• Draw two graphs, a simple graph

  Hello.  This is my first time using the command and the simulation.  I want to draw two graphs in one graph.  It seems that I have to use together and to build tables functions but I don't know how to draw them.  The points x and y (2) are only defined by a single set of points included in the defined table.  The points x and y (1) are the results of another formula, but the two parcels would fit in the same location in a single chart.  I hope that my question is understandable.  I attach a portion of the model I want to be plotted.

  Thank you

  Hello

  You can try something like that. Check the attached VI.

  Kind regards

• Two graphs, one connection

  Hello everyone!

  I suspect that the answer to this question is, but I'm asking anyway.

  As you can see in this extremely simplified VI, I have a tab with two pages control. On page 1, I have a graph and a few controls. So, here's the question...

  I need this exact configuration on page 2. What I have, it's like a mirror of each. If I insert data into the connection of graphs, I would like to show him

  the two graphs. However... I want only one connector. I don't want a connector for each indicator/control. I want a connector for both graphics and

  a connector for each pair of control. I could create a sub vi and use under panels, but I'm curious to know if this is possible.

  I hesitate when I'm trying to explain something, then you can even do not understand what I'm asking.

  Thank you!

  

  Do you mean you want a subset of controls/indicators on all pages of your tab control (or at least will be displayed).  One option is to move the controls in the tab control by using the arrows instead of drag and drop.  I assemble outside of the tab control, group them all selected, and use the arrow keys to move in position on the control tab.  You will see a shadow (slightly inconvenient) editing mode, which indicates that they are floating, but in Run mode, it seems normal.

  Alternatively, I completely missed what you are shooting.

• Align the two graphs

  I have two Cartesian graphs, one under the other, and I want to align their vertical axes. Currently, this happens that the axis each tick labels may have different widths.

  For anyone interested, I realized that you can set the "binding" left the two graphs have the same width and the diagrams themselves to have the same width and they will be aligned.

• (Multi ^ n) draw graphs of waveform

  I'm using LabView 8.2 and I need a graph of waveforms non-sinusoidales twenty bunk on this one (actually two waveforms taken ten times each, so - what counts, but no, I can't just average to them).  With the help of table build to make a standard multiplot with Express waveform graph does not, however, apparently because the VI express can handle only two waveforms at the same time.

  Suggestions?

  Hi DJDDA,

  right click on "table of generation" before the chart and select "concatenate entries.

• I have 2 sets of two xy graphs, I would have both appear on only two graphs (as opposed to four)

  I have a program that runs a set of parameters once forwards and graphical results on the graph 'A' and then performs the same settings, but back and graphics of these results on the chart "B". The graphics are in the loop 'For' so that they have a hard time with the other wire communication. I would like to as the two sets of coordinates to display on a graph

  If you would be re-architecture of your code as a state machine, it should be only a single loop. Try it.

  (Hurries are the loops? Do you need to be able to watch itereactively as graphics build or is it enough to chart all at once at the end?)

  In addition, why are you doing all these successive writing for file operations? You cannot concatenate the strings and add to the queue in a single operation?

• find points of overlap between two graphs

  Hello.

  I would like to find points of overlay on my chart.

  I am simulating sinuses, and I have sampled sine of my instrument.

  On the graph, I see overlay points, which are not exactly the same, with some tolerance.

  I want to it marked on the chart. Is this possible?

  Or simply to store these equal (with a tolerance) samples in the table?

  I tried to use compare with tolerance, but without success.

  Best regards

  Kristina,

  If you are just interested in finding the points that correspond, simply compare the two VI as indicated below.

  Hi, Augustine,.

  Get the data in table form the XY graph using the property node and convert that chain of worksheet and then write to a text file.

  The image attached can be useful for you.

• Using Labview and PXI-4461, how can I AO0 output Signal Square and AO1 output waveform

  I am using PXI-4461 and Labview, boredom, generating 2 signals simultaneously.

  How can I get AO0 out square and exit AO1 SignWave?

  Help, please. (The example Code would be nice)

  Thank you.

  Create two signals and make a table with them.  Use DAQmx Create Virtual Channel to create two channels.  First waveform will be sent to the first string, second waveform on the second channel.

  I understand not all as calendar, clock frequency, amplitude, trigger and other parameters.  You can add these things.  This is just a basic example.

  

• Put multiple graphs of waveforms in a report

  I am a new user of LabView and I am trying to select more then a graph of a waveform with a control or a list to my report of Word, but I couldn't find a way to do it. I can choose ONE of many graphics, but sometimes I need to send two or three.

  My .vi sending so that you guys understand my problem.

  Right click on the table of Boolean block diagram > change in control. You now have a table on your control panel, resize to the size you need. Then, you can double-click on the empty space of front panel to create a label for it. I don't think you can change the actual label on the table without any labels, so I just made an additional label on the side of it.

  

• Registers at offset and graph of waveform for function tare - strain readings

  Hello users,.

  My goal is to put a strain given to zero when the strain has an initial reading. I guess that it will provide records shift in combination with the structure of the case. I tried to use two waveform graphs - showing the offset of the strain and the other showing the strain calibrated, so it will be clearer to see the stabilized strain before the reset button is set to force the strain in the calibrated chart to start from scratch. Is it possible to do?

  Kind regards

  Helen

  Helen, you need not cross-post the question in several boards of Directors. It is a question of LabVIEW and LabVIEW, fortunately, is one of the most active panels.

  So, it looks that you want to have a zero cases that calibrates your strain of reading that would be offset by reading than zero cases. Otherwise, you want to be continuous playback using the zero defined previously.

  A simple solution for this is to put just a case structure within your loop of producer that is activated with a single button "channel zero". When this button is pressed, it takes the last points of data that have been read and creates a lag, so that the new data are now scaling as it.

  How is this look:

  

  If you plan to increase the size of this application, you should watch State Machine architecture or the messages in queue manager if you have a lot of data processing. This structure unique case for zero setting can only get you so far until it's hand.

• Data for the graph economy waveform

  Hello

  I'm trying to collect the data of temperature with the attached VI. Everything works fine until I open the exported file that contains only the last point of the chart. I already had this problem and I think that it is quite common, but I can't find how to solve it.

  Thank you very much for your help!

  Here's what you do.  The central loop is where you get several waveforms.  You want to write each waveform in the output file, which means you want the wave form to write to the worksheet in the Central loop.  Look at its inputs and outputs - put three of them, the file Path/New path, add to the file? and the header? on the shift registers.  Initialize (wants to say wire the register shift outside the While loop) the path of the file to "data\test" (as you've already done), with the new path towards the "output" Shift Register Terminal.  False (the default) of thread to add to the file? and true (if you want headers) to headers?  On the side of the "output" of these two SHIFT registers, wire to 'Add to the file?' "True" and "False" to "Headers?

  For the first time you run the intermediate loop, the file will be opened in a new file (since add to the file? is false) and a possibly written header.  All subsequent calls will add data in the same file (because you wired "True" to add to the file on the output terminal) and no header.

  And to get rid of the unnecessary frame at the end – data flow will be responsible for sequencing.

• Determine the position of a part of the signal on a graph

  Hi all

  I have a problem. I determine the position of a part of the signal on a chart. So, I have to determine the maximum value of the part (this is not a problem).

  Signal a lot of noise. I did some filtration but still signal have noise. Concerning this, filter change signal, two later when I take one measure, there is a possibility that this is not true.

  Anyone has idea how to determine the position of a part of a signal automatically, for the various signals (similar).

  There are photos attached where is what belongs to an interest in a signal. There is a VI where is an a test signal.

  Thank you

  Hello

  From the screenshot, I understand that you only interested in the local maximum of the signal.

  There is a VI that detects peaks when you specify a certaing point and this point maximum width.

  Later, it's just a matter of setting the value of local maximum of you. Basically, you'll have to point once again got 1 d table than VI.

  I enclose a VI that can be a good starting point for your application.

• How to write graph of waveform data to text file with the option to the user to do

  So, I'm new to labview and will have bad to write a program in particular.  I have a waveform graph that runs for 120 seconds, generating a sine curve.  I am, however, having a time difficult get the program to write the x and are coordinated in a text file.  I've attached what I have so far.

  The first task I was assigned was to write a program that creates a curve of snusoidal on the front panel by adding a data point every half second for 120 seconds.  The plot should starts only if the user presses a button to start.

  The next part is to give the user an option to write the data generated in a file of worksheet called 'sine.txt '.  The file name and location should be hard-coded.  The file must contain the x and there contact information of each data point in columns separated by tabs, also known as the delimited.

  I spent several hours refining the attached program, and I can't seem to make it work right.  Any suggestions would be helpful at this stage.

  Sincerely,

  A student of chemistry frustrated whose research mentor is out of town

  First, you create files Excel.  You create text files.  And it seems that your writing on a file already created X (time) vs Y (curve of data) that is delimited by tabs.

  All you do is simply too complicated or a Rube Goldberg.

  All you need is the joint.

• How can I view graph of waveform in a secondary Vi model.

  Hi all

  I am new to Labview so need help. I am developing an application that reads data from a network of sensors (WSN) wireless. The WSN composed of connected to the USB base station what data gets other nodes of sensors.  The data comes in a certain format.  Name of the node, temperature and humidity reading etc. I want to read data from the serial port, and based on the node name, I want to view information for each node in the separate window s or secondary etc. So if a new node is detected then a new window is created for this node. Given that all nodes have the same sensors on board I only need a model one. I can read the data by using the serial port, analyze the data to detect which node it is and also what are the sensor readings. I created a template of VI for the sensor node. I have problems showing model screw in a secondary school. I can correctly display a waveform graph in high school, but I have problems in a waveform graph display in the secondary. I can see the actual waveform table in high school, but I do not see the plot. Would be grateful if someone could tell what I'm doing wrong here.

  Thank you very much

  Hi all

  I think I solved the problem. It seems that I was running the Vi in a loop. I took the Vi run outside the time lopp and it works very well. Also, I need to close the reference at the end.
