Plotting 4D data (3D scanning grid)

Hello,
I'm looking for a bit of advice on how to best proceed with my LabVIEW application.
My application typically consists of an XYZ positioner that scans an area of 10x10x10 mm and measures every 0.1 mm in each of the 3 axes.
In total I have 100*100*100 points equally distributed in a 3D grid.
For each of these points an intensity value is being acquired by the data acquisition hardware.
I now want to visualize this data. I was thinking of doing it via a 3D graph but could not find a suitable example. Most of the 3D graph examples show a few points scattered in 3D. I have a real 100x100x100 matrix that I want to visualize...
Any idea how to do this with a 3D graph.
You could say that I am looking for a 3D intensity graph.
The only solution I can imagine is that I let the user select a single intensity value and only display that intensity value in the 3D graph.
Does any of you know a good way to display all the intensity values in a 3D matrix inside a 3D graph.
Your expert advice is greatly appreciated!
Kind regards,
Kirsten!

Ok, so here is a quick proof of concept of a 3D Bubble Graph. As a static picture it is just about okay, but if you run the vi you can grab with the mouse and rotate the plot to really see the ball distrubution. This is just 10 *10*10 but it should scale and you can add colours as well, or colours instead of ball size, or whatever.
The vi is a bit messy but demonstrates the concept.

I'm doing a scan around a line by sampling data 360 degrees for every value of z(z is the position on the line). So, that mean I have a double for-loop where I collect the data. The problem comes when I try to plot the data. How should I do?

Jonas,
I think what you want is a 3D plot of a cylinder. I have attached an example using a parametric 3D plot.
You will probably want to duplicate the points for the first theta value to close the cylinder. I'm not sure what properties of the graph can be manipulated to make it easier to see.

My Data acquistion Scan locks up until I move the Mouse

I have set up a data acquisition Scan and am using a while loop to read the data. Every so often the scan will just stop, like its no longer getting points and the program will just sit there. As soon as the mouse is moved, however, it picks right back up again. This effect just started happening when I upgraded the software from Labwindows 5.0 to 6.0. What could be causing this and how can I fix it.

How can you tell that the scan stops? Are you plotting the analog input data to a graph? Does the graph just stop updating?
Why don't you add something like add a timer to your program that is continually incrementing to see if that locks as well.

Adding Data in the grid

One thing I am finding a little awkward; Adding data in the grid. It would be nice to be able to use tab to get to the next cell. At present it just highlights the cell and typing doesn't do anything until the cell is clicked. Equally hitting return I would expect it to give me a new blank row. I would like to be able to add a couple of rows of data without resorting to using the mouse at each turn.
Very good initial impressions though.

Yes we should do this as it's what everyone will expect from Excel.

Capturing data from ALV grid

Dear experts.
Can anyone help me to capture data from ALV grid to pass to a BAPI FM.
My ALV grid has the check box as first column and I want to capture only the rows in the grid with these checkboxes checked. I would prefer to do it without OO.
Regards
Sathar

Loop at the table used for ALV data where <checkbox-field> = 'X'.

How to print the data in the grid?

Hi all,
I'm new to java. So, I need some helps.
I want to print the data in the grid. Data could be more than one page. But I have no idea how to start writing code.
Please let me know if you know.
Thank you.
DT.

Follow this steps.
1- the Grid which you wish to print must locate in a class which implements Printable() interface.
e.g.
import javax.swing.table.*;
import java.awt.print.*;
import javax.infobus.*;
public class myGridControl extends GridControl implements Printable{
// add the following statements in the definition section of your class
int m_maxNumPage =1;
JTable m_table;
TableModel m_tableModel;
ScrollableRowsetAccess myRs;
// add the folowing statemnts in the
//constructor or init method or start method
//(Notice:if you couldn't print, possible
//you didn't put these stetment on the right
//location and one or all of them
//are "null".change the location and make
//sure they are not null when you issue a
//print order)
m_table = new JTable();
m_table = masterGrid.getTable();
m_tableModel = m_table.getModel();
myRs = (ScrollableRowsetAccess)masterGrid.getDataItem();
3- add following methods to your class(myGridControl). just cut and paste.
// Print Methods
public void printData() {

4- execute printData() method to print.
e.g. myGridControl.printData();
let me know if you still cannot print.

How to Add a new Currency in HFM Data form and grid (Rates)

Hi Gurus,
Am very new to this forum.
Can someone explain me how to add a new currency to the existing data for or grid in the Workspace.
Regards,
Vinod

Hi Sandeep,
To add a new currency in Metadata, just add in Currencies dimension, and to add in Data form-just send the script what you are using as of now for rest of the currencies, or follow the same steps as specified above. or just add the script A#CLORATE.w#Periodic.C2#XYZ in rows of your data form (where XYZ- is the new currency).
To add a new location in FDM login to FDM web client- click on Metadata--> locations and select the Controls review location where you want to add the data load location, right click and add the new location.

Facing a Problem while downloading the data from ALV Grid to Excel Sheet

Hi Friends,
Iam facing a problem while downloading the data from ALV Grid to excel sheet. This is working fine in Development server , when comes to Quality and Production servers I have this trouble.
   I have nearly 11 fields in ALV Grid and out of which one is PO number of length 10 , all the ten numbers are visible in the excel sheet if we download it from development server but when we download it from Quality or Production it is showing only 9 numbers.
Can any one help me out in this case.

hi...
if this problems happens dont display the same internal as u finally got.
just create new internal table without calling any standard data elements and domains... but the new internal table s similar like ur final internal table and move all the values to new int table.
for eg.
ur final internal int table for disp,
     data : begin of itab occur 0,
                    matnr like mara-matnr,
               end of itab.
create new like this,
           data : begin of itab occur 0,
                    matnr(12) type N,
               end of itab.

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.

Plot dynamic data with time stamp

Hi All
I would like to create a plot of dynamic data, (Voltage readings taken with an In 6008) versus time.
When the loop starts taking voltage data I would to plot the data versus elapsed time. Voltage versus time elapsed. I have read many examples and tried for many hours to get this to work.
Please help!
Mike

Hi Mike,
Are you using a Waveform Chart? A chart will continuously plot the data versus time as it is acquired. Try right clicking on the x-axis and selecting Properties>> Display Format. Here you can change the way time is displayed on the x-axis. You can also adjust the way the data is displayed by right clicking and going to Properties>>Appearance>>Update Mode.
I hope that helps! If not, can you indicate what specifically you have set up in your code and how the result is different from the plot you would prefer to create.
Thanks,

3.0.02 EA1 - Edit table data in a grid

Editing table data in a grid is broken in 3.0.02 EA1 under Windows XP Pro SP3
Bug #1: When not in editing mode the cursor keys must move the focus from a cell to cell. Instead an edit mode is activated
Bug #2: There is no way to leave cell edit mode using keyboard. Esc must cancel the edit, Return-key must confirm at switch to the next cell. Have to use mouse...

I just tried on my VM and i don't see this behaviour on 3.0.
What i do see is that Bug number 9201495 is still available although i reported this issue on 2.1
Updating the columns in Data Tab - is a bit awkward
