[Scilab-users] figure with several subplots and two y-axes for each subplot

[Serge Steer]

pease find below a simplified  script which behave as expected

t = 0:0.001:0.1;
x = sin(2*%pi*50*t);
y = cos(2*%pi*50*t);

clf()

subplot(2,1,1)
plot(t,x,"b")
a=gca();
b = newaxes(); 
b.y_location = "right"; 
b.filled = "off";
b.axes_visible = ["off","on","on"];
b.axes_bounds = a.axes_bounds; 
b.font_size = a.font_size;
plot(t,y,"g")

subplot(2,1,2)
plot(t,x.*y,"b")
a=gca();
b = newaxes();
b.y_location = "right";
b.filled = "off";
b.axes_visible = ["off","on","on"];
b.axes_bounds = a.axes_bounds; 
plot(t,x+y,"g")

> So far so good. My code generates the first subplot with the two

> deletes
> the second y-axis from subplot(2,1,1). Any idea? Thanks in advance!
