How to convert highest points of histogram into a simple line graph

I want to plot a line graph by simply connecting the highest points of each bar. In other words according to figure data I want to plot the frequency of theta in the form of connected line instead of bar. Kindly suggest. Secondly I want to do this because I want to plot multiple data on a single figure for comparison purpose, any suggestion how it can be done in a more presentable way if I have following type of several data.

Huh--I answered this early this AM but it seems to have not "stuck"---

Use the histcounts function with defined edges vector for bins and the plot the results...

edges=linspace(1,160,31);         % pick number of bins, points is 1+ that over your range
N = histcounts(X,edges);          % get the counts in those bins
x=filter(edges,[0.5 0.5],1);      % midpoint of bins; mean of edges
plot(x(2:end),N)                  % and plot...N.B. start with second x to get number bins wanted

Thanks a lot dpb!

Perhaps semantics has changed over the years, but at least in 2018a, the third line should be 'x=filter([0.5 0.5],1,edges)'
