Hı,

How can I draw the graph whose image I added? can you help me please?

The relationship between values is briefly,

drift ratio - displacement

displacement - base shear

I use the hold on command, but displacement and drift ratio are on the same axis (x axis).

How can I define separate axis like here?

I'm not sure about the requirement but you can define the relation bewteen them using the equation.

x2=(relation with x)*x;

Hope this will help!

Hi,

I understand that trying to plot two different y-axes for the same x-axis in MATLAB, you can use the yyaxis function. This allows you to create a plot with two y-axes, one on the left and one on the right, each with its own scale.

Here ia an example of how you can plot the relationship between drift ratio and displacement on one y-axis, and displacement and base shear on the other y-axis:

% Sample data

displacement = 0:0.1:10; % Example displacement data

drift_ratio = displacement * 0.05; % Example drift ratio data

base_shear = displacement * 2; % Example base shear data

% Create figure

figure;

% Plot drift ratio vs. displacement on the left y-axis

yyaxis left;

plot(displacement, drift_ratio, '-b', 'LineWidth', 1.5);

ylabel('Drift Ratio');

xlabel('Displacement');

hold on;
