• Tracker mouse crosshair on the graphics path

  Hi all

  I set up a flex route chart, which works very well (able to draw points to it).  I want to add a location-based focus that moves with the mouse.  The reticle will draw a horizontal and vertical line crossing just to the pointer of the mouse on the edges of the table.  I am already registered for the event of moving the mouse (I have a status line that prints the values of the real world based on x and position y of the mouse moves).  Implementing cross-shaped, I tried to implement causes the mouse tracking act very strange... almost, in a delay type behavior.  I use a Graphics the graphics path object object.  I'm doing clearly every time before I redraw the viewfinder (as the mouse moves).  'Clair' seems to be the heart of the problem of lag (if I comment on the 'clear', the follow-up works fine...) "but of course does not erase the viewfinder of the previous mouse position).  I saw a guy 'xor' function that I used on as projects before. Any ideas or suggestions would be greatly appreciated.

• How to force the colors of graphics path of waveform?

  Hello

  I have a problem forcing my WaveformGraphs to have colours in the specific field. I changed the properties several times: he returned to another color when I restart. I tried the Plot color with active Plot property node: it says it can not work (maybe I didn't do it well). I did the graphics of type defs, changed their properties, it is their default value and then saved. I need the 3 graphs have the same colors of conspiracy because they are related.

  Do you have any tips for me?

  Here's a way to do it. This will outline the first 4 colors in each graph plot.

  (Get the references of your chart and put them in a table for the entry.)

• How to convert a single scalar value in a table for the graphics path

  I try to establish a curve of output power of power factor vs. But my power factor shows a single scalar value (DBL) and power output is table 1 d of scalars. suggest me a way to trace "output power (Pout) vs power factor".

  It will be a really boring plot (a single line with any power factor you have), but you can use the table to initialize with the size of the switchboard.

• How to reset the graphics path properties

  Hello

  When a Labview graph is populated by the data for the first time, the plot attributes (color, style of line,...) are generated automatically by Labview.

  Imagine that the user changes the way the plot resembles his own taste. Let's say the plot 0 was blue and it's Green.

  Now it loads a new set of data in the graph, the color of the field 0 is always green.

  I wish that Labview to reassign some random colors for the plots as he did when given here where it is loaded in the chart for the first time.

  How can I do?

  Best regards

  Like any other control in LabVIEW, the properties that you manually change to stick around. Now, you can have your land constitute up to be the default colors and attributes, and it will load this way whenever the VI loads. If you pull the initial attributes when the first load of your VI, you can then use these reset all programmatically when you want.

• How can I paste a picture (graphics path) in excel?

  I use the Builder took the kit to the data I want and where I want to a specific excel file.  However, I would also like to import the image of a band chart as well.  I figured out how to export to the clip board, but I don't know how to paste into excel.  Any ideas?

  Hi Brad,

  You can have the best chance to post in the forum LabVIEW.

  If you save the image to a temporary file, you could then import it into the report:

  

• Adding 3D graphics path

  Hello

  I use the ActiveX tracking feature to display a time vs. frequency Impedance vs 3D illustration. Everything works fine. Now, I want to add a second story to the same graph without removing the first. I have read and tried everything / topic in this forum already, but I just cannot persuade CVI :-( I use the Plots3DAdd command to do this. Each simple concession PLOT1 & PLOT2 works if I comment the other. But together I always make a positve return value (0) for Plots3DAdd, but a negative one (-274...) for the second command in Plot3DSurface.

  The interesting part of my code is:

  // 1-dimensional arrys xVt, yVt, 2-dimensional zVt
  
  GetObjHandleFromActiveXCtrl(panelHandle, PANEL_GRAPH3D, &graphHandle);CW3DGraphLib__DCWGraph3DGetPlots(graphHandle, NULL, &plotsHandle);CW3DGraphLib_CWPlots3DItem(plotsHandle, NULL, CA_VariantInt(1),&plotHandle);
  
  // PLOT1CW3DGraphLib_CWPlot3DPlot3DSurface(plotHandle,NULL,xVt,Test,zVt,CA_DEFAULT_VAL);
  
  // Add a 2nd plot  retval=CW3DGraphLib_CWPlots3DAdd(plotsHandle,NULL,¤tPlot);
  
  // PLOT2retval=CW3DGraphLib_CWPlot3DPlot3DSurface(currentPlot,NULL,xVt,yVt,zVt,CA_DEFAULT_VAL);
  

  It will soon be mad me because this problem occupies me 3 days. I'd appreciate any help or advice!

  Thanks for reading!

  Hi Michael,

  I think you were pretty close. I've attached an example of how use several plots in the graph 1. I think you should call the function Add first before actually draw you something.

  I hope this helps!

• Create a graphical path of text file

  I have a research project where I need to superimpose a chart of scrolling representative vibrato (sine wave as the fundamental frequency changes) of violin performance.

  The video below was made some years ago - overlay was done manually by the chart plotted by frequency of screenshot analysis program. It was a lot of work because the program could not trace the entire graph of a sudden and I had to capture multiple screens and collect them before importing to AE.

  The program can display data from text of time / frequency in one shot (see below), and I'm hoping to turn that plot data in a chart in AE, possibly using effect of outline or something.

  I'm trying to find me an answer, but in the meantime I am also asking gurus for any suggestions/pointers.

  Thanks in advance for any help.

  You can use the effect drawn or a particle system that injects a particle for each sample or any other method you may fancy, which renders a dot or partial stroke dynamically. And you wouldn't necessarily use a huge solid. You simply let the scroll of graph by using the built-in options of effects like management to show additional effects as movement tile or transformation. You really need to think differently here. It is a view, not a tool of analysis.

• How to draw 3D graphics

  Hello:

  Is there a way of using VS 8.0 under VB2005 3D graphics path?

  I want to get something like this:

  

  It's happened to the best of us

  In fact, the example showed a 2D, not 3D.

  Just calculate the Spectra by block, clone the first diagram of dispersion and draw the spectra with a small bias to have the 3d aspect.

  Thanks anyway.

• Problems with joining paths

  Could someone please explain why I often get an error message when I try to join two lines? I can't reproduce the error now, but I found the message more to stackexchange:

  "To register, you must select two open end points. If they are not on the same path, they can be on any text within graphics paths, and if two of them are grouped together, they must be in the same group. »

  Or maybe someone could translate the message in English?

  Thank you for your reply Jacob, but I always if sure I select only two anchor points.

  And I got a different error message earlier, saying that the selected objects cannot be joined because they are invalid objects (transparent traces, text, graphic objects, live paint group). So, there seems to be many cases where the function works everything simply.

  EDIT: I've found a workaround: when the paths cannot be joined because they have a live paint group, this group can be expanded. This closes the gaps that cannot otherwise be closed.

• Cannot reconnect my Smartphone using Bluetooth

  Hello world

  I have connected my Samsung Galaxy android for my Toshiba Satellite (windows 7) via Bluetooth to receive GPS data to use on my graphics path program.

  Easy to do, BUT if I disconnect the device and then try to connect again, BT Stack will not reconnect. While trying to reconnect, there is no request to for passkey and I guess that's maybe part of the problem.

  I installed the last BT V 8 stack, but this does not resolve the issue. Please help before I go crazy.

  Sincere greetings
  Michael Barrett

  Hello

  Have you tried to use the secret key Fn + F8 to disable and then enable the BT after the smartphone has been disconnected?

• Fade colors in the graph of the intensity

  Hello world

  I did a program where I read a 2D array and draw this picture in a graph of intensity.

  I was wondering if the colors in the chart weaken each other, preferably in a vertical position (columns). The idea is that digital data becomes viewed as a genetic profile.

  I added a picture of the graphics path.

  Thank you.

  Without manipulating the table, no it's not possible.  I had an idea about the exchange of idea to solve this problem, I recommend that vote you for it.  Anti-aliasing or smooth intensity plot

  As says the idea, see this post for workarounds.

• Several DLL thread with a GUI

  I would like to create a DLL that is called within a c program.  The DLL would show a GUI that is updated when the C program passes 5 values.  The DLL would receive the values once every 0.1 s and update accordingly.  I wanted to use CVI, because as I understand it, I can create a GUI with CVI.  Mainly, the GUI requires no user interactation.  It displays only one card.

  1. the machine - what is using that program c with the DLL is in need of any kind of runtime or software installed?  If so, is there another way to solve this problem?  I don't want to install a bunch of stuff in a workstation before the DLL can be used.  If the DLL is used, I installed on the test station 60, which is not desirable.

  2. when the DLL is called (once every ~ 0.1 s), it must take place in another thread, so that the main program of C does not slow down the speed.  Is this possible?

  3 can I still update once every 0.1 s or faster?

  Hello

  (1) application of CVI need its duration, oficialy:runtime must be installed.

  There are also ' unoficial/supported no' way to do it. Just create the installer for your application of CVI IDE and select "install the runtime to the directory of the application. Then install this to any PC. You will get run-time CVI (GUI) library at this location. And (if you're a lucky - remember that it is an unsupported action) you can just copy this folder requests to any PC.

  (2) I think that 'yes '. ICB has good support for multithreading, just spawn a thread and execute the RunUserInterface() function, then you can use the function such as PostDefferedCall() or PostDefferedCallToThread(), you can also use something like "thread safe queue" (glance at help for the function CmtNewTSQ)

  (3) he has no problem with calling more frequently, especially with TSQ (ThreadSafeQueue).

  You can simply feed TSQ at very fast speed, because it don't have to redraw immediately.

  Then in the thread, you can get data of TSQ with independent rate for drawing (0.1 s or more) and process all of the incoming data as you want (graphics path or not). Beter reaction, you can set up a callback TSQ (CmtInstallTSQCallback), which will be called when there is some data in it (configurable).

• Problems of acquisition & visualization: fails at 100 Hz, OK more low or more freqs

  Hi all

  I have some data acquisition & visualitzating problems.

  The acquired data is a voltage (0 - 10V) from RDP LVDT & conditioner. My pourpose is simple: I want to gain everything by visualizing and recording to disk. I use a card BNC-2101 & 6062E. I also use LabView 8.5 on Windows XP s.p.3. I tried three ways: my own .vi and examples of LabView with internal clock and the external clock. They all consist of two steps: aquire, visualize data on a graph. and my own .vi also saves the data in a .lvm.

  On the first try, I was able to acquire data with sample on request mode. But I want to get to a known frequency, so I put 1-sample (controlled HW). I set the frequency and the number of samples as well as the number of samples is of approximately 1/5 of the frequency, for a rate of graphics path 5 times / sec., BUT I found the following problems:

  (1) for the acquisition in the low frequencies, say 50 Hz, there is a large gap between read data a shown in the data graphic: from 2 to 8 seconds.

  (2) for the acquisition to high and very high frequencies, say 20 kHz to 100 kHz, the graphic works OK. But in this way, the file I'm writing is too much. I don't understand why when I put the computer work harder, with more data, it appears without delay.

  (3) for the acquisition to 100 Hz, it does not work. An error (just know don't remember the #, is one who says this time-out has been reached whithout having given to read aviable). 99.9 Hz works, but not at 100 Hz or 200 Hz.  I really don't understand this point.

  Can someone help me please?

  Thank you for your attention,

  usuario

  Just writing to tell you that we have tried with another computer and had no problems with the hardware and the same .vi.

  And have had no problem for the las 2 months.

  Thank you all for your dedication.
