Display problem when a ring control is selected during plotting on PDA

[Shuba (Sunlux)]

Hello,

    In a PDA Appln. screen, on the top portion of the screen, there is plotting of some data on a chart. On the bottom portion of this screen, there is a ring control. When we try to change some setting using the ring control, the control's pop-up list is "swept along" with the graph. I hope i have made myself clear of the problem. Has anyone come across this problem before? Is there a solution?

Thanks & Regards,

Hi,

I am really not clear about the "swept along" part. Is there any way you can post your VI so I can take a look at this?

Hello Eli,

    Thanks for ur response. I have created & attached a sample VI which clearly shows the control's pop-up list being "swept along" the graph problem, when the Ring control is selected on PDA. Please note that this problem is not there on desktop. We are using an "acer n300" Windows Mobile 5.0 PDA. Expecting a solution from u...

Note: Version of LabVIEW that we are using: LabVIEW 8.5 Professional Development System for Windows Vista/XP/2000 and LabVIEW 8.5 PDA Module for Windows Mobile.

Thanks & Regards,

Subhashini,

I have looked at your code and I do in fact see what you are seeing. This is incorrect behaviour and I have filed a Corrective Action Request to R&D. The CAR ID# is 99823.

On another note, when you expand the ring control it overlaps the Plot. We recommend that you do not have controls that overlap each other. This can conpromise the perfomace of your program because the display has to be updated more often.

Hello Eli,

    Thanks for ur response. The ring control & the Plot are placed that way because of space constraint on PDA. Reg the 'getting swept along' problem, is there any work-around?

Thanks & Regards,

Subhashini,

The only work around that comes to mind, considering the space constraints, I would use a Tab Control and put the graph on one Tab and the Ring Control on the other one. Along those lines, having the control be swept along while it is selected does not affect the functionality of the program or the control. Maybe you can just have the control swept a few times while the user selects a new option.
