[Scilab-users] multiple plots

[grivet]

For a single plot, it is possible to choose many aspects of the plot 
using, for instance
         ha = gca();
         ha.data_bounds=[-5, -5 ; 20, 20];

Is it possible to have the same possibilities within subplots, like
         subplot(2,1,1)
         ha1 = gca();
         ha1.data_bounds=[-5, -5 ; 20, 20];
         subplot(2,1,2)
         ha2 = gca;
         ha2.data_bounds=[-1, -1 ; 2, 2];
(which does not work with Scilab 5.5/win7).

I would like to plot two different variables, with different units and 
ranges. Even more
ambitious, I would like to run different animations in each subplot.

Thank you for any suggestions.
