How to scale the x axis ?

I have two plots from the same sensors. One plot is from target computre and one plot is from my PC. I want to scale the x-axis in such a way that they both look same. Please guide me. Thanks.

There's no way to scale the x-axis so they look the same. You can however manipulate the x-data in various ways. If you want to automate this process, then I'd apply variable translation and scale factors to the x-data of one series and then find the optimal parameters by minimizing the residuals. Perhaps this is a bit overkill.

plot(Time_vector,cyl_pos/1000) %Data from Target PC xlim([0 25]) hold on plot(pos.time/100,pos.signals.values) %Data from my PC

Thank you! This helped me a lot!

I am not certain what you want to do.

If you want to actually synchronize the signals, consider using the alignsignals (link) function, that I believe was introduced in R2016b. Another option is the dtw (link) ‘dynamic time warping’ function, introduced in R2016a.

First, you need to get the handle to the current axes:

h=gca;

This gives the handle to the current plot axes. Now you can modify the properties of the axes. To set the X axis limits use:

set (h,'Xlim',[xmin,xmax]);

One good way to keep track of plot handles is to assign them when you make the plot:

h1=plot(...);
...
...
h2=plot(...);

now you can manipulate the different plots:

set(h1,...);
set(h2,...);

Can you please tell me what should i write in h1=plot(. . .); ? Matlab gives me Invalid use of operator error. When i give some value

[Jim Riggs]

That is your plot command when you create the plot axes, e.g.

h=plot(Time_vector,cyl_pos/1000);
