How to set plot axes?
显示 更早的评论
figure (1)
plot(A(512,:))
hold on
plot(B(512,:),'r')
How do I specify the axes scale for plots? E.g. Y axes from 0 to 80000; and X axes from 0 to 1100

axis([0 1100 0 80000])

Normally it is chosen automatically, but you can set the axis XLim and YLim properties.
Note: you ask for x to be 0 to 1100, but you are using the single-input version of plot(), which will default x to be 1:length(Y) and thus will start from 1. If your x should start from 0, then you should be using the two-input version of plot,
plot(x, A(512,:))

A related question is setting the exact time to x-axis. For example, how to set the time as say, 04:30:00, 04:35:00 and so on along x axis and frequency as 45 MHz , 50 MHz and so on up to 450 MHz along y-axis.

set the xtick and ytick properties, and use datetick() on the x axis with the option to preserve ticks.
You would need to calculate the tick locations, perhaps using add2date()
