Extended dataset generation possibilities of QSoas

While the main focus of QSoas is the processing of experimental data, it also features commands to generate (calculate) datasets. The command generate-buffer creates a dataset of equally spaced points (you can change their number using the option /samples) between to limiting values, as below:

QSoas> generate-buffer -2 2

By default, the $y$ values are taken equal to $x$. However, generate-buffer also takes an optional formula to directly set the $y$ values:

QSoas> generate-buffer -10 10 sin(x)

From version 2.0, it is possible to generate several datasets in a row using the /number option, and to color them using the /style option (but only since version 2.1). Each dataset is generated according to the formula, and number is a special number that starts at 0 and increases by 1 for each dataset. Here's what I used to generate the picture on the right:

QSoas> generate-buffer -2 2 sin(PI*x)**(number+1) /number=30 /style=red-to-blue
