Here's some example code on how to control the "ticks":
x = 1:5;
y = randi(100, 1, 5);
plot(x,y);
set(gca, 'ylim', [0 100]);
set(gca, 'ytick', 0:5:100);
plot(x,y);
set(gca, 'ylim', [0 100]);
set(gca, 'ytick', 0:25:100);
plot(x,y);
set(gca, 'ylim', [0 100]);
set(gca, 'ytick', 0:20:100);

Yes, but this is starting to sound like a different question. And we're commenting here in the answer box. Ouch!
But, to your point, yes, you can plot the data that appear in magenta from the right-side axis. They will have their own limits and will be fully visible. See Create Chart with Two y-Axes for details.

You can use the yticks and yticklabels functions to control the locations of the ticks and the labels used for those ticks.
x = 0:0.5:32;
y = x.^2;
plot(x, y)
Let's make a copy of that plot (so you can see the difference when I run the code in MATLAB Answers) and update the tick locations.
figure
plot(x, y)
yticks(0:50:1050)
Let's say I want to put ticks every 50 units but only to label multiples of 100.
figure
plot(x, y)
ticklocations = 0:50:1050;
yticks(ticklocations)
% Create the tick labels from the tick locations
% Or you could use
%
% ticklabels = yticklabels;
ticklabels = string(ticklocations);
% Replace the labels for any tick location that's not a multiple of 100
% with a blank label
ticklabels(mod(ticklocations, 100) ~= 0) = "";
yticklabels(ticklabels)
