How do i plot probability density plot with actual values?

How do i plot probability density curve with actual values as vertical line (as the picture attached)? And how to interpret that according to the distribution? Thank you.

You are really a great help. I have studied your other answers which are very helpful. Thanks a lot.

If the distribution function is provided, along with the necessary parameters (none of which are prrovided here), this is straightforward —

x = linspace(1500, 2100);
mu = 1800;
sigma = 75;
npdf = normpdf(x, mu, sigma);                               % Use Normal Distribution To Demonstrate

npdf = 1×100

0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0001 0.0001 0.0001 0.0001 0.0001 0.0002 0.0002 0.0003 0.0003 0.0004 0.0005 0.0005 0.0006 0.0007 0.0009 0.0010 0.0012 0.0013

figure
patch([x flip(x)], [zeros(size(npdf)) flip(npdf) ], 'b', 'FaceAlpha',0.25)
hold on
plot([1 1]*mu, [0 normpdf(mu, mu, sigma)], '-r', 'LineWidth',2)
hold off

Experiment with the intended distribution function and parameters.
