#Gnuplot normal distribution generator#

Some graphics drivers are included in the normal distribution but are not built by default. I plotted the values using gnuplot using the 'smooth freq' command. The source distribution ('gnuplot-5.4.0.tar.gz' or a similar name).

#Gnuplot normal distribution generator#

The other settings in the file define the width of a single bin plotted as a box and its fill style. I have written a random number generator that produces numbers with a Gaussian distribution.

Hist = 'u (binwidth*(floor(($1-binstart)/binwidth)+0.5)+binstart):(1.0) smooth freq w boxes'įor a detailed discussion on why calculates a histogram you should have a look at this discussion and the documentation about the smooth freq which basically counts points with the same x-value. # define macro for plotting the histogram The content of hist.fct, including the definition of looks like this The macro is defined in an additional file hist.fct and loaded before the plotting command. The functions in gnuplot are the same as the corresponding functions in the Unix math library, except that all functions accept integer. Lets say youve written a random number generator that produces numbers with a Gaussian (i.e. They were both given as one dimensional data and plotted with a defined macro that is doing the histogram calculation. 1 you see two different distributions of measured angles. ( code to produce this figure, hist.fct, data) 1 Two different distributions of measured angles.
