MATLAB: How to rotate plot using code

image acquisitionimage analysisimage processingplotplottingsubplot

I have a plot showing pixel intensity values. I want to rotate the plot clockwise 90 degrees…can anyone help

let y is pixel intensity

x=1:1:length(y)

plot(y,x) may work instead of plot(y)

this command is useful to flip axis

set(gca,'YDir','reverse');

u can use this command too

camroll(-90)

ax = gca(); 
ax.XDir = 'reverse';
% or 

ax.YDir = 'reverse';

To flip the data vertically rather than the axes,

scatter(x, fliplr(y))  
% or 
scatter(x, flipud(y))

 x=-2:0.1:2;
 y=exp(x.^2).*cos(20.*x);
 plot(y,x)
