How can I change the X-axis increment in a waveformgraph

The X-axis always increments by 1, but I am acquiring one point of data every 100 ms. So my chart moves 10 times fater that the real time. How can I set my x-axis to increment 0.1 every time I add data to my Waveformgraph in VB net?
The X-axis collection is not showing any property to change that.
I have a continuous data acquisition giving me timed data at 100 ms rate.

Thank you for posting to the NI forums. You can set the update increment of the WaveformGraph plot function by using the overloaded function as follows:
PlotYAppendMultiple( ByVal yData As Double(,),
ByVal orientation As DataOrientation,
ByVal increment As Double )
I did this in the VB.NET example program, "ContAcqVoltageSamples_IntClk", by adding the following line to the dataToDataTable function.
WaveformGraph1.PlotYAppendMultiple(sourceArray, NationalInstruments.UI.DataOrientation.DataInRows, 0.1)
The increment will be set to 1 / (sampling frequency), so in your case, it will be set to 0.1. This function is documented in the NI-DAQmx .NET Framework 2.0 Help.
I hope this helps. Post back if you have any further questions.

How can I change the Y axis to show my values in a descending order in Numbers. eg zero at the top and the maximum value at bottom?

Hi,
I'm just about getting to grips with Numbers, but I'm stumped at the moment with this problem.
I want to show zero at the top on the (y) axis, as zero is the goal and 100 is the starting point?
can it be done? i would really appreicate some help on this.
Kind regards
Rob

Is it so difficult to read given answers ?
Barry described the correct scheme.
In the table "to_chart", the cell A1 contains :
=ROUNDUP(ABS(MIN(Tableau 1 :: B:E))/10,0)*10
The cell B2 embed the formula :
=$A$1+Tableau 1 :: B2
Apply fill down and fill to the right.
On the left edge, the colored rectangle is a text block in which I inserted the label values.
Of course if you dislike this scheme, you are perfectly free to use an other application.

How can I change the Y-axis (circular) grid spacing, in Polar Plot VI?

When using Polar Plot VI, I need more control over the plotting parameters. This means tweaking the sub-VIs in various ways. What I need to do most is make the polar magnitude axis less busy, i.e. only draw circles every 10 instead of every 5 divisions, when using a range of 0 (outermost) to -80 (innermost).
The magic 'magnitude axis subdivisions' variable seems to be generated in Calc Scale Specs sub-VI, and output as an array of clusters, but I can't quite see how it's created and from what.
Please can anyone help me gain control over the number of magnitude division circles generated?
Many thanks!

I think if you go inside the Calc Increment.vi and modify the Increment output terminal it might change what you want to see. Try putting a multiply by 5 or ten into the case structure for when the log is false.

How can I format the y-axis to display durations?

How can I cause the y-axis of this chart to reflect the values in Row 6 [Average Pace (Minutes per Mile)] of the corresponding table in duration format rather than number format. In other words, I need the y-axis to be a list of durations appearing like the figures in Row 6. Also, I need it to begin with the longest duration (10:00) and to climb to the shortest duration (5:00) at the top. I'll should mention that I already tried using the Inspector, but the "Duration" formatting option for the y-axis was not selectable while other formats were. I also tried formatting the y-axis this way to "Same as source data," and this didn't cause it to display durations either, though I had expected it to. Thanks in advance!
Ryan

Hi Ryan,
Numbers can display only numeric values on the Y axis, and those values are always arranged from highest to lowest, with highest at the top.
That said, here's what is possible:
There is, of course, some manipulation of the data involved in this, as well as replacement of the value axis labels with custom labels in a text box.
Here's what's happenng with the man behind the curtain:
While the chart shows the data from row 6, it is actually graphing the data from row 7 (or whatever row you choose to place this data in.
Row 7 uses a formula ( =-60*24*STRIPDURATION(B6) ) to first strip the Duration from the data in row 6, returning a number representing the fraction of a 24 hour day equivalent to the duration in row 6.
It multiplies that number by 24*60 to convert it to the number of minutes (and fractions of minutes) in the duration, and changes the sign of the number to - (negative) so that the shorter values will be higher in the chart.
Selecting row 7 and choosing Line Chart from the Charts Button's menu produces, with one difference, the chart shown after setting the min and max values on the Y axis to -10 and -5 respectively, and incrementing the number of steps on the Y axis from 4 to 5).
The difference, of course, is that the Y axis value labels all show negatic=ve numbers, with no m to indicate they show 'minutes.' To correct this, insert a text box and enter the six numbers 5 to 10, with each followed by an m and a return.
Select the Text box, change the alignment to Right aligned (with the alignment button in the format bar), then drag the box in front of the Value axis labels with the 5s aligned.
In the Inspector, choose Text inspector, then Text. Use the Space after Paragraph stepper to increase the setting until the 10 in the box aligns with the 10 in the Value Axis labels box. You may have to tweak the height of the chart slightly to achieve this alignment.
Select the chart, then choose the Chart Inspector, then Axis. Use Choose Axis Options (for the Value Axis) to uncheck Show Value Labels.
Regards,
Barry

How can I change the display of Inbox in my iPad's mail app- so that it takes up the full screen?

How can I change the display of Inbox in my iPad's mail app- so that it takes up the whole screen, as opposed to just about one third; the other two thirds display the full text of the selected email?

You can't change the display in the Mail app, if you are holding the iPad in landscape orientation then the left-hand third will be for navigation, and the right-hand two-thirds will be an email. If you hold the iPad in portrait orientation then the navigation section becomes a drop-down section.

HT201361 Is it possible to save the screenshot files to a different folder than desktop. How can I change the folder?

Is it possible to save the screenshot files to a different folder than desktop (that is the default). How can I change the destination folder? Thank you, Sal

To change the screenshot capture location to a new place on your Mac, first think of a location that would serve you properly. We like to place ours in a "Screenshot" folder located inside of the User's "Pictures" folder. To change the location to this new location, open the Terminal and enter the following command:
defaults write com.apple.screencapture location /Users/[u]/Pictures/Screenshots/
Replace "[u]" with the name of the user on your system. Once you have entered this command, let's restart the screen capture utility by restarting the SystemUIServer by entering the following command:
killall SystemUIServer
You can optionally log out and back in instead of entering this second command, thus restarting the SystemUIServer. Once restarted, all screen captures taken from here on out will end up in your /Pictures/Screenshots/ folder in the User's home folder on your Mac.

When my husband and I first bought our iPhones, I was the only one with an Apple ID (since he never used iTunes). He used my apple id to get apps. Now he has his own ID, but my apple ID email address keeps popping up on his phone when he tries to download an app. We do not want to have all of the same apps on our phones. How can we change the ID on his phone? I already tried going to Settings>iTunes &App Store> and changing the Apple ID to his account email and that did not solve the problem. To make things worse, I recently changed my Apple ID email address (without getting a new ID) and I do not remember my old password (and this is the address that is popping up on his phone). He does not have any music on his phone and all of the Apps that he has are free. Any help you could offer would be great (-:

All apps are forever tied to the Apple ID that bought them. To stop your id from popping up, you need to delete the apps on his phone, and then repurchase them under his account.

You can associate files from the Bridge level and the Desktop level.

If you want to open files from the Windows Desktop in CS4, these are the instructions:

If you did not get an OS X install-restore DVD with the computer you may need
to buy one from somewhere, and you may be lucky to get a retail OS X 10.5.x
version. The original grey-label install set of software and OS X it shipped with
likely would be an older system than Leopard 10.5. Last versions of G4 Mac, &
G5, shipped with a Tiger 10.4 system; so did early Intel-based Mac. Grey discs
which accompanied other computer build models generally do not interchange.
The last OS X version a PowerPC architecture can use, if supported, is 10.5.8.
A PPC processor at 867MHz & faster should be able to run OS X 10.5 Leopard.
{With the correct disc installer, you can use it to change a password and other
things including re-install, and perform disk utility functions, etc.}
There is a chance you may be able to get a white-label Replacement 10.4 DVD
or Replacement 10.5 DVD from AppleCare or the online Apple Store (800myapple)
from a Mac OS X system specialist; these have been available yet hard to get
as not all persons involved with them seem to know if they still exist until someone
is asking. These aren't retail stock, are special discs for computers who could use
a system later than original old discs; these are complete install discs not for one
specific series of Mac. Generally they'd work in supported PowerPC G4/G5; but
do not replace specialized original install DVD, such as an early Intel mac requires.
You'd need to have a serial number of the computer, and a method of payment
when seeking some replacement system media from Applecare or Apple sales
and these discs are not available in a retail store. The original Retail discs are
labeled differently and shipped in a retail box with a big X on the front. Other
sources for retail 10.4 Tiger or 10.5 Leopard may be online via amazon sellers
or computer resellers who handle repaired Macs. Avoid mystery grey label ones
that were intended to be sold and kept with their original computer kits.
Good luck!

How can I change the settings so when I delete an email from my iPhone it will also delete from my iPad.....very sick of deleting the same emails two times

How can I change the settings wit mail so that when I delete my Verizon email from my iPhone it will also delete from my iPad too.... Seems like I shouldn't have to delete my email in three places...iPhone ..iPad ...and desktop

Don't know which email host you are using, but if this is a POP account, you can't do it. If IMAP, then deleting one email should delete it on all other devices.

How can I change the pitch of a track?

In Garageband 10.03, how can I change the pitch of a track?
It seems that I somehow mistakenly changed the pitch of a guitar track I had recorded, so that al the notes in the track sound like they're about an octave too high.
I don't know how I did that, and how to make the pitch slider appear so that I can try to lower the pitch.
I saw three Youtube videos that show how to change a track's pitch by using the pitch slider, but none of them explain how to make the pitch slider appear.
The pitch slider is supposed to appear in the lower, left corner of my window, but it doesn't appear in my window. Instead the lower, left corner of my window says things like, Region, Notes, Time Quantize, Strength and Transpose.

There's much to learn in Garageband!
If you want a comprehensive introduction to the new GarageBand, have a look at Edgar Rothermich's book:
Edgar's "GarageBand 10.0 How it Works" explains it very well with many screenshots. You can buy it as iBook from the Book store, as PDF, or as printed book from Amazon, Only, this version of the manual has been written for GarageBand 10.0.1, Some features have changed slightly since then.
