Plot: vertical legend for x axis

I have the horizontal legend for x-axis as you see in the attached graphics. But in this way numbers are hard to see. I would like to set the legend to be vertical to improve readability. Please advise.

See if you can use the 'XTickLabelRotation' (link) ‘axes’ property. (I do not remember when this option first appeared. I believe it was R2015b.)

Would you explain how it works in the following example?

w=0:0.05:1;
ncount1 = histc(x(:,1),w);
relativefreq1=ncount1/NSamples;
ncount2 = histc(x(:,2),w);
relativefreq2=ncount2/NSamples;
ncount3 = histc(x(:,3),w);
relativefreq3=ncount3/NSamples;
figure (4) 
plot(w, relativefreq1)
hold on
plot(w, relativefreq2,'LineWidth',1.0)
hold on
plot(w, relativefreq3,'LineWidth',1.5)
legend('Data1','Data2','Data')
title('Distribution of Data')
xlabel('Data')
ylabel('Frequency')
xlim([min(w) max(w)])
set(gca, 'xtick', w)

Tweak the last line to be:

set(gca, 'xtick', w, 'XTickLabelRotation',90)

Thank you.

As always, my pleasure.
