[Qgis-user] Non Interactive Map Views or Static Scale Factor?

[Andrew Hughes]

Hi All,

When introducing additional map views, I was wondering if it were possible
to have the non-main map views set to be "non-interactive". I can't see
such an option anywhere. Alternatively, I think having the ability to set a
static scale factor might overcome my issue.

So, what's the issue? When "Synchronize Scale" is enabled on the non-main
map views. The scale factor on these jump around wildly when the user
interacts with them (zoom in/out). If I could just make the non-main map
views purely "shadow" the main view this would not happen. Effectively,
users can only zoom in/out on the main map view. Either that or force the
scale factor to hold a static value of 1.0.

Before zoom in/out on a non-main map view (and looking good):

After a zoom on the non-main map view, and now having a completely
different scale/extent to the main map.... only the center of both maps is
kept in sync. The scales are so far out of sync between the two

Help would be much appreciated,

Many thanks in advance
Andrew
