Graph property node

[Frida]

Hi,

I have seen in an old program that a property node for a graph, containing two elements called "XScaleInfo" and "YScaleInfo" are used. In newer versions of LabView these elements aren't available. Is there some one else that I can use. If it is possible, I would like to "carry on" the whole graph, with data, x-scale information, y-scale information togehter, is that possible?

Thank you!

Did you look at the "X Scale" submenu when you right-click on the Property node? What specific piece of the "XScaleInfo" do you believe is missing?

"XScaleInfo" and "YScaleInfo" disappeared as available properties in LV6, but they were just clusters of various settings which are now available individually (under XScale> and YScale> ) .  Some of the settings have been expanded and some have been renamed.

Yes, you can use them to make one graph look like another.

This problem has escalated. 

If you have ported code forward with this old property node reference to an xy chart (xscaleinfo), the code continues to work up through Labview 8.0.2 with no complaints.  If you port the same code to Labview 8.2 and try to execute code with the xscaleinfo property node, Labview crashes!  It took considerable digging to find the offending bit of code.

Most annoying!

RMF,

I have verified this behavior with the xscaleinfo and yscaleinfo crashing LabVIEW if called in 8.2 while working on a support issue from another customer and wanted to let you know that I've filed a Corrective Action Report with R&D to fix this behavior in a future release. And yes, it took me a considerable bit of digging to find what was causing the code I was working on to crash as well.

Could you please post the CAR#?

Ben,

Sure, its 4467K954.

This was reported to R&D (# 4467K954) for further investigation. Thanks to all for the feedback and for helping make LabVIEW a superior product!

Hi

Im having exactly these problems ur discussing when trying to use VIs created in LV 6 in LV 8.2.

It's not I who have written the program but I have managed to locate the Xscaleinfo and Yscale info front panels in one of the sub .vi ..... The problem is that in this VI I cant switch into block diagram view, and Im not sure how to switch to start using the new properties Xscale and Yscale.

I have read the problem solution: Reading or Writing the XScaleInfo and YScaleInfo Graph Properties Crashes LabVIEW ( http://digital.ni.com/public.nsf/allkb/E25510355D0D4788862572460005B4E0 ) but im not sure what to do.

I would be very grateful for any help

Cheers

I also forgot to mention that we changed from a PCI card with GPIB into using a a USB GPIB interface at the same time as we migrated the software to our new machines and new version of labview (6.0 --> 8.2 and 7.1 --> 8.2)

Hope someone can help me.

Cheers again
