set the tick format of y axis

How can I set the format of the ticks of the y axis?

I want to change the upper one to the lower one, as the former is too wide in space.

Hi @min lee, you can use 'ylim' function to set upper and lower bounds of the y-axis in a plot:

dat = 0.008*rand(1, 5); % Sample random data
plot(dat)
ylim([0 0.008]) % Set any arbitrary limit

Here's a compact plot, with suitable limits:

plot(dat)
ylim([min(dat) max(dat)]) % Set compact limits

In the Numeric Ruler Properties documentation, see the section on Exponent.

x = linspace(0, 1);
y1 = sin(2*pi*x);
y2 = cos(2*pi*x)*1E-2;

figure
yyaxis left
plot(x, y1)
yyaxis right
plot(x, y2)
grid

figure
yyaxis left
plot(x, y1)
yyaxis right
plot(x, y2)
grid
Ax = gca;
Ax.YAxis(2).Exponent = -3;

Experiment with your own data. Note that you will have to specify the second y-axis to use it with your plot.

If I had your data and code, I could do this directly using them.

set(gca().YAxis,'Exponent',-3)

See ytickformat and also the Exponent property of axes; https://www.mathworks.com/help/matlab/creating_plots/change-tick-marks-and-tick-labels-of-graph-1.html#SpecifyAxisTickValuesAndLabelsExample-5

Hello @min lee,

You can achieve the desired xtick format in MATLAB. In order to demonstrate this consider the code:

% Here, I will demonstrate how to express the xticks and yticks in exponent form.
x=100:100:2000;
y=100:100:2000;
plot(x,y)
ax = gca;
ax.XAxis.Exponent = 2;
ax.YAxis.Exponent = 2;

You can refer to the following link to get more information:

I hope it helps!
