Mixed Signal Graph - view on x-axis

[Joachim082]

Hi

After updating my application to LabVIEW 9.0 I have troubles with the display of my mixed signal graph. I've attached an examplw that should illustrate the problem: Although there are no more data on the x-axis the time range isn't exactly limited via the timestamp array. Before and after the x-axis is extended which centers and deforms my graph.

Is the Strictly Type of the Control the problem? When I use a new Mixed-Signal Graph Control from scratch everything works fine - why I have the problem when I use absolute time.

Regards,

Hi Joachim,

I'm able to reproduce your problem. At the moment I don't know why the 8.6 und the 2009 signal graphs behave in a different way, but the development engineers know already therefrom.

Does this problem still exist, or did you find a workaround? Using property nodes would be a way to dynamically adjust the X scale minimum and maximum.

Please let me know, if that helps you to adjust the graph the way you need it to.

Sorry for not having a better solution at the moment.

Kind regards,

Patrick

Patrick,

Yes I've a workarround with the min and max (with range) but when I zoom in the mixed signal graph the steps on the x-scale should also dynamically adapt but therefore I have to react on the event.. this is a neverending story and in my opinion the mixed signal graph should handle this events on his own with correct behauviour.

Hi Joachim,

After speaking to the developers, it turns out this is a known issue for 2009. So R&D is aware of this problem.

What you should do is keeping up-to-date with the patch releases. Until then, you will have to use the work-around methods you've mentioned above.

Please feel free to respond with any additional questions you might have on this issue!

Cheers,

Patrick
