Extract y value from graph at any given time

I have a graph with a pre-plotted curve generated from a standard set of results. I need to extract the y value of the curve at any given point. My y value is pressure and my x value is stroke(hydraulic cylinder movement in mm). So for example at 10mm(x value) I need to extract the pressure(y value). Is there a property node I could use for this? any help would be much appreciated.

Hi Alan,
instead of reading values from the graph you may use the interpolation functions from the array palette to do interpolation on the plotted values directly...

Extract high values from graph "PART 2"

This question builds from the post found here.
In th attached VI, how to correctly set the threshold so that all the "spikes" can be displayed in the "Spur List"? I should get 3 points in the Spur List.
Thanks,
hiNi

You're nearly there.
Subtract the Cubic Spline Fit from your actual data. You'll be left with a mostly flat dataset with just your spurs sticking out.
With that flattened dataset, you can perform a simple threshold to extract your peaks.
(i.e. don't worry about taking the threshold of your cubic spline fit. That doesn't tell you anything. Do take the threshold of [Your Data Minus Cubic Spline] to get your spurs. I have no idea why you're deleting your first spur.)
EDIT: Also you can expand out your Index Array to pull both the first and second columns. No need to have 2 Index Array functions.

Using WQL "one-liner" to extract a value from the registry

Can I extract a value from the registry using a "one-liner" WQL command? Something like the following:
Under root\default:StdRegProv
SELECT <Data> FROM "HKLM:SOFTWARE\Toto\Version"
Please note that I am aware of how this is done via script. The problem is that I'm using a management system (SCOM), which only allows me to supply a simple WQL query to perform my evaluation.
Thanks,
Larry

Total of the number of stock lines held in storage at any given time

Hi Experts,
Is there a transaction we could use that will quickly give us a total of the number of stock lines held in storage at any given time? can anyone please advise
Many Thanks

Solved.
SE16 and table LQUA or LAGP. LAGP is more logical but takes longer to generate the result.

Only one Airport Express will work at any given time

Hi,
I use one Airport Express to connect to the internet and another to stream iTunes to my Stereo.
I can only get one to work at any given time!
If I use Airport SetUp Assistant to reconfigure the one that isn't working, it starts and the other stops.
I can only ever see the current one in Airport Admin Utility.
Airport SetUp Assistant shows me two.
What's up?
Best regards,
Ronnie

Extracting all values from multiple menus

Hello all,
Basically I have a jsp that consists of three of what FrontPage calls drop down boxes but I will hereafter call list boxes, each containing a number of options extracted from a database; these values can be moved from one box to another using java script. When I hit a submit button I wish to be able to extract all the values from two of these lists and add them into a database. I know how to extract selected values but I need all the values of both lists regardless of what the user selects and I need the contents of each kept distinct.
Any help provided will be appreciated and I apologize if this question is something all the forum vets have already seen before.
Philip

Only the values that are selected will be submitted
with the form. So, add a call to your form tag's
onSubmit event to call a function like this:<form name='myForm' onsubmit='selectAll()'>
<script language='javascript'>
function selectAll() {
for(i=0; i<myForm.mySelectList.options.length; i++)
myForm.mySelectList.options.selected = true;
// do the same for the other two select lists
</script>
Thanks for the tip, but unfortunately this means that the two list boxes that I want will become intermingled. Is there a way to keep the information in the two lists seperate?
Philip

NullPointerException was thrown while extracting a value from an instance

Dear all,
We have got a null point exception during commit call. According to the stack trace shown below, it seems that it is a problem due to instance variable accessor. As we know toplink use reflection to access the instance variable value. I am curious whether the exception we got is related to any class-loader setting. Thanks a lot.

Dear All,
We have loaded the toplink.jar to container level instead of application level. Don't know whether it is a possible source of error. Moreover, what is the purpose of loading antlr.jar? What is this jar for?
Thanks and regards,

Extract element value from a trigger

Hi,

ExtractValue is a SQL Function not a method
You'll need something along the lines of

How to extract the values from WPBP table

Hi experts,
We are in preparation of a custom report.
In the report we want to have a value from WPBP table.
We want to extract the value of Capacity utilization level from WPBP table.
Could you please let me know the way to extract the value.
Please advice.
Regards,
Sairam.

Hi Sairam,
Why do you try to get capacity utilization level from WBPB. Even if there is split in payroll capacity utilizatian level in WPBP shows the value in IT0008 basic pay.
So instead you can get the required information from table PA0008 Field for capacity utilization level is BSGRD

Extracting unique values from (non-category) columns for chart

Hello:
I've created a worksheet to keep inventory of my Intellivision games. It has the following columns:
Publisher
Class
Network
Title
Quantity
(misc...)
The "Class" represents whether the game is "complete in box" or "loose cartridge." The "Network" represents the general genre or game cateogory. The quantity is how much I have of each.
I have set the first three columns as categories: Publisher, Class, and Network. I also created a bar chart based on the Title and Quantity columns, to show how many I have of each.
The problem I have is that, although it looks real cool and helps me keep the games organized, since a title can appear in more than one "Class" (e.g., I can have one in box, and two loose), the chart includes duplicates, and they are not grouped together.
Is there a way that I can create a graph (or a secondary table) that exctracts only the UNIQUE values from a column that may contain duplicates?
Note that I don't want to put the "Title" column in a category. I want to group by the three major categories and list the games on each.

From the Numbers Help Menu, download the Numbers User Guide. Read the first three or four chapters to get a feel for the app. It's well written and won't take long to read that much.
Then use the Table of Contents and the Search tool to get additional specific directions.
First, delete all unneeded Rows and Columns from your data table. If you have patches of data in a larger table, Cut the patches and Paste them to a blank Sheet area to create separate dedicated tables for your various needs. These small special purpose tables are like Named Ranges in Excel. Name them in the Sheets Pane.
This is how Numbers was intended to be used. The User Guide will describe how to reference cells in one table from expressions in another table. If you use the point and click method of creating references from within the equation editor it won't matter a bit that the tables are separate.
Come back here for specific help on anything you are having trouble with.

Extracting a value from the j_security_check servlet into a JSP page

Hi Folks...
I have a problem as follows:
I log in into the web app, via my login.jsp page. Below is the code for the form that accepts the login information
<form method="POST" action="j_security_check">
<table cellpadding="0" cellspacing="0" border="0">
<tr>
    <td align="right">Username: </td>
    <td><input type="text" name="j_username"></td>
</tr>
<tr>
    <td align="right">Password: </td>
    <td><input type="password" name="j_password"></td>
</tr>
<tr>
    <td></td>
    <td><input type="submit" value="Login"></td>
</tr>
</table>
</form>Login is sucessful and I am brought to the 'studentstub.jsp' page. I would like the user name to appear on the 'studentstub.jsp' page. I used the following code in the 'studentstub.jsp' page :
<td><%= request.getParameter("j_username")%></td> but all I am getting is a null. The 'j_security_check' servlet is not exactly part of my package, but the glassfish app server. Is there anything wrong in the way I am extracting the information from 'j_security_check' ? Hope someone can advise, thanks.

Hi Folks..
I managed to get a reply from another forum and the suggested solution works. I am going to share it with everyone here.
I repalced this line of code:
<td><%= request.getParameter("j_username")%></td>with this:
<td><%= request.getRemoteUser()%></td>The 'getRemoteUser' method from HttpServletRequest returns the name of the authenticated user. I hope this information will be helpful to those caught in a simillar problem. Thanks.

To extract null Values from the source in Infopackage selections - Very Urg

Hi All,
I need to pull the data which has null values from source. I tried to write routine by giving l_t_range-low = '' , space. nothing is working.
Please guide me with sample code.
Very Urgent.
Regards
Mano

Hi Mario.
Assuming that you want to avoid uploading of records having
zero for a keyfigure:
Create a startroutine for transfer rules and add this coding:
DELETE DATAPAK WHERE VALUE = '0'.
OR
LOOP AT DATAPAK.
IF DATAPAK-VALUE = 0..
DELETE DATAPAK.
ENDIF.
ENDLOOP.
'VALUE' represents the fieldname in transferstructure
Please let me know if i misundersttod the issue.
