评论： the cyclist 2021-10-18

I am trying to plot two variables (like speed V_a, & V_b of two cars) versus time. I am trying to use same axis range for both V_a and V_b over the same interval of time. I want to keep both y variables in the left side. But, all I am trying is here distinguishing two plots with differnt color and mentioning name of both speeds in y axis. Please suggest me.

Not sure what you mean about "mentioning both speeds in y axis". A more conventional method would be to use a legned. Does this work for you?

% Some pretend data

t = 1:0.05:5;

V_a = t;

V_b = t.^2;

figure

plot(t,V_a,t,V_b)

xlabel('Time')

ylabel('Speed')

legend({'V_a','V_b'},'Location','NorthWest')

I was trying to keep both V_a and V_2 in place of speed but looks like I can write like below. The y varaibles i.e. Tumor volume and Carrying capacity have same dimension but have different meaning so I don't have a single replacement like 'Speed' for both of them. Still, I utilized your idea like below.

Thank you!

.............................

plot(t,V,t,K)

xlabel('Time (days)')

ylabel('Tumor Volume/Carrying Capcity (mm^3)')

legend({'V','K'},'Location','NorthWest')

A different approach that displays the same information would be

% Pretend data

t = 1:0.05:5;

tumorVol = t.^2;

carryCap = t.^2/2;

figure

plot(t,tumorVol,t,carryCap)

xlabel('Time')

ylabel('Volume [mm^{3}]')

legend({'Tumor','Carrying capacity'},'Location','SouthEast')

You'll need to decide what will be clearest to your audience.

[Note that I also showed here how to change the location of the legend to the lower-right corner, and how to use an exponent for mm^3.]
