Labview graph

Hello guys,
Someone can explain the better way do plot a graph like the bottom one? The ploblem is the vertical "lines". Can Someone give me an idea?
Thanks

"Better" implies a comparison. Better than what? How are you doing it currently?
Does the image show what you want or what you currently get? What is the problem with the vertical lines, they look fine.
Please explain!

Labview Graph Palette Taking Outputs

Hi,
is there any way to take the output of Labview Graph Palette i.e. when I zoom in can i access the minimum and maximum values of the zoomed in scales.
What I am trying to do is scanning a square and displaying data on an intensity graph. SoI wanted to add a feature which enables me to zoom in on the graph then take the values of the new scales and scan the zoomed in area again in the instrument.
So, is this possible?
Thanks,
Yatin

In LV8.5 (not sure about 8.2) you get "scale change" events, so with an
event structure you get new ranges every time they change.
In <LV8.5 the only option is to poll the range properties of the graph.

Display LabVIEW graphs in realtime from previously acquired data

I have some raw LabVIEW data stored in a BIN file. This file contains about 4 channels of labview graph data that was acquired. How can I open the raw LabVIEW data and view the four steams in realtime? I need to be able to view the data as it scrolls across in the same way as when the data was acquired. Is there a program or premade VI to do this?
I will then use screen capture software to create videos of the labview graphs. If there is a way to directly convert the visual labview graph data into a video that displays the graph in the same way it was collected that would be ideal. For now I would be happy just getting the data displayed in the same way as it was collected.

I'm sure this has been asked before, but I am having a hard time finding the other messages.
Basically you need to create a VI that reads in the binary data from the file. You also need to know the acquistion rate for that data, what is the dt between data points. Now feed that data into a for loop (auto-indexed) that feeds the data one point at a time to a waveform chart. The loop would have a wait statement equivalent to your dT of the data. Thus the loop runs at the same rate as you had acquired the data adding a point at a time to the waveform chart.

Can I add a LabVIEW graph in my C# or C++ application?

I am using LabVIEW Full Development System 8.2 and I have the application builder. I would like to include a regular LabVIEW graph in my C# or C++ application. Is this possible somehow? I know LabVIEW can generate a dll from a VI, but can LabVIEW create, for example, an ActiveX or a .NET component from a VI?

No, you should have Measurement Studio to do that.

How to make my waveform from excel file perodic in labview graph

Hi guys,
Previously I've made a vi which integrates the excel file, to plot the graph values in labview using the values in the excel file to give the me a better flexibility to decide what waveform i want it to be. Can i know how to actually make the graph periodic, as in the waveform repeats, because currently it can just plot out the waveform accordingly to the values i inserted in the excel. I've attached my vi and aso my csv file together. Thanks guy.

So do you want to read the same values over again?
If that is what you wish to achieve then use waveform chart as opposed to waveform graph. I editted your code slightly so that you can see the different.
I hope this helps!

Creating trendline in labview graph

Hi,
does anyone know whether is it possible to create a trendline in labview's graph?
kinda like in excel u can create a trendline but i want to do it in labview, is it possible?

You can use the curve fitting functions to find a curve to fit the graph and then add it as a plot to the graph. Examples ship with LabVIEW on using the fit functions and on creating multiple plots for graphs.

How can I include a Labview graph in a TestStand report?

Hi All,
I have a new need that I have never done before in TestStand. I have a Labview VI in which I am sending results to a graph.. I would like to include that graph in the TestStand report. I have searched the help and the forums and have come up empty. Any ideas out there as to how to accomplish this? Thanks in advance for any help.

Raj - Thanks for the response and that solution does work. The problem is that the graphs that I am including are more elaborate than what TestStand is doing by default. Some of the graphs will have three traces on them to show spectral masks test with lower and upper limits. These graphs will also be used in reports and I would like them to show up larger, kind of like when you have a graph in Labview and you can use its reference to save it to an HTML report.

Labview Graph Problem

Hello,
I have a problem with a tool witch takes excel columns and plots graphs.
The problem is that when i create the png of the graph it additionaly appears the poit (0;0) witch should be on graph.
In the preview i can't see this point. I attached an example.

Have you tried putting a probe onto the data going into the graph to check there aren't any extra data points (i.e. at 0,0)?

Labview Graph Issues

I have fixed this issue in the past, but not with a filter on. When I run my VI the graph polts my data from right to left. How do I change it to plot from left to right? I have tried switching the array inputs to no avail. Any suggestions? I am fairly certain it is an easy fix, but with my limited LabVIEW knowledge I have run out of ideas for fixes. Any help would be much appreciated. Thanks!

Labview graph from excel data

Hello,
I need some help. I have data in excel The first column is a timestamp and the other columns are the data needed.and I am trying to get a graph with multiple plots with these data.
attached here are the excel file and a labview file. In the labview file, the top part is an example I got from the forum, an interesting graph I am trying to follow.
The bottow part is my tentative to extract the data from excel into array and try to use it. but I am stuck here. Any help please!
Thank you,

Plot discontinuous data in labview graph/chart

Hi,
I would like to plot discontinuous data in a graph in labview.
The data is aquired and plotted over time - butduring certain periods there is no data aquired.
I don't want during these times any "line" between the adjescent points - I just want simply "no line".
Maybe the best way to show it is this example of a javascript chart
http://www.highcharts.com/stock/demo/data-grouping
- zoom into the time around november 2005
During certain times there is no data - this is implemented in the datastream as "null" instead of a vaild floating point number - similar to NaN for floating point numbers - the javascript code knows that in this case there should be no interpolation.
Is there any way to have a similar behaviour with labview charts or graphs ?

Yes. Place an NaN value in the array where you data break is before sending it to the graph.

Strange Fonts in labview graph's plot legend.

Hello All,
I am running labview 7.1 on a Windows XP machine and
the default and only language is English (US). Verified this under
Control Panel > Regional Settings.
When I run a VI, I get strange fonts in the plot
legend. They keep updating as the VI runs. Here is a screen shot of the
plot legend:
I change the font to something I can read, save the VI and run it again
and it automatically changes to this unreadable font again. Any ideas
on what I can do? Thanks.

Is it just the font that is off, or are these actually non-printable characters?
Are you graphing e.g. dynamic data types? Do you possibly have weird names for your signals?

Printing a Labview graph in LandScape mode ?

Hello everyone. I have LabView printing an XY graph but it always
wants to print in Portrait mode. I set the defaults of the printer to
LandScape mode and still go a Portrait printout. Is there anyway
to force LabView to print in LandScape mode? This will help the graph
be more readable.
Thanks for any help you can give.
Regards,
Steve Drake

Hi, well after some playing around and touching things that I though
shouldn't make a difference I got it to print in Landscape mode. On
the VI's front panel menu File-Print I switched that to LandScape mode
and what do you know it printed the graph out in LandScape mode.
Now I want to manipulate the fonts on the graph. I have messed with
the cursors and I can put x axis lines
on the chart with a time value
but the text I'm putting up is small so I need a bigger font and I
need to get the text out of the graph itself.
Is there anyway to print the cursor titles vertical instead of
horizontal to the x axis. Thought I would ask anyway.
Thanks to anyone who already knew how to do this.

Labview graph scale labels do not update

I am using XScale.NameLbl.Text and YScale.NameLbl.Text graph properties to programmatically change the labels on the X & Y axis. It seems to work when I run the subVI containing the graph, but when the subVI is placed in an application, they do not update based on the plot data that is selected to be plotted.

WC3000_Histogram_Plots.vi ‏96 KB

I think I understand your question. Your subvi has the waveform wired as an output. In the main vi that calls the subvi, you wire the output to a graph - correct? So you're looking for the graph properties in the subvi to be transfered to the main vi graph - correct?
If this is correct - it doesn't work that way. The waveform is just a cluster of t0, deltat, and the y array of data. None of the graphs properties are passed out of the subvi.
There are many ways to do what you're trying to do. You could wire the returned strings that you use for x and y labels as outputs of the subvi, then update the property node of the main vi graph. You could also pass a reference to the main vi graph to the subvi and make the x and y label changes to the main vi graph in
the subvi. I think the first option is probably easier.

Plotting graph in LabVIEW from MySQL data table

Is there any possibility to plot the data from MySQL data table in LabVIEW graph/chart??
can somebody help me??
thanks...

I am new with LabVIEW and I am also with the same problem.
No problems to write data into MySQL, but when trying to read data neither "fetch element data" or "get properties" answer !
It is not possible to get a simple recordcount using the "get properties". The same script give the right answers with MS Access, only changing the DB reference from "connection string" to a "UDL". Does somebody can post an example retriving data (that runs ok even with a WHERE clause in the recordset) using MySQL ?
The connection string I am using is:
Driver={MySQL ODBC 5.1 Driver};Server=127.0.0.1;Database=DBname;User=root;Password=xxx;Option=785;
