Dear MATLAB users,
I have a histogram data derived from the following codes:
figure; stem(bwhist, counts2)
The histogram produces a result like this: http://s7.postimg.org/mo9hvo2zv/image_1.png
I would like to curve fit the histogram using histfit function.
figure; histfit(counts, length(bwhist))
and I also had tried this code:
figure; histfit(counts, [])
The result of my second attempt is: http://s23.postimg.org/f5tgs1rcr/untitled.png
As you can observe from my two attempts result, the histogram x axis, y axis are wrong.
I would like to achieve the curve fitting based on my original histogram image.
Could you highlight which steps I have missed when I am using "histfit" function? Or which built-in functions do you suggest?
Thank you.

Clicking the links returns The page you were looking for doesn't exist. However, copy&paste works. Have you used "<<url>>"? Should be "<url>" without citation marks.

There is an excellent guide with examples for Histogram Adjustments in MATLAB here: http://imageprocessingblog.com/histogram-adjustments-in-matlab-part-i/

There appears to be a continuation via WordPress, but this also references the defunct GoDaddy site for part 1.
