Plotimages property node of XY-Graph

hi guys,,, Could u guys plz figure out my problem? I use Plotimages property node of XY-graph to make the maker as picture attached. At first, I selected Plotimages.front ,so my
graph is behind of the maker no1. but my point is I want the graph is on the maker therefore, I changed from Plotimages.front to Plotimages.back to get the maker no2 and the
graph is in front of maker but I really don't understand why the maker no1 is still there. Why is it not gone?
Mannie
Thanks a lot

Hey Mannie,
I would suggest to have a look at the Plot Images.vi located at the ...labview\examples\general\graphs directory which shows how to work with this properties.

Limit control to property of a waveform graph

I have a waveform graph in which I would like to limit practically all the property of the contextual menu. Such as:
Visible items, Auto scale X and Y...
There is a way to do that. By setting "Disabled" to 1.
My problem: I would still like to let the user change the Y scale by double clicking it.
Thanks
Nitrof

Nitrol,
Unless I'm mistaken (it happens), the only way to really do this is completely disable all functionality and add the functionality back through your front panel. I would suggest a very easy approach by putting two digital controls (or one array with two elements, or a cluster, or...) which would be the min and max of the Y scale. You can even make it more simple by just adding a Property Node of the graph, selecting the Y scale, and creating a control. That would save you a lot of work. It wouldn't be as neat and tidy, but it would get the job done with the least amount of work.
If you want to know how to do this exactly as you specified, here goes:
Place a picture control over the y scale of the graph. Make the picture invisible (the "T"
color for the frame and the drawing area. Then, with the picture selected, move it to the front. Next, in the diagram, get the mouse down data from the Mouse property in a while loop. Throw the mouse down data into a shift register. Make the loop have a delay (wait) of about 200ms. AND the output of the mouse down button with the previous one. When the output is true (of the AND), stop the loop. You have detected a double click of the Y scale. NOW, you have to add a subVI that pops up (dialog) options for the Y scale. The user will change the scale, and then you can input these into the Y scale of the graphs property node. Yes, its quite complicated, but the results are exactly what you are looking for.
Of course, I always recommend the KISS principle (Keep It Simple Stupid).
Good luck

Xy Graph property node:apply to all plots

I have an xy graph with multiple plots and am using property nodes to give each plot a different color. My problem is that i would like to set the "point style" for every plot to be the same, in other words: create a default point style that differs from the XY graph default.

Don't forget Kudos for Good Answers, and Mark a solution if your problem is solved.

You can do this statically on the "Plots" tab of the graph properties dialog box. You can also get a property node to alter this dynamically by right-clicking on the graph and selecting Create >> Property Node >> Plot >> Point Style.

Y scale flip in waveform graph when using property node.

I'm having problem with property node. I'm trying to build a stackable scope with Waveform Graph And dynamically change the number of plots. It is working. But The Y scale is flipping. The minimum goes on the upper part and the minimum scale goes down. when I change it appearance it's not very fast. It take about 1 or 2 second on my computer.
The way it is build actually is:
Cluster_1 is containing 8 clusters. And each of the 8 clusters are containing a Waveform Graph. By reference I change the property of each Waveform to make visible or not each of the Waveforms.
First I would like to solve the scale problem and second accelerate the redrawing of my scope.
Maybe there is an other way t
o do what I need.
Thanks.

Wow, you have a neat program! The problem with your y axis flipping is because the last four charts in the cluster were programmed with a flipped axis. I relabeled the charts and it worked correctly.
From what I could tell with your code, you do not need the sequence structures. The one inside of the even actually runs the same code twice. Remove this duplication and you should see improvement. Also clusters are slow, so you should not expect it to blink back with additional coding. Use defer panel updates to get that behavior. I incorporated these changes and attached the program.

Multiplot waveform graph plots are different colors when set to be the same with a property node.

The graphs were working yesterday. I made a few changes to another part of the block diagram and now the graphs do not plot all of the plots the same color. I am using a for loop with a property node with the elements active plot connected to the iteration terminal, and plot color to a color box. My for loop increments programmaticaly from another part of the code to create plots as it runs. I have replaced the graphs with new ones and they will work sometimes.
I am using Win2k and LV 7.1
Thanks,

Hi bh3560,
Have you tried chaging the color by right clicking on the line in the plot legend. There is an option to change the color of the plot.

How do I configure the mixed signal graph property node to set the plot names

I have a mixed signal graph displaying digital and analog data in two groups.
I would like to programmatically set the names of individual plots i.e. rather that the digital graph displaying 'Digital 0->Line 0' I would like to set it to 'Signal 1' in the vi.
How do I do this?
Probably via the property node but I cant get this to work without errors? (i.e. i cant find the right combination of node arguments to set.)
Also, I can set the names of the plots of the component waveforms programmatically, but when I bundle the plots together to form the mixed signal graph, the plot names are reset to the mixed signal graph default values. Can this behaviour be turned off?

What are you doing? You need to select the plot first and then set the name, like this:

Linking property nodes to two cursors in one graph

Hello,
I have got one graph with 2 cursors. And I need to by able to set the coordinates of each cursor by using property nodes. However, if I click right button mouse button - create - property node - cursor - cursor position - -then there are only 3 possibilities "All elements", "X", Y" which links only to one of the cursors (actually I don`t know which). How is possible to link 2 cursors`s position property nodes to 2 cursors in one graph?
Thank you a lot for discussion.
Martin Pekar
Solved!
Go to Solution.

Also, if you have more than a few cursors, you can make the code more scalable by using an array of positions and a FOR loop as follows.
Now the code automatically adapts th the number of cursors you actually have.
(Of course all other common sense applies, for example only set this when the position changes. Don't write the same cursor postions with every iteration of the loop over and over. )

Class conflict when programmatically editing graphs with property node

I am trying to programmatically move the cursors on a graph. I want the cursor to look the same on 2 different graphs so I made a subVI. The code works correctly when I have seperate property nodes, but when I try to use the subVI, I get a class conflict -
"You have connected a refnum of one type to a refnum of another type and both types are members of some class hierarchy, but there is neither a simple up cast nor type cast between the two classes."
I am not sure how to fix this. The graph that works is of a waveform, and the graph that doesn't is the output of the FFT Power Spectrum VI. Is the problem that the inputs are different? Or is there some kind of resource conflict when using property nodes in subVIs?

A shot in the dark here. But maybe if you make the subVI's input reference of type GraphChart it would work.

how many plots do you have currently plotted? ActPlot can only be as big as the current number of plots...

How to alter XY graph label according to property node?

I have tried to alter the XY graph label (title) programmatically by making a property node of the XY graph and going to label/text. Then I created a constant to rename the graph, ran the VI but it refused to rename the graph. I have consulted the manual and have searched the forums trying to find an answer. All of the other properties seem alterable, the font of the title, color, etc. but it will not rename the title with the text. Does it have something to do with the owned labels and free labels? If so, is there a way to get around this so I can enter the title through a property node? I am using version 6.1 and would appreciate any help that can be provided. My complements to the forum surfers who ans
wer labview questions, most are extremely useful and have accelerated my labview learning greatly.
Thanks,
CYung

The help for label>>text property, states that it is not available when the VI is running.
If the text string is a free label or a caption, this property is settable when the VI is running and is available in the run-time engine. However, if this text string is an owned label, this property is not settable when the VI is running and is not available in the run-time engine.
Attached is an example how to chnage the title/caption of the graph.

Is there a line style descrepancy with xy graph property nodes?

Hello.
I am attempting to display mutliple bar graphs in a single XY graph control. To color-code and label each one, I set up a for-loop and call each active plot to set the color, plot name, etc. The problematic thing is that when I define the vertical bar graph type by-hand, at the control on the front panel, I have 5 vertical plot style options. The fifth one produces the best results. When I try to set this property node in the block diagram, I have only three vertical plot style options. Is there a way around this?
Appreciate any fedback.
Best,
Mike

Hi Mike,
I read the property node for the bar plots (after having setting it by hand to the one you like) and it appears that the value of that bar plot is 8. I also set it to a different bar plot by and hand then wrote "8" to the property node and that does seem to change it to the last (left to right) vertical bar graph. I am running LV 7.1. If you look at the context help it does seem to indicate that the only values for vertical bar graphs are 1-3 but try writing "8" and see what happens.
Cheers,

I'am having problem with a graph property node by using format & precision

I would like to display an amount of data in a waveform graph and to choose the X scale to display absolute time (whitout date information) or scaled decimal value.
Absolute time is a must because the scaling should reflect the acquisition time and not only a value in hour, minute and second.
Using the property node I can choose between 10 differents formats (0-Decimal, 1-Scientific, 2-Engineering, 3-Binary, 4-Octal, 5-Hexadecimal, 6-Relative Time, 7-Time and Date, 8-SI, and 9-Custom).
Format 7 - Time and Date should be a good choice but LabVIEW set automatically system time AND system date without any possibilities to change anything.
Trying format 9 - Custom ends everytime with error 1077 (invalid property value).
Any help to explain me how to use the format Custom or to give me a solution to switch between time (no date) and decimal scaling is appreciate.
Thank

In addition to the Xscale.Format property node, you also need to set the XScale.FormatString (see a little below the Format entry).
Use %<%.0X>T as format string.

Graph and property node

Hello all;
I want to make my .vi more powerful, so what I wanted to do is next:
1. my input must be: "boolean system check box" in 1D array(this is must have, I need this as input into call library function node)
2. all those checkbox(12) are connected to graph(in this example I choose 12 graphs and one input signal which is same, in real I have different signals, scales...)
What I wanted to do is when I check first check box, first graph will be appears(and on graph will be shown his name, which is same as at check box). And then for example if I choose 3,5,8 check box will be appears 3,5,8 graph which will follow one after the other and so one;
I started to make 1D array check box, but after I group all together and try to rename for example check box 1 to channel 1, it's changing all names not just those which I renamed. I know that I can use "property node" and choose "visible" and "value", but I don't know how to implement together and also moving graphs one after other if I choose for example 1,5,8 channel.
I attach testing file and picture;
thanks

Ok, I figure out, how to implement cluster->array; also add "visible" property; but I still don't know how to create "auto position", if I'd like just show for example 1,3,5 graph(all 3 must be inside TAB, also there can't be any free space from graph 2,4 in this case...). Please look my files (v.8.5, i can save to any other version up to 2011);
