Loose graph axis with cursor in 3d graph

I added a cursor to a 3d contour plot, which gives location and z value. have displayed as xy projection. when I am moving the cursor, I loose the x and y axis, and the contours become dots.
kind of annoying. any properties I can change?

Hello Ennis,
I don't know if there is a property that can accomplish what you want. I have been playing around with the 3D graphs for quite awhile. I'll keep looking and let you know if I find anything out.

Problem with the number format in the graph axis with Report Generation Toolkit.

Hi!
I'm trying to use the Report Generation Toolkit to plot some graphs in Excel.
My first problem is that I don't know how to configure the number format in the Excel Set Graph Font.vi so that my numbers are correctly displayed in the graph's axis. The only given option is general (0,0) but this is not enough for me, my numbers can get really small so I need engineering notation or fraccional format.
Second: I also insert a table with the graph source data, but the numbers are not correctly displayed either: for example:
0,75 is shown as:
0,750000
but 1,25 is shown as:
1!250!000
My guess is I am making to much or wrong string to number conversions or Excel is getting it wrong but I can't find my way...
Can someone help me with this?
Thanks,
Isabel

Here is my VI, it's just a trial so it can look messy...
Thanks,
Isabel

Automatic Cursor Movement in one Graph, in accordance to the cursor in another graph

I am using two XY graphs each with 4 cursors. I want to assign each cursor of graph A to each cursor of graph B such that the corresponding cursors in graph B moves in accordance to the cursors in graph A.
I have used Active cursor, Cursor.PosX and it works for one cursor. However when I use the same concept to change the active cursor value and faciliate the automatic movement for all cursors they do not work.

Hi,
As requested I would like to post the solution as to how I tacked the problem. It was actually small mistake on my part. When I connect the two property nodes for each XY graphs I should connect ActiveCursor to ActiveCursor and Cursor.PosX to Cursor.PosX. What I did was connect the Active cursor of A graph to the cursor.index of B graph. I have attached a small screen shot of connecting the first cursor of A graph to the 1st cursor of B graph so that the cursor in B graph follows the cursor in A graph.
In order to connect more cursors as in my case, the only change to be made is the change in the Acitve cursor constant to, 1,2,......

Rename cursor axis label for a XY Graph

Hello,
I am using Labview 8.2 and would like to relabel the axis of the cursor legend for a XY graph. Presently the cursor lengend contains X (for the X axis) and Y for the (Y axis). I would like to be able to rename the labels of the X and Y axis of the cursor lengend to give the user a more accurate description of the axis labels.
Regards,
Kaspar

Go to Solution.

The changes that were made changed the names of the cursors, not the name of the X and Y axis. Think of it this way suppose that I have a X Y graph of Frequency (on the X axis) and Amplitude (on the Y axis). I create a cursor on the graph and move it around the waveform to examine the characterictics of the signal. When I move the cursor I would like the see the frequency and amplitude where the cursor is at on the signal. Right now the user has to remember (not to difficult) to figure out that the X axis is frequency and the Y axis is amplitude.
So I would like to be able to rename the header of the cursor location from X to Frequency and Y to Amplitude.

Saving "Waveform graph" with cursors, set of different colors, in an image file

Hello:
I'm trying to save to a file, a waveform of a "waveform graph" that has cursors, which have different colors. When opening the file I can see that the waves are plotted defined color, but the grids and cursors are colored black.
Someone can tell me what to do, so that the file is saved with the original colors of the "waveform graph"?
Best Regards

Probably this is happening because you are using the Invoke node Image Export, which captures an image with less information. However, if your application allows, using the Invoke Node Get Image, which captures your control, displays all the colors of your waveform, include cursors and grids colors.
In this link bellow, you can see how use this Invoke Node:

Multiple y-axis(with different scale) on a xy graph

i have an xy graph in which i have three y-axis with 1 x-axis. iam able to name each of the axis as well as set the x-scale min and max each.
finally iam able to see the three plots

maybe this pictures can help to see my problem.
note1 before taking the first picture i changed the range of one plot from right on the graph from -50000-50000 to 0-5000 as a result on pict#3 the black plot looks a bit bigger.
i would like to be able to see both plots the same size. (example the size of plot color black on the pic#1, or the size of plot color purple on the pic#3)
regards

Graph xy move cursor programmability

Hi, i have this problem,
i have graphXY with one cursor, "Snap to point" "Channel 1", when programmability associate one position(x) for the cursor, no accept the new position. Why?
Hola a todos, perdón por mi inglés, pero tengo el siguiente problema, Tengo un gráfico de tipo Xy, en el cual tengo un cursor asociado al Plot 1 bajo la modalidad Snap to point, si programáticamente quiero cambiarle el valor X a ese cursor, no solamente no lo hace, sino que vuelve al princicipio de la señal. Cómo puedo evitar esto?. No quiero que funcione el cursor en forma free, porque no me toma los valores del Plot.
Podrían saber por qué es esto?
Muchas gracias, saludos, MFS.

So what is the question about... I have to use XY graph in my program. It is used in Loop while cycle. It shows the statistic of a variable. I am using cursors in this graph to check the actual value of a variable in different period of time. But there are 7 variables and it is extremely hard for user to check each value independently. So I tried to make them moving on the X axis (TIME) together using the property node (cursors reading the position (only X axis, Y axis status lock to plot) of the major cursor and follow it... Everything looks great? But it did not work when I am trying to move the major cursor manually on graph... It works only when I am using the cursor movement buttons... But they work very slowly when there is a lot of data in graph.
I want to find out is it possible to make seven coursers mouthing together By the X axe and be Locked each at its plot by Y axe manually (Using mouse moving on a graph). Is it possible? If it is than how to do it?

Multi plot cursor in Mixed Graph

If Digital waveform and normal waveform graph is plotted in a mixed graph, and if I choose watch all plots(multi plot) in cursor, LabVIEW closes immediately with an error popup dialog
I have attached the print screen image of that error popup
Attachments:
error.JPG ‏188 KB

Hi Stephen,
           I found a considerable solution to overcome that error.
           Build all the array data at first and then generate digtal
waveform in single instance.
           ie., With number of numerical array data, build a 2D array of
numerical data and make a transpose and then generate a waveform.
           It generates number of digital waveform equal to that of the
column size of 2D Array.
           Do not build generated digital waveforms. This creates an error
while using multi plot cursor--> watch--> All plots.
           I have attached the modified, bug removed Vi with this message for
your reference.

How to add a scroll bar within a view window ?I want to display x and y axis outside the scoll window and keep those axis static and move the graph within scroll area

how to add a scroll bar within a view window ?I want to display x and y axis outside the scoll window and keep those axis static and move the graph within scroll area
ananya

Hey Ananya,
I believe what you want to do is possible, but it will not be
easy. If you want to add a scroll bar that will scroll the graph
back and forth but keep the axis set, you would want to add a
horizontal or vertical scrollbar. Then you would create an event
handler for the scroll event. You would have to manually plot
different data within this scroll event. Unfortunately, there is
not really a built in way to do this with the Measurement Studio plot
control.

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

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. )

Line using cursor in xy graph

hi
how i can draw line using cursor in xy graph
Solved!
Go to Solution.

Hi bijal,
Not sure what you are planning to do. But you could start with:
Creating a XY graph.
Right click on the XY graph >> Visible Items>> Cursor Legend.
Right click on the cursor legend >> Create Cursor >> Free. Up to this step, you should able to create the cursor.
To obtain the data from the cursor, go to your block diagram >> right click on the XY graph terminal at the block diagram >> Create >> Property Node >> Active Cursor. This should create the property node for your XY graph. To change a selected property to write, right click on the active cursor >> Change to Read and it should be like below:
Just input 0 to access the first cursor
Expend it to access an additional properties >> on the second property, click on it >> Cursor >> Cursor Position >> Cursor X.
Expend the properties until you see as below:
It Cursor.PosX and Cursor.PosY isn't changed to write, do change it to write by right clicking on Cursor.PosX >> Change to Write. Do the same for Cursor.PosY
Up to point 6, you should be able to obtain data from the XY graph cursor.
Use those values to plot into the XY graph. I believe you'll need to find a way to plot XY graph by building an array of clusters.
Hope it helps
Warmest regards,

Restrict the movement of cursors on xy graph

hello.
I have an XY graph, with values of 0-10 in X, and of 0-10 in Y. I have two cursors in the graph.
I do not want the cursor is out of the graph area of 10 * 10, I disabled the auto scale, but the cursor can get out of the area of 10 * 10.
I also hope that the value of X of the cursor0 does not exceed the value of X of the cursor1.
I hope you can help me with these restrictions on movement, thank you very much.

Hey there, If you want to restrict the value of the cursors you can use property nodes to do so..
Here is an example; you just need to get the value on X of the active cursor (0 or 1) and then compare those values; if the value is smaller; you can use a case structure and a property node to coerce the values.
Hope this info helps.
Greetings

Placing a cursor in multiplot graph to display all values at the cusor location

We are currently using NI based DAq system which uses LABVIEW 7.1.We would like to know whether it is possible in LABVIEW 7.1 to place a cursor in a graph having multiplot that will disply all the values of parameters at the cursor location?

If I understand the question correctly, yes, LabVIEW can display many parameters of a cursor, including the cursor position (in X and Y coordinates), the array index of the point to which the cursor is locked, the line and point style and thickness, etc. You can also read or set how a cursor locks and whether a cursor is visible or not as well as other properties of cursors. All of this is done using property nodes in LabVIEW and can be done with multiple plots and multiple cursors.

Help with a 2d dynamic graph question

Post Author: eseidel
CA Forum: Other
I have a subreport that I'm having a lot of difficulty with and I dont know if I've hit the limitations of CR or I just don't know how to do it. I need to set the subreport graph parameters on the fly and I can't figure out how to do this. Here is the situation:
My report prints a vendor report card, one vendor per report page. For each vendor, I need to access a table and pull all parts that the vendor supplies our company with. Then, I need to create a seperate 2D bar graph for each part that is listed under the vendor. Since this is a subreport and would run for each vendor, and each vendor can have 1 to n-number of different parts, I need to create these graphs on the fly. Is this possible? Any suggestions. The furthest I have gotten was I can create a OLE DB(ADO) command that retrieves the parts for each vendor.
But from there I am stuck. Once I have these parts per vendor, how can I iterate through them and create a new 2d bar graph for each one? The graph itself would display on the x axis all of our vendors that supply us with a part, ranking them. So if a vendor supplies us with Rubber Hoses, magnesium and Aluminum then I would need three graphs, one for each, Rubber Hoses, Mag, Al that would list the vendor on the x axis and points on the y axis pertaining to that specific part. Understand? Is this possible? Help please. Thank you.
Eric

Faster than an if statement, if you are up to learning it, is the use of the ternary operator.
It's syntax is like this:
condition ? value1 : value2
where condition is a boolean expression, value1 is the expression to be evaluated and returned if and only if condition is true, and value2 is the expression to be evaluated and returned if and only if the condition is false.
Your line of code would be something like:
System.out.print(maze[i][j] == 0 ? "*" : " ");Edit: I am not assuming people are newbies when they are, I realize this.

Problem number 2
Is there a way that i can use XML Desktop and create a line graph with 2 lines rather than 1 plotting
here is my xml for graph i have made with one line
chart:
<Graph>
