Hi ander99,
In LabVIEW 7.1, the instructions to export image are here:
Saving Graphs, Charts, Tables, and Digital Data Controls as Images—Right-click a graph, chart, table, or digital data control or indicator and
select Data Operations»Export Simplified Image from the shortcut menu to save an image of the control or indicator to the clipboard or as a .emf or .bmp file.
I found this from the LabVIEW 7.1 new features page here: http://zone.ni.com/reference/en-XX/help/lv/71/lvhelp/whatsnew/
If you want your program to do the exporting automatically, you will need to use the invoke node rather than the right click option. Attached is an example of how you can use the invoke node to export your image.

Is it possible to make a graph with drag and drop plots and use it as a control?

I am trying to make a graph with multippel plots to use as a control, the plots should be drag and drop. Is this possible in LV 7.0 or do i have to use c++ or WB?

I second Doc-Doc comment. I am not sure what you are asking.
The attached is an example I found on the NI web-site some time ago. I cannot find the link again so here is a ZIP of what I found in a temp folder on my machine.

Scatter plot graphs, more than 2 series possible?

It's been very difficult for me to put 3 or 4 series of data in scatter graphs and connect the dots with lines as in Excel, it just doesn't allow me. I made a graph before using line graph model but it turns out that in the x axis (which in this case is time in weeks) I need to show the distance proportionally (i.e. 0,2,6,12 and 16 weeks) and I can't find how to do it with a simple line graph. Tried in excel and is easy using the scatter plot graph (very simple, using exactly the same data arrangement). But numbers does not accept the series of data (it only accepts X,Y per series) and in second place there is not lines connecting the dots. Any of you guys have a suggestion?. I'd really prefer to use numbers bit do not why is so difficult to scatter graph the data. Thanks

The default for X-Y pairs can actually be pretty handy, though often it is not. You can easily turn it into one X and a bunch of Y's. Connecting lines are also available.
My assumption from your post is you have a column of X values and several columns of Y values.
1) All data for a scatter plot must be in "normal" data cells, none in header cells.
2) Select all the X & Y data and create a scatter chart.
3) There is a "gear" at the top left of the colored box in the table that indicates the data in the chart. Click it and choose to share X values. Now you should have one column labeled "X" and several labeled "Y" and your chart will show each Y as a separate series.
4) With the chart selected (the whole chart, not one of the series), go to the Chart tab of the inspector, go to the series tab, look for the words "connect points" and choose what kind of line you want to connect the points. Alternatively or additionally, you could make trendline curves by clicking on "advanced". Also, you can do them one at a time and choose different settings for each series by selecting each series separately.
If you have gaps in your Y data, it will not connect the points on either side of the gap, you will have a missing line segment.
If your X data is unsorted, some connecting lines may go right-to-left, not left-to-right.

Read data from XML file and plot graph on Ms Words

Hi,
I'm using Visual Studio 2010, what I want to do is written in the title.
so far i was able read and plot graph on a Form but i unable to use the same method on Crystal Reporting.
The method plotting in Crystal Reporting is complicated and it require a fix data set or database which is not suitable for my case because every time the number of column and row or data will be different. (this is what i think base on what i found)
is there a way for me to display the output on a ms words?
and what is the method.
thanks.

Hi Huangcongmazhananzi,
Based on your description, I’m afraid that it is not the correct forum for this issue, since this forum is to discuss the VS IDE.
I might not have the correct detailed answer you need, but I might lead you into the right direction to solve your problem.
If this issue is related to the Windows Forum app, this forum would be better:

Hello,
I've done somthing like that in one application and the example it's on the attached pic.

1 - create graph reference (right click and choose create reference)
2 - pick a method called "get image"

How can I call the jFreeChart to plot graph and get the result in Servlet?

I want to use jFreeChart to plot time series graph, and then output the result in Servlet. How can I call the jFreeChart to plot graph and get back the result? Any source code for example? Thanks a lot!!

Dave,
ServletDemo1 and others were not in the distribution that I got (jfreechart-0.9.4). I found them under the premium demos somewhere in com/refinery/chart/demo/premium, but could not compile. They're complaining, among other things, about missing classes/packages com.refinery.date.SerialDate and com.refinery.ui. Am I using a wrong version of jfreechart?
Thanks,
-Alla
There is a very simple servlet demo in the JFreeChart
distribution:
src/com/jrefinery/chart/demo/ServletDemo1.java
This simply sends back an image to the browser.
A second demo, which embeds the chart in an HTML page
is:
src/com/jrefinery/chart/demo/ServletDemo2.java
src/com/jrefinery/chart/demo/ServletDemo2ChartGenerator
java
...includes a time series chart as one of three
options.

Any ideas, sugestions or examples?
Thank you in advance

Speaking only for myself, I am not sure about the nature of your request.
Could you please post some code showing an example of what you can do now and a jpg of what you desire.

Help using arrays in java

HI all,
I am working on a program that will print out my initials 'A' and 'T' using arrays. I am asked to initialize the first intial to '*' and the second intial to '@'. I wrote the code but the output is wrong. Can someone help me by letting me know what I am doing wrong in my arrray?I just get back my array of 30X30. I also wrote a driver but when I run the program, I really appreciate it so much.
public class Initial
     private char whichinitial ;
     private int MAX =30;//Maximum amount for 2-d Matrix
     char[][] letterMatrix = new char[MAX][MAX];//2-d Array 30 x30
     private boolean first = true;
     public Initial()
     { //FIlls Array full of '*'s
          whichinitial = '*';
          for(int i=0;i< MAX;i++)
               for(int j=0;i< MAX;i++)
                    letterMatrix[i][j] = whichinitial;
     public void setLetter(char letter)
     {//Setter for Letter
           whichinitial = letter;
     public char getLetter()
     {//Getter for Letter
          return whichinitial;
     public void firstLetter()
     { //Creates an A shape
          for(int i=0;i< MAX;i++)
            for(int j=0;j< MAX;j++)
                  if((i>0)|| ((i<6) || ((j>0) && (j<29))))
                     letterMatrix[j] =whichinitial;
     public void secondLetter()
     {//Creates an T shape
          first = false;
               for(int i=0;i <MAX;i++)
               for(int j=0;j <MAX;j++)
                    if((i>1) ||(j < 29)||(j>5)||(i>10))
                         letterMatrix[i][j] = whichinitial;
     public void display()
     {//Displays the Initials
          if(first)
               System.out.println("\n \n \n My First Initial," + whichinitial + ", follows:");
          else
               System.out.println("\n \n \n My Last Initial," + whichinitial + ", follows:");
               for(int i=0;i <MAX;i++)
                    System.out.println();
                    for(int j=0;j <MAX;j++)
                         if(letterMatrix[i][j] == '*')
                              System.out.print(" ");
                         else
                              System.out.print(letterMatrix[i][j]);

I am trying to write a program using a matrix. The size of the maxtrix should be 30X30. The first initial shoulld be initialized to '*' and the secind initial should be initialized to '@'. Both initials should be 30 characters high and 30 characters wide and the initials should also represent the uppercase letter of your initials. I know that the first initial's matrix needs to be filled up vertically and the second initial needs to be filled horizontally but the output is wrong....PLease Help!

Using arrays in a jsf page

Hi guys,
I'm developing an ADF application in JDev 11.1.1.6.0. I have problem about using arrays in jsp page. I have an iterator that brings me data from UCM. I just want to take every documents seperately and use in a Jquery division by division.
Can i have chance to use an array tag in that page? Or how can i make it possible my work in a different way?
Thank you so much,
Erdo

Hi Frank,
I've already use an iterator. I just want to take datas and after close the af:iterator tag. Then i will use those datas in a different block.
My code :
<af:iterator var="node" value="#{nodes}" id="i1">
<af:outputText value="#{node.propertyMap['CSGMNEWS_REGDEF:Desc'].asTextHtml}"
id="ot1"/>
</af:iterator>
I want to take all informations from node.PropertyMap[] and then i will set the values of outputText with those informations. I hope I'm clear.
Regards,
Erdo

Using arrays in apex

hi i want to know if some can guide me how to use array in apex.
i have a tabuler report with 4 columns.
i need to write a validation in the tabuler report for that i need to used array.
can I directly access the colums as i have shown below? or do i need to decleare this arrays some were in apex?
e.g
FOR i IN 1 .. ow_app.g_f01.COUNT
loop.........................
LOGIC
end loop;
from what i understand i can access each column as ow_app.g_f01,ow_app.g_f02,ow_app.g_f03,ow_app.g_f04 does this make sense?
thanks a lot.

Using Arrays in a program

First, I would like to thank everyone in this forum for all the help they have given me over the past few weeks. With that said, I am currently trying to alter the following code to accept and use arrays to end to produce three seperate results. The program now as three hard coded variables which are
Amount = 200000.00;
Term = 30;
InterestRate = .0575;
I need to have the program work the same, but produce results for three different Terms and Three different periods. Below is the code the I am working on, I have added two arrays containing the required information. I am having a hard time coming up with a for statment to move the program through the two arrays. Any pushes in the right direction would be great. I left the hard code variable in place, I know that I do need to remove them and alter the equations. I just thought it would be easier for everyone to understand if I left the code in working form.
