Please help!

I use LV 5.0
I use the chart to show 4 chanals from my DAQCard.
If i am using attribute nodes to change the min and max of the y scale, the
data in the chart is not replotted to reflect the new scale . The attribute
nodes are not immediately updating the chart (only upper chart is
replotted). And only stop the programm and make "Stak Plot" and "Overlay
Plot" is make effect to all chanals.
How can I fix it?
Is any other way for this?
Thank You.

Hi,

There is a problem in trying to set the min and max values of the y scale of the Plots 1 to Plots n. Basically it doesnt work. I reported this problem to NI the middle of last year.

I havent tried LabVIEW 6.0.2 to see if the problem has been corrected. There isnt a fixe in labview 5.1.1.

Any one else know the answer if its been fixed??

Hi everybody,

this is a very annoying problem. In LV 5 the only solution I found is to display data on different charts and change scales at the same time, it should look like a stacked plot chart.
In LV 6 ,and further, there is a solution, you should use the property: Active Y Scale.
This works both on stacket and overlayed charts.

I attach a sample vi that shows it.
