Update plot name in the cursor legend

Hi,
I have a XY graph with its cursor legend set as visible. The plot name changes based on the string that I sent to its property node, but I don't know how to update its cursor plot name? Cursor is snapped to the plot, but the cursor plot name did not update. Could anyone please help me?
Thank you

Here's a hint: I found that if I toggle the Cursor.Cursor Mode from 0 to 1, then the cursor name changes.

Position Cursor on GRAPH either by dragging it OR entering the dsired position in the Cursor legend

I've written a VI that allows the user to import a dataset, view it on a graph, and then use cursors to "filter" the range of data that I'm interested in, by sending the cursor.index values from the first graph to an array subset function which feeds a second graph. The problem is that I'd like to provide the user the ability to position the cursors on the first graph both visually - by dragging - (for "course" control) AND by entering the desired values directly into the cursor legend (for fine control). The problem is that I cannot find a way to do this, since I have to have the Lock Ring set to “Lock to Plot” in order to capture the index information. According to the documentation, the only way to be able to position the cursors via the Cursor legend is to set the Lock Ring to “Free”, which means the index values are rendered useless, since the cursor is no longer locked to the plot. If I leave the Lock Ring in "Lock to Plot", and enter a value in the cursor legend, it does move the cursor, but not to where it should. If I enter a value an x value of 9.0 for cursor 1, the cursor goes to 10.2638. The next time I enter 9.0, it goes to 9.82794. I don't understand what the issue is. Is there a way around this?

Yes Rudi: What I want is for the operator to place the cursors by dragging them (just eye-balling it). The, if they see that the Y cursor (horizontal) is at 10.234, and they want to make it 10, they could simply enter that value in the cursor legend, and the cursor would be placed exactly at 10. The only way to do this seems to be to select the “Free” option for the cursor. However, in order to use the first graph to set the boundaries of the second graph, I have to use the Cursor Index from the first as an input to the Array Subset that feeds the second graph. In order to use the Cursor Index, the first graph has to have its cursor Lock Rings set to “Lock to Plot”. Am I making this any more understandable, or just rambling?

How do I programmatically determine the cursor legend refnum?

I am determining the controls and such of a front panel programmatically as I have a need to be able to modify panels quickly without the manual editing necessary. I need to know how to determine the refnum of a cursor legend for a waveform or XY graph in a programmatic fashion rather than by creating a reference node.

That is a good question. The cursor legend reference is not returned if you get a list of all the object references. The graph is, so you can get its reference and get the cursor legend reference from it. You probably only need to look at the ones with a visible property set to true.

Event for a change in the cursor legend

Hi!
I need to recognize a change of the cursor properties by the user through the XY-Graph Cursor Legend! (i.e. changing cursor color)
There seems to be no event for that in my event structure (although there is a event for changing the plot properties through the plot legend).
I'm using LV2009SP1.

I need the recognize any change of the cursor props made by the user. Like that:
Watching the cursor-Property for a change would be no help because there are automatic changes that I do not want to catch.
Something similar to the plot attribute change event in an event structure would be most helpful:

Update photo names in the library?

Hi all,
I've added all my pictures to iPhoto, but now they appear only with their name (eg. IMG_001, IMG_002 etc.) and i don't have any way to split them into single albums.
On the drive all photos are categorised in folders, for example
TRIPTO_USA_07/IMG001,
TRIPTO_USA_07/IMG002, etc.
I've tried to create smart folders, but the rules (eg. the "FILENAME CONTAINS") don't work because they are not able to recognise folder names.
I thought i could use a Batch renamer to modify all the names of the original pictures (eg. "TRIPTO_USA_07_IMG001") so I would be able to apply rules, but I need some way to update the library with the new names so that the rules can work.
any ideas?
thanks
Patrick

NoBack:
Welcome to the Apple Discussions. As PTash mentioned if you imported your photos by dragging the folders they were in into iPhoto (or selecting those folders from the File->Import menu, they are in rolls that will have the same title as the folders. Make sure you have By Rolls selected in the View menu. Then you can create smart albums based on the roll/folder name. Or you can select a roll and do a batch, sequential rename of the files in that folder to whatever you want.
HOWEVER, those new titles will only be in iPhoto. The original files inside the iPhoto Library folder will still have their original file names. If you need those files to have the file name then you can export them to the Desktop via the File->Export->File Export menu route and use the Use Title option.
This will give you files titled "file name-1.jpg", etc.
OR:
Add the photos to an album that you've named like you'd like the files to be and export but with the Use Album Name option. This will give you files named "Album name-01.jpg" which will sort better than the other way. If you have more than 99 files exported this way then the natural order listing will only be good for the first 99.
If you still have the original photos in their folders you can uses a renaming application like R-Name to batch, sequential rename the files, with the proper zero padding before the number, and then import into iPhoto (or a new library). That's what I do as a routine. Upload to an appropriately titled folder for that shoot on the desktop, rename the files with the date and brief description and then import. A little work up front saves a lot of issues later on.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

How to adjust plot names visibility in the legend of a XY-graph automatically

The solution is actually a bit more complex than you may expect, since you have to change both the plot and the plot characteristics. Attached is something that should work, although it is not very optimized and has some momentary, expected, display glitches.
I do not have LabVIEW 2009 on my development computer, so I edited it in LabVIEW 2011 and saved for previous. I don't think I used anything new, so it should work. Let me know if you need more info.

Can I detect a plot name change event in a plot legend?

I'd like to update a configuration file if a user changes the name of a plot in the plot legend.
The events I see for plots are: value change, autoscale range change, plot attribute change, and scale range change.
Plot attribute change does not seem to include anything that looks like plot name, and the others obviously don't contain that info either.
Is there any way to grab this event?
Thanks.

Jordan,
First off, remember that there is no single way to code anything, so I can offer one possible solution for you, but it is definitely not the only one.
LabVIEW does not have a property to check if the name has been changed through an event structure, but you can create your own events that LabVIEW can read. I found this really good document that might help you. Read through this and mess around with it and see if it gets you anywhere: Creating User Events
Once you get it to trigger the proper case, then its just getting that case to update the file you would like.
Another possible workaround, although not ideal, is to create a string control and have that be on top of the plot name. You would be able to then produce an event from that string changing value.
Hope this helps.

Waveform Plot Name in Legend Reverts to default even if I change it with a Property node

I have a waveform chart where I am trying to name the plots different titles, so that they appear in the plot legend with a meaningful name, rather than 'Plot 1', 'Plot 2', etc.
However, no matter what I do, if I try to change plot 0's name to anything, the plot name changes for a split second, and then reverts to the name that it originally had. I can succesfully control the names of the other plots, but not plot zero. I have enclosed the VI with the graph control, which I cut and pasted from another VI.
It seems that the properties of this control (though it is not a custom control) are set, and that these settings take precedence over the Propery Node Instructions. Is this a bug, or am I missing something.
Try it for yourself.

Ignore attributes help says;
If FALSE (default), the plot names in the plot legend automatically adapt to the plot names in the dynamic or waveform data attributes. If TRUE, the plot names do not adapt to the dynamic or waveform data attributes. Change this property to TRUE if you want to change the plot names. This property applies only to graphs and charts with dynamic or waveform data.
Trying to help,

Programmatic legend plot name display

All,
I'm writing a VI that displays multiple wave forms that are calculated from data that is read in from multiple .csv files. Each data file provides data for 32 plots. I have it set up to read in anywhere from 1 to 10 data files, and am using "strip path" to name the data in the legend via property node "ActivePlot -> PlotName" in a loop. So I have anywhere from 32 to 320 plots on my xy graph with anywhere from 1-10 plot names(32 like filed plots get the same name).
The Problem:
I only need to the display one plot name for each data file in the legend (i.e. plot 0 for each data file), but the legend is linear in that it displays plot names in the exact order of plotting. Outside of completely reordering the plot array, does anyone know of a more elegant way of coercing the legend to display only specific plots? I can't find anything in property nodes that does this and haven't stumbled on this problem in the forum (hopefully I didn't miss it).
Thanks in Advance!

Although you are not using the waveform plots you could still employ a similar approach.
Your data is an array of clusters where each cluster is a data set and a set of properties like string name, int color, enum y-axis....
when you lopt your data, use a subset of the array containing only the clusters you wish to plot, then use these extra fileds to adjust the plot index properties. Although this requires programming, you can make it very scalable (ie add new mata data fields to your cluster and add code to use them) and use the power of the original plot ledgend (that has huge number of features that would be hard to replicate).

Sometime the cursor name are superimposed on its cursor, does it exist a solution ?

when i save a XYgraph panel to a jpg picture , sometime ,some cursor name are superimposed on their cursor,maybe a refresh display problem, if you have any idea to resolve that bug ,don't hesitate thanks

Are you showing the cursor name (right click on the cursor legend and select show name)? How are you getting the XY Graph image? I ran a VI that uses the XY Graph invoke node and then the Write JPEG File VI to save the control as a JPG image. The cursor names are superimposed on the cursor only if I had selected to show the cursor names. Let us know a little more about what you are doing.

After updating to IOs 5.0, my contacts updated in name only, not the information. Has anyone else seen this?

After updating to iOS 5.0 on my iPad2, my contacts updated in name only, the information (addresses, phones, etc.) is blank. Has anyone else seen this? The cloud has all the contact information intact.

No, no replies yet. Fortunately, I have all my contacts backed-up on Google. I haven't lost the data, just need to merge into my iPad contacts. Good luck with your call to Apple.

Move the name of cursor (not the cursor itself) on the XY graph

I use cursor list property to overlay cursors on the XY graph, everything looks fine except that the name of the cursor and the cursor are at the same position, so it's hard to read the name of the cursor. Is there anyway to dynamically move the name of the cursor?

No, you cannot do this programatically, the cursor name position may only be moved manually when the Name is "Trackable" (when Allow Drag == TRUE). However, you can use cursors in pairs of two to accomplish this. Use the first one as a normal cursor and the second one only for the cursor name, making the line (Hair Style) and point (Point Style) invisible (=0). If you have multiple cursors, just treat them as pairs and multiple your index by two, when finding the index of the pair.
Good luck,
Jim

Why does notes remove the cursor when it updates

Hello Everyone,
I just downloaded the new Mountain Lion OS and I was excited about the syncing capability of the notes and reminders. After some effort I was able to get the notes to sync on my mac book and my Iphone. The problem is that after typing one work the bar at the top says updating, and it removes the cursor from the notes writing area. I have to click to get the cursor to appear again and then continue typing my note. This happens so frequently that it pretty much makes the app too annoying to use. Has anyone else run into this issue? Have any suggestions?
Thanks,
Scott

Scott,
Hopefully, it's just a transient problem with the iCloud account. You might wait awhile and see if it goes away.
If it does persist, you might want to get in touch with iCloud support to see if they can shed any light on what the problem might be. To me it seems like the problem is on their end, not yours.

Cursor legend for waveform chart

Greetings again. Is there a method to turn on the cursor legend in a waveform chart (like in the waveform graphs)? I'd like to allow a user of my application to be able to select a portion of a chart and have the application report the value plotted.
I am acquiring data via the Analog In channels of a PCI-6036e at 1500 Hz to plot in real-time. I tried plotting my data with the waveform graph but it only shows the latest readings and does not scroll the data. I know I could build an array and rotate through it as the data comes in but that seems like a lot more effort just to be able to use the cursor controls to highlight data.
Any ideas? Am I being too brief?
Thanks-
-dennis.
