Question

I would like to make a log-probability plot for my data. I looked up the probplot function and wrote this code

x = [0.3,1, 2,5, 2];
probplot('lognormal',x)

I would like it to show the grid lines like this plot

and also relabel x-tickmark at 0, 1 (instead of 10^0), and 100

Thank you for your help!

Answer 1

There you go:

x = [0.3, 1, 2,5, 2, 12 25];
probplot('lognormal', x)
grid on
ticks = arrayfun(@num2str, get(gca, 'XTick'), 'UniformOutput', false);
set(gca,'XTickLabel', ticks)

Hope that helps 🙂
