I want to calculate probability density for the same. I want a plot having event duration at X-axis and probability density at Y-axis. I have attached histogram for which I want to calculate PD. MATLAB supports plotting histogram feature that enables the user to create a bar graph for any vector or matrix and grouping the data into bins using an automatic binning algorithm. For each bin, the area represents the frequency of occurrence of the data, not the height. Note that if you choose the generic MATLAB Host Computer target platform, imhist generates code that uses a precompiled, platform-specific shared library. Use of a shared library preserves performance optimizations but limits the target platforms for which code can be generated. 1.3.

I couldn't see a simple way of doing this. You can get the histogram counts back from hist3 using [N C] = hist3(X); and the idea would be to normalise them with: N = N / sum(N(:)); but I can't find a nice way to plot them back to a histogram afterwards (You can use bar3(N), but I think the axes labels will need to be set manually).

As we know, 'hist' function in Matlab plots the histogram of an array. I need to know the numerical value of each bin. What is the density of the earth's The mean and standard deviation of the 1 ⇥ 5000 sums of dice values will be computed, and the probability density function of normal distribution (with the mean and standard deviation computed) on top of the relative frequency histogram will be plotted. I couldn't see a simple way of doing this. You can get the histogram counts back from hist3 using [N C] = hist3(X); and the idea would be to normalise them with: N = N / sum(N(:)); but I can't find a nice way to plot them back to a histogram afterwards (You can use bar3(N), but I think the axes labels will need to be set manually). If your data are from a small set of integers, I'd recommend to use one bin per number. For continuous data there is an alternative to the histogram, called kernel density estimation (ksdensity), and there exist algorithms to pick the optimal "bin width" (called bandwidth in that context).
The two key additions are as follows: 1) Use hold on and hold off to get the histogram and plot on the same figure. 2) Scale the output of normpdf to the appropriate size so it is on the same scale as the histogram. My function called DicePlot, simulates rolling 10 dice 5000 times.
