LV 8.0.1 Autoscale X-Axis starts with an one hour window ?!?!

[Balze]

Hi LabView Experts.

I need a XY-Graph, that shows absolute time in X-Axis.

I want it to autoscale.

When i do so, i always get a window, that shows me one hour.
If i autoscale the same time in float, it behaves the way i want it to. Please have a look at the attached vi.

How can i get the XY-Grap to do want i want?

Any suggetions are apprechiated.

Regards,

Balze

P.S.: I know i can do this using propertie nodes on my own but i want to avoid that, because it's time consuming(increasing), when the data in the graph increases.

I am not sure if you can get away without using property nodes.  What do you mean by it is time consuming??

An easy way that I created a "window" of data, is to use the Xscale.min and Xscale.max property nodes.  you can format a control (or use a constant) with the formatting string %<%M:%S%0u>t and then select the number of minutes and seconds you want displayed.  Take the current time plus this number fed into the xscale.maximum terminal, and the current time minus this number into the xscale.minimum terminal and it will give you a nice window.  fyi, This will give you a window twice that of the time selected (select 30 seconds and it will give you a 1 min window)

Hi Kenny,

thanks for your reply.

My feeling is, that scaling a XY Graph via property nodes takes more time when i have more data in it. (Maybe I'm wrong here.)

Thanks for your hint with the "Easy way".
I allready have a very good solution for this (written in LV7.1.1) but this needs an XY-Graph that automatically scales. (I see, i have to rework this 🙂

But back to my first question:
Is there no way to get the autoscaling of a LV 8.0.1 XY-Graph behave like a LV 7.1.1 XY-Graph??

It works perfect with 7.1.1 !

Best regards,

I've got news.

I switched to LV 8.2 now.
And it works different than LV 8.0.1 !



But still autoscaling doesn't work like i expected.

So i think i've to say: "Goodbye autoscale!"
