How to connect a large input/output timeseries signals using root inport?

I need to connect input signals to my model on simulink. I figured that to do so I have to convert all the data into timeseries signals and use root inport mapper.

From the root inport mapper, I opened the signal editor and visualized my two inported signals and found them squeezed and streched at different time instances.

The original data that I want to inport in my model.
