The ‘Curve Composer’ task is used to autogenerate data curves of known standard shapes.
The curve is composed in two parts, a left and a right part. In the settings, the user specifies:
The number of data points (called periods)
The shape of the curve (flat, linear, standard distribution)
Initial value (first data point) and End value (last data point)
Go to Flow Gallery and Copy & Edit the Curve Composer for example usecases.
