How to make two coordinate X axes in single plot

Hello, I would like to have a single plot with 2 linked X axes with different scales. Currently, I have plot with 2 axes (first in time, second in samples) with significantly different scales, however with same number of points - see attached plot.

I want both axes to zoom simultaneously and proportionally, if I use linkaxes it changes scale on one of the axes, which is problem given the difference in scales. Can you recommend me any solution? Thanks

Okay, my problem was solved by creating quite simple auxiliary function. Detailed description can be found on

Can you please share your solution?

And another question, how to make plot show double axis with all the points?

plotxx() ?

Thanks for quick response! However I don't see this as a solution, since this, just like my original solution (without linkaxes) zooms only one X axis, the other stays as it was. I would like to see, when zoomed, sample range and time range at the same time.
