3d PLOT DIRECTION
How can i programically change the 3D graph direction that I want to view.
I know how to view and adjust the projection, but what about the graph's direction meaning XY, XZ, YZ, and user defined...
Thanks!
You can use a standard property node and wire it to the 3Dgraph out terminal. This will give you View latitude, View longitude View distance properties. I wired these into a bundle node and made an indicator inside a for loop. You can play with the properties and view before running to see how these values change.

How to invert plotting direction
Hey everyone,
I am performing the raster scan and plotting the image with 2D Intensity graph. It would be nice to change the plotting origin and direction (to make the image match to physical reality). What do I mean:
Is it possible to make upper right corner the origin, and to make upper left corner the positive X direction and Lower Right corner the positive Y direction?
Thanks in advance,
D.
Solved!

Open Beta: New toolkit for high-quality plots
I'd like to let everyone know that's we're running an open beta for a brand-new LabVIEW toolkit, aimed at making publication-quality plots directly from the block diagram. In addition to regular line, scatter, and bar plots, this toolkit also supports advanced features like 2D contours, vector fields, streamlines, alpha transparency, and inline math using LaTeX. You can save plots directly to disk in half a dozen formats, including PDF and PNG.
We call it the "Advanced Plotting Toolkit", and it's available at http://www.advancedplotting.com along with example VIs and documentation. The beta is free and distributed as a standard .vip package with no dependencies. If you have the time, we'd love to hear your feedback. That doesn't just mean bug reports... this is an amazing community and we'd love feature suggestions as well. Comments are welcome here or by email ([email protected]).
I've included some screenshots of our example VIs below to give you an idea of what the output looks like. Btw, there is also a stand-alone demo app (built using Application Builder) that you can use to test-drive the toolkit without installing anything in LabVIEW.Intaris wrote:
All depends on performance, will report back as soon as I have numbers.
Performance does not seem very high but I also don't think that is the main purpose. You don't use this to update a graph millions of times per second. Instead, it is mostly used to show a finalized result for puplication quality output or for a report.
The toolkit looks well put together, and contains extensive help. The installation does not add examples to the example finder, so I recommend to immediately download the examples from their web site.
Some features need a more detailed explanation, e.g. the definition of "symlog" for the axis mapping.
My understanding (wild guess!) is that this is a LabVIEW interface to an existing open source graphing package (matplotlib?) and as such is pretty polished. Nothing wrong wit this. The generation of publication quality advanced plots is a weak point in LabVIEW and it is a pain to make your own from scratch (example).
Overall, I like it. Still need to play a little more.

How to make a Line Chart curved instead of straight from point-to-point?
I have a Line Chart that is is very jagged and plots directly from point to point, like this:
http://img818.imageshack.us/img818/7408/testhb.jpg
But I want to achieve something that looks a bit smoother where the line instead is curved from point to point, like this:
http://download.oracle.com/docs/cd/E12839_01/bi.1111/b32122/img/curvedline_graph.gif
Is this possible in Xcelsius 2008? I couldn't find anything in the graph's properties and I also had no luck when searching google/these forums for a solution. Thanks for the help!Hello Richard
I have come across the same scenario today and I saw your .swf file and it was exactly what i was looking for.
Can you please be kind enough to send me the .XLF fil on <email address removed>
Thanks

Oscilloscope programme-Device communication
Hi all. I want to implement Java code for an oscilloscope that interacts with a device and changes its state accordingly. Could you help me out? Ta in advance.

JFreeChart however is not optimised for realtime systems like an osciloscope.
Unless your refresh rate is lower than once every few seconds (at most) you're better off writing a customs library for creating your graphs, plotting directly onto a canvas.Didn't know that.
Thanks.it works well enough when the volume of data is small, but when the volume becomes large (and with an osciloscope you'd quickly get to tens of thousands of data points if you have any realistic sampling rate) it slows right down.
It's mainly an issue with the memory structures being employed (quite a bit of copying and iterating going on in there which is less than efficient with high volume data). -
I have an array of channel names for a simple vi I wrote and I want to input them into the plot legend. I typically use ring controls to allow different users to select what they want to see, but beyond 3 or 4 it gets confusing. Is there a way to take an array of strings and input them directly into the legend string slots using a property node? I have spent hours searching to no avail.
Thanks!!
AdamYes, of course there is! Try this:

Using LabVIEW to Generate an XY Graph of Multiple, Indexed Plots?
Hello,
I have written a LabVIEW Program (using 8.2.1) to characterize FETs using GPIB instruments. At it's most basic level, the program sets a voltage across the Gate-Source terminals of the FET, sets a voltage across the Drain-Source terminals of the FET, reads this second voltage, and then reads the Drain-Source current. The Drain-Source voltage is then increased, the current read, and so on. In this manner, the Drain-Source voltage is swept from 0V to some defined maximum (dependent on the FET being tested) and an array of data (I_{DS} vs. V_{DS}) is generated. The Drain-Source is then reset to 0, the Gate-Source voltage is increased, and the entire process is repeated.
My problem is this: I need to generate a single Graph (I think it should be XY, but not entirely certain), that plots all of these IV curves (each curve for each Gate-Source voltage) and indicates the Gate-Source voltage for each curve (in an indexed legend of some sort). Does anyone have any suggestions about how I should do this? My program is entirely based on For Loops and Sequence Structures. If you need a screen shot or want me to upload the program, please let me know. Fair warning, though: I am a LabVIEW novice so while the program functions correctly, it is not the prettiest in the world.
Thanks for any help you can provide.
Michael
P.S. I searched the forums and didn't find this question already posted. If, however, it was and I just missed it, could someone direct me to it? Thanks.Vincent, Jon, and Andrew:
I still need some help. I used the 3524.vi Example for the XY Graph: x-array, y-array definition to generate the kind of multiple plot xy graph that I needed. My problem now is I would like to re-index the plots so that they are labeled according to the Gate-Source voltage I am applying. Each curve has its own, distinct Gate-Source voltage and I would like to label each curve with its Gate-Source voltage. Currently, the plots are labeled in the legend: Plot 0, Plot 1, Plot 2, ... Plot n.
How should I go about doing this (is there even a way to do this)?
Again, any help would be greatly appreciated.
Michael
P.S. I have attached a copy of my program to this message. As I said, it isn't pretty, but it works so far. Hopefully this will help you in forming your suggestions.

I'm running a full updated Arch x86_64 release.
Any suggestions?
Thanks in advance,
RobertoHello BajaBoy,
I think it would be easiest to figure this out if I had the data to look at. If you can send this too me (I will treat this confidientially and it will be deleted after we got it to plot) please sned to me me directly at National Instruments.
My email address is my: first name DOT last name AT ni DOT com (no middle initial!).
We'll get back to you with an answer the same day unless we run into the Thanksgiving holiday before we get this.

How do I change the number of plot areas in a Mixed Signal Graph
How do I *programatically* change the number of plot areas in a Mixed Signal Graph? I recognize that the developer can choose to add or remove a plot area during edit mode but I want to select between 2 or 3 visible plot areas and scale the plot areas appropriately. Is there a property that tells me how many plot areas (or yscales) there are? I also need a property that I can write to as to set the number of plot areas available.
Aside from manually making too many plot areas and then hiding the unneeded plot areas how can I do this?
JonathanHello,
I don't think that is possible - I searched the property and invoke nodes but didn't find something to do that. This would make a great product suggestion though, which you can submit (it goes directly to R&D) by clicking the word feedback in the bottom left corner of the Contact NI page linked below:

I'm trying to plot data from a table in
a ChartControl object. The table consists
of two columns, one contains a numeric
value and the other contains a date value.
I'd like to plot the numeric value on the
Y axis and the dates along the X axis.
I've got the same data displayed in a grid
format, and that's all fine.
This seems like a simple enough thing to
do, but I haven't found a basic page of
documentation to guide me in the right
direction. How do I do this?Use Reshape array to turn your 2-D array into a 1-D array. You will need to wire in a constant of 40 since you will have 40 elements in your new array. Convert the 1-D array to a cluster with Array to Cluster. Right click on that function and set the size of the array to 40. Wire that cluster to the waveform chart. Now each of your 40 values you get after the double For Loops will run will append their new data to the 40 lines on your waveform chart.

Charts: how do I determine when the mouse is in the plot area
I'm trying to implement logic that will do the following:
Panning plot within plot display area by clicking and dragging mouse
If the user clicks and drags in the chart plot area (the region where the chart plot actually displays, not including the axes, legends, titles, etc.), I want to be able to provide the effect of panning the plot (e.g. similar to grabbing and dragging a map in Google maps) within the plot display. This makes the most sense, of course, if the user has zoomed in to some level and the entire plot is no longer fully visible within the display.
Zooming on a plot
If the user places the mouse somewhere in the chart plot area and uses their mouse wheel, I want to be able to provide the effect of zooming in and out of the plot. The plot area itself must remain at its original size, just the representation of the plot needs to simulate the effect of being zoomed in or out on.
Thoughts, suggestions, ...
To make the zoom and pan effect, my thought was to adjust the axes bounds as appropriate to simulate these effects. The trick for some of what I'm planning on doing is finding out where the mouse is in the plot area (not the whole chart) so that I can find the x,y offsets from the plot origin (which appears to be in the upper left - at the chart level anyway). For panning, I don't think I care what the offset is, just that it's within the plot. For zooming, I may need to know where the mouse is in the plot so that the zooming could be centered on that location in the plot. This makes me think that it would also be helpful to find out how to translate the mouse x,y pixel position to a corresponding x,y value in the plot data domain.
I've been experimenting with attaching event handlers to detect various mouse actions and what information can be gleaned from these events. So far I have not found anything that allows me to determine the bounds of the plot region in the overall chart. I can get the mouse x,y position, but I don't know where it is in relation to the plot area bounds. I don't want to initiate a pan of a plot if the user happens to drag their mouse somewhere outside the plot area (i.e. over an axis, legend, etc.). Also, it would not make sense to start a zoom on the chart unless the mouse is over the plot.
Please let me know if this seems to be a reasonable approach, and if not, please suggest any ideas for alternatives. Any help, ideas and suggestions regarding how to solve these issues and/or determine this information would be welcome.I experimented a bit and it seems the plot-content is the Group containing, well, the content of the plot. So in a line chart it's the smallest rectangle containing all the lines and the graphic at the data point (little circles, by default). What you probably need instead is the chart-plot-background.
Here's a quick example of a panning chart. There are probably better ways to manage the mouse dragging (it behaves somewhat badly if you drag out of the plot area and then back in, for example) but it gives you the basic idea. My original idea of adding a mouse directly to the plot area failed as the event doesn't get propagated to the plot region if you click on part of the plot content (a line, for example).

Reducing plots shown in legend causes error
I am using a waveform chart for a classic scope display, channel 0, channel 1 and math. Sometimes however I would like to set up the scope so the math channel is configured on the waveform, but not displayed, and not displayed in the legend either. It's easy enough to set it up to not be visible on the waveform, but making it not visible on the legend, either by reducing the number of plots shown, or by changing the legend height, so that in effect, the number of plots shown is reduced--either method makes later attempts to modify settings for the math channel cause an error (setting the active Y scale = 2 causes an error, since math is the 3rd scale, or 2nd w/ 0-based indexing).
Is there any way to make it not visible in the legend without causing an error for active scale or other properties I would like to set?First, I was confused in my statement on Scales versus Plots. You were correct in your reply, and I went back and looked at my code, which was actually using the Active Plot as you said it should have been, not Active Scale. I do use separate scales for each plot, hence my confusion, but that was not directly related to the problem I was having.
Second, your example was most helpful--thanks for posting that.
Third, after seeing that your example worked as desired, I tried to make it line up with my version of reality It didn't, so I started to look into the differences.
- I am using a dynamic signal waveform graph instead of the kind you used.
- I rewrote your example with a cut and paste of the waveform graph I was using. The property nodes had to then be re-selected properly since the names didn't correspond on a 1 to 1 basis changing over to the dynamic signal graph (for instance Plot.PlotName -> Plot.Name)
- After some hair pulling, I tracked down the errors I was having and was able to reproduce them in simplified form using your example.
As it turns out, the root cause of the errors I was having is not having data displayed. I was trying to set up the graph and plots, colors, names, etc... before writing data. As you can see from the modified example, that doesn't work real well, unless you write an almost null array (1 set of zeroes) to the indicator. A lot of the confusion came from getting errors sometimes when trying to set the Active Plot, and not getting them other times--no reproduceability.
In the attached example, you can see that by setting math visible in the plot legend, you can modify the name and color, but then setting it invisible then visible again erases all the settings for that plot, so long as no data is displayed on the graph for it. With no data, and no visibility in the legend, trying to modify the active plot settings results in errors. I'm not sure whether this is a 'bug' or a memory management feature of dynamic waveforms, but it has definitely caused me quite a few headaches in the last few days. I think the short of it will be to initialize with a set of zeroes and that should take care of things. Thanks again for posting your example.

Plot colors mismatched with legend
Does any happen to know why colors on a graph would not match the colors indicated in the legend?
I am trying to use a property node to set the color and name for each set of data which is displayed. The colors and names are displayed properly in the legend, but the color of the plot itself does not follow.

View_Collected_Data.vi 132 KB
data.txt 6 KBThe loop knows how many times to go due to a feature of LV called auto-indexing. If you pass in an array and let it autoindex on the boarder, the loop will automatically pull out the next value in the array with each iteration--AND set the number of time to loop before stopping. Compared to the hoops C makes you jump through to use arrays, this is indeed Very Cool...
Note that if you wire both the N terminal on a FOR loop, and autoindex an incoming array, the loop will iterate the smaller of the two sizes. For example, if you wire 5 to N and pass in an array with three elements, the loop will only go three times.
Finally, always remember that a FOR loop can iterate zero times. In that case any outputs coming directly from the loop will be
the default value for the datatype. Arrays will be empty, numbers will be zero'd and (this is a biggie) references numbers will be invalid(!).
In the case of your code, I modified the logic such that it generates an array of indexes that has one element for each signal selected. This array drives the loop that sets the plot properties. Note that if the operator selects more than 5 signals the higher-numbered plots will be undefined in terms of color and label because you only specify 5 colors in an array. (Input an array of 10 items and an array of 5 items and the loop only goes 5 times.)
Note that, although it's not used here, auto indexing also works with outputs. In that case though, the loop will automatically collect an array of the output values--one element per iteration.

How do I change the name of several plots of a graph/chart. (programmaticly)
Heey everyone, title says it all.
I already tried using active plot with a forloop, but for some reason that doesnt work for me :s
Checkout the picture in the appendix, that`ll explains my problem.
In the block diagram you`ll see a stringarray :
0 = name 1,
1 = name 2 and
2 = name 3.
For some wack reason the plotnames are set in a different order. Also checkout the program while using debug, then you`ll understand directly what my problem is.
Thank you!
Currently using labview 8.2.1
Solved!

Using XY Graph to plot current and voltage
Hi,
I'm making an I-V curve tracer, and am hoping to plot current and voltage measurements I'm acquiring onto an XY Graph in realtime. I'm using Labview 2010 on Windows Vista, with the VISA drivers installed; my acquisition hardware is an Arduino Uno communicating over USB to serial via VISA drivers.
My data is coming in over the serial port formatted like "voltage,current":
237,521
320,402
I've read through the relevant documentation for the graph builder, the 4 samples included with LabView, and quite a few posts on this forum. I modified Jazlan's sample VI to read the current and voltage, and display the values on the front panel - it works just fine. However, when I wire those values to an Express XY Graph builder (and set the 'clear data on each call' property to false) and run the software, it just sort of freezes... I try to stop it, but it keeps running for about 10-20 seconds. The current/voltage values are not updated, nor is anything displayed in the XY graph.
Am I not sending the correct input to the graph builder?
Should I just wire up my values directly to the XY graph by concatenating values to an array, and then clustering it?
Also, on the right border of my case structure, one of the orange squares is not solid - how do I fix that?
any help much appreciated!

project.vi 76 KBthanks for the tip Tim,
I wired up the stop button to the VISA close block, and now I'm able to run and stop it multiple times without freezing.
1) I know how to add shift registers, but why do I need one? It doesn't seem like I need to pass values from one iteration of the while loop to another...
regards,
