Moving and scaling

|
^^^^^^^^^^^^^^^^^^
|

|
|
|

|
|
Values are always used and displayed in scientific notation *x.yyyyez* where x is a signed single digit larger than 0.
|
||
|
|
The relative stepsize (by default 0.0001) increases or decreases is always of the same magnitude as the current value, e.g.,
|
||
|
|
1.2345e0 changes by 0.0001, but 1.2345e20 changes by 0.0001e20.
|
||
|
|
If the step results in a new order of magnitude the value will be adjusted accordingly, i.e., a step from 9.9999e1 to 10.0000e1 will become 1.0000e2.

This behaviour leads almost always to values different from zero when using the arrow buttons. Please enter it directly to get a value of zero.

Boxes :guilabel:`log x` and :guilabel:`log y` change the respective axis from a linear to logarithmic scaling and vice versa.

Every selected set will be recalculated according to :math:`new = scale \cdot old + offset`.
