How to change the unit of an attribute at runtime

# 4 years ago
flanglois	Hi all, Anyone knows how to change the unit of an attribute during runtime? thanks for helping, regards, Florent.

Reynald	Hi Florent, An easy way is to start an atkpanel on your device and to click on the "…" button at the right of the attribute you want to change the units. Then you can refer to the Tango documentation for the meaning of the parameters: https://tango-controls.readthedocs.io/en/latest/development/advanced/reference.html#general-purpose-parameters You can also change it from jive by expanding your device node and then click on "Attribute config" in the tree. Then you will have to select the Unit tab on the right. Hoping this help, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.
