I found that the layout of secondary desktop is different from the primary desktop. I configured "Axis Precedence " as “North/South” while the layout of secondary desktop seems like “East/West”. Is it a bug or is there any configuration on it? I use Ignition v7.9.7.
Try changing the layout to Anchored
The axis precedence (and a few other project-level settings) don’t inherit correctly on secondary desktops. That bug has been fixed in a future release (probably 7.9.11). If you get in contact with support, they can get you set up with a workaround - it’s a little “hacky” and there are caveats around it, so I don’t want to publicly post it here.
