Show calibrated value as acquiring

Hello, I hope someone good at Matlab can help me on this issue!
What I can do so that the data in "getdata" is calibrated? What I mean is, can the scope show the units that i want instead of volts? I want to see the real time plot with the actual unit (mmHg, in my case), not volts!
thank you so much!

You need to tell us more about what kind of device you are reading from and which interface driver you are using to the device.

I would suggest using getdata() with 'type' 'native', shifting the resulting integer up so that the lowest possible value is 1, and using that as an index into a lookup-up table of calibrated values (I'm assuming the voltages might not be linear response.) I don't know at the moment how you would change the legend on the scope.
