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

barline graphmultiple dataplot

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

The reason is that you have a very sharply peaked histogram with a very long tail. The default binning, and your 20-bin option, just don't capture the range well. Try this:

figure
histogram(data,[0:0.1:5 Inf])
xlim([0 5])

I've defined the edges of the bins as a vector. The result looks like this:

You could request output from histogram():

h = histogram(S,'Normalization','probability');

and access properties such as h.BinEdges, h.BinCounts, h.Values, etc, described here.

Or you could use histcounts(), described here, after you plot your histogram:

histogram(S,'Normalization','probability');
[binCounts,binEdges] = histcounts(S,'Normalization','probability');
