Hi Jean,
Thanks for your answer. This solves my problem!
I reckon Scilab is an excellent and powerful mathematical software. However, it
requires a medium/deep knowledge of programming to solve a simple problem.
For example: To change some basic parameters such as: x- and y-ticks, the
Scilab users need to program some tens of (complex) code instructions:
tmp=a.x_ticks;
tmp.locations=[-12:12]';
tmp.labels=string(tmp.locations);
a.x_ticks=tmp;
tmp=a.y_ticks;
tmp.locations=[-0.4:.1:1]';
tmp.labels=string(tmp.locations);
a.y_ticks=tmp;
Why hasn't Scilab got a single code to change x- and y- parameters (e.g.,
a.x_ticks=[-12:1:12] and a.y_ticks=[-0.4:.1:1])? This could be easier for
Scilab users and makes the script be compact!
Furthermore, if I don't use the code: a.tight_limits = "on" the y-axis range is
from -0.4 to 1; however, if I use it, the y-axis range changes to -0.2 to 1.
Why?
In addition, how could I change the y-axis range (i.e., y_min and y_max)?
Thank you in advance.
All best,Reinaldo.

For example, you could use
function f=myfunction(x)
f = sin(x)./x
endfunction
// Plot
scf(1);
clf(1);
xdata = linspace ( -12, 12, 100 );
ydata = myfunction ( xdata );
plot ( xdata , ydata );
a=gca(); // obtendo o manipulador dos eixos correntes
a.tight_limits = "on";
a.grid=[1 1];
xlabel("X","fontsize",4,"color","red");
ylabel("Y","fontsize",4,"color","red");
tmp=a.x_ticks;
tmp.locations=[-12:12]';
tmp.labels=string(tmp.locations);
a.x_ticks=tmp;
tmp=a.y_ticks;
tmp.locations=[-0.4:.1:1]';
tmp.labels=string(tmp.locations);
a.y_ticks=tmp;
