[← Previous chapter](https://git.ad5001.eu/Ad5001/LogarithmPlotter/wiki/User-Manual:-Chapter-2) | Chapter 3: Positioning objects ([≡ Index](User-Manual))
# Positioning objects
Several objects that rely on position can be placed on the graph with your mouse using the "Positioning" interface. This interface can be accessed using the ![Position icon](https://git.ad5001.eu/Ad5001/LogarithmPlotter/raw/branch/master/LogarithmPlotter/qml/eu/ad5001/LogarithmPlotter/icons/common/position.svg) button that can be seen on certain object editing rows.
List of supported objects:
- Points
- Texts
- X Cursors¹

Click on the desired location to apply it to the selected object.
¹ Note: X Cursor only allow for X positioning so you will only see the vertical bar associated with it.
## Settings
There are two settings available on the interface:
The "Pointer precision" setting allow you to set the amount of digits of precision of the cursor. For example, a pointer with a precision digit of `2` will round all pointed position to `2` digits after the decimal point. Setting a precision to `0` will tound all positions to integers.
The "Snap to grid" checkbox rounds the selected position to the nearest intersection of the grid. It's useful for logarithmic scales when you want to quicly select a rounded logarithmic location at a few hundreds or thousands.
