19.7 To define a
datum
Once raw data are known, the first step consists in setting a datum. For this explanation we
will continue with our previous example.
1. Select one of the raw data blocks (C1 for instance). For this, you can either click on the
wanted block from the touch screen or use the keyboard arrows buttons.
Note that the selected block has a (1) nearby its name and that the corresponding circle
has become blue in the graph.
Selecting a bloc (blue rectangle) implies the corresponding element
becomes blue in the graph.
The available options (linked to the selected blocks) are displayed in the bottom screen bar.
In our example, when a unique point or a circle is being selected, only this option is available.
It is the option that allows to set a point or the centre of a circle as reference/origin.
2. Press
.
All coordinates have been modified according to the new origin that we can see in the current
datum status bar. C1 is now the new origin.
