'll change the independent variable and then select again one point and graph it, showing a curve of what I have, and so on. I know that for this maybe I'll need to store those single points with an array or something. If anyone can help me, please do so. Thank you.

The data you acquire is received in array form and based on the sample size, you should be able to determine the number of points in the array. Then simply decide which points you want and put them into a second array and plot that array.

Can I fit an equation to points entered on a front panel graph?

I'm trying to create a VI to control a syringe pump using Labview 7.0. I was hoping to be able to input points on a front panel graph (using the curser), have labview fit the points to a curve and control the syringe pump to achieve the desired pH profile. Is it possible to use the curser to input data points from the front panel?

Yes, one way you can do this is using various property nodes.
Attached is a LV 6.1 Example (fine for LV 7, of course).

How can i use the same front panel graph in more than one events in an event structure?

i want to display the signals from my sensorDAQ in a graph.but i have more than one event in the event structure to acquire the signal and display it in the graph.the first event is to acquire the threshold signals and its displayed in the graph as a feedback.after the first event is executed, i will call the second event,where the further signals are acuired and compared with the threshold signals from the event 1.my question is how can i use the same front panel control in more than two events in the event structure?please answer me i'm stuck.
Solved!

Hi,
I have attached here an example of doing the same using shift registers and local variables. Take a look. Shift register is always a better option than local variables.

No sound front panel audio with newest CMI 9880L driver

So basically I plugged in a headphone the other day on the front panel and noticed the audio jack randomly stopped working. They worked for about 3 years and the last changes I've made was updating the CMI 9880L driver to the newest one on the MSI website for my mainboard( 915P combo), about a month ago. So I thought the problem was the new driver, I went back to the CD that came with the board and installed the audio drivers I had before, It also didnt work!. I went to the hardware manager and clicked on the ROLL BACK driver button and it installed a microsoft driver, this time the front audio jacks DID work, this means is not a hardware problem. What is going on with the new C-MEDIA driver? what should I do to restore sound to the front jacks?
ps. I messed around with the BIOS options(switching between Azalia and AC97) and nothing happened.

I am quite confused... would appreciate your help.
Well, so was I. A good explanation can be found at
http://www.intel.com/support/motherboards/desktop/sb/cs-015851.htm
The point is, that the same output can be used either for AC-97 front panel audio (what you have on your chassis) or for High Definition Audio (which I've never seen). The board seems to differentiate between these two by means of the PIN #4 (Presence), which you just leave disconnected in your case.
Microphone should use PINs 1, 2 and 3:
1 - Mic In, 2 - Ground, 3 - Mic Power
Audio output should use PINs 5, 6, 9 and 10:
5 - R-Out, 6 - R-RET, 9 - L-Out, 10 - L-RET.
After you'll have connected the PINs to the audio connectors, do not forget to turn off the jack detection in the "Realtek HD Audio Manager" as I described before.

Using Front Panel Audio with Fatality Professional

I have a query regarding connections on the Titanium Fatality PCIe.
I have an XFi XtremeMusic PCI card and am considering replacing it with the Titanium Fatality XFi card. A couple of reasons, I like the shrouded enclosure, I like the little XFi LED logo, I want to move away from PCI cards in my system.
But one of the main reasons is to allow me to connect my Intel HD Audio connector to the card so I can use the Headphone/Mic socket on my case. So if anyone has these cards can they confirm that they have an Intel HD Audio connector on them. If so does connecting the headphone to the case socket mute the speakers?
Cheers

Well, I don't personally have one, but I was under the impression that every X-Fi had one. I know my X-Fi Fatal1ty (original PCI version) included it, and my Recon3D definitely does.
Plus if you check their shop website for the Titanium Fatal1ty Professional than the specs page lists a 2x 5-pin connector for "Intel HD Audio Compatible Front Panel Header" so it most likely does.
I would assume it would mute the speakers only if your case is fully Azalia compliant. By that, I mean the standard (as dictated by Intel) involves the use of two normally-open switches - one each on the headphone and microphone jack - which are closed as a result of plugging something into them. Some cases have these jacks which means it can detect when you plug something in and respond accordingly, but others use cheaper (we're talking differences in cents - not exactly substantial savings, but when you do it thousands of times over it adds up) switchless jacks and simply report them as always plugged in.
Just remember to set up the X-Fi panels to mute the speakers when you plug headphones in, as well as switch the output to headphone mode. You can actually set those two options separately on X-Fis.

Why does my Web Publishing Tool fail to create an image of my front panel when I select the "Embedded" viewing mode?

I am trying to create an html file for access by a client computer through the LabVIEW Web Server. I want to enable the client to control the vi, so am chosing "Embedded" for the Viewing Option in the Web Publishing Tool. The small preview screen in the Web Publishing Tool shows an image of my front panel, but the resulting html file does not include this image. The Web Server error log shows a 404 error which I believe is due to the lack of an image (or any front panel objects) present in the html file: Error: 404 "Not Found" for "/.lv_frontpanelprotocol.rpvi100", file "c:/program files/national instruments/labview 2010/www/.lv_frontpanelprotocol.rpvi100": Can't access URL
If you are aware of this problem or know any solutions, please post a reply.
Thanks,
David

Does it work if you preview the web page locally?
Does the client computer have at least the minimum 2010 run time engine installed?

Front panel Printing with A4 Standerd

Easy printing the test reports with the Front panel as per the A4 Standard.
For making the A4 Standard printing needs the option to make Pane A4 Size.
Then we can make easily create the front panel reports easy manner, add Indicator (result ,title, logo, auto signatures etc) in the report and generate the print out.

Developing a GUI on a computer monitor is that much different from printing an A4 (or letter for those americans insisting to use this peculiar standard ), that I think there are not many use cases to force it to the size of a piece of paper.
Alternatively, one could define a printing area, optionally being visible on the front panel and being able to print just that area. So put all controls and indicators you want to be printed in that area, leaving space for GUI elements you don't want to be printed.
The more I think of this the more I like it.
So, on second thought, kudos but preferably for a printing area to be defined by the user.
Greetings from the Netherlands where printers loaded with A4 paper are as common as water runnning from the tap.
(and yes, we all do have taps here ).

NI IVI Soft front panel compatibility with IVI-COM drivers

Does IVI soft front panels support IVI-COM instruments drivers ?
For example, I would like to use IVI-COM driver for Tektronix TDS5000 with TestStand...

├ CTD - Certified TestStand Developer (2004 & 2007)

The IVI soft front panels that ship with the NI IVI Driver Toolset do not support calling IVI-COM drivers. The soft front panels support IVI-C drivers. On Instrument Driver Network there are IVI-C drivers for other Tektronix scopes.

Front panel locks with event structure loop and another while loop

Hi,
Why is the front panel locking after changing the value of the "boolean switch" twice? This problem disappears if I uncheck the "lock front panel" option in the event case. However I don't understand why that is the case since the event structure loop has already finished executing.
thanks

Do you really want the event handling to stop after detecting the first event? If so then as Christian says the event structure will cause the front panel to lock. What you can do is dynamically register and unregister the events. You right click on the event structure and enable "Show Dynamic Event Terminals" Then you can programatically register and unregister events.
Here is your vi modified to do that.
Edit: Just in case - right click on the control and create a reference. When selecting the source of the event in the structure look under the dynamic section.

Front Panel Connectors with new Motherboard

Hello Lenovo Community, i have just purchased a new mother board(msi h55 e23) and have just installed it into my Lenovo 3000 h210. The only problem with it is the front panel connectors. I don't understand how they're supposed to work. I have a JFP1 and JFP2, yet i'm not sure where the front panel connectors go because im pretty sure they aren't your standard front panel connectors. Is there anyway to get by this without me having to purchase a new case?

P35 Platinum front panel audio with Antec P180 case?

God I have a headache after reading all those "front panel audio" threads. Why can't mb's all use the same freaking pinouts!!!!
The case doesn't have a HD front panel.
MB pinouts are:
1. Mic_L (MIC Left Channel)
2. GND
3. MIC_R (MIC Right Channel)
4. PRESENCE#
5. LINEout_R (analog port right channel)
6. MIC_JD (MIC jack detect)
7. Front_JD
8. NC (empty)
9. LINEout_L (analog port left channel)
10. LINEout_JD
Case Front Panel connector is a preconfigured block with pigtails hanging off in case it doesn't match up.
1. MIC Signal
2. MIC Power (MIC BIAS)
3. Ground
4. FPOUT-R (front right)
5. FPOUT-L (front left)
6. RET-R (rear right)
7. RET-R (rear left)
glaring differences are the ground and the MIC connectors.
How do I connect these? I don't want to fry anything.
Thanks.

They do have the same pinouts. There are two standards is the reason for two different pinouts. It's just that your MB is Intel HD and your case is AC-97.
For Intel® High Definition Front Panel Audio
Pin Signal Name Description
1 PORT 1L Analog Port 1 - left channel (Microphone)
2 GND Ground
3 PORT 1R Analog Port 1 - right channel (Microphone)
4 PRESENCE# Active low signal that signals BIOS that an Intel® HD Audio dongle is connected to the analog header. PRESENCE# = 0 when an Intel® HD Audio dongle is connected
5 PORT 2R Analog Port 2 - right channel (Headphone)
6 SENSE1_RETURN Jack detection return for front panel (JACK1)
7 SENSE_SEND Jack detection sense line from the Intel® HD Audio CODEC jack detection resistor network
8 KEY Connector key
9 PORT 2L Analog Port 2 - left channel (Headphone)
10 SENSE2_RETURN Jack detection return for front panel (JACK2)
For AC-97 Front Panel Audio
Pin Signal Name Description
1 MIC Front panel microphone input signal (biased when supporting stereo microphone)
2 AUD_GND Ground used by analog
3 MIC_BIAS Microphone power / additional MIC input for stereo microphone support
4 AUD_GND Ground used by analog audio circuits
5 FP_OUT_R Right channel audio signal to front panel (headphone drive capable)
6 FP_RETURN_R Right channel audio signal return from front panel (when headphones unplugged)
7 AUD_5V Filtered +5 V used by analog audio circuits
8 KEY No pin
9 FP_OUT_L Left channel audio signal to front panel (headphone drive capable)
10 FP_RETURN_L Left channel audio signal return from front panel (when headphones unplugged)

Time display on x-axis for front panel instead of data points

What do I need to change or add in my block diagram so that on the waveform graph the time will be on the x-axis instead of the data points. I am running this VI on a pda for some testing and I would rather get the time on the horizontal axis. Im also using an NI USB-6008, windows xp and Labview 8.2
Thanks

And since you are sending it an array of doubles rather than an array of waveforms, there is no timin information associated with it. It will assume 1 sample per second. If your acquisition is faster than that, you will need to set the dT of the graph or the scaling multiplier factor of the X scale of that graph.
(PS, it is always a good programming practice to show the labels for all the terminals on your block diagram and assign the terminal a name.)

LV2011 problem with several front panels

Hello,
There is a bug in my software and I don't know it is common to every one or not. This not to be worry, I will notify you anyway. When I open only one front panel and one block diagram which having a program to communicate with a serial device. In this case, if I choose the VISA resource name, it obviously takes some time to popup the USB and after it show the port and front panel will stay in front you until you choose the device. Here, every thing is fine but when I open several front panels and working on only with serial program front panel to choose the serial device in VISA resource name. Then after some time, it took me to another front panel. I have seen this problem several times in past two months. More, even when I am decorating the front panel and front panel took some time after pushing some controls and switched another front panel.
Is this bug? Or I common for every one.
Using labVIEW 2011.

I am certainly using labVIEW from two months. So, I did not use MAX in my past time. I only used one time to check my USB 6008 device but this is off topic here. I will tell you down here.
Suppose, If I open multiple VI's and I am only working with one VI that can communicate with my SERIAL device and the rest of the VI's(Block diagram and front panel) are rested. This case, if I click the drop downlist of "VISA resource name" of SERIAL VI, then it took some time(200ms or 100 ms, just it is a guess) to populate and it is switched to another front panel which were opened and rested before. Again, I need to come to my serial front panel again to select the COM port. This is one case.
If don't have any other VI's not opened than this serial Vi. Then it stays on the same front panel.
Is this bug came with labVIEW or is it common?

I want to save an image of the front panel, (with data), after every VI run

When I try to copy the front panel (using a select all), and paist to paint, all the data in the graphs show up as they did after the last run, but the data in the charts dissapear. The chart itself is copied but the data is not. Any ideas on how to solve this?
Thanks,
Brian

This Knowledgebase also has some information on programatically saving VI images
http://digital.ni.com/public.nsf/websearch/942DAA35C7B35616862565FE005F713F?OpenDocument
(KB 197BB7VJ if the link doesn't work).
Note that you don't have to put the code in the VI you are running in order to save it to a file, so you don't actually have to modify your VI. You can just run a seperate VI that uses the VI name from the first one (I've attached a VI which could either be run standalone or used as a SubVI, as well as an example of using it as a SubVI).
If you don't want to do it programatically you could just hit the print screen button on your keyboard and then paste it into paint and crop off the extra windows stuff.
