 After clicking on the //Create graph// button, CGRAPH displays the graph. The example shown is the Gaussian bell curve f(x) = exp(-2*x<sup>2</sup>), whose Fourier transform is again a Gaussian bell curve. In addition to the transform, the underlying function is also plotted in a different colour. After clicking on the //Create graph// button, CGRAPH displays the graph.

-Since the transform is normalised to π, the x-axis is also normalised to π. This can be changed in the settings for the [[axis parameters2D|axis parameters]].+Since the transform is normalised to π, the x-axis is also normalised to π.

 Unlike other graphics, an (optional) parameter is set here using a slider below the parameter in the default area (blue arrow). You can also enter and change the parameter as a number in the default area. Unlike other graphics, an (optional) parameter is set here using a slider below the parameter in the default area (blue arrow).
