How to magnify y-axis to see plot more clearly

So I am averaging some signals over time, and plotting it to get the figure I've attached.

I want to stretch the y-axis in such a way that I am able to view the little curves at the start of the figure more clearly. I tried using ylim, but I get an error saying I have too many output arguments. Could I stretch the y axis somehow?

ylim returns the present axis limits as an array, so just use one return variable if you want to retrieve the existing limits (and, optionally, set new ones).

Looks like what would help more in this case would be to expand the x axis rather than y, though (altho both may help some)

xlim([0 10])

looks like would cover most of the initial transient period.

I also have a similar question.

Considering the same example, I want to strectch the y-axis from -0.5 to 0.5 but I also want to have the remaining y-axis labels i.e., i want to plot a graph with y-axis ranging from -1.5 to 1.5 but with stretched -0.5 to 0.5 axis range.

Though I can change the y-axis to log scale to highlight the variability between -0.5 to 0.5 range but it changes the appearance of the graph which I don't want.

Best!

I too have a similar problem...... if someone has resolved the issue kindly help me out.

Thank You.

You can use the axis function to define your desired axis. Or you can determine the thickness of your plot using the following functions.

axis([0,200,-1200,500]);
or
plot(time,amplitude, 'LineWidth', 5)
