Dynamic display of Y-axis on XY graphs

[lraynal]

Dear all,

I'm trying to debug a LabVIEW 7.1(.1) bug with the Y-scale(s) when autosizing and hide/show.

I saw one topic under the NI forum related to this trouble, but dated in 2004, and without any complete answer... Just ideas !

The bug is: I have a XY Graph. When I change the range of the Y-scale, then hide it, and then autoscale... If I show it again, it sometimes (for not saying frequently !) has moved from the normal position... Like this:

Here is a simple code to repeat this behaviour:

One idea to avoid (a little bit!) this problem, is to show the scale before changing the range (when we auto-scale it) and then hide it again. We see a flickering, but that's almost working...

I just can add that in 8.2 the hide and show of the scale is not moving the width of the Graph... Probably because of this recurent problem since a long time !

Does someone has ever encounter this "old" bug, and has a better idea to solve it?

For information, in my real program, I have 6 Y-scales for 6 plots, and I need to change the width of the Graph depending on the number of plots I want to see (i.e I don't want a "small" graph if I'm watching just one plot!)

Thanks for your help.
