Hi,
This is my current script. I would like to fit a curve to a histogram as shown in the picture below: What lines should i add to the existing script?
yA = randn(1000,1)*7+15;
yB = randn(1000,1)*3+7;
yC = randn(1000,1)*4+30;
% specify number of bins and edges of those bins; this example evenly spaces bins
NumBins = 25;
BinEdges = linspace(0,50,25);
% use histcounts and specify your bins
cntA = histcounts(yA,'BinEdges',BinEdges);
cntB = histcounts(yB,'BinEdges',BinEdges);
cntC = histcounts(yC,'BinEdges',BinEdges);
% plot
figure(1); cla; hold on;
% convert bin edges into bin centers
b = BinEdges(1:end-1)+diff(BinEdges)/2
% use bar
bar(b,[cntA',cntB',cntC'],'stacked')
