Example: Gaussian Function aka Bell curve

Published 2014-03-15 | Author: Jake

You can use pgfplots to plot your own functions. There’s no standard macro for it, but the function isn’t too complicated and can be added as a pgfmath function.

\begin{axis}[every axis plot post/.append style={
    % All plots: from -2:2, 50 samples, smooth, no marks
  axis x line*=bottom, % no box around the plot, only x and y axis
  axis y line*=left, % the * suppresses the arrow tips
  enlargelimits=upper] % extend the axes a bit to the right and top
  \addplot {gauss(0,0.5)};
  \addplot {gauss(1,0.75)};
