The accuracy of the result is limited by the bin width.

This function finds the indices of the bin containing the minimum value in the histogram h and stores the result in ij. The values of the histogram bins are reset histotram zero. This C library would try to make system calls using the OS X system call numbers and calling conventions. This function returns a pointer to a newly created histogram which is an exact copy of the histogram src. This function reads into the histogram h from the stream stream in binary format.

This function finds the indices of the bin containing the maximum value in the histogram h and stores the result in ij.

This function returns the contents of the ij -th bin of the histogram h. This function frees the two-dimensional probability distribution function p and all of the memory associated with it. Then a few sample points are added to the histogram, at 0. This function sets the ranges of the existing histogram h using the arrays xrange and yrange of size xsize and ysize respectively.

gsl-histogram(1) – Linux man page

This function returns the mean of the histogrammed variable, where the histogram is regarded as a probability distribution. The following program shows how to make a simple histogram of a column of numerical data supplied on stdin. Header states merely the interface that is exposed by this histogfam. It worth noting that Gnuplot is actually very powerful tool, so invested time into reading its documentation will certainly pay off.

OK, thanks sarnold, I guess I was hoping for too much. The search includes an optimization for histograms with uniform ranges, and will return the correct bin immediately in this case. It’s been a while.

If you want to include these values for the side bins you will need to add an extra row or column to your histogram. These functions return the maximum upper and minimum lower range limits and the number of bins of the histogram h.

This function allocates memory for a two-dimensional histogram with nx bins in the x direction and ny bins in the y direction. You cannot copy libraries from OS and expect them to work unchanged. In this equation is the number of events in the bin which containsis the width of the bin and is the total number of events. The following plot shows the distribution of the simulated events.

In this equation is hisyogram number of events in the bin which containsis the area of the bin and is the total number of events. I was just updating my answer. This function uses two uniform random numbers between zero and one, r1 and r2to compute a single random sample from the two-dimensional probability distribution p.

This function returns the standard deviation of the histogrammed y variable, where the histogram is regarded as a probability distribution.

It can be shown that by taking a uniform random number in this range and finding its corresponding coordinate in the cumulative probability distribution we obtain samples with the desired probability distribution.

The library provides functions for reading and writing histograms to a file as binary data or formatted text. So I think the you’d better just install it hisgogram your machine. Using a higher resolution grid we can see the original underlying histogram and also the statistical fluctuations caused by the events being uniformly distributed over the area of the original bins.

Allowing for statistical error, the height of each bin histoyram the probability of an event where ,: Here is an example of the program in use.

histgoram Since the upper limits of the each bin are the lower limits of the neighboring bins there is duplication of these values but this allows the histogram to be manipulated with line-oriented tools.

This function returns the contents of the i -th bin of the histogram h. This function uses ra uniform random number between zero and one, to compute a single random sample from the probability distribution p.
