I need autoscaling on a graph XY to ignore a parcel

I'm doing the autoscaling to ignore one of the three locations on a XY Chart.  My program trace a set of data points, that approach and exceed a critical level.  My chart has three parcels: under the limit points are green points, points above the limit are red dots, and the limit is a horizontal dotted line extending between two points.  Initially, endpoints of the line have been established in the vicinity of the x-values of data.  Autoscaling worked very well, of course, but the line analyses as well as the data they are traced.  This limit is a fixed value, I like the line to stretch completely on the screen and stand still.

To this end, I put endpoints beyond the limits of the x values.  Now, auto-scaling of the tracks with the endpoints of the line and the actual data are compacted in the middle of the graph.  Is it possible I can forward the autoscaling only with data points and ignore the line, or is the best option, just write my own code, autoscaling?

Thank you!

You could wirte your own automatic scale, but I think is easier to do something to change your horizontal line of a parcel of a cursor. You can use the list property of cursor or active (the control graph) the cursor property to control positioning and the color of the cursor, and you have not to worry ever its end points (there no).

    Hello!!

    I have attached the solution to your problem.

    It not work because when you scan the point that you use in your second chain makes a mistake (I'm sure you noticed that ).

    In addition, you cannot create 2 plots in the way that you tried, you need a cluster of berries (X & Y) NO 2 bays of clusters, this is the reason, because you could not connect the wire to the XY graph.

  • graph waveform of several sensors

    Hi, I receive data from 50 sensors with a microcontroller. Data from the sensors are stored in LabVIEW in an array of cluster, each cluster containing a unique sensor info. I need to display a graph of trends of the curve of value 3 of all sensors, so that each sensor should be represented by a color. The data are updated every minute. Can someone help me please?

    First of all, I'm sure you want a graphic, not a graphic.  A graph keeps a history.  A chart shows just the last thing you wrote for her.

    Secondly, to make the building of the waveforms within the loop FOR.  Makes things MUCH simpler.

  • Make a graph act as a graphic

    Hi all

    I want a graph that would act as a graphic...

    What I mean is a graph that will update quite the same way as a table (band or scope). Why not simply use graph is because I need annotation of the graph (not availabable with chart) and I have to be able to scroll back and see the complete waveform from the beginning of the acquisition.

    What I tried, it is to use 'Xscale - range - Start' properties and update each time I update my graphic. The problem is that we see this change so that the graphic is flashing (to resume, we see nothing).

    What someone has an idea of how to implement something that would do the trick. I searched around, but without success.

    Thanks in advance!

    Vincent

    I posted an example here. I can't watch it now, but it uses the same basic method that you do (but not with a waveform), and if my memory is not waver.

    In any case, if you want to avoid the flickering, you can try to use the property of the Panel Defer Panel class updates. Set it before writing the value F and T after.

  • The multiplot XY graphs & Data Types

    Currently working on four tracing data sensors of pressure on a XY plot, but up to this impossible. In addition, I do not know if I use the correct data type.

    As you can see in the image below, my code is taking measures of the DAQ Assistant and proceeds to divide the data into four signals before taking their average. My predecessor was thought to build a matrix of these signals of four split with what I suppose is the timestamp. The problem is that only one set of data being plotted right now. I tried to change the order of things that I use a cluster as my data type, but I always feel to get an error.

    Recently I saw this webpage https://decibel.ni.com/content/docs/DOC-5129 for more help, but imitating the way they don't seem to work for my code.

    Can anyone help?

    All I see are 1 d arrays. A matrix in LabVIEW is special data type used for... you guessed it, matrix calculations. Do not use it interchangeably with table.

    The main problem is that you send a single cluster in the XY graph, which means a single parcel. What you want is an array of clusters. The clusters will be a beam of table 1 d of timestamps and D 1 table of measures. But it is the hard way to do it, and this means you need to keep all your data as the tracks of the loop, with a lot of unbundling, build tables and rebundling. Crossrulz wrote a great nugget on How to use a sporadic data graphic , which makes things much easier, because the chart holds the story for you. Take a look at this post, and if you want to have several plots, you can just make a table of the waveforms, as I did below. Where you see the 'random number' dice, you will put your unique measurement data you acquire every time as the iteration of the loop. You can test the program by running and clicking on the Add Point"" button.

  • Make a graph that is customized by using the motion of the instrument and in real time

    I am very new to LabVIEW and I need to make a graph or a table with the data being the movement of a device and the x data in real time.  I know how to get the position of the instrument information and how to put in real time for the x axis, but I have no idea how to wire those things in a graph, what type of graph to use, or what other screws I need for the y - data.  I have attached the page I'm working on that... It's kind of just a meli melo of things I thought that may be useful, but I obviously need help.  Thanks in advance.

    Have you so far in your VI, it seems you will ask some data on the location of your device on each iteration of the loop.  In this case, you can use a waveform diagram in the while loop to display these points.  Each new point will be added to the table as they come.  You can do this by writing values to the table as you reach them inside the while loop.  This link should also be able to clear up some confusion about the differences between the tables and charts in LabVIEW.

  • How to plot graphs with a different number of values

    Hello guys,.

    After a few hours, I have to give up and you ask for help.

    The problem:

    It must be possible to disregard some of the measured values. The measure and valid points should appear in the same graph (for example, the measured values of 'x' and valideded 'o' data. Valideded data would look like a circle with an 'x' in the middle).

    So far so good.

    The time difference between the measured data (dbl-table) is always the same (20-30 seconds).

    I tried (see attachment):

    If the measured value is not valid, I delete this value and change in this case the 'dt' in the waveform (see loop 2), if I get the data I want.

    I tried different ways, but I can't to plot the data in a single chart (I think because the timedifference 'dt' is not the same)

    You have an idea, how can I draw the graphs shown in 'graphic linear adjustment' and 'validated card data' in the same chart?

    Maybe I need to use the "graph" and not "table"?

    I chose graphic because it must be possible to hide/show each plot (but me, I'd work with graph as well)

    I hope I described the problem well and you can help me. I'm sure, it's possible and probably easy, but I'm not

    And here are the columns specified in the control file:

      ...
      ...
      ADDRESS_NUM1,
      ADDRESS_STREET1,
      ADDRESS_ST1,
      ADDRESS_ZIP1,
      ADDRESS_COUNTY1,
      DATE2            DATE "MM/DD/YYYY",
      TM2              DATE "HH:MI AM",
      TZ2,
      ...
      ...
    

    (You can open the csv file in MS Excel to get a better picture of the data in there).

    As seen above, due to the incompatibility, sql * loader loads 'City' in ADDRESS_ST1, 'State' in ADDRESS_ZIP1, "Zip" in ADDRESS_COUNTY1 and DATE2 "County" - where it error.

    The solution would be-

    (a) If you want to load the 'City' information from the data file, and then add the "City" column in the table (if nonexistent) and specify in the control file.

    (b) If you do not want to load the 'City' information from the data file, you can specify a column to 'FILL' in the file of control as follows:

      ...
      ...
      ADDRESS_NUM1,
      ADDRESS_STREET1,
      city1            FILLER,
      ADDRESS_ST1,
      ADDRESS_ZIP1,
      ADDRESS_COUNTY1,
      DATE2            DATE "MM/DD/YYYY",
      TM2              DATE "HH:MI AM",
      TZ2,
      ADDRESS_NUM2,
      ADDRESS_STREET2,
      city2            FILLER,
      ADDRESS_ST2,
      ADDRESS_ZIP2,
      ADDRESS_COUNTY2,
      ...
      ...
    

    Hope that helps,
