Bug report #11920

Updated by Giovanni Manghi about 3 years ago

Within Print Composer, SCALE changes when changing XMIN or YMIN for a map, which makes it difficult to accurately draw a map. Changing SCALE alters XMIN, XMAX, YMIN and YMAX. Behaviour is inconsistent, as changing YMIN or YMAX does not effect SCALE.

To reproduce the problem, change XMAX either by changing the Item Properties of the map, or by dragging the boundary of the map.

The parameters XMIN, XMAX, YMIN, YMAX, SCALE and the size parameters WDITH and HEIGHT are all entrancingly linked. What is required is the ability to fix some of the parameters, such as XMIN, YMIN and SCALE and let the other parameters adjust accordingly. Ideally the user should be allowed to choose which parameters to fix and which to allow to float.
