[Scilab-users] Scaled plot displays in Scilab?

[Serge Steer]

You can proceed as follow. Note however that at least under windows it is not possible to create a window larger than the screen. 
Serge Steer 

clf;plot(linspace(0,100,10),linspace(0,150,10)) 

fig=gcf(); 
ax=gca(); 
ax.tight_limits="on"; 
//Dimensions of the axis in user coordinates 
ax_xu=ax.data_bounds(2,1)-ax.data_bounds(1,1); 
ax_yu=ax.data_bounds(2,2)-ax.data_bounds(1,2); 
//pixel size in mm to be determined according to screen size and resolution 
px=0.33;//conversion pixel to mm 
py=0.35;//conversion pixel to mm 
//Dimension of the axis in pixels 
ax_xp=ax_xu/px; 
ax_yp=ax_yu/py; 
//Dimension of the current portion of the canvas in pixels 
ax_Wp=ax_xp/(1-sum(ax.margins(1:2))); 
ax_Hp=ax_yp/(1-sum(ax.margins(3:4))); 
//Canvas dimensions in pixels 
fig_Wp=ax_Wp/ax.axes_bounds(3); 
fig_Hp=ax_Hp/ax.axes_bounds(4); 
//Set fig.axes_size property to have 
fig.axes_size=[fig_Wp,fig_Hp];
