XY graph help

I posted a thread similar to all at the time, I had trouble getting 3 parcels on a XY Chart.  I managed to do work and I'm trying to write a similar program, but I'm still on the issues with the graphics features in LabVIEW.

The joint "block XY" is the block diagram with that out, I'm working.

I want the program to do:

Consumers loop will run 3 times, and according to the control of the 'weighting', going to 3 sets of data (weights A, B and C for sound level meters.)  The program does not have the data in the table, he uses a signal generator and voltmeter to collect data, but the data in the table works fine for this work).

Traditionally, all 3 data series are plotted together on the same graphic.

The second attachment, "graph XY 3 plots" is the chart that I am currently getting with the block diagram.

There are 2 problems with the way data are presented in the chart, more important than the other 1.

First, notice how LabVIEW connects the last point 1 chart, with the first point on the other, resulting in 2 straight lines that pass through the center of my table.  This is probably due to the fact that LabVIEW is treat them as 1 set of data instead of 3 separate... which brings me to the next, less important question.

Because LabVIEW treats all as 1 set of data, there is only 1 label "conspiracy 0" in the legend.  It would be nice, although not necessary, if I could have the following 3 items in the legend, one for each plot (and obviously rename, but I know not how to do this).  A, B and C weightings are always the same, so without the caption, you still not know who is who, but it would be nice to have a legend.

  • Deadlock Graph-Help needed

    I'm trying to post this question several times, that the question is automatically deleted, not sure because his envoy on other forums as well.

    I have removed the issue from other groups, in order to avoid duplication of work, which I had posted, and it is the only asset.

    Then I would ask to the administrator of the group do not delete this question without answering.

    Now causes a blocking issue.

    I have a few questions about the same thing:

    • How to find who is the resource involved in the deadlock?
      • I already checked with the command SQL - select object_name, data_object_id from dba_objects where data_object_id = 39341
        • I have no line when I run.
    • The name of the resource, which can be decrypted?

    The inserts are all sorted by the primary key value, but still we end up with blocking. This could be due to the lock on the Unique key constraint

    If so, how do you know if it is a lock acquired on Table - DeviceDetails GOLD on the Unique key of the table DeviceDetails constraint?

    Under what scenarios would serve mode lock "S"? We do not select it for editing anywhere and in any case, this seems to be the command insert according to the chart below.

  • Need help with graph/table

    Heey everybody,

    I am currently using a Spider8 and Labview to get data from the sensors, after I use Labview to process the data in charts or graphs. Alltough I have 2 small problems using a table/chart:

    1: for some graphics I want to use 1 y axis (example: volts or current) and 1 x-axis, time. I want this time to be like clockwork that counts only the seconds (example: 0-100 sec), using absolute time or relative, for formatting is not an option because they rely much too strong/fast. There is an example of this type of charts in the Appendix: measurement of time current vs.

    2: for most of the other tables/graphs I want to use several axis y (example for a motor: current, RPM and torque) and I want to use a category axis that may go 'back' (example for a motor: rotations). There is an example of this type of charts in the Appendix: measurement of torque.

    I have no idea how to make good sense, so your help is welcome

    Thank you!

    Hi grasman,.

    have you read jcarmodys message on how to apply a trace on a scale there?

    See the attachment on how to draw 2 curves on a xy chart and attach each parcel on a scale. I strictly followed the message context help chart and jcarmodys...

    I would also say to stay away from express screws: they tend to make more problems than to provide aid. You are more involved in conversions of type (to/from DDT) - using simple son gives you simply more to control what's happening in your code!

  • Help with multiple locations on a XY graph under certain conditions

    Hi, I have a question about manipulating a XY Chart.

    (1) whenever the plot crosses the x-axis for value go to the top, I want the plot to change color, so that it crosses 0 will go back to the top, and I want that specific portion having a different color. It's really hard to explain, so I'll post a picture:

    [URL =http://img691.imageshack.us/i/xygraphexample.jpg/] [IMG] http://img691.imageshack.us/img691/4540/xygraphexample.jpg [LINE] [URL]

    As you can see, if the graph we cross the x-axis by decreasing, it should not change color. Only increase.

    I can't understand how to do this. I know it will take more than one location, but how would I randomly change the color as well as detect if its path that goes to the top or not.

    Any help would be appreciated.

    Thank you

    OK - chance I'm not too busy today...

    Usually, I use either screw express, but was looking for a quick solution for you.

    Here's the sample made with only the basic trigger function - no express VI.

    Also added a selectable threshold by the user.

    Then, on the space between the plots, if there is no data in the original, there no data in the colors either.

  • With the help of the graph of the intensity

    Hello

    Currently, I have a problem with the graphics of the intensity. I use the Toolbox of the time frequency in Labview. Currently, I am having a problem where I had to plot the spectrogram of the signal. I tried to maintain a plot of the spectrogram to 0 for 4S and another 4 s to 8 s. I'm trying hard to draw the graph of the two together, to form a parcel from 0 to 8 seconds, in the spectrogram. In addition, the time axis will continue to increases in 4S interval with a spectrogram updated. I wonder how can I realized by having two spectrogram with two different time interval to display a common conspiracy? Thanks much for the advice.

    RDG

    kengkc

    Hi kengkc,

    Correct me if I'm wrong, but you say that you have the data for the first 4 seconds of your acquisition (t = 0 to 4) and 4 seconds following your acquisition (t = 4 to 8) and you want to combine them into a plot? I guess that since you were able to draw in a graph of intensity to begin with, they are already in the tables.

    If that's what you want to do, you can easily concatenate your arrays using the Array function build (which means to add a table at the end of another person). Add your function Array of build of the subpalette of the table and make sure that you right-click and choose concatenate arrays so that you get more dimensions in your resulting table. Then expand the function Array build so that you can wire your matrices inside.

    Please refer to the attached screenshot to get an idea of what I mean.

    I hope this helps.

    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.

    If you need anything else don't hesitate to comment here .

  • Need help to print a logo on several pages using the ^ graph of order

    Hello.

    I'm using Adobe Output Designer 5.7 (formerly Jet Forms).

    Our logo was incorporated originally in about 100 forms of Jet (*.) Files of the IFD).    There was the ability to print multiple logos of the same *. File of the IFD.

    I found that I could use the ^ graph command.   But the logo only print on the first page.     In the. * IFD file it is 60 pages/subforms.   Page 1 contains the data header and footer of page 1.   Page 2 contains the data header and footer that are used on Pages 2 - N.

    I'm passing to JetForms SAP data.

    I tried several options, but it is impossible that it works correctly.

    The full path and the name of the logo is stored in the variable & T_LOGO_FILENAME &.

    Here's what I tried to do and results information.

    Attempt 1)

    ^ COMPANY_LOGO FIELD

    ↑ GRAPH & T_LOGO_FILENAME &

    This displays the logo on the first page.    It print the logo where the COMPANY_LOGO field appears in JetForms.

    The first page seems perfect.

    The problem is that no logo appears on page 2.

    Attempt 2)

    GLOBAL COMPANY_LOGO ↑

    ↑ GRAPH & T_LOGO_FILENAME &

    Logo print in the middle of Page 1.   It does not print when the COMPANY_LOGO is located in JetForms.

    No logo prints on Page 2.

    Attempt 3)

    ↑ GRAPH

    & T_LOGO_FILENAME &

    This displays the name of the file in the middle of the first page.

    Attempt 4)

    GLOBAL COMPANY_LOGO ↑

    Michelle tests

    The text "Michelle Testing" appear on Page 1 and Page 2 in the correct position on the screen.   It prints where the COMPANY_LOGO field is in the form of Jet.

    We will need to add or change logos periodically.    We are now looking for dynamically pass the name of the file to JetForms, so that we have no need to edit and compile 100 *. Files in IDF every time a new logo is added.

    Any suggestions or recommendations?

    Thank you
    Michelle

    SOLUTION

    I need to set the type to "Graphics" in the form of Jet.  (The type was originally 'Text').

    The code is SAP looks like:

    ^ COMPANY_LOGO FIELD

    & T_LOGO_FILENAME &

    The result is perfect now.  Logo print in the right position on each page.

Maybe you are looking for
