Dear all,
i have my y-plot in the number of steps what matlab computed. But I want it in seconds how do I plot it?
I mean matlab showing from 0 to 4*10^5 in my y-axis but I want to plot in 0 to 14,000 seconds in my y-axis?
I did it manually like assigning a tickmark and setting the time values but it doesn't work out when I zoomed just like half of my data... I have the values of seconds computed in a text file is that anyway possible to implement that seconds into the graph what I have ?

Matlab assumes the x-axis values 1 to 4e5 (not 0 to 4e5) automatically:
y = rand(1, 4e5);
figure;
plot(y);
But you can specify the x-axis values easily:
figure;
plot(linspace(0, 14000, numel(y)), y);
No need to define tickmarks manually and no problems at zooming.
If you have problems with plotting, "help plot" and "doc plot" will be very helpful.

Of course you can import the x-axis values from an Excel sheet also instead of using LINSPACE.
I do not understand the question about the "depth". Please post a small example.

@Elavarasan: Are you satisfied by the answer or do you have further question? Can you explain the "depth" related question again?
