[scilab-Users] How to replace Matlab stairs function in Scilab

This is essentially what plot2d2 does. Extract from the doc:

Note that all the modes proposed by plot2dxx (xx = 1 to 4) can be enabled using plot2d
and setting the polyline_style option to the corresponding number.

So the options to plot2d2 are the options to plot2d... And the way you 
discovered is as valid as plot2d2.

For your example you could try:

--> plot2d2(rec(:,2), rec(:,1),leg='TAG0 Receiver')  // leg is for legend

I don't understand what the parent property is.

Regards,
Mathieu
