# Scales in sketch pad reset to zero in a different place

Hello,

I would like that the Scales (0,0) will be (0,0) where now it is (-600,0).

Or some other solution for getting an output of my cursor X as (0,0) where now it is (-600,0) at the sketchpad.

Hi matanel,

Would you mind giving a little more detail on what exactly it is that you want to accomplish? In particular, what is

`Scales`

supposed to mean?Maybe uniform coordinates could be useful to you.

Thank you Eduard,

I would like to ''log'' a variable that takes the variable ''correct_response'' and adds to it the value 600, and then takes the variable cursor_x adds to it the value 600, and then takes the new value of cursor_x and the new value of ''correct_response'' and does this : cursor_x - correct_response.

I want to have a column on the results file (csv) with this new variable of cursor_x - correct_response.

I know I need to program it on Python - how would you recommend doing it?

Hi Matanel,

I think I answered your question in this discussion

Let me know ( in that thread) if you need more help.
