How to change X axis in the form of percentage

In this plot i want my x axis in the form of percentage value where it's range start with [77,146], 77 as 0 and 146 as 100%, without changing curve's y axis

Try something like this —

x = linspace(77, 146);
y = -60 - 15*sin(2*pi*x/50);

figure
plot(x, y)
Ax = gca;
xt = Ax.XTick;
xtnew = (xt - min(xt))/(max(xt)-min(xt)) * 100;
Ax.XTickLabel = xtnew;

.

I'd use normalize rather than performing the calculations myself.

x = linspace(77, 146);
y = -60 - 15*sin(2*pi*x/50);
figure
plot(x, y)

xt = xticks;
normalizedX = normalize(xt, 'range', [0 100]);
xticklabels(normalizedX)

@Steven Lord — Thank you! I’ve used normalize (introduced in R2018a), however I didn’t think of using it here.
