Yep I will !

In fact the simulation start at t=0 however the "0" x axis label is not
displayed on the plot. To confirm, just zoom in at the start of the
plot.

I assume you are asking about the buffer size of a scope ; This is kind
of an optimization setting which was used before Scilab 5.4.0. Due to
the graphic re-implementation (5.4 and later) I do not see any visible
effect anymore.

The palettes and each block should be documented on the Scilab help.
