How do I get the coordinates of a fit line using makedist

I'm plotting a lognormal distribution where I use the command

[fit confidence] = lognfit(censoredFailTime,[],censored);

to fit a data set and then get the mean and standard deviation using

fitplot = makedist('lognormal','mu',fit(1),'sigma',fit(2));

To plot the data I'm using

plotprob = probplot('lognormal',censoredFailTime,censored,'noref');
probplot(gca,fitplot)

but I also want to extract the coordinates of the fit line as they appear on the graph. How can I get these coordinates from this?
